the same quality of life to which Floridians |
are accustomed. For example, buildings |
may need to be designed to new standards or located farther from vulnerable |
shorelines. |

The Florida Oceans and Coastal Council has |
recommended a number of priorities for ocean |
and coastal research to improve levels of |
certainty about how climate change will affect |
Florida. These include designing and establishing realtime, interdisciplinary observing |
systems both for Florida waters and for |
contiguous waters that affect the Florida coastline, as well as further investigating ocean and |
coastal ecosystems, water quality, and tools |
and technology. To accurately predict climate |
change, it is essential to develop and use |
models that couple the atmosphere and |
oceans, and to do so on appropriately fine |
spatial scales to address the changes relevant |
to Florida. |

Intergovernmental Panel |
on Climate Change: |
The 2007 Report SummaryII. |
The Intergovernmental Panel on Climate Change, a |
scientific intergovernmental body, was established in |
1988 by the World Meteorological Organization |
and the United Nations Environment Programme. It |
is made up of a large, diverse group of scientists, |
governmental representatives, and individuals from |
around the world. It does not conduct research or |
monitoring, or make policy recommendations. |
Instead, the panel uses a scientific peer review |
process to assess the latest scientific, technical, and |
socioeconomic findings, providing decision makers |
and otherswith an objective source of information (7). |
In 2007, both the Intergovernmental Panel onClimate |
Change and former U.S. Vice President Al Gore Jr. |
were awarded the Nobel Peace Prize "for their |
efforts to build up and disseminate greater knowledge about manmade climate change, and to lay |
the foundations for the measures that are needed to |
counteract such change" (8). |
“Warming of the climate system is unequivocal, |
as is now evident from observations of increases |
in global average air and ocean temperatures, |
widespread melting of snow and ice and rising |
global average sea level.” |
Climate Change 2007: Synthesis Report (Inter |
governmental Panel on Climate Change, 2007) |
In 2007, the panel issued its fourth report on global |
climate change (previous reports were issued in |
1990, 1992, 1995, and 2001) (1). Building on |
earlier work, the report presents the findings of three |
major working groups on the physical science of |
climate; impacts, adaptation, and vulnerability; and |
mitigation. Highlights are as follows: |
Observed changes indicating global climate |
change: |
• Eleven of the last 12 years have been subject to |
the warmest temperatures since 1850. |
• Sea levels have been rising faster since 1993. |
• Satellite data show Arctic sea ice, mountain |
glaciers, and snow cover have shrunk since 1978. |
Causes of global climate change: |
• Concentrations of greenhouse gases, especially |
carbon dioxide, have increased. |
• Carbon dioxide emissions increased by 80 percent between 1970 and 2004. |
Projected global climate change and impacts: |
• Greenhouse gas emissions will continue to increase. |
• This increase will induce greater climate change in |
the 21st century. |
• Atomospheric warming of 0.4 degrees Fahrenheit |
(0.2 degress Celsius) per decade is projected. |
• Warming will likely be greatest in the northern |
latitudes. |
• Permafrost and icepacks will thaw at faster rates. |
• Increases in temperature maxima will be associated with heavier precipitation. |
• Storm intensity will likely increase; periods of |
drought may be longer. |
• Ocean acidity will increase. |
• Coastal flooding will increase due to sealevel rise |
and storms. |
• Human health will be affected by increased heat, |
floods, drought, and disease. |
• Some changes in climate could be abrupt and |
irreversible. |
Available adaptations and steps to slow the pace |
of global climate change: |
• Increase water reuse and rainwater harvesting. |
• Create natural buffers against sealevel rise. |
• Develop heathealth action plans. |
• Develop renewable energy sources; reduce |
carbon dioxide emissions. |
