@billmckibben @CherylBozarth The advantages of elevated CO2 for agriculture are even more important. Rising CO2 levels have raised global crop yields by at least 20%, and helped mitigate drought risks, which greatly improves global food security.

@billmckibben @CherylBozarth The best scientific evidence shows that CO2 emissions are beneficial, rather than harmful. Here are some studies:

@billmckibben @CherylBozarth Unfortunately, Bill McKibben makes his living in the Climate Business, so he's unreceptive to that good news.

@CherylBozarth @billmckibben @threadreaderapp @rattibha @threaddotblue 2/ The fact that higher CO2 levels are EXTREMELY beneficial for agriculture has been settled science for a full century. Here's a 1920 Scientific American @sciam article about it:

@CherylBozarth @billmckibben @threadreaderapp @rattibha @threaddotblue @sciam 3/ Thousands of rigorous scientific studies disprove Karin Kirk's lies. Here's a paper about wheat:

@CherylBozarth @billmckibben @threadreaderapp @rattibha @threaddotblue @sciam 4/ Here's how eCO2 benefits corn (which, significantly, is a C4 crop):
tandfonline.com/doi/abs/10.108…

@CherylBozarth @billmckibben @threadreaderapp @rattibha @threaddotblue @sciam 5/ Elevated CO2 ("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:
frontiersin.org/articles/10.33…

@CherylBozarth @billmckibben @threadreaderapp @rattibha @threaddotblue @sciam 6/ Improved global food security, in significant part thanks to the higher current CO2 level, is saving MANY lives.
sealevel.info/learnmore.html…

@CherylBozarth @billmckibben @threadreaderapp @rattibha @threaddotblue @sciam 7/ Rising CO2 levels are also highly beneficial for natural ecosystems. They're greening the Earth, especially in arid regions, like the Sahel.
sealevel.info/learnmore.html…

@CherylBozarth @billmckibben @threadreaderapp @rattibha @threaddotblue @sciam 8/ NASA measures the greening trend from satellites.

@CherylBozarth @billmckibben @threadreaderapp @rattibha @threaddotblue @sciam 9/ Here's NASA's video about it:

@CherylBozarth @billmckibben @threadreaderapp @rattibha @threaddotblue @sciam 11/ The best evidence is that manmade climate change is modest and benign, and CO2 emissions are beneifical, rather than harmful. The benefits are large and well-measured, and the supposed major harms are all merely hypothetical, and mostly implausible.
sealevel.info/learnmore.html

@CherylBozarth @billmckibben @threadreaderapp @rattibha @threaddotblue @sciam 12/ Scientists call the periods of highest temperatures "climate optimums," because they're BETTER.

That includes times substantially warmer than now, like the Eemian Optimum, which is thought to have been, on average, several degrees warmer than our current climate.

@CherylBozarth @billmckibben @threadreaderapp @rattibha @threaddotblue @sciam 13/ We'll never get anywhere near that much warming, from the effects of burning fossil fuels. We might, plausibly, get 1°C of additional warming, but probably not in your lifetime or mine. Do you understand how miniscule that is?

@CherylBozarth @billmckibben @threadreaderapp @rattibha @threaddotblue @sciam 14/ 1°C is the outdoor temperature change ("climate change") from an elevation change of ≈ 500 feet.🥱

(That's based on an average temp/altitude lapse rate of 6.5°C/km; 1000 / 6.5 = 154 meters.)

That's 2.8× the climate industry's claimed 0.36°C limit (that they call "1.5°").

@CherylBozarth @billmckibben @threadreaderapp @rattibha @threaddotblue @sciam 15/ At mid-latitudes, 1°C is about the temperature change you get from a latitude change of only 60 miles (100 km).

(How different is the climate, or the plants or wildlife, 60 miles away from where you live?)

https://t.co/35UyYkyamXsealevel.info/2015_zones_hig…

@CherylBozarth @billmckibben @threadreaderapp @rattibha @threaddotblue @sciam 16/ 1°C is less than the "hysteresis" (a/k/a "dead zone") in your home thermostat, which is probably 2-3°F. Your home's "constant" indoor temperatures are continually fluctuating that much, and you probably don't even notice it.

