Why Increased CO2 Makes The Climate Less Extreme

Over the past century, as CO2 has increased in the atmosphere, the frequency of hot days in the US has plummeted.

The average maximum temperature has also plummeted as CO2 has increased.

Meanwhile, the average minimum temperature has increased as CO2 has increased.


The average daily temperature range has plummeted as CO2 has increased. We are seeing many fewer extremes in temperature than we did 100 years ago.

So what could be causing this?  NASA explains it below.

More CO2 causes more vegetation, which moderates both daytime and nighttime temperatures. In addition, more CO2 causes plants to need/use less water, which increases soil moisture. Soil moisture is one of the most important factors used by weather models when forecasting precipitation. Not surprisingly, precipitation has increased along with CO2.

Heatwaves are caused by dry soils, and dry soils are exacerbated by heatwaves.

The increase in CO2 is causing more vegetation, more rainfall, fewer extremes in temperature, fewer heatwaves and fewer droughts.  The exact opposite of what scientifically ignorant climate scientists claim.
