@pjholloway I have very good news for you, Paul: David Wallace-Wells @dwallacewells's book is 100% nonsense. The scientific evidence is compelling that manmade #ClimateChange is modest and benign, and CO2 emissions are highly beneficial, just as Arrhenius predicted.

@pjholloway @dwallacewells None of the hypothesized major harms from manmade climate change are actually happening.

Sea-level rise has not significantly accelerated.

@pjholloway @dwallacewells There is ONE major climate change, which is actually happening, due to carbon emissions. NASA measures it, from satellites:

Rising CO2 levels are greening the Earth.

@pjholloway @dwallacewells This is NASA's video about it.

@pjholloway @dwallacewells It is especially beneficial for the world's most vulnerable people, who live in arid regions, where agriculture is difficult and famines used to be frequent, like the Sahel.

Here's @NewScientist reporting the "remarkable environmental turnaround."

@pjholloway @dwallacewells @newscientist Note their report of "70% increase in yields of local cereals such as sorghum and millet in one province in recent years." Those are C4 plants.
It was once thought that C4 plants would benefit little from rising CO2 levels. But C4 crops are favored for their drought-hardiness…

@pjholloway @dwallacewells @newscientist …and elevated CO2 is especially beneficial under dry conditions, even for C4 crops.

(Most crops are C3, and they benefit even more.)

@pjholloway @dwallacewells @newscientist None of the supposed major negative impacts of elevated CO2 are actually happening, to a detectable degree. But higher CO2 levels are extremely beneficial for the Earth's ecosystems, especially in arid regions:

@pjholloway @dwallacewells @newscientist Those benefits are especially impactful in sub-Saharan Africa. Here's another article from New Scientist @NewScientist:

@pjholloway @dwallacewells @newscientist Even National Geographic @NatGeo noticed (though they've since scrubbed this article from their website):

@pjholloway @dwallacewells @newscientist @NatGeo In addition to benefiting natural ecosystems, elevated CO2 is extremely beneficial for agriculture. It makes agriculture more productive, and less vulnerable to droughts. That improves global food security, saves lives, and lowers food prices.

@pjholloway @dwallacewells @newscientist @NatGeo Rising CO2 levels have increased global agricultural productivity by about 20%, so far, and as CO2 levels continue to rise so does that figure.

@pjholloway @dwallacewells @newscientist @NatGeo Not only does CO2 make crops more productive & food more plentiful, through "CO2 fertilization," thus freeing land from agricultural use for reforestation, it also helps avert famines by mitigating drought impacts.

@pjholloway @dwallacewells @newscientist @NatGeo Rising CO2 levels hare helping to make famines rare, for the first time in human history.

@pjholloway @dwallacewells @newscientist @NatGeo Paul, I hope this information cures the depression which David Wallace-Wells @dwallacewells's shamefully misleading book induced. If you have any questions, do not hesitate to reach out to me.

BTW, great job on this tweet:
