McGuire Center for Lepidoptera and Biodiversity

McGuire Center for Lepidoptera and Biodiversity

The center houses a collection of more than six million butterfly and moth specimens, making it one of the largest collections of in the world, rivaling that of the in . The collection includes extinct species. It started with around four million specimens, with space for significant further expansion. The collection brings together those from the  in other University of Florida collections, and the 's Division of Plant Industry collections.

A $4.2 million gift was received from William and Nadine McGuire of Wayzata, Minnesota in 2000 to establish the William W. and Nadine M. McGuire Center for Lepidoptera and Biodiversity. This gift was one of the largest private gifts ever given to foster research on insects and was matched from the State of Florida Alec Courtelis Facilities Enhancement Challenge Grant Program The McGuires later gave another $3 million to fund final construction of the center. This new $12 million facility fo research and public exhibits opened in August 2004.

The research space includes laboratories focusing on molecular genetics, scanning electron microscopy, image analysis, conservation and captive propagation of endangered species, optical microscopy and specimen preparation, as well as classrooms and offices for 12 faculty curators, collection managers and other staff.
Some of the research laboratories and collection can be viewed through glass panels at the back of the museum. The center has around 39,000 square feet (3,600 m2) of space for its facilities in total.

"The functions of the Florida Museum of Natural History, located at the University of Florida, are to make scientific investigations toward the sustained development of natural resources and a greater appreciation of human cultural heritage, including, but not limited to, biological surveys, ecological studies, environmental impact assessments, in-depth archaeological research, and ethnological analyzes, and to collect and maintain a depository of biological, archaeological, and ethnographic specimens and materials in sufficient numbers and quantities to provide within the state and region a base for research on the variety, evolution, and conservation of wild species; the composition, distribution, importance, and functioning of natural ecosystems; and the distribution of prehistoric and historic archaeological sites and an understanding of the aboriginal and early European cultures that occupied them.

State institutions, departments, and agencies may deposit type collections from archaeological sites in the museum, and it shall be the duty of each state institution, department, and agency to cooperate by depositing in the museum voucher and type biological specimens collected as part of the normal research and monitoring duties of its staff and to transfer to the museum those biological specimens and collections in its possession but not actively being curated or used in the research or teaching of that institution, department, or agency.
The Florida Museum of Natural History is empowered to accept, preserve, maintain, or dispose of these specimens and materials in a manner which makes each collection and its accompanying data available for research and use to the staff of the museum and by cooperating institutions, departments, agencies, and qualified independent researchers.

Florida Museum of Natural History

The museum was founded in 1891 and relocated to the campus of the University of Florida in 1906 and was chartered as the state's official by the Florida Legislature in 1917. Formerly known as the Florida State Museum, the name was changed in 1988 to more accurately reflect the museum's mission and help avoid confusion with which is located in.

The main public exhibit facility, Powell Hall and the attached McGuire Center, are located in the Cultural Plaza, which it shares with the and the The main research facility and former public exhibits building, Dickinson Hall, is located on the east side of campus at the corner of Museum Road and Newell Drive.

Powell Hall's permanent public exhibits focus on the flora, fauna, fossils and historic peoples of the state. The museum does not charge for admission to most exhibits; the exceptions are the Butterfly Rainforest and certain traveling exhibits.

The Florida Museum of Natural History is the State of Florida's official state-sponsored and chartered natural history museum. Its main facilities are located on the campus .

Global warming health effects

Global warming health effects

Severe heat waves -- characterized by stagnant masses of warm air and consecutive nights with high minimum temperatures -- will intensify in the United States and Canada, according to the data on North America released Monday by the United Nations

Intergovernmental Panel on Climate Change.

 Higher temperatures over the coming decades are expected to cause more smoggy days and heat waves, contributing to a greater number of illnesses and deaths in the United

States, according to international climate scientists.

Just how much people and ecosystems suffer in North America, scientists reported, depends on how well greenhouse gases are controlled. And, the scientists cautioned, it depends on how well they plan for and try to prevent the damage.