@CherylBozarth @billmckibben @threadreaderapp @rattibha @threaddotblue @sciam 17/ In the American Midwest, farmers can fully compensate for 1°C of climate change by adjusting planting dates by about six days.
https://t.co/KrpSfZrx9dsealevel.info/wichita_spring…

@CherylBozarth @billmckibben @threadreaderapp @rattibha @threaddotblue @sciam 18/ Growing ranges for most important crops include climate zones with average temperatures that vary by tens of °C. Major crops like corn, wheat, potatoes and soybeans are produced from Mexico to Canada. Compared to that, 1°C is negligible.

@CherylBozarth @billmckibben @threadreaderapp @rattibha @threaddotblue @sciam 19/ What's more, a fortuitous thing about global warming is that it isn't very global. It disproportionately warms frigid winter nights at high latitudes ("Arctic amplification"). The tropics warm less, which is nice, because they're warm enough already.
sealevel.info/learnmore.html…

@CherylBozarth @billmckibben @threadreaderapp @rattibha @threaddotblue @sciam 21/ The major benefits of rising CO2 levels are well-measured and extremely important.

The major harms are all merely hypothetical, and mostly implausible. They're just climate industry marketing FUD.

@CherylBozarth @billmckibben @threadreaderapp @rattibha @threaddotblue @sciam 22/ None of the supposed major harms predicted to result from manmade climate change are actually happening.
sealevel.info/learnmore.html…

@CherylBozarth @billmckibben @threadreaderapp @rattibha @threaddotblue @sciam 23/ MOST importantly: Rising CO2 levels are helping to make famines rare for the first time in human history!

Famine is the Third Horseman of the Apocalypse. Throughout all of human history, famine (usually due to drought) was a Damoclean sword hanging over mankind — until now!

@CherylBozarth @billmckibben @threadreaderapp @rattibha @threaddotblue @sciam 24/ When I was a child, horrific famines were often in the news, in places like Bangladesh. But Bangladesh and India now have food surpluses, every year.

Rising CO2 level is one of the major reasons.

sealevel.info/learnmore.html…

@CherylBozarth @billmckibben @threadreaderapp @rattibha @threaddotblue @sciam 25/ Here's what CO2 & manmade climate change are doing in Africa. This is what climate activists are campaigning against:

“’Before, there was not a single scorpion, not a single blade of grass… Now you have people grazing their camel…"
https://t.co/qNvm4AjMqlsealevel.info/Owen2009_Sahar…

@CherylBozarth @billmckibben @threadreaderapp @rattibha @threaddotblue @sciam 26/ Here's another article about it:

sealevel.info/Pearce2002_Afr…

@CherylBozarth @billmckibben @threadreaderapp @rattibha @threaddotblue @sciam 27/ Ending famine is a VERY Big Deal, comparable to ending war and disease. Compare:

● Covid-19 killed 0.1% of world population.
● 1918 flu pandemic killed about 2%.
● WWII killed 2.7%.
● The near-global drought & famine of 1876-78 killed about 3.7% of the world population.

@CherylBozarth @billmckibben @threadreaderapp @rattibha @threaddotblue @sciam 28/28 So the question is, Cheryl, do you care?

Do you care that you're campaigning for a harsher, browner world? Do you care that you are campaigning for a poverty and famine? Do you care how many people your decarbonization policies would kill?

@billmckibben @threadreaderapp @rattibha @threaddotblue @sciam Thanks to Arctic Amplification, the global average temperature increase was probably only 1/4 to 1/3 that large & that rapid. But it still dwarfed recent rates of warming by about an order of magnitude.

Mankind & nearly all other existing species all survived those very rapid warming events.

@billmckibben @threadreaderapp @rattibha @threaddotblue @sciam Past (natural): ≥1½°C/decade = rapid and large, and harmless

Current/recent (manmade): 1½°C/century = slow and slight, but climate industry claims it's a catastrophe

@billmckibben @threadreaderapp @rattibha @threaddotblue @sciam 4} It's easy for you to dismiss the benefits of a rising crop yields, mitigated drought impacts, and a greening planet, if you're not one of the people whose lives depend on those benefits.

https://twitter.com/ncdave4life/status/1673212447295979520

@billmckibben @threadreaderapp @rattibha @threaddotblue @sciam 5} The scientific evidence is compelling that manmade climate change is modest & benign, CO2 emissions are very beneficial, and the "social cost of carbon" is negative.

Climate Industry marketing pretends otherwise, because they have a product to push.

@billmckibben @threadreaderapp @rattibha @threaddotblue @sciam Yes, "rates of change matter," but I've showed you that the rate of anthropogenic climate change is miniscule compared to past natural climate change episodes.

The reason you didn't already know that is your habit of only getting information from one side
