@MisinformNoMore @WeiZhangAtmos 1/ That's complete nonsense.

Given the constraints of limited fossil fuels, negative carbon feedbacks (which remove CO2 from the air), and logarithmically diminishing warming effect, we might eventually get as much as 1°C of additional warming from CO2. Probably less.

@MisinformNoMore @WeiZhangAtmos 2/ 1°C is the temperature change ("climate change") you get from an elevation change of about 500 feet.

@MisinformNoMore @WeiZhangAtmos 3/ At mid-latitudes, 1°C is about the temperature change you get from a latitude change of just 60 miles.

How different are the flora and fauna 60 miles from where you live?

@MisinformNoMore @WeiZhangAtmos 4/ °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.

@MisinformNoMore @WeiZhangAtmos 5/ In the American Midwest, farmers can fully compensate for 1°C of climate change by adjusting planting dates by about six days.

@MisinformNoMore @WeiZhangAtmos 6/ 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.

@MisinformNoMore @WeiZhangAtmos 7/ What's more, one of the nice things about "global warming" is that it isn't very global. It disproportionately warms frigid winter nights at chilly high latitudes. The tropics are warmed less, which is good, because they're warm enough already.

@MisinformNoMore @WeiZhangAtmos 8/ By objective standards, most of the Earth is much too cold. That's why scientists call the periods of warmest climate Climate Optimums: because they are better than colder periods.

Cold kills far more people than heat does. Here's a paper:

@MisinformNoMore @WeiZhangAtmos 9/ Note esp. this figure from the paper:

@MisinformNoMore @WeiZhangAtmos 10/ Even at low latitudes cold kills more people than heat does. But at high latitudes the disparity is enormous. This is for the UK:

@MisinformNoMore @WeiZhangAtmos 11/ Elevated CO2 levels are beneficial everywhere.
