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.

    CO2 Rocks and you do too.

    Tony

    I read your website plus iceagenow.info and climate depot.

    I also read drtimhall who is a retired climatologist from Winnepeg University in
    Manatoba Canada.

    You are all exposing the Global Warming/Climatechange Cult.

    My Very Best Regards to you.

    So simple and so logical.

    But making the world a better place is not in the progressive’s interest. They want (and need) chaos and misery.

    Spot on!
    Extending on this equals milder winters and longer growth season. What is the problem?

  5. feathers says:

    And no difference in average global temps?

    Every idiot knows that we did not have the capacity to measure temperatures accurately until 1979. Before 1979 we were allowing moronic, drunken farmers with Stone Age thermometers determine temperatures. Now temperatures are determined by highly brainwashed climate scientists, all with PhD’s from leading schools like Pedophile State in Pennsylvania. They know exactly what the temperature is, and know precisely what the temperature will be in the future, based on their highly sophisticated climate models. Every month will be the hottest on record, every year will be the hottest on record. That you can bank on. They don’t need any damned thermometers. Thermometers are so 20th Century!

    • JPinBalt says:

      I bet the the thermometer is close to Mann’s office at Penn State, that or back seat of football coach’s car, but that does not matter since can use hand picked tree ring reconstructions, or Galvin at GISS can just create data out of thin air. You are right, who needs thermometers when we have priest experts and IPCC which can tell the future?

      But I would not be calling Hadley and Newton “moronic, drunken farmers” checking and recording temperature, even Dalton if alive today would agree that rise in temps by their “Stone Age thermometers” for CET in UK going back to 1659 would show that the rise in temperature from 1700 to 1740 is clearly double what alarmists now call catastrophic for 1980 to 2000 for hall of fame and old meteorologists.

      And Newton bought South Sea stock, as any “idiot” can buy bitcoin today. Old temperature records are yes only a proxy, or maybe bitcoin is proxy for newer measurements since all that digital coin mining consumes massive amounts of energy and CPUs get very hot. Personally I like ice core isotope proxies for record estimation, but that is not global.

    Increased albedo reflects away more irradiation. Less heat in means cool down.

    Damn-this air pollutant is really really evil.
    lifethreatening and apocalyptic

    at least for those guys who want to abort babies at any stadium and as many as possible and without real reasons
    while defending the lifes of massmurderers and protesting against death penalty.

    (i guess we can see a pattern here)

    Australia used to be completely forested; perhaps it will be thus once again?

    Tony,
    The graph of the fall in the diurnal temperature range (Average Daily Temperature Range US HCN) is interesting, but have to say/speculate it is likely mostly Urban Heat Island effect around all the city thermometers by low surface ozone plus nighttime building heat escaping, car exhaust, etc., trapping heat like a bubble over the buildings which have grown over the last century with urbanization. It is always warmer in the city at night than the suburbs or rural areas not to far away, day and night, and some of that city smog also shields sunlight from getting through in day outside trapping heat at night.

    Would not mind seeing the same diurnal graphs splitting US HCN into urban and rural stations, (but there is no doubt by satellite data the world has been getting much greener due to CO2 and increased photosynthesis, and if were had CO2 fall by 100 ppm to 200 ppm instead of rise, that would be a true catastrophe of epic proportions causing billions of deaths as a major fraction of the earth’s vegetation [1/3?] would suffocate at lower CO2 levels, would be human starvation on scale never seen before, even beyond Hollywood’s wildest imagination, and at 0 ppm no life would exist on this planet).

    Well then, your homogenization skills are lacking. Get back to work young man.

    I recently read a paper that linked increased agricultural production to higher levels of rainfall and decreased heat waves in the Midwest. And I understand how increased vegetation can do that. However, not only are summers are milder, but winters also are milder. What is the connection between increased CO2/increased vegetation and higher winter temperatures?

    • gator69 says:

      Higher winter temperatures are the result of UHI.

    • Richard M says:

      Tony only hit on one of 3 reasons. UHI was also mentioned above. The 3rd reason is also why winters are getting warmer.

      The reason CO2 doesn’t warm as much as alarmists would like has to do with convection. Increases in DWLWIR will lead to corresponding increases in evaporation and convection. This is a negative feedback. However, it is strongest during the day and weaker at night. Hence, we get a little more warming at night and because winters have longer nights, more also in the winter.

    Excellent post, thank you! Yes, when you look at the options (1. turning Arizona & New Mexico into 10″-deep algae ponds with mechanical paddlewheels, 2. building several Germany-sized solar plants in North Africa, 3. dedicating 1/2 of the arable land in the U.S. Midwest to biofuels plant production, interspersed with 10’s of thousands of wind turbines, etc) it makes the most sense to just plant more trees (and other green things) and keep burning coal, oil and gas.

  14. Ron Van Wegen says:

    Humorous error!

    Quote: “Heatwaves are caused by dry soils, and dry soils are exasperated by heatwaves.”

    Should be: Heatwaves are caused by dry soils, and dry soils are *exacerbated* by heatwaves.

  15. JPinBalt says:

    Tony,
    Thank you for your postings, but a graph request for a repertoire of your good work to see the same diurnal temperature range (Average Daily Temperature Range US HCN) graphs you posted, but split into TWO graphs for urban and rural US HCN stations. I am curious if UHI impacts, and suspect the fall in diurnal temperature range is greater for high population growth urban areas than rural areas.

    If you could post here the two split range graphs (or better even six for Min/Max/Range and slopes for the least squares trend line estimates), most appreciated, or could owe you a lager beer next time in Laurel or Bmore, or better an ale served at warmer temperatures since less saturated CO2 (like oceans which cover 71% of planet surface containing 93% of CO2 causing out gassing when our sun’s cycles warms the earth, temp ↑ ⇒ CO2 ↑ , and not CO2 ↑ ⇒ temp ↑ as was said in Inconvenient Lie).
