  • "Birds are laying eggs earlier than usual, plants are flowering earlier and mammals are breaking hibernation sooner," said Terry L. Root, a senior fellow with Stanford's Institute for International Studies (IIS) and lead author of the Jan. 2 Nature study.

  • Question: What Causes Global Warming?Answer: Scientists have determined that a number of human activities are contributing to global warming by adding excessive amounts of greenhouse gases to the atmosphere. Greenhouse gases such as carbon dioxide accummulate in the atmosphere and trap heat that normally would exit into outer space.

  • While many greenhouse gases occur naturally and are needed to create the greenhouse effect that keeps the Earth warm enough to support life, human use of fossil fuels is the main source of excess greenhouse gases. By driving cars, using electricity from coal-fired power plants, or heating our homes with oil or natural gas, we release carbon dioxide and other heat-trapping gases into the atmosphere. Deforestation is another significant source of greenhouse gases, because fewer trees means less carbon dioxide conversion to oxygen.

  • There are lots of reasons to be concerned about this trend, not the least of which is the amplification of global warming through a positive feedback. (Since ice is a lot more reflective of sunlight than ocean water, melting sea ice allows more heat from the Sun to be absorbed instead of reflected, causing temperatures to rise more rapidly, thus melting more ice, and so forth, creating a positive feedback and raising the Earth’s reflectivity, also known as its albedo.)

  • When it comes to connecting the dots between climate change, extreme weather and health, the lines are clear. The earth is saying something with record heat, drought, storms and fire. Scientists are telling us this is what global warming looks like
  • Climate change will have a significant impact on the sustainability of water supplies in the coming decades. A new analysis, performed by consulting firm Tetra Tech for the Natural Resources Defense Council (NRDC), examined the effects of global warming on water supply and demand in the contiguous United States. The study found that more than 1,100 counties -- one-third of all counties in the lower 48 -- will face higher risks of water shortages by mid-century as the result of global warming. More than 400 of these counties will face extremely high risks of water shortages. Read more »
  • Each year American power plants pump more than two billion tons of carbon dioxide into the air. EPA's new standards would reduce carbon pollution and protect public health. Read more »
