Hot and Getting Hotter: Heat Islands Cooking U.S. Cities

Cites are almost always hotter than the surrounding rural area but global warming takes that heat and makes it worse. In the future, this combination of urbanization and climate change could raise urban temperatures to levels that threaten human health, strain energy resources, and compromise economic productivity. Summers in the U.S. have been … Read More

Here’s How Arctic Sea Ice Could Shrink Even More

Climate change is the main driver behind receding Arctic sea ice. As summer ice shrinks further, it’s causing a host of other changes including the growth of large waves in the previously iced-over areas. Those waves could potentially hasten the demise of sea ice, leading to further changes in the fragile region. Changes brought on by global warmi… Read More
