@irri @IFPRI @CGIAR 1/18》The scientific evidence is compelling that manmade #ClimateChange is modest and benign, CO2 emissions are beneficial rather than harmful, and the "social cost of carbon" is negative.
@IRRI's work complements the benefits of elevated CO2 for crops.
@irri @IFPRI @CGIAR 2/18》Contrary to climate industry propaganda, none of the supposed major harms of carbon emissions are actually happening. They are all merely hypothetical, and mostly implausible.

Sea-level trends have been virtually unchanged for 90+ years.

@irri @IFPRI @CGIAR 3/18》Extreme weather is not worsening.

The first type of extreme weather most people think of is hurricanes and tropical cyclones. They are not worsening. Nor are extratropical storms.
sealevel.info/learnmore.html…
@irri @IFPRI @CGIAR 4/18》Tornadoes are a big problem in the United States. They are not worsening, either.
sealevel.info/learnmore.html…
@irri @IFPRI @CGIAR 5/18》Polar bears and coral reefs are doing fine.
polarbearscience.com

In fact, the scientific data shows elevated CO2 (eCO2) is very beneficial for natural ecosystems.
@irri @IFPRI @CGIAR 6/18》Droughts are not worsening, and elevated CO2 levels mitigate drought impacts, by making plants more water efficient and drought resistant.
sealevel.info/learnmore.html…
@irri @IFPRI @CGIAR 7/18》Fires are not worsening:
sealevel.info/learnmore.html…
@irri @IFPRI @CGIAR 8/18》ALL important effects of CO2 emissions are beneficial. In fact, improved crop yields from CO2 Fertilization & drought impact mitigation from higher CO2 levels, have helped eliminate major drought-triggered famines for the first time in human history!
sealevel.info/learnmore.html…
@irri @IFPRI @CGIAR 9/18》Agronomists have done thousands of rigorous studies, measuring the benefits of elevated CO2 for agriculture. It's long-settled science: elevated CO2 is beneficial for ALL major crops. It's one of the most important reasons famines have become rare.
sealevel.info/learnmore.html…
@irri @IFPRI @CGIAR 10/18》It's impossible to overstate the importance of that blessing. Compare:
● Covid-19 has killed about 0.1% of world population, so far
● The 1918 flu killed ≈2%
● WWII killed ≈2.7%
● But the global drought & famine of 1876-78 killed an estimated 3.7% of world population
@irri @IFPRI @CGIAR 11/18》Elevated CO2 is also very beneficial for natural ecosystems. By improving crop yields eCO2 releases land from agriculture, for natural forest. But it also benefits wild plants directly. In fact, it's "greening" the Earth, especially in arid regions!
sealevel.info/learnmore.html…
@irri @IFPRI @CGIAR 12/18》This video is from NASA:
@irri @IFPRI @CGIAR 13/18》The Sahel (southern Sahara) is benefiting tremendously.

@irri @IFPRI @CGIAR 14/18》In 2009 @NatGeo reported, "Vast swaths of North Africa are getting noticeably lusher due to warming temperatures, new satellite images show, suggesting a possible boon for people living in the driest part of the continent."
sealevel.info/Owen2009_Sahar…
@irri @IFPRI @CGIAR @NatGeo 15/18》The best peer-reviewed science shows that CO2 emissions are beneficial and the "social cost of carbon" is negative.

sealevel.info/negative_socia…
@irri @IFPRI @CGIAR @NatGeo 16/18》But some scientists have worried that better crop yields from elevated CO2 (eCO2) could be accompanied by nutrient level reductions (the "dilution effect"). That can happen when soil nutrient levels are low, though it is largely mitigated with agricultural best practices.
@irri @IFPRI @CGIAR @NatGeo 17/18》In fact, food grown in greenhouses at 1500 ppmv CO2 is as nutritious as food grown outdoors at 400 ppmv CO2.

@irri @IFPRI @CGIAR @NatGeo 18/18》But agricultural best practices aren't always followed, so it's reassuring @IRRI is creating more nutritious rice. Your work should allay fears of a nutritional downside to the better crop yields from elevated CO2.

1/4. Rising CO2 levels improve plants' water use efficiency and drought resilience, through reduced stomatal conductance. Simply put, plants need to process less air to get the carbon they need for growth, and thus they lose less water to transpiration.
x.com/ncdave4life/st…

That's one of the reasons that catastrophic famines no longer happen. For all of of human history, until recently, famine was one of the great scourges of mankind: the "Third Horseman of the Apocalypse." But widespread famines are fading from living memory, and rising atmospheric CO2 concentration is one of the reasons for that.

That's a very, very Big Deal. For comparison:

● COVID-19 killed about 0.1% of the world's population
● The catastrophic 1918 flu pandemic killed about 2%
● WWII killed 2.7% of the world's population
● But the nearly-worldwide drought and famine of 1876-78 killed about 3.7% of the world's population.

2/4. Improved water use efficiency and drought resilience are especially beneficial in arid regions, like the Sahel, which is one of the reasons that region of Africa is "greening" even faster than most other places.

3/4. I asked ChatGPT about that benefit of CO2 emissions and rising CO2 levels:

"With reference to the agronomy literature, quantify how elevated CO2 helps plants use water more efficiently, and increases crops' drought resilience, by reducing stomatal conductance and water loss through transpiration."

