1/18》The current slight warming trend is generally GOOD for crops, and rising CO2 levels are VERY GOOD for crops. Scientists call the periods of highest temperatures "climate optimums," because, by all objective measures, they're BETTER.
scholar.google.com/scholar?as_sdt…Image
2/18》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.

3/18》 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 our lifetimes. Do you understand how miniscule that is?
4/18》 1°C is the outdoor air temperature change ("climate change") you get from an elevation change of only about 500 feet. 🥱

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

That's 2.8× the 0.36°C "limit" which the Climate Lobby has arbitrarily proclaimed (which they deceptively call "1.5°" by referencing it to the late Little Ice Age, instead of now -- even though our current climate is clearly better than that of the late Little Ice Age).
5/18》 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?)

6/18》 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. Image
7/18》 In the American Midwest, farmers can fully compensate for 1°C of climate change by adjusting planting dates by about six days.
sealevel.info/wichita_spring…Image
8/18》 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.

9/18》 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…
10/18》 There's no downside to rising CO2 levels. CO2 levels are believed to have been well above the current 421 ppmv for >98% of Earth's history, without causing "runaway" warming, acidic oceans, or any other catastrophe.
11/18》 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.

12/18》 None of the supposed major harms predicted to result from manmade climate change are actually happening.
sealevel.info/learnmore.html…
13/18》 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!
sealevel.info/learnmore.html…Image
14/18》 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.

The rising CO2 level is one of the major reasons.

sealevel.info/learnmore.html…
15/18》 Here's what manmade climate changes is 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…"

sealevel.info/Owen2009_Sahar…
sealevel.info/090731-green-s…Image
16/18》 Here's another article about it:

sealevel.info/Pearce2002_Afr…
17/18》 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's population.
18/18》 To understand politicized issues like climate change, you need balanced info. If you think CO2 emissions are harmful, that means you aren't getting it. But I'm here to help.

1/6> annmclan wrote, "but the oceans are already too hot for coral reefs🪸"

You've been lied to, Ann.

Most coral thrive best in the warmest water. If you look at a map of coral reef locations, you'll see that they're clustered around the equator:
sealevel.info/coralreefmap.j…Image
2/6> Even the very warm southern Red Sea is dotted with healthy coral reefs (unlike the cooler Mediterranean). Why do you think that is?

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

In fact, where there are seasons, corals are commonly dated like trees, by "coring" them, and examining the growth rings. The thick rings represent summers, because that's when the coral grows fastest.

The temperature indexes are inconsistent, but you can't tell that from Priscian's misleading graph.

An honest graph would offset the traces so you can tell them apart, or else start them at the same temp. Instead he aligned the full-period averages, to hide the spread.

Here's what he's hiding:



What Jim Java / Priscian doesn't want you to notice is that the GISS (and Berkeley Earth, etc.) surface temperature indexes show much more warming than the UAH and NOAA STAR satellite-based lower troposphere measurements.

Land "surface" measurements are air temperatures measured with thermometers in Stevenson screens, usually 1.25 to 2 meters above ground. Satellite "lower troposphere" indexes (UAH, NOAA STAR, RSS) are from higher altitudes. Due to "lapse rate feedback," the (higher) altitudes where satellites measure temperatures should  see a slightly greater  warming trend than is seen 1.25 to 2 meters above the surface. Instead, they see less.


That's good cause to suspect that the surface temperature indexes from GISS etc. overstate warming.woodfortrees.org/plot/gistemp/f…
sealevel.info/GISS_vs_UAH_an…
sealevel.info/feedbacks.html…Image
2/8》
Do the math: 0.92 / 0.59 = 1.56

So, UAH6 & NOAA STAR satellite-based measurements suggest that those high-end surface temperature indexes are reporting at least 56% too much warming.

But even if it is exaggerated, the warming isn't worrisome. After all, humans are a tropical species, and most of the Earth is much too cold.


Warming saves lives, and excess cold causes many times more human deaths than excess heat — even in tropical counties, believe it or not! Here are some recent papers about it:

1. Masselot et al (2023).


2. Gasparrini et al (2022).

Composite of two figures from the paper:


3. Zhao et al (2021).

Discussion:

Summary:


4. Gasparrini et al (2015).

Fig. 2:


Are you familiar with the term "climate optimum?" If you go to ResearchGate or Google Scholar, and search for "Climate Optimum" (or Eemian Optimum, Mid-Holocene Optimum, Roman Optimum, or Medieval Optimum), you'll find thousands of papers using that terminology. Those "optimums" were warm periods.


The reason so many academic papers call the warmest periods in history "climate optimums" is that there is a consensus among historians and scientists that those warm "climate optimums" — including periods warmer than now — were, by all objective measures, better than colder periods.

Or, look at the flip side: cold periods, like the Dark Ages Cold Period (DACP) and the Little Ice Age (LIA). There's a broad consensus that those cold periods were, by all objective measures, worse for humanity than the warm "optimums."


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


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

Depending on whose temperature index you use, we’ve seen an average of between 0.59 and 0.92 °C of warming since 1958 (when Mauna Loa CO2 measurements began).



