GREEN ENERGY

GREEN  ENERGY

Green power is a subset of renewable energy and represents those and technologies that provide the highest environmental benefit. defines green power as electricity produced from solar, wind, geothermal, biogas, biomass, and low-impact small hydroelectric sources. Customers often buy green power for avoided environmental impacts and its reduction benefits.



Sustainable energy is the provision of that meets the needs of the present without compromising the ability of future generations to meet their needs. energy sources are most often regarded as including all sources, such as, and It usually also includes technologies that improve. Conventional is sometimes referred to as sustainable, but this is controversial politically due to concerns about and the risks of disaster due to accident, terrorism, or.



Among sources of renewable energy, hydroelectric plants have the advantages of being long-lived—many existing plants have operated for more than 100 years. Also, hydroelectric plants are clean and have few emissions. Criticisms directed at large-scale hydroelectric plants include: dislocation of people living where the reservoirs are planned, and release of significant amounts of carbon dioxide during construction and flooding of the reservoir.

WATER EFFECT IN CHILDREN



Study suggests adverse effects on children's intellectual abilities.


A team of researchers led by Maryse Bouchard, adjunct professor at the Center for Interdisciplinary Research in Biology, Health, Environment and Society (CINBIOSE) of the Université du Québec à Montréal and a researcher at Sainte-Justine University Hospital, and Donna Mergler, professor emerita in the Department of Biological Sciences and a member of CINBIOSE, recently completed a study showing that children exposed to high concentrations of manganese in drinking water performed worse on tests of intellectual functioning than children with lower exposures. Their results are published in the prestigious scientific journal Environmental Health Perspectives, in an article entitled "Intellectual Impairment in School-Age Children Exposed to Manganese from Drinking Water"


The study, carried out by researchers at the Université du Québec à Montréal, the Université de Montréal and the École Polytechnique de Montréal, examined 362 Quebec children, between the ages of 6 and 13, living in homes supplied by with groundwater (individual or public wells). For each child, the researchers measured the concentration of manganese in tap water from their home, as well as iron, copper, lead, zinc, arsenic, magnesium and calcium. The amount of manganese from both tap water and food was estimated from a questionnaire. Finally, each child was assessed with a battery of tests assessing cognition, motor skills, and behaviour.


EFFECT IVE COMMUNICATION

EFFECT IVE COMMUNICATION

The ability to communicate effectively is essential for all aviation instructors. However, communication does not occur automatically even though the instructor has a high level of technical knowledge in a particular subject area. The beginning instructor must understand the complex process involved in communication, and become aware of the common barriers to effective communication. Mere awareness of these factors is not enough. The new instructor must also develop a comfortable style of communication that meets the goal of conveying information to students



The process of communication is composed of three elements: the source (sender, speaker, transmitter, or instructor), the symbols used in composing and transmitting the message (words or signs), and the receiver (listener, reader, or student). The three elements are dynamically interrelated since each element is dependent on the others for effective communication to take place. The relationship between instructor and student also is dynamic and depends on the two-way flow of symbols between the instructor and student. The instructor depends on feedback from the student to properly tailor the communication to the situation. The instructor also provides feedback to the student to reinforce the desired student responses.

WATER SOFT

WATER   SOFT

There are water softeners available on the market but that really aren't a good option as they only reduce the carbonate hardness without having significant impact of general hardness. They work by replacing the carbonates with sodium so that it no longer shows up on a KH test. This also will more often than not mess up your pH and require you to add back some carbonates to stabilize the situation.



All of that said, unless you are attempting to keep very sensitive fish you are far better off leaving your hardness where it is and the fish will adjust to it. Anything you do to alter hardness (especially carbonate hardness) is going to also impact the pH of the water and you will have to adjust that as well.



