Understanding Climate's Influence on Human Evolution
The hominin fossil record documents a history of critical evolutionary events that have ultimately shaped and defined what it means to be human, including the origins of bipedalism; the emergence of our genus Homo; the first use of stone tools; increases in brain size; and the emergence of Homo sapiens, tools, and culture.
Cities Affect Global Weather Currents
The heat emanating from large metropolitan areas may be changing weather patterns thousands of miles away. A composite image of Earth at night, compiled from over 400 satellite images, shows the locations of major cities, which new research suggests can have far-reaching effects on temperature.Watch 131 Years of Global Warming in 26 Seconds
Don't Have Flash? Watch this video on your iPad or iPhone here While temperatures soared for many this summer, this video takes the longer historical view. It comes to us from our friends at NASA and is an amazing 26-second animation depicting how temperatures around the globe have warmed since 1880. That year is what scientists call the beginning of the “modern record.” You’ll note an acceleration of those temperatures in the late 1970s as greenhouse gas emissions from energy production increased worldwide and clean air laws reduced emissions of pollutants that had a cooling effect on the climate, and thus were masking some of the global warming signal.