That warming has shifted growing zones and “temperature isotherms” slightly toward the poles (northward, in the NH). So, the obvious question is, how far?

That’s easy to answer, by looking at an agricultural growing zone map. Here's one, shared by permission from the Arbor Day Foundation:


From eyeballing the map, you can see that 1°C (1.8°F) = about 50-70 miles latitude change.

Here's James Hansen and his GISS colleagues reporting a similar figure:

Excerpt: "A warming of 0.5°C... implies typically a poleward shift of isotherms by 50 to 75 km..."

That's 100 to 150 km = 62 to 93 miles per 1°C. So, the 0.59 to 0.92 °C of warming which we've seen has caused, on average, a growing zone shift of only about 30 to 86 miles). Ho hum.🥱woodfortrees.org/plot/gistemp/f…

1/3. MunichRe is not just an insurance company. It's the giant German reinsurance company which bankrolls Rahmstorf and Potsdam Institute (PIK). They're among the worst and most extreme promoters of crackpot climate alarmism, just short of XR.

2/3. Hyping climate alarmism is a business strategy for MunichRe, because they realized climate alarmism is good for their business. When people expect worsening disasters, they're willing to pay more for reinsurance.


They're using a updated version of the old "FUD" marketing strategy.

3/3. Do you know where the "extreme weather" nonsense came from? Not from evidence, but from James Hansen's epic confusion.

Somehow he avoided learning about Arctic Amplification. He thought AGW would warm the tropics MORE than high latitudes.


That's a clip of Hansen on Letterman, explaining it. Hansen claimed that the “increasing temperature gradient” [between high & low latitudes] would "drive stronger storms.”

That's just plain wrong. The temperature gradient is DECREASING, not increasing.

You see, "global warming" isn't really very global. Thanks to stronger-than-linear negative feedbacks, such as Planck cooling, warm climates are more stable than cold climates. So AGW disproportionately warms chilly high latitudes. The tropics are affected much less (which is nice, because the tropics are warm enough already).


Hansen wrote a ridiculous book based on his confusion, and did a whirlwind publicity tour, pitching the book & spreading the claim that AGW will cause worsening storms / weather. (That's why he was on Letterman.)


Nearly all climate scientists know that's wrong, but none of them challenged him. Nearly everyone in the climate biz (maybe even Hansen, by now), has heard of Arctic Amplification, but the climate industry is so corrupt that neither Hansen's colleagues nor anyone else in the industry corrected his error.

1/18.
Zoya Teirstein @zteirstein, please stop spreading climate disinformation. Climate propaganda is killing people. Do you care?

There are NO "climate sensitive diseases." That's unscientific marketing FUD, from the parasitic climate industry.

2/18.
Lyme disease was first identified in chilly Lyme, CT. Rocky Mountain Spotted Fever was first found in frigid Idaho & Montana. Both spread SOUTH — obviously NOT due to global WARMING.
Like every other climate scare, this one is a lie.


There's no evidence at all that climate change is spreading ticks and the diseases they carry, or any other disease. One degree of warming is equivalent to just 50-70 miles latitude change — completely trivial compared to tick ranges.
@zteirstein 3/18.

1/5》 Do the math, Martin!

WMO estimates a total of 1.15 ±0.13°C of warming since "preindustrial" (late LIA).

At most  80% of human GHG forcing was from CO2, so even if ALL  the warming was from GHG emissions, 1.15°C means at most 0.92°C was from CO2.


Here's the WMO reference:


NCA4 gives a similar figure (1.14 ±0.13°C).

(Aside: those confidence intervals are, IMO, overly confident.)

Here are estimates for the percentage of warming due to CO2.

AR6:


NOAA's AGGI (compare heights at the right edge):


Myhre 1998:


AMS (compare the numbers in the "Rad. Forcing" column):


Kiehl & Trenberth 1997:
google.com/search?q=1.15+…
2/5》 If we got at most  0.92°C of warming from 58% of the forcing of a full doubling of CO2, then (at most) how much warming we could get from a full doubling of CO2?

Ask google:
google.com/search?q=0.92+…
3/5》 Those figures are very conventional estimates, widely accepted by climate alarmists. Yet those same climate alarmists believe that TCR climate sensitivity is 1.5 to 2.0°C/doubling of CO2, and ECS is about 3.0°C/doubling of CO2.

1/10. Where on earth do you "learn" such nonsense, Willard?

Growing ranges for most major crops cover climate zones with average temperatures that vary by tens of °C. Major crops like corn, wheat, potatoes & soybeans are produced from Mexico to Canada.

Compared to that, a degree or two of warming (disproportionately at night, in winter, at chilly high latitudes) is de minimis -- as is the 0.35±0.13°C between now and what the IPCC calls "1.5°C of warming").
Image
2/10. Willard wrote, "fertilization is the male gamete to female gamete to produce seed/fruit... not the N-P-K addition"

Wrong. In agriculture, that's called pollination.
3/10. Willard wrote, "(yes, it is often temperature sensitive)"

Wrong. Farmers choose planting dates to optimize growing conditions, including temperatures, for their crops.
