Science - including world leading atmospheric research - keeps our nation strong, and our citizens safe. Let’s move beyond politicizing it. Let’s move beyond the BS and put our citizens and the health of our nation/planet first. bigpivots.com/was-this-cli...

To heat a home: “Most importantly, gas heating can’t beat the efficiency of heat pumps... Even at temperatures below 15F, heat pumps can slash $100’s off the average home’s heating bill in most places in the US” www.washingtonpost.com/climate-envi...

Just get outdoors: “If you find yourself out in the middle of the metaphorical river, struggling amid the digital flood, I urge you to try to get out. Maybe find a real live stream to visit. I hope it has trout & is lined with raspberry bushes, thorns and all” www.washingtonpost.com/opinions/202...

Read about the latest climate science & the CO River - see Chapter 2, written by me and Brad Udall, >50 years of combined thinking about the River & why the flows of this "lifeblood of the Southwest" are declining. Good news is that we can stop it.

My take on a dismal CO River situation - declining flows are creating a short-term crisis, & the need for a better longterm plan. "climate change is the biggest enemy of good flows in the CO River, &, for that matter, the whole climate of the SW & West"

A conversation with Jonathan Overpeck - Big Pivots
Climate scientist explains how we're stacking the odds for lesser Colorado River flows. Still, we may need the big dams even more.

Here's one of the latest forecasts for the current CO River water year. Super bad. The river allocation system is clearly breaking, and climate change isn't helping at all.

Flows on the Colorado River this year look grim, and that means we could be Dancing With Deadpool as reservoir levels in Lakes Mead and Powell reach unprecedented/dangerously low levels. What to do? Here are some ideas, just out from a pile of experts...

While the Pacific Northwest (and soon NCal) gets hammered by climate change supercharged rain, snow and flooding, the US SW megadrought is at 26 years a counting. No relief in sight.

To give you an idea of why rivers are so swollen and flooding is historic, look no further than the high elevation rain/ snow. Up to 30” of precip has fallen in 2 weeks atop the mountains east of #Seattle
Much more on the way over the next 2 weeks.
