NSF Releases New Extensive Climate Change Report
In a new report from the National Science Foundation, researchers outline signs of global warming discovered "from the icy expanses of the polar regions of Earth to its equatorial ecosystems."
The 114-page report titled "Solving the Puzzle: Researching the Impacts of Climate Change Around the World," addresses key research findings from the Earth elements of sky, sea, ice, land, life and people.
"Climate is a fundamental factor in ecosystem health," researchers wrote. "While most species can survive a sudden change in the weather, such as a heat wave, flood, or cold snap"”they often cannot survive a long-term change in climate."
Authors of the report point to human impacts on the environment, such as the use of fossil fuels, agriculture, land use as well as the use of aerosols as factors in the Earth's changing climate. They say it is "extremely likely that human activities have had a net warming effect since 1750.
Researchers say the evidence of a changing planet is not solely based on one field of science. They note that a wide range of scientists - from ecologists to social scientists - have documented examples of climate change's impact on the Earth.
"This report addresses some of the major questions facing climate change researchers, and how those puzzles are being addressed by NSF-funded activities," said researchers.