Global warming is already affecting people's health, said Kristi Ebi, an epidemiologist from Virginia and lead author of a chapter on human health written for the international science panel.

U.N. Framework Convention on Climate Change (UNFCCC)

U.N. Framework Convention on Climate Change (UNFCCC)

On June 12, 1992, 154 nations signed the UNFCCC, that upon ratification committed signatories' governments to a voluntary "non-binding aim" to reduce atmospheric concentrations of greenhouse gases with the goal of "preventing dangerous anthropogenic interference with Earth's climate system." These actions were aimed primarily at industrialized countries, with the intention of stabilizing their emissions of at 1990 levels by the year 2000; and other responsibilities would be incumbent upon all UNFCCC parties. The parties agreed in general that they would recognize "common but differentiated responsibilities," with greater responsibility for reducing greenhouse gas emissions in the near term on the part of developed/industrialized countries, which were listed and identified in Annex I of the UNFCCC and thereafter referred to as "Annex I" countries.

On September 8, 1992, the US president transmitted the UNFCCC for advice and consent of the U.S. Senate to ratification. The Foreign Relations Committee approved the treaty and reported it (Senate Exec. Rept. 102-55) October 1, 1992. The Senate consented to ratification on October 7, 1992, with a two-thirds majority vote. President Bush signed the instrument of ratification October 13, 1992, and deposited it with the U.N. Secretary General.

According to terms of the UNFCCC, having received over 50 countries' instruments of ratification, it entered into force March 21, 1994.


 

United Nations Framework Convention on Climate Change

United Nations Framework Convention on Climate Change

The UNFCCC was opened for signature on May 9, 1992, after an Intergovernmental Negotiating Committee produced the text of the Framework Convention as a report following its meeting in New York from April 30 to May 9, 1992. It entered into force on March 21, 1994. As of December 2009, UNFCCC had

One of its first tasks was to establish of (GHG) emissions and removals, which were used to create the 1990 benchmark levels for accession of Annex I countries to the Kyoto Protocol and for the commitment of those countries to GHG reductions. Updated inventories must be regularly submitted by Annex I countries.

The United Nations Framework Convention on (UNFCCC or FCCC) is an international environmental produced at the Conference on Environment and Development (UNCED), informally known as the held in from June 3 to 14, 1992. The objective of the treaty is to stabilize greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous interference with the climate system

The treaty itself sets no mandatory limits on greenhouse gas emissions for individual countries and contains no enforcement mechanisms. In that sense, the treaty is considered legally non-binding. Instead, the treaty provides for updates (called "protocols") that would set mandatory emission limits. The principal update is the which has become much better known than the UNFCCC itself.

Ozone depletion

Ozone depletion

Column ozone losses could exceed 20% globally, 25–45% at mid-latitudes, and 50–70% at northern high latitudes persisting for 5 years, with substantial losses continuing for 5 additional years. Column ozone amounts would remain near or below 220 at all latitudes even after three years, constituting an extra-tropical “ozone hole”. Human health ailments like cataracts and skin cancer, as well as damage to plants, animals and ecosystems at mid-latitudes would likely rise sharply as ozone levels decreased and allowed more harmful UV light to reach Earth, according to the PNAS study. This study demonstrates that a small-scale, regional nuclear conflict is capable of triggering ozone losses even larger than losses that were predicted in the 1980s following a full-scale nuclear war. The missing piece back then was that the models at the time could not account for the rise of the smoke plume and consequent heating of the stratosphere.

A 2008 study published in found that a nuclear weapons exchange between Pakistan and India using their current arsenals could create a near- global ozone hole, triggering human health problems and wreaking environmental havoc for at least a decade. The computer-modeling study looked at a nuclear war between the two countries involving 50 Hiroshima-sized nuclear devices on each side, producing massive urban fires and lofting as much as five million metric tons of soot about 50 miles (80 km) into the stratosphere. The soot would absorb enough solar radiation to heat surrounding gases, setting in motion a series of chemical reactions that would break down the stratospheric ozone layer protecting Earth from harmful ultraviolet radiation