You can soften a little buy adding peat moss to the filter or placing driftwood in the tank. There is also a product called blackwater extract that basically does the same thing without the peatmoss on the filter

Globalization

Globalization

According to the the word 'globalization' was first employed in a publication entitled Towards New Education in 1930, to denote a holistic view of human experience in education An early description of globalization was penned by the American entrepreneur-turned-minister who coined the term 'corporate giants' in 1897 although it was not until the 1960s that the term began to be widely used by economists and other social scientists. The term has since then achieved widespread use in the mainstream press by the later half of the 1980s. Since its inception, the concept of globalization has inspired numerous competing definitions and interpretations, with antecedents dating back to the great movements of trade and empire across Asia and the Indian Ocean from the 15th century onwards

Globalization (or globalisation) describes the process by which regional economies, societies, and cultures have become integrated through a global network of political ideas through communication, transportation, and trade. The term is most closely associated with the term: the integration of national economies into the international economy through, , the spread of and presenceHowever, globalization is usually recognized as being driven by a combination of economic, technological, sociocultural, political, and biological factorsThe term can also refer to the transnational circulation of ideas, languages, or through. An aspect of the world which has gone through the process can be said to be globalized.

says globalization "is a widely-used term that can be defined in a number of different ways. When used in an economic context, it refers to the reduction and removal of barriers between national borders in order to facilitate the flow of goods, capital, services and labor... although considerable barriers remain to the flow of labor... Globalization is not a new phenomenon. It began towards the end of the nineteenth century, but it slowed down during the period from the start of the First World War until the third quarter of the twentieth century. This slowdown can be attributed to the inward-looking policies pursued by a number of countries in order to protect their respective industries... however, the pace of globalization picked up rapidly during the fourth quarter of the twentieth century

How Does The Weather Impact Fishing?

How Does The Weather Impact Fishing?

When a front passes over the river, stream or lake that you intend on fishing, it effects the behavior of the fish. Here's an example, As a cold front passes, the temperature and humidity fall and air pressure begins to rise. The passing of a cold front is generally thought to have a negative effect on fishing. I've heard many people say that fish seem to have lock-jaw immediately following a cold front. And on the other hand, the passing of a warm front often implies that inclement weather is approaching and air pressures may fall (which is important to fishermen). Many people think of warm fronts as fish catching fronts.


The weather can impact your success or failure as an angler to a much greater degree than you may think. I used to just do fishing, with no regard for how the weather might impact my fishing trip, and have since learned how big a mistake that was. We all have less and less time to actually get out fishing in the first place, so paying attention to how the weather might influence our trip is a great idea.


The examination of the weather will give us more insight into the behavior of fish than almost any other single study. Studying weather is also a great idea to help keep you out of situations like the one mentioned earlier. As we all know, being comfortable while fishing is also important and few things play a bigger role in an anglers comfort than the weather. Have you ever had the pleasure of standing in a river when the weather changes and you're not dressed for it? I know from experience that this is absolutely no fun.

El Niño is defined by shortened differences in the Northern Ocean when compared with the high value. The accepted definition is a warming or cooling of at least 10 °C (0.9 °F) averaged over the north-central arctic Pacific Ocean. Typically, this anomaly happens at irregular intervals of 2–7 years and lasts nine months to two years. When this warming or cooling occurs for only seven to nine months, it is classified as El Niño/ "conditions"; when it occurs for only five to seven months, it is classified as El Niño/La Niña "episodes"



ENSO causes extreme weather such as floods, droughts and other weather disturbances in many regions of the world. Developing countries dependent upon agriculture and fishing, particularly those bordering the Pacific Ocean, are the most affected. In popular usage, the El Niño-Southern Oscillation is often called just "El Niño". El Niño is for "the boy" and refers to the, because periodic warming in the Pacific near is usually noticed around Christmas.



Although its causes are still being investigated, El Niño events begin when part of the wide—cross the Pacific along the equator and create a pool of warm water near South America, where ocean temperatures are normally cold due to. The weakening of the winds can also create twin cyclones, another sign of a future El NiñoThe Pacific Ocean is a that drives, and the resulting change in its temperature alters weather on a global scale Rainfall shifts from the western Pacific toward the Americas, while Indonesia and India become drier.

Currently, the FDA is carefully considering the impact of matrix effects on LC/MS analysis as part of an overall review of quantitative bioanalysis. Following the Crystal City III meeting, several pharmaceutical industry leader groups met and produced  to explain the FDA recommendations regarding matrix effects. 

Over the last decade, the combination of LC and MS technologies has become a widely accepted practice for determining and quantifying specific analytes in complex biological matrices. Consequently, matrix interaction with the analyte(s) in the MS ion-source introduced new variability in quantitative analysis not seen with UV detection. This interaction was found to result in one of two phenomena: ion suppression or ion enhancement. Both may lead to variability that adversely impacts assay linearity, LLOQ reproducibility, and/or ultimately LC/MS assay validation. 

