When they're right, they're right. Global Warming is a yuge problem and could become waaay more expensive than any countermeasure.

Global Warming is bunk.  Every prediction predicted to date has been wrong.  That track record is unlikely to change.  So-called climate models are about as effective at modeling the climate as Gosplan (https://en.wikipedia.org/wiki/Gosplan) models were at modeling an economy.

Mathematical modeling is always flawed. Models vary in results depending on the levels of greenhouse gas emissions. That is the unpredictable amount. Add more carbon dioxide, halocarbons, and sulfur hexafluoride  to the atmosphere, and more water vapor goes into the air. Water vapor is the most effective greenhouse gas, more powerful than carbon dioxide, but higher temperatures over the seas put more water vapor into the air because higher temperatures mean that more water can be held in the air. 

If you have ever noticed, the measurements of the shares of gases in the atmosphere are shown for those that do not vary by location  -- nitrogen, oxygen, argon, etc. Water vapor and carbon dioxide are not listed because those vary significantly. The air is much more 'juiced' in Kuwait than in Marseilles, let alone in polar regions. Oh, so why is Kuwait a desert if the air is so juiced? The cold fronts that bring drenching rain to  reach Marseilles in the winter, but cold fronts reach only about as far south as Tunis, Tehran and Tel Aviv in the winter.  

The models differ based on the amount of greenhouse gases that Humanity recklessly and improvidentially release into the atmosphere. Greenhouse emissions are the variable in the model. How the atmosphere acts with different levels of greenhouse gases is not so controversial.

 in 2100:



There will be longer growing seasons -- but less water available. The C-D border between "rainy" winters and "snowy" winters goes from about Kansas City, St. Louis, and Louisville  to around Omaha, Chicago, and Detroit. Longer growing seasons will be nice in places like Fargo, North Dakota -- except that crops will need more rainfall and snow just to adjust to warmer conditions... and might be inadequate. Milder winters might expand the zone of tropical crop potential in Florida -- except that drought might intervene. California's San Joaquin Valley, one of the top crop-growing areas in America, becomes full-blown desert.   

The new Mediterranean belt along the Gulf Coast suggests that cold fronts will reach the southeastern USA only in the winter, late autumn, and early spring, but the air will still be juiced enough then for copious rainfall. There will apparently be no summer monsoon or a very slight one.  

Cactus will be part of the Los Angeles scene as they are in Phoenix. Full-blown desert starts appearing in southeastern Colorado and eastern New Mexico
