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.

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. @Panta_Rhei06 @simonmaechling --

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.

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 Β±0.13Β°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.

1/5. I trust that it is obvious to you that the most important effects of climate change are on agriculture. Right?

So if you really want to read the best relevant scholarly literature, you should start with agronomy papers. Agronomy is a much older, more rigorous, and less politicized field than "climate science," and it's the field which studies the effects of CO2 and climate change on agriculture.



Here are "cereal crops" (wheat, corn, rice, etc.), averaged:

If you call incoming fluxes positive and outgoing fluxes negative, then an "energy imbalance" simply means incoming plus outgoing fluxes do not sum to zero.

Persistent energy imbalance causes temperature change. That gives us clues to estimate EEI.

1/15≫ Dr. Belch (why oh why isn't she a gastroenterologist?) seems not to recognize the significance of the story.

Climate activists predicted that if Earth's average temperature got to 1.5Β°C above the pre-industrial (late Little Ice Age) baseline it would be a disaster. But they did, and nothing bad happened.

The significance of that is that it means the climate activists were completely wrong. 2/15≫ In case you're wondering, the 4 known factors which caused 2023 to be so mild were:

1. A strong El NiΓ±o spike. And

2. IMO 2020 shipping regulations drastically reduced sulfate aerosol air pollution (The IMO says they resulted in "an estimated 46% decrease in ship-emitted aerosols," which equates to a sudden 10% decrease in total global SO2 emissions, which is a large improvement in a short time, with a significant warming effect). And

3. The unusual 2022 Hunga Tonga eruption, which humidified the stratosphere. And

4. Also a little bit of warming from the ongoing slow rise in atmospheric CO2 levels (though only about 25 ppmv/decade).

It's all good, though (unfortunately) #1 & #3 are temporary.

1/7. This PBS piece is extremely misleading. Elevated CO2 greatly improves crop yields, and it mitigates drought impacts, by improving plants' water use efficiency (WUE) and drought resilience. See:


I asked ChatGPT to explain the mechanism by which agronomists have found that elevated CO2 improves crops' WUE and drought resilience. It did a good job:
‍‍‍‍‍‍ ‍‍
‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍ ‍‍‍‍‍‍ ‍‍꧁꧂

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.masterresource.org/carbon-dioxide…Image 2/7. Contrary to climate industry propaganda and misinformation from the leftists at PBS, the scientific evidence is compelling that CO2 emissions and rising CO2 levels are beneficial.

1️⃣/4️⃣. That graph shows an estimate of a total of about 500 ZJ added to the the upper 2 km of the oceans since 1955.

Aside: Actually, the first 50 years of the graph are nothing but guesses.

OHC is estimated by models, informed by temperature measurements, made by Argo floats. The first Argo float was deployed in 2000. They didn't reach 3000 units (i.e., one float per 120,000 kmΒ²) until 2007.

So the part of their graph prior to about 2005 is 100% codswallop. The kindest thing you can say about it is that it's a plausible guess, consistent with (but you can't say based upon!) convenience samples of sea surface temperatures. It is not data, in any sense.

But never mind that, because that graph also has another problem... 2️⃣/4️⃣. Does it seem odd to you that, even though all the measurements are of temperature, rather than heat content, THEY NEVER REPORT TEMPERATURES?

You should calculate what 500 ZJ means in terms normal people can grok: average water temperature change. If you do that simple exercise, it will be obvious why they do not report it.

I've also already explained to you why the natural sinks which remove CO2 from the air will continue to accelerate as long as CO2 levels continue to rise.
3/7. Natural CO2 removal mechanisms, which already remove at least (5.4 Gt CO2 / 2.1294 Gt/ppmv) = 2.5 ppmv/year, accelerate by an additional 1 ppmv/year for every 40-50 ppmv increase in atmospheric CO2 concentration.


That's a very powerful "negative feedback" which limits the rise in CO2 concentration, and ensures that the temperature increase will remain modest and benign.