Protocols using  SPE products have been well documented and proven to limit matrix-induced ion suppression/enhancement. They efficiently remove matrix components (e.g. phospholipids) that lead to analytical variability, via a high-quality sample cleanup.

weather effects on mood

weather effects on mood

That rain is gloom and sunshine happiness is metaphorical rather than scientific, though it rings true because we humans are inherently sympathetic to our environment. But we are not its victims. Barring a mood disorder, our emotions are not casualties of the weather. The rain can be guilty by association, but not causation.

Ask a child to draw two pictures—one on a rainy day and a second in the sunshine—and you pretty much know what to expect. In the first, as blue raindrops fall from the top of the page, the stick figure behind the window is frowning. When a yellow sun beams from the corner, the stick man is smiling, with his scrawny arms in the air and colorful flowers at his feet. Evenhis stick dog wears a grin.


Though  is ambitious and offers a new perspective on research on weather's relationship to mood, it strains to draw a consensus. From the range of responses the study's subjects recorded in their journaling, the researchers determined in the end that "people differ in their sensitivity to daily weather changes."

We’ve now had two remarkable extratropical storms this year in the U.S. that have smashed all-time low pressure records across a large portion of the country. Is this a sign that these type of storms may be getting stronger? Well, there is evidence that wintertime extratropical storms have grown in intensity in the Pacific, Arctic, and Great Lakes in recent decades. I discuss the science in a post I did earlier this year.

Water conservation

Water conservation

One fundamental conservation goal is he prevalence of residential varies significantly worldwide. Recent studies have estimated that water supplies are metered in less than 30% of UK householdsand about 61% of urban Canadian homes (as of 2001) Although individual water meters have often been considered impractical in homes with private wells or in multifamily buildings, the U.S. estimates that metering alone can reduce consumption by 20 to 40 percent.

In addition to raising consumer awareness of their water use, metering is also an important way to identify and localize Some researchers have suggested that water conservation efforts should be primarily directed at farmers, in light of the fact that crop ccounts for 70% of the world's fresh water use.

 The agricultural sector of most countries is important both economically and politically, and water subsidies are common. Conservation advocates have urged removal of all subsidies to force to grow more water-efficient crops and adopt less wasteful techniques


As changing irrigation systems can be a costly undertaking, conservation efforts often concentrate on maximizing the efficiency of the existing system. This may include chiseling compacted soils, creating furrow dikes to prevent runoff, and using soil moisture and rainfall sensors to optimize irrigation schedules. Usually large gains in efficiency are possible though measurement and more effective management of the existing irrigation system.

Best time to visit is all through the year, may keep off heavy rainy days in monsoon.

WEATHER IN GOA

WEATHER  IN  GOA
Usually Goa experiences a temperate climate except during the rainy season, which lasts from June to September. It is due to the coastal Konkan region and the surroundings of Western Ghats that the weather of Goa is generally always pleasant and sunny. There are no extremes in temperature and no clear demarcations from one season to the other are found except for the monsoons

The Goan climate feature is ruled by the monsoon, which takes place between June and the end of September. Goa is in the path of the southwest monsoon, thereby experiencing a dry period lasting six to eight months of the year, followed by the annual rainfall, which occurs over the remaining four months. During the two months preceding the onset of the monsoon the humidity boosts up and the clear skies become muddled and cloudy. During the monsoon, 250cm to 300cm of rain is normal although in the Western Ghats the downpour is considerably high than on the coast. Once the monsoon has run its course the skies are clear and the weather becomes pleasant.

Goa, the tiniest state in India has 97 kilometer long coast along the Western Ghats. Goa is a very famous tourist spot. Not only does it magnetize tourists all over the world but it has also become the leading honeymoon spots in India. Its serenity, quite beaches and lush green environment admixed with its historical glory has turned on all its possibilities to become the future leader of tourist spots all over the globe.

weather forecast bangalore

weather forecast Bangalore

Bangalore's winter climate is usually quite warm, with plenty of sunny weather and blue skies. Daytime winter temperatures in Bangalore stay well above 20°C / 68°F, and usually average 26°C / 79°F or higher. However, the temperatures at night-time are known to plummet, particularly during December and January, dropping to around 15°C / 59°F, with noticeably cooler evenings. Early morning fog is also fairly commonplace at this time of the year



The climate in Bangalore is strongly affected by its elevated position, being some 950 meters / 3,117 feet above sea level. As a result of this setting, Bangalore is lucky enough to experience favourable weather throughout the year, although many people prefer to visit during its cooler, drier winter months



The plants throughout Bangalore quickly become lush and green during the monsoon weather, with the surrounding scenery soon being transformed. You can also expect low cloud cover and overcast skies on some days.

