Global climate models project that near the end of the 21st century, average surface temperature over most of Earth’s surface will be several degrees warmer than today, mainly due to rising levels of greenhouse gases in the atmosphere.
NOAA researchers have built a "time machine" for weather that provides detailed snapshots of the global atmosphere from 1891 to 2008. The system's ability to "hindcast" past weather events is emerging as a powerful new tool for detecting and quantifying climate change.
At the United Nations Climate Change Conference, Dr. Alexander E. “Sandy” MacDonald, of NOAA, used Science on a Sphere® to illustrate how climate change will transform the planet if humans do not reduce emissions of greenhouse gases.
Rhode Island's coasts are already feeling the impacts of rising seas. The Rhode Island Coastal Resources Management Council and Rhode Island Sea Grant are working with the legislature to explicitly address sea level rise and climate change in the state's building code.
Carbon dioxide is everywhere: in the air, rising from cracks in the ocean floor, and in your soda can. Now it's showing up in the news! Find out why carbon dioxide is such a hot topic, and why it's going to be around for a long, long time.
The figure summarizes some of the key variations amongst the six illustrative scenarios used by the Intergovernmental Panel on Climate Change (IPCC) in considering possible future emissions of greenhouse gases during the 21st century.