ChatGPT replied with a very good answer:

In agronomy, the effects of elevated CO2 on plant water use efficiency and drought resilience are extensively studied. One of the key mechanisms through which elevated CO2 levels improve water use efficiency is by reducing stomatal conductance and, consequently, water loss through transpiration.

Stomata are small pores on the surface of plant leaves that regulate gas exchange, including the uptake of CO2 for photosynthesis and the release of water vapor through transpiration. When CO2 levels are elevated, plants can maintain the same or higher rate of photosynthesis while reducing stomatal conductance. This reduction in stomatal conductance leads to a decrease in water loss through transpiration without significantly affecting CO2 uptake, resulting in improved water use efficiency.

Several studies have quantified the effect of elevated CO2 on stomatal conductance and transpiration. For example, a meta-analysis published in 2013 (Kimball et al., 2013) found that under elevated CO2 levels, stomatal conductance decreased by an average of 22%, while transpiration decreased by only 17%. This indicates that plants under elevated CO2 levels were able to reduce water loss more efficiently than they reduced CO2 uptake, leading to an overall improvement in water use efficiency.

Improvements in water use efficiency due to elevated CO2 levels can increase plants' drought resilience by allowing them to maintain adequate hydration during periods of water scarcity. This can be particularly beneficial in arid and semi-arid regions where water availability is limited.

Overall, the literature suggests that elevated CO2 levels can improve water use efficiency in plants by reducing stomatal conductance and water loss through transpiration, which can enhance their resilience to drought conditions.

1/6》 Marcus, please tell me that you're not fooled by a fake "study" of a three-day-old event, from a climate industry propaganda outlet. Do you know how long real studies take?

This is the real global trend:
● sealevel.info/learnmore.html…
@Marcusgibson @WeatherProf 2/6》 NASA measures it from MODIS satellites. They show a decreasing trend in fires.
● earthobservatory.nasa.gov/images/145421/…
● archive.ph/WfDJh
● earthobservatory.nasa.gov/images/90493/r…
@Marcusgibson @WeatherProf 3/6》 The main factors affecting fires are land management and forestry practices.
● phys.org/news/2022-11-1…
● forestpolicypub.com/2021/07/30/gri…
Global warming has negligible impact on wildfires.

1/8. Gov. Newsom's press release falsely blames "a hotter, drier world." In fact, the world is warming only very slightly & slowly, and it hasn't gotten at all drier. Here're the facts:
sealevel.info/learnmore.html…
As you can see from the graph, the fraction of the globe in drought has decreased slightly, not increased.

Oh, and BTW, NCA4 (circa 2018) estimated that global average temperatures have risen only 1.14 ±0.13°C since the 1800s, and the warming is disproportionately at chilly high latitudes.Image
2/8. Also, higher CO2 levels greatly reduce drought impacts, by making plants more drought-resistant and water-efficient, through reduced stomatal conductance. That's very beneficial in arid regions, like the Sahel & much of California. Here's an article.
web.archive.org/web/2017061915…
That's is one of the reasons that region of Africa is "greening" even faster than most other places.

@NewScientist reported the "remarkable environmental turnaround," including a “quite spectacular regeneration of vegetation,” and "a 70 per cent increase in yields of local cereals such as sorghum and millet in one province in recent years."
@WeatherProf 3/8. National Geographic @NatGeo also wrote about it.

1/8》Doc wrote, "You’re not going to change my mind."

Please do not be impervious to evidence, like trillionofcells. That would make me sad.Image
2/8》Doc wrote, "Wasn’t Gleick cleared of any wrongdoing?"

No, he was not cleared. That was disinformation from The Grauniad:
x.com/ncdave4life/st…

In fact, Gleick eventually admitted the identity theft, and disseminating the forgery & the stolen documents (though only after he was caught & publicly identified).

I can see that you didn't read my article about it. You should:
sealevel.info/Peter_Gleick_D…
3/8》Gleick never admitted being the forger, but there can be no doubt of that, either.

It was the incongruous appearance of his name in the document, with the strangely flattering description of him as a "high-profile climate scientist," in a document which said NOTHING positive about ANY other climate activists, which first drew Steve Mosher's attention to Gleick. But it was the idiosyncrasies of Gleick's own writing style, found in the forged document, which Mosher mostly discussed, when explaining why he believed Gleick wrote it.

Mosher explained it, at length, in a series of blog comments, beginning here:
rankexploits.com/musings/2012/t…

Note that that was all BEFORE Gleick confessed to being the person who had impersonated the Heartland Board Member to steal the other documents. THAT iced it: there's no question that Gleick was the forger.

(BTW, Mosher used to be with Berkeley Earth.)

1/8. The IPCC authors expect  a worsening trend. No such trend is actually detectable, so far.

In fact, here's a paper about the downward  trend in hurricane destructiveness, tho I suspect the decrease might be a fluctuation rather than a durable trend.
nature.com/articles/ncomm…
2/8. The IPCC authors are sly. They know hurricanes & other tropical cyclones aren't worse, but they dodge & weave to avoid admitting it. Here's a tricky quote from AR6:

"It is likely that the global proportion of Category 3–5 tropical cyclone instances has increased over the past four decades."

ref: ipcc.ch/report/ar6/wg1…
3/8. That's a textbook illustration of Chesterton's point:

"Falsehood is never so false as when it is very nearly true."

It's "spin." It is calculated deception without QUITE lying.

Look at that graph again:
