On Wednesday we explored the definitions of climate change and global warming as well as some of the causes. For reference, the U.S. Environmental Protection Agency (EPA) says that “[c]limate change refers to any significant change in the measures of climate lasting for an extended period of time. In other words, climate change includes major changes in temperature, precipitation, or wind patterns, among other effects, that occur over several decades or longer.” Learn more about climate change with the EPA’s “Climate Change Facts: Answers to Common Questions” page.
So what does this mean for our day to day lives? According to the National Aeronautics and Space Administration (NASA), “[g]lobal climate change has already had observable effects on the environment. Glaciers have shrunk, ice on rivers and lakes is breaking up earlier each season, plant and animal ranges have shifted and trees are flowering sooner. The effects that scientists predicted would result from global climate change are now occurring: loss of sea ice, accelerated sea level rise and longer, more intense heat waves.” Learn more about the effects of climate change here.
If you would like more information about the science behind climate change, check out the EPA’s science site. For short informational films on various aspects and effects of climate change, check out NASA’s “Climate Reel”.
If you are interested in learning what “key indicators,” scientists use when monitoring climate change, such as global surface temperature, this NASA site should prove useful. For specific evidence of climate change, check out NASA’s “Evidence” site which seeks to answer the question, “Climate change: How do we know?”.