GREEN FUND

GREEN FUND
The Mexican proposal to create a Global Fund to Fight Climate Change Fund (Green) is not intended to replace, remove or replace the Kyoto Protocol, but give it more strength, dynamism and generate more action in every country in the world, said Secretary of Environment and Natural Resources, Eng. Juan Rafael Elvira Quesada.

He noted that the Green Fund aim is to expand the participation of all countries that carry out actions to promote clean development as well as to support, financially and technologically, global warming mitigation and adaptation measures. A first fund would be at least one billion dollars.

In press conference, the Secretary recalled that the creation of this fund was a proposal put forward by President Felipe Calderón, during the Americas and the Caribbean-European Union Fifth Summit , which took place in Lima, Peru, and reiterated that they will raise visibility in all international forums, since the challenge is to design a mechanism to cope with the need to implement measures for mitigation and adaptation.

GREEN REVOLUTION

GREEN    REVOLUTION

The Green Revolution created wide regional and interstate disparities[ The plan was implemented only in areas with assured supplies of water and the means to control it, large inputs of fertilizers, and adequate farm credit. These inputs were easily available in at least parts of the states of, and western thus, yields increased most in these states. In other states, such as and n areas where these inputs were not assured, the results were limited or negligible, leading to considerable variation in crop yields within these states. The Green Revolution also increased income disparities: higher income growth and reduced incidence of poverty were found in the states where yields increased the most and lower income growth and little change in the incidence of poverty in other states

The introduction of after 1965 and the increased use and are known collectively as the, which provided the increase in production needed to make self-sufficient in food grains, thus improving, once accepted as inevitable, has not returned since the introduction of Green Revolution crops. This movement is now under fire, and is blamed for the spread of Land Degradation in India due to excessive use of fertilizers, pesticides, etcOf the high-yielding seeds, wheat produced the best results. Production of coarse grains- the staple diet of the poor- and pulses -the main source of- lagged behind, resulting in reduced per capita availability (AIR) played a vital role in creating awareness for these methods. Along with high yielding seeds and irrigation facilities, the enthusiasm of farmers mobilized the idea of agricultural revolution and is also credited to All India Radio.

The standards for drinking are typically set by governments or by international standards. These standards will typically set minimum and maximum concentrations of contaminants for the use that is to be made of the water.


It is not possible to tell whether water is of an appropriate quality by visual examination. Simple procedures such as or the use of a household filter are not sufficient for treating all the possible contaminants that may be present in water from an unknown source. Even natural – considered safe for all practical purposes in the 1800s – must now be tested before determining what kind of treatment, if any, is needed. Chemical analysis, while expensive, is the only way to obtain the information necessary for deciding on the appropriate method of purification.


Water purification is a process of removing undesirable chemicals, materials, and biological contaminants from contaminated water. The goal is to produce water fit for a specific purpose. Most water is purified for human consumption (but water purification may also be designed for a variety of other purposes, including meeting the requirements of medical, pharmacology, chemical and industrial applications. In general the methods used include physical processes such as and biological processes such as or chemical processes such as and and the use of electromagnetic radiation such as

Ways to Prevent Water Pollution

Ways to Prevent Water Pollution

The reason being that about 97 percent of it is salty, and therefore undrinkable, a further 2 percent is locked in glaciers and polar ice caps, thus leaving just about 1 percent of it useful for drinking and cooking. Apart from clean drinking water, we also need to keep the waters in the oceans, rivers, and lakes unpolluted because otherwise it harms the very planet we survive on. With human populations increasing rapidly it has resulted in us polluting all the water resources of our planet, so much so, precious and unique organisms and ecosystems are being harmed and are even dying at an alarming rate.

The used water from agricultural and industrial practices, and household use create wastewater, also referred to as sewage. If this is allowed to flow back into water systems without being treated, it causes pollution, which results in harming both humans as well as animal life. Water also gets polluted when there is a runoff of rainwater from industrial, agricultural, and urban areas, which flow directly through stormwater drains into water systems without any treatment.

WATER HEATER PROBLEMS

WATER   HEATER   PROBLEMS

If you’re having problems with your electric water heater, and if you want to avoid future problems with your electric water heater, the following information will help you fix common problems and prevent future problems.

