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...
Land use change is perhaps the most observable of all environmental changes. Because land use change is connected to a wide range of societal and environmental processes, a robust body of land use change research helps us understand an extensive variety...
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...
Following Hurricane Sandy, the USGS developed a science plan to support recovery, restoration and rebuilding efforts. The USGS will use Hurricane Sandy supplemental funding to implement a plan that supports mitigation activities, addresses critical gaps...
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...
