@heat_meiser @KHayhoe The Left / Democrat / Hayhoe assault on science continues, emboldened by anticipation of reinforcements coming in January. But reality stubbornly refuses to cooperate with their disinformation campaign.

@heat_meiser @KHayhoe Overwhelming scientific evidence shows that CO2 emissions are highly beneficial, rather than harmful. We'll never get CO2 anywhere near optimum (Cretaceous/Jurassic) levels, but the modest increase so far is helping both man and nature. NASA measures it:
@heat_meiser @KHayhoe The Earth is greening, thanks to elevated CO2:

@heat_meiser @KHayhoe The scientific evidence is overwhelming that manmade climate change is modest and benign, and CO2 emissions are highly beneficial.
The major harms are all hypothetical, and mostly implausible. The major benefits are proven, measured, and very large.
@heat_meiser @KHayhoe eCO2 improves crop yields and mitigates drought impacts. That's helping make famines rare for first time in 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.
@heat_meiser @KHayhoe The only PROVEN significant effects of rising CO2 levels are BENEFICIAL: rising crop yields, mitigation of drought damage, greening ecosystems, more plentiful food supplies, and the almost complete elimination of famines:

@heat_meiser @KHayhoe Here's a paper, reporting how eCO2 mitigates drought damage:
sciencedirect.com/science/articl…
"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."
@heat_meiser @KHayhoe Elevated CO2 (eCO2) is highly beneficial for almost all ecosystems. In fact, eCO2 even helps pine forests withstand bark beetles.

@heat_meiser @KHayhoe It's not just trees that benefit from eCO2. Virtually all crops benefit, and most of them benefit even more when under drought stress than when under ideal conditions. Here's a paper about wheat:

@heat_meiser @KHayhoe You want the big picture? Well, here it is: CO2 is one of the major factors making food plentiful and famine rare.

@heat_meiser @KHayhoe The imagined major harms of manmade climate change simply are not happening. For instance, sea-level trends haven't changed significantly since the 1920s.

@heat_meiser @KHayhoe Rising CO2 levels have not made hurricanes or other storms detectably worse, nor droughts, nor fires, nor has it caused any other significant harms, thus far.
Here's a graph, of hurricane frequencies (which obviously are not worsening):

@heat_meiser @KHayhoe Here's an article about the declining frequency of strong tornadoes:

@heat_meiser @KHayhoe If you were unaware of those facts, it is a sign that you have not been reading balanced information. You won't get it from @KHayhoe, but I can help you with that problem.
@heat_meiser @KHayhoe Unfortunately, the Left has subverted many fields, substituting politics and special interest propaganda for sound science. In fact, many fields are now dominated by complete crackpottery.
