@PeterGleick @MichaelEMann @PSUClimate 1/19 "Named storms" is a poor measure of destructive potential. Accumulated Cyclonic Energy (ACE) is much better. There's no sign that storms -- named or unnamed -- are getting worse.

@PeterGleick @MichaelEMann @PSUClimate 2/19 The fact that AGW has not eliminated destructive storms does not mean it is to blame for them.

@PeterGleick @MichaelEMann @PSUClimate 3/19 Anyone who can read a graph can see that AGW is not making hurricanes noticeably worse.

@PeterGleick @MichaelEMann @PSUClimate 6/19 Elevated CO2 (eCO2) isn't making weather worse, but it IS causing important changes:
Mainly, eCO2 improves crop yields & mitigates drought damage, helping making food more plentiful!

@PeterGleick @MichaelEMann @PSUClimate 7/19 This paper reports how eCO2 mitigates drought damage:
sciencedirect.com
"There have been many studies on the interaction of CO2 and water on plant growth. Under elevated CO2, less water is used to produce each unit of dry matter by reducing stomatal conductance."

@PeterGleick @MichaelEMann @PSUClimate 8/19 Virtually all crops benefit from eCO2, and most of them benefit even more when under drought stress than when under ideal conditions. Here's a paper about wheat:

@PeterGleick @MichaelEMann @PSUClimate 9/19 Most crops use C3 photosynthesis. In general, C3 crops benefit more than C4 crops, but even the most important C4 crops have been shown to benefit. Here's a paper about what elevated CO2 ("eCO2") does for corn (the most important C4 crop):

@PeterGleick @MichaelEMann @PSUClimate 10/19 eCO2 is especially beneficial for legumes, like beans, peas, and alfalfa, which are grown for their protein content. So eCO2 helps mitigate protein shortages in poor countries. Here's a paper:

@PeterGleick @MichaelEMann @PSUClimate 11/19 eCO2 is helping to make famines rare for first time in human history.
If you're too young to understand how important that is, count yourself blessed! Famine used to be a scourge comparable to war & disease.
If you're too young to understand how important that is, count yourself blessed! Famine used to be a scourge comparable to war & disease.
@PeterGleick @MichaelEMann @PSUClimate 12/19 That is BY FAR the MOST important thing: eCO2 is a major factor helping make food plentiful & famine rare.

@PeterGleick @MichaelEMann @PSUClimate 13/19 But it's not only mankind that benefits from elevated CO2 (eCO2). We'll never get CO2 to anywhere near optimum (Cretaceous/Jurassic) levels, but the modest increase so far is helping both man and nature. The Earth is greening, thanks to elevated CO2:

@PeterGleick @MichaelEMann @PSUClimate 15/19 Elevated CO2 (eCO2) is beneficial for almost all ecosystems. In fact, eCO2 even helps pine forests withstand bark beetles.

@PeterGleick @MichaelEMann @PSUClimate 16/19 The imagined major harms of manmade climate change simply are not happening. For instance, sea-level trends haven't changed significantly since the 1920s.

@PeterGleick @MichaelEMann @PSUClimate 18/19 A few years later, in 1920, Scientific American reported that experimental data showed the benefits of anthropogenic CO2 were enormous -- so great that they called it "the precious air fertilizer."

@PeterGleick @MichaelEMann @PSUClimate 19/19 Arrhenius (and Scientific American, back in its heyday) would have been astonished and horrified at the Left's anti-scientific crusade against CO2... as are the best & brightest scientists today.