If you’ve been surprised by dirty water coming out of your hot water tap, and if your electric water heater seems to be taking much longer than it should to reheat water, more than likely your water heater has a layer of sediment in the bottom. Dirty sediment can cause problems and ultimately destroy an electric water heater, so it’s important to keep your electric water heater in top-condition by draining the sediment on a regular basis.

The outlet valve should be behind the access panel at the base of the water heater. After placing the end of the drain hose in a floor drain, working sump pump pit, or utility sink, open the drain valve, and allow the water heater to fully drain. Don’t be surprised if the draining process takes a few hours. After the water heater has fully drained, open the cold water inlet valve once again, and allow cold water to run through the water heater until the water is clean and clear.

TROPICAL RAIN FOREST PLANTS

TROPICAL  RAIN  FOREST PLANTS

Competition at ground level for light and food has lead to evolution of plants  which live on the branches of other plants, or even strangle large trees to fight for survival.

More than two thirds of the world's plant species are found in the tropical rainforests: plants that provide shelter and food for rainforest animals as well as taking part in the gas exchanges which provide much of the world's oxygen supply.

The aerial plants often gather nourishment from the air itself using so-called 'air roots';. The humidity of the rainforest encourages such adaptations which would be impossible in most temperate forests with their much drier conditions. 

Rainforest plants live in a warm humid environment that allows an enormous variation rare in more temperate climates: some like the orchids have beautiful flowers adapted to attract the profusion of forest insects.

CLIMATE IN TROPICAL FOREST

CLIMATE IN TROPICAL FOREST

The total rainfall for the year is between 1500 and 2500 mm. There is no dry season. Rain falls nearly every day. The temperature during the day is around 30ºC - 35ºC. At night it drops to between 20ºC - 25ºC. There is a little difference between the warmest and the coolest months. The relative humidity is always high. This type of climate in the tropical rain forest is known as equatorial climate.

Subtropical rainforests that lay outside of the tropics have seasonal changes in their weather. There are a couple of types of rainforests. and they are categorized by the types of weather they have during the year and where they are located. The names of these rainforests are monsoon, equatorial, and subtropical.

Many trees in the rainforest have canopies on them, providing shade for the animals and plants. The canopies help shield the plants and animals from the scorching sunlight. The rainforests are very humid due to the warm sunlight, rain and the canopies shading over the plants keeps in the moisture.

Spreading of worms in children

Spreading of worms in children


Contaminated food, water and sand/soil are major transporters for the worms in the children. It is therefore advisable to have freshly cooked and covered food. The water is to be boiled, cooled and then given to children.

Threadworms, which are also known as pinworms are tiny white worms that are fond very commonly in children. They can be seen around the anal area of a child. They are about one centimeter long, look like threads of white cotton, and hence, are named after.

Threadworms affect most of the children at some stage of their lives. Threadworms or pinworms produce a large number of micro eggs that can be carried in house dust or on clothing, bedding, bread sheet, towels etc. These tiny worms can easily be picked up by fingers and other part of the body. They then travel inside the children by mouth or any openings of the body. They locate into the intestines and develop into threadworms. They stuck to the intestines by their hook like structures and they suck up the blood and nutrients from the child’s intestines.

Are Human Activities Contributing to Climate Change?

 Are  Human  Activities  Contributing  to  Climate  Change?

Natural changes in climate result from interactions such as those between the atmosphere and ocean, referred to as internal factors, and from external causes, such as variations in the sun's energy output and in the amount of material injected into the upper atmosphere by explosive volcanic eruptions. 

Such investigations usually consist of two parts: detection of an unusual change, and attribution of all or part of that change to a particular cause or causes.  


To attribute the symptom to an underlying cause often requires additional and more complex tests, such as chemical analyses of blood and urine, or even x-rays and CAT scans. Early work on climate-change detection examined changes in the globally averaged surface temperature of the Earth over the last century. Most studies of this type concluded that the observed increase of roughly 0.5°C (about 1°F) was larger than would be expected as a result of natural climate variability alone

The further step of attributing some part of observed temperature changes to human influences makes use of climate models, which have been employed to estimate the climatic effects of a range of human-induced and natural factors. The human factors include recent changes in the atmospheric concentrations of both greenhouse gases and sulfate particles (called "aerosols"). The natural factors considered include solar variability, the effects of volcanic eruptions, and internal variability of the climate system resulting from interactions among its individual components.

Natural Causes of Global Warming

Natural Causes of Global Warming

Large volcanic eruptions can throw so much dust into the sky that the dust acts as a shield to solar radiation and causes a cooling trend in the atmosphere. You probably can’t remember such an eruption as they are rare and infrequent occurances.

As the Earth spins, it does not achieve perfect rotation. It actually wobbles slightly, thus alternately exposing the northern and southern latitudes to more and less solar radiation. This wobble in the Earth’s rotation has been causing changes in the temperature of the atmosphere for many millions of years.

Changes in the Earth’s solar radiation levels can have some impact on the Earth’s climate. Increased solar activity can cause short-term warming cycles on the Earth.

Global Warming: Causes, Effects and Solutions

Global Warming: Causes, Effects  and  Solutions

The reports, which drew on the work of more than 2,500 of the world’s leading climate scientists and were endorsed by 130 nations, confirmed the consensus of scientific opinion on the key questions related to global warming.
The report also says that global warming is likely to continue for centuries, and that it is already too late to stop some of the serious consequences it will bring. Still, the report also says there is still time to slow global warming and to lessen many of its most severe consequences if we act quickly.

The effects of global warming in the 21st century and beyond are expected to be disastrous, according to the summary of a scientific report issued on April 6, 2007, by Working Group II of the IPCC. And many of those changes are already under way.

In this report, scientists outline the costs and benefits of strategies that could reduce global warming over the next few decades. And while controlling global warming will require significant investment, the consensus of scientists who worked on the report is that nations have no choice but to take immediate action.

The UN Global Warming Report Facts and Predictions

The UN Global Warming Report Facts and Predictions

The Atlantic was particularly effected by more frequent and severe tropical cyclones, a phenomenon in line with rising surface water temperatures. The report says that there is a chance of six out of ten that recent severe storms were boosted by global warming.

Since 1900, the seasonally frozen ground in the Northern Hemisphere has shrunken by some 7 percent. This has freed large amounts of another potent greenhouse gas. To which extent such side-effects amplify ongoing global warming is not yet properly understood. The IPCC’s scenarios, therefore, do not account for eventual runaway effects that would speed up global warming

The international community will unite around policy solutions - such as the for the reduction of greenhouse gases. While all this sounds promising, global warming will still occur, albeit not beyond a range of 1.1 to 2.9 degrees Celsius. Sea level rise between 18 and 38 centimeters until the end of the century..


TROPICAL RAIN FOREST CLIMATE AND WEATHER

TROPICAL  RAIN  FOREST CLIMATE AND WEATHER

The emergent layer is the topmost portion of the rainforest, where widespread branches can absorb maximum sunlight. The is very thick and dense due to interlocked branches and it therefore forms an umbrella over other growing plants and trees. Plants under these layers receive less sunlight and so are smaller and darker. But they display a wide variety of flowers to attract insects. The forest floor level hardly receives any sunlight. Insects and fungi live there as they feed on decomposed matter on the floor. The soil is very poor but plants develop stilt or prop roots, buttress roots to absorb maximum nutrients from the soil. Lianas, strangler plants, carnivorous plants are characteristic of tropical rainforests.are also worth studying. The dense and wet rainforests make the animals develop special characteristics in order to survive, as the rule 'survival of the fittest' applies here as well.

Tropical rainforest climate is responsible for the growth of green and dense rainforests which in turn help maintain the balance of temperature and rain in other parts of the world. Once these rainforests are gone, we will be deprived of rain and pure air. Tropical rainforest climate facts are thus important from the point of view of human being's safety and survival.

TROPICAL RAIN FOREST CLIMATE

Rainforests, green biomes of the world are boon to mankind as they prevent our earth from becoming a dry desert.  are found on lofty mountains or along the seacoasts. In some parts of the world, they are widely stretched over plains or in river valleys. Rainforests are known for the greatest on the earth, as they are home to numerous species of plants and animals. Moreover, plants and animals found in each type of rain forest are quite different. Before taking a look at the tropical rainforest climate, let us take a look at what are tropical rainforests and where are they located.

The areas close to the equator are known as tropics and these areas are known for warm and humid climate, throughout the year. No other place on the earth exhibits such a variety of plants and animals, birds and insects as tropical rainforests do. Tropical rainforests are found in Central and South America, Africa, Asia and Australia. The Amazon Rain Forest in South America is the largest tropical rainforest in the world. According to the e rainforest extends over eight south American countries, namely Brazil, Bolivia, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname and Venezuela. Here follows the required information on tropical rainforest climate and weather.

TROPICAL RAIN FOREST

Indicator Animal Species

The first of these are the great apes and monkeys; of the great apes only humans really get outside of the tropics to any great extent.  A few monkeys do as well, but for the most part these are species of the tropical forests.  The Gorilla is the largest of these, the Orangutan is today confined to the shrinking forests of Sumatra and Borneo.  The Spider Monkey represents the new world monkeys which are found in the tropical rain and deciduous forests of the western hemisphere.

Toucans and their kin, like the Collared Aracari (below) are among the tropical birds adapted to feed on the profusion of fruits found in the forest.  The fruit is an energy rich diet and the birds repay the plants by passing the seeds out in another place.  Birds and monkeys both disperse seeds in this way and play a major role in maintaining the high diversity of the rainforest.

Indicator Plant Species

While it's hard to pick indicator plant species there is something that many of the tropical plants share.  That is a drip tip on the ends of the leaves (below).  This pointed tip promotes drainage from the surface of the leaf, and thus helps keep the leaf surface clean of epiphytes and fungi in the humid forest. 

One of the biggest challenges in biology is explaining the diversity of the rainforests.  Certainly the high productivity permitted by the ready availability of water combined with the warm temperatures is a factor.  The massive size of many of the trees provides a number of new habitats for animals to exploit. The extreme specialization to avoid competition is another factor.  Some scientists propose that human interference, in the guise of clearing small areas for agriculture, may play a key role as well.  And there is time; the rainforests are areas which have been relatively unaffected by the climactic shifts associated with the  glaciation which ended about 10,000 years ago. Which of these factors is most important?  Do all of them play a role? These are questions scientists are still grappling with.

RAIN FOREST CLIMATE

RAIN  FOREST  CLIMATE

The tropical rain forest is classified as Af meaning tropical forest The A is given to tropical climates that are moist for all months which have average temperatures above 18 degrees Celsius. The f stands for sufficient precipitation for all months. The latitude range for rainforest climate is 15° to 25° North and South of the equator.

The average temperature of a rain forest is about 77° Fahrenheit. The rain forest is about the same temperature year round. The temperature never drops below 64° Fahrenheit. Rain forests are so hot because they are found near the equator. The closer to the equator you are, the more solar radiation there is. The more solar radiation there is, the hotter it is. Rain forest are never found in climates which have temperatures 32° Fahrenheit and below because the plant life will not be able to live because they aren't adapted to frost. All the plants will die out if the rain forest is cooler.  

The water cycle repeats often along the equator. The main plants in this biome are trees. A lot of the rain that falls on the rain forest never reaches the ground. It stays on the trees because the leaves act as a shield, and some rain never gets past the trees to the smaller plants and grounds below.

God's Warning to the World!

God's Warning to the World!

There will be signs in the sun, moon and stars. On the earth, nations will be in anguish and perplexed at the roaring and tossing of the sea. Men will faint from terror, apprehensive of what is coming on the world, for the heavenly bodies will be shaken. At that time they will see the Son of Man coming in a cloud with power and great glory. When these things begin to take place, stand up and lift up your heads, because your redemption is drawing near.

 The first angel sounded his trumpet, and there came hail and fire mixed with blood, and it was hurled down upon the earth. A third of the earth was burned up, a third of the trees were burned up, and all the green grass was burned up.


sun and its effect

SUN AND ITS EFFECT

The short-term effects of excessive sun are serious enough by themselves. Of course, spending time in hot countries generally increases your likelihood of becoming dehydrated - a potentially serious condition - but direct sunshine can be much more dangerous.

The sun can be harmful very rapidly in some places. A hot summer sun in relatively northern climes is safe only for up to 40 minutes, and hotter areas of the world are, of course, much less safe.

The sun affects some people more than others. In particular, those with fair or freckled skin (and usually blonde or red hair). People with dark hair and dark skin are less likely to suffer from sunburn. People with black skin are likely to be not affected by the sun, and yellow and brown-skinned people are much less likely to suffer than white-skinned people. All colours of skin do burn however, given enough time.

Good Sun Exposure Effects Outweigh the Bad Effects

Good Sun Exposure Effects Outweigh the Bad Effects

 

His team has discovered for the first time that ultraviolet A (UVA) radiation and visible light are the main factors inducing malignant melanoma, the most severe type of skin cancer. But sunlight is at the same time a major, if not the first, source of vitamin D in humans, transforming precursor fatty molecules into the active vitamin. 

 

The team employed a model using data on sun radiation intensity and a vertical cylinder shape (mimicking the human body's skin surface and more realistic than flat surface exposures employed in previous researches) to assess the amount of synthesized vitamin D, depending on latitude. 

 

"In previous work, we have shown that survival rates for these cancers improve when the diagnosis coincides with the season of maximum sun exposure, indicating a positive role for sun-induced vitamin D in prognosis - or at least that a good vitamin-D status is advantageous when combined with standard cancer therapies. The current data provide a further indication of the beneficial role of sun-induced vitamin D for cancer prognosis. As far as skin cancer goes, we need to be most worried about melanoma, a serious disease with significant mortality", said Setlow. 

Effects of Sun on the Skin

Effects of Sun on the Skin 

UV exposure causes thickening and thinning of the skin. Thick skin is found in coarse wrinkles especially on the back of the neck that do not disappear when the skin is stretched.



Blood Vessel Changes Caused by the Sun
 
UV radiation causes the walls of blood vessels to become thinner leading to bruising with only minor trauma in sun-exposed areas. For example, most of the bruising that occurs on sun-damaged skin occurs on the backs of the hands and forearms not on the inside of the upper arm or even the inside of the forearm. The sun also causes the appearance of iny blood vessels, in the skin especially on the face.





UV radiation causes an increased number of moles in sun-exposed areas. Sun exposure also causes precancerous lesions called actinic keratoses that develop especially on the face, ears, and backs of the hands. The are small crusty bumps that can often be felt better than they can be seen. Actinic keratoses are felt to be premalignant lesions because 1 in 100 cases per year will develop into UV exposure also causes, which are warty looking lesions that appear to be "stuck on" the skin. In contrast to actinic keratoses, seborrheic keratoses do not become cancerous.

Effect of sun angle on climate

Effect of sun angle on climate

The amount of heat energy received at any location on the globe is a direct effect of sun angle on climate, as the at which strikes the varies by location, time of day, and due to th around the sun and the around its tilted axis. Seasonal change in the angle of sunlight, caused by the tilt of the Earth's is the basic mechanism that results in warmer weather in summer than in winter Change in is another factor. (See also ).


When sunlight shines on the earth at a lower (sun closer to the horizon), the energy of the sunlight is spread over a larger area, and is therefore weaker than if the sun is higher overhead and the energy is concentrated on a smaller area. (See Figure 1.)


The sunbeam entering at the shallower angle must also travel twice as far through the Earth's which reflects some of the energy back into space.

THE OCEAN AND CLIMATE

THE  OCEAN  AND  CLIMATE


The evolution of photosynthesis remade the Archaean Earth. Before photosynthesis, the air and oceans were anoxic. Now the air is a biological construction, a fifth of which is free molecular oxygen, and the ocean can sustain animal life even in the depths. The evolution, first of not producing oxygen] and then of oxygenic [producing oxygen] photosynthesis, sharply increased the productivity of the biosphere. Oxygenic photosynthesis sustains free oxygen in the atmosphere. In the oceans, the beneficiaries of the first photosynthetic prokaryotes [bacteria and archaea] today range from cyanobacterial and algal plankton to large kelp. Wearing plants as landsuits, from tiny mosses to giant redwoods, cyanobacteria as chloroplasts have occupied the land. The oxygen emitted has allowed the evolution of animal life, to browse the plants and, in turn, to respire the CO2 that sustains photosynthesis.
Earth is totally different from what it would be if it had no ocean. The ocean, and life in the ocean, have "constructed the planet." The ocean is an important part of the Earth System, and it influences the transformation of energy and materials important to the climate system. On the most basic level, the ocean has shaped our atmosphere. Over millions of years, the concentration of gases in the atmosphere is determined by life. If life did not exist, especially life in the ocean, earth would be very different. On a deeper level, oceanic microbes irreversibly altered the geochemistry of earth and the biogeochemical cycles of H, C, N, O and S.
Please note, there is only one ocean with many named parts. The largest parts are the Atlantic, Indian, and Pacific Oceans. Earth would be much different if there were several different disconnected oceans..
