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.

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

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.

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.

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!

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.

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.
