1/5. If you learn about agronomy from climate-activist journalists, instead of agronomists, you're sure to be misled. Author Eleanor McCrary @ellie_mccrary apparently started from a 2018 disinformation piece by freelance journalist Annie Sneed @aisneed.

The Sneed article is entitled "Ask the Experts…" and the McCrary article is entitled "…Experts Say." Yet both of those journalists are so clueless about their topic that neither of them even knew who the "experts" were to ask! For their articles about agronomy, neither author spoke to a single agronomist!!

Image
2/5. The result is that both articles are full of false information.

My hypothes⋅is annotation of the Sneed article has a detailed, point-by-point critique of the major mistakes in it:

3/5. Agronomists have conducted THOUSANDS of rigorous studies, measuring the benefits of elevated CO2 (eCO2) for crops. All major crops benefit from eCO2, most of them dramatically.

It's long-settled science. In fact, the benefits of eCO2 for crops have been known to science for >100 yrs.sealevel.info/learnmore.html…
@Jeppespip @MatthewWielicki @ProfMarkMaslin @COP28_UAE @ellie_mccrary @aisneed 4/5. There is no downside to eCO2 for agriculture. None whatsoever. It is entirely beneficial.
5/5. If you think CO2 emissions and rising CO2 levels are harmful, you've been deceived. They are clearly beneficial.

To understand #ClimateChange (or any other politicized or contentious topic), you need balanced information. I'm here to help:

1/3》 No reefs are dying due to climate change. Climate Industry agitprop CLAIMS coral reefs WILL die due to climate change. But they stubbornly refuse to comply.

A web search finds lots of Climate Industry propagandists frantically "spinning" that news:
google.com/search?q=recor…
2/3》 There are coral reefs which have been damaged by storms, starfish, water pollutants, dragging anchors, dredging, silt, etc. But not climate change.

With an El Niño coming on, the Pacific will probably "slosh east," lowering water levels at the GBR. So there'll probably be more frequent bleaching events there, pretty soon. But that's normal.
3/3》 In other words, as you can see for yourself, the sources you've been trusting on the topic of climate change lied to you.

But the takeaway point is less about climate than about epistemology. This is the important lesson:

1/10. That Grauniad article is disinformation. I'll see you their "11,000 scientists" and raise you over 30,000 scientists who know better.

The best scientific evidence shows that manmade climate change is modest & benign, and CO2 emissions are beneficial, not harmful. Over 30,000 American scientists signed a petition attesting to those facts. I'm one of them.quora.com/Did-30-000-sci…

2/10. Climate change does not threaten coral reefs. In fact, most coral thrive best in the warmest water. Even the very warm southern Red Sea is dotted with healthy coral reefs (unlike the cooler Mediterranean).

If you look at a map of coral reef locations, you'll see that they're clustered around the equator.

Image
3/10. Some coral inhabit temperate zones, but most prefer tropics. In fact, where there are seasons, corals grow fastest in summer.

At 7:20 in this BBC video you can hear how wonderfully healthy the coral are in warmest part of the very warm southern Red Sea, off Eritrea.

@tobiaszowi @ProfMarkMaslin @COP28_UAE 1/11. India! That's your example? Are you joking??

Fact: Everyone, everywhere benefits from rising CO2 levels, but the Indian subcontinent benefits much more than most.

These photos were both taken in the eastern / southeastern Indian subcontinent.
sealevel.info/learnmore.html…
2/11. Fact: Rising CO2 levels have substantially boosted global crop yields, and improved crops' drought resilience.

The Indian subcontinent used to be plagued by periodic catastrophic famines. Now, despite greatly increased population, they have food surpluses every year. Rising CO2 levels are a major reason why.sealevel.info/negative_socia…
3/11. Fact: rising CO2 levels are helping to make famines rare, for the first time in human history. Few places on earth have benefited more than the Indian subcontinent.




When I was a child, horrific famines were often in the news, in places like Africa and the Indian subcontinent. But Bangladesh and India now have food surpluses, every year. Rising CO2 level is one of the major reasons.sealevel.info/learnmore.html…

1/6. I agree that that air pollution probably masked the warming effect of GHGs during the 1940s-1970s cooling period. But "measured warming" often uses baselines starting in 1979, because that's the start of satellite-based temperature measurements.


The correlation between temperatures and aerosol/particulate air pollution abatement is not perfect, but it is noticeable.woodfortrees.org/plot/uah6/mean…
2/6. The problem is that aerosol/particulate pollution abatement also dates from the 1970s. CO2's forcing has rising monotonically since ≈1945, yet temperatures only started rising (in fits & starts) with the advent of air pollution abatement in the West.


The 1979 baseline temperature, against which warming is compared, was artificially depressed due to aerosol/particulate air pollution. That means subsequent warming due to GHGs is exaggerated.agupubs.onlinelibrary.wiley.com/doi/full/10.10…
3/6. By the 1990s, the West had made great strides cleaning up aerosol/particulate air pollution, but it was worsening in rapidly industrializing Asia — and (once the super El Nino subsided) we had "The Pause" in global warming.


Santer et al attempted to compensate for ENSO and volcanoes:

1/10. You obviously didn't read any of the studies I showed you. None of your claims are true.

Humans have killed off many species, but not even one  has been driven to extinction by manmade climate change. (Not even the Bramble Cay mosaic-tailed rat.)
theatlantic.com/science/archiv…
@RealCryoraptor @twit4thot @RARohde @BerkeleyEarth 2/10. Please peruse the resources I showed you:
3/10. The climate industry propagandists who told you that "we're in a mass extinction" demonstrably lied to you. Do you even care?

That Madras photo on the right, taken when CO2 levels averaged <300 ppmv, is the "net zero" goal. Is that what you want?

If you want to learn about the science of climatology, instead of industry propaganda and political spin, here are some resources which can help you:

1/7. That's a funny!

I guess you're unfamiliar with the term "climate optimum." Here's a literature search:


Here's a 1974 CIA study about the threat of global cooling:


This graph from that study shows how cooling temperatures threaten food supplies:

@RealCryoraptor @BerkeleyEarth @hausfath @RARohde @JudithSissener @eamuller --

2/7. The modest benefits of milder temperatures are in addition to the very large direct benefits of rising CO2 levels from "CO2 fertilization," and because elevated CO2 improves water use efficiency and drought resilience in plants.
sealevel.info/learnmore.html…
@RealCryoraptor @BerkeleyEarth @hausfath @RARohde @JudithSissener @eamuller 3/7. Those beneficial effects are helping to make catastrophic famines a distant memory, for the first time in history.
