No it's not. If it were a lot, temperatures would be rising at the same rate they did between 1970 and 1990. Instead, we have a "pause".
The world production of grain is about 160 Hiroshima bombs per second. I guess that's why we're getting so fat, LOL.
WW2 lasted something like 8 years and the Nazis never controlled more than a tiny percentage of the planet. Industry has been producing CO2 from fossil fuels in fairly large quantities for about 100 years and it's world-wide. The Nazis failed quickly, fossil fuels are incredibly successful. And we're not even close to running out. Hundreds of years from now they'll still be burning vast amounts of coal.
You already lost the (propaganda) war. The Nazis had the advantage of having a well established chain of command. The greenies are all over the place. And what plays well in the newspapers are the most extreme threats and predictions. So when Oppenheimer told us in 1990 that unless we curbed our use of fossil fuels the US and Eurasia would be devastated by drought by 1995 it made a lot of news:
"[By] 1995, the greenhouse effect would be desolating the heartlands of North America and Eurasia with horrific drought, causing crop failures and food riots . . . [By 1996] The Platte River of Nebraska would be dry, while a continent-wide black blizzard of prairie topsoil will stop traffic on interstates, strip paint from houses and shut down computers," Michael Oppenheimer, published in "Dead Heat," St. Martin's Press, 1990.
Now the climate alarmists have learned their lesson and most of the dire predictions are for sufficiently far in the future that they will never have to eat their words. But humans aren't stupid. The rest of us look at the crap predictions from 20 years ago (when the big message was that "the science is settled") and since those predictions failed we don't trust the present predictions.
To get their stuff believed, the climate folks need to start making predictions that become true. This puts them in a bind. It's obviously impossible to make predictions over short time periods because no one can yet predict the weather. And if they make predictions for what is going to happen 50 or 100 years from now, then the rest of us will wait 50 or 100 years to see if their predictions are accurate. So the alarmists have shot their wad. They can no longer influence the global use of fossil fuels (not that they ever had much influence on it before) because they cried wolf. Instead, fossil fuels are cheap and their use continues to grow.
