Yes, that’s so true. And it may sound weird, but when one understands the science behind it the mysteries get solved.
There are increasingly more droughts AND more deluges of biblical proportions. (and plagues) And that is because warming air holds more water vapor – sucking it out of water bodies, soil, and plants – desiccating them, leading to greater wildfire risk. Then under certain weather conditions that water up there can come down as a extreme precipitation event (blizzard, deluge), flooding out places. Add to that greater snowfall, then greater and earlier spring melt, and Upper Midwest, you’ve got problems. And in drought-stricken places where the plants have died back or been wiped out by wildfires, that could lead to severe mudslides when that all water up there comes down as a severe deluge.
These are all noted to be on the increase globally:

The most recent tragedy in Uttarakhand, India:

Here is part of the reason: more heat and water in the atmosphere, the greater potential for that to be turned into kinetic enegry in the form of fiercer storms and hurricanes.
Also in order for a hurricane to even form, the sea-surface temps need to be high…which is why you usually don’t get hurricanes hitting California – due to the cold Humbolt current – unless they come up thru the hot Sea of Cortez.
This is a necessary, but not sufficient cause, since there are other factors (e.g., re wind sheer, etc) that need to come into play, so it has been difficult to say whether there will be more frequent storms, only that they will be more intense…until now, with Emanuel’s new study, which projects they will be more frequent, as well.
Some helpful studies and sites with info and/or links to studies:
Now this is one of the most disturbing developments for me, bec when moving to the Lower Rio Grande Valley of Texas in 2002, I was thinking the one silver lining to AGW is that we will have less killing freezes (that kill our tropical garden and winter veggie crops…since summer is too hot and dry to grow them).
Then come to find out AGW is also increasing negative Arctic oscillations, bringing cold snaps from north to south (making the Arctic warmer than usual, but killing my garden), rather than the more usual west-to-east pattern. However, studies are coming in showing that these Neg AOs are increasing due to GW factors:
The upshot is that the global average temps continue to increase, but regional weather in many areas involves wider swings than before, including really bad cold snaps that kill my garden.
One has to understand that there are many factors impacting climate, the enhancing greenhouse effect being just one. For instance the short-term fluxes in solar irradiance, and the sun having been in a deep “solar minimum” for the past 13 years… which if it were not for the enhancing GH effect would have brought the global average temp down to pre-1970s levels.
So the time-temp chart is like a saw blade, but that blade is pointed upwards.
Also it has actually continued to warm over the past 13 years, if one includes the various places on earth the heat is being stored, such as the oceans.

Hope this post helps to clarify some of the mysteries re AGW.
