American West Heating Twice as Fast

Let our journalists help you make sense of the noise: Subscribe to the Mother Jones Daily newsletter and get a recap of news that matters.


317488203_967e4514e6_m.jpg Don’t think climate change is going to affect you? Well, if you live in the American West, it already is. In fact the west is heating up faster than the rest of the world, reports the National Resources Defense Council. The average temperature rise in the drought-struck Colorado River basin is more than double global average—especially bad news for the 30 million people living in Denver, Albuquerque, Las Vegas, Phoenix, Los Angeles and San Diego, among the nation’s fastest growing American cities and all dependent on the Colorado for water.

The Rocky Mountain Climate Organization analyzed temperature data from the National Oceanic and Atmospheric Administration for 11 western states and found the average temp in the Colorado River Basin, from Wyoming to Mexico, was 2.2 degrees Fahrenheit hotter than the historical average for the 20th Century, and more than twice the global rise of 1.0 degree. Throughout the West, the average temperature increased 1.7 degrees. “We are seeing signs of the economic impacts,” says study author Stephen Saunders, including $2.7 billion in crop losses since 2000, commercial salmon losses, reduced hunting revenues, and shorter, less profitable ski seasons. The Colorado River Basin is in the throes of a record drought and climate scientists predict more and drier droughts in the future as hotter temperatures reduce the snowpack and increase evaporation. “We need strong leadership from western senators to pass America’s Climate Security Act,” said Spencer.

How about any leadership? You know, turning off the lights one hour a year ain’t gonna work. In 2007 I was optimistic about Earth Hour. A year later, I’m like, is this all we’re ever going to do?

IT'S NOT THAT WE'RE SCREWED WITHOUT TRUMP:

"It's that we're screwed with or without him if we can't show the public that what we do matters for the long term," writes Mother Jones CEO Monika Bauerlein as she kicks off our drive to raise $350,000 in donations from readers by July 17.

This is a big one for us. It's our first time asking for an outpouring of support since screams of FAKE NEWS and so much of what Trump stood for made everything we do so visceral. Like most newsrooms, we face incredibly hard budget realities, and it's unnerving needing to raise big money when traffic is down.

So, as we ask you to consider supporting our team's journalism, we thought we'd slow down and check in about where Mother Jones is and where we're going after the chaotic last several years. This comparatively slow moment is also an urgent one for Mother Jones: You can read more in "Slow News Is Good News," and if you're able to, please support our team's hard-hitting journalism and help us reach our big $350,000 goal with a donation today.
