Climate Change

We are certain that the Earth's climate is changing because of the trends that we see in the instrumented climate record and the changes that have been observed in physical and biological systems.  The instrumental record of climate change is derived...
Not specifically. Our charge is to understand characteristics of the earth, especially the earth's surface, that affect our Nation's land, water, and biological resources. That includes quite a bit of environmental monitoring. Other agencies, especially...
The link between land use and the climate is complex.  First, land cover, as shaped by land use practices, affects the global concentration of greenhouse gases. Second, while land use change is an important driver of climate change, a changing climate...
No one knows for sure what would happen if the snow and ice in the polar regions all melted. Sea level would rise, which would flood coastal regions. Climate would be affected worldwide. Isostatic rebound would occur where ice masses were removed from...
Yes. Some of these areas include large, heavily populated deltas, low-lying islands, Arctic communities and other indigenous communities that live along the coastline or on islands, water-scarce areas of the world that are getting drier, regions that are...
With increasing global surface temperatures the possibility of more droughts and increased intensity of storms will likely occur. As more water vapor is evaporated into the atmosphere it becomes fuel for more powerful storms to develop. More heat in the...
Land-use change is one type of human activity that is causing changes in Earth’s climate. This excerpt, taken from the World Meteorological Organization’s website gives a short explanation of how land-use change alters the climate system: “Land-use...
There are a variety of very good websites with climate change information, including the following: USGS Climate and Land Use Change USGS National Climate Change Viewer Intergovernmental Panel on Climate Change U.S. Global Change Research Program World...
• Temperatures are rising world-wide due to greenhouse gases trapping more heat in the atmosphere. • Droughts are becoming longer and more extreme around the world. • Tropical storms becoming more severe due to warmer ocean water temperatures. • As...
Scientists have predicted that long-term effects of climate change will include a decrease in sea ice and an increase in permafrost thawing, increase in heat waves and heavy precipitation, and decreased water resources in semi-arid regions. Below are...
