Climate Change Worsening Colorado River Droughts

Climate Change Worsening Colorado River Droughts

Even as the number of Americans relying on the Colorado River for household water swells to about 40 million, global warming appears to be taking a chunk out of the flows that feed their reservoirs. Winter storms over the Rocky Mountains provide much of the water that courses down the heavily-tapped waterway, which spills through deep gorges of … Read More

As U.S. Coastal Cities Swell, Rising Seas Threaten Millions

As U.S. Coastal Cities Swell, Rising Seas Threaten Millions

That combination of rising populations and rising seas could see millions of Americans living in homes that flood regularly during the decades ahead, according to a nationwide analysis published Monday in the journal Nature Climate Change. That’s unless steps are taken to protect homes, relocate populations or redirect development into regions with… Read More

Every State’s Temperature Trend for Every Season

Every State’s Temperature Trend for Every Season

A winter heat wave is spreading inland from the West Coast and could bring unseasonable warmth spanning from coast-to-coast by the weekend. Southern California is on track to continue setting hot temperature records, Phoenix will have its earliest first 90°F day of the year, and parts of the South could see temperatures 20°-30°F above normal … Read More

The Southwest May Have Entered a ‘Drier Climate State’

The Southwest May Have Entered a ‘Drier Climate State’

The Southwest is already the most arid part of the U.S. Now new research indicates it’s becoming even more dry as wet weather patterns, quite literally, dry up. The change could herald a pattern shift and raises the specter of megadrought in the region. “We see a very intense trend in the Southwest,” Andreas Prein, a postdoctoral researcher at the … Read More

These Tiny Satellites Could Keep an Eye on Wildfires

These Tiny Satellites Could Keep an Eye on Wildfires

Close your eyes. Imagine a world where satellites smaller than a shoebox could tell you about every fire burning on earth. Now open them. You’re living in that world (or at least you will be in just a few years). NASA has announced an ambitious plan to surround the earth with hundreds of tiny satellites that could monitor wildfires in near real … Read More

Two Maps Show Why El Niño is Rising to 1997-98 Levels

Two Maps Show Why El Niño is Rising to 1997-98 Levels

In case there was any doubt, NASA has released a reminder that this El Niño is big, likely to get bigger (maybe even record-setting) and that the weather is likely to be anything but normal through this winter for much of the U.S. A new set of maps published by the NASA Earth Observatory show that oceans are getting close to replicating the 1997 … Read More

Climate Change Could Put Tribes’ Electric Systems at Risk

Climate Change Could Put Tribes’ Electric Systems at Risk

Heat waves, extreme storms, wildfire and other effects of climate change pose major threats to the electric power systems in Native American communities across the country, most significantly in the West and Southwest, according to a new U.S. Department of Energy report. “Tribes are among the communities most vulnerable to the impacts of climate … Read More

Large Wildfires Are Now More Common and Destructive

Large Wildfires Are Now More Common and Destructive

The West continues to be a fiery inferno as August starts to fade into September. Wildfires have exploded across the region this month. There have been 115 large wildfires to date including 66 large fires that are still burning. Those fires along with thousands of smaller blazes have contributed to 7.7 million acres burned in the U.S. That puts … Read More
