Roger Pielke Jr. Weighs in on This Week’s Hysteria: Drought

I was curious
So I graphed percent of CONUS in drought according to the US drought monitor, data is weekly from 1/2000


Here from US EPA is the same data by drought category


And here from EPA is a longer time series, 1895-2020 for CONUS
Note: On this graph up means wetter, down means dryer


And here is the percent in drought (D0-D4) of the Colorado River Basin over Jan 2000 to present


And here is Colorado River Basin drought 1901-2015
via McCabe et al 2020


And for a much longer perspective, here is Colorado River Basin drought over the past 1800 years
Also from McCabe et al 2020

Here are the conclusions of McCabe et al 2020
Well worth reading carefully

And here is what the US National Climate Assessment concluded on drought in 2018


A side note
For accurately citing peer reviewed literature & US NCA on drought trends in 2013 Congressional testimony, I earned the distinction of being the only US researcher in history to be attacked by the president’s science advisor (Holdren) in a White House blog post 😎

Holdren is still wrong
The IPCC, USNCA & peer reviewed literature that they rely on is still correct

Climate change is real, and aggressive mitigation & adaptation policies make good sense

The reality of climate change doesn’t mean scientific integrity can be ignored


Oh, I guess I should point out Holdren’s false claims about me posted on White House website were basis for a subsequent Congressional investigation of me that turned my life upside down & almost ended my career
But I’m still here
And that kids is how I came to understand tenure
