What trend has been noticed over the last several decades in terms of atmospheric moisture content? Why does this trend exist?. Geography

Significantly more moisture in the atmosphere; long-term buildup of greenhouse gases in the atmosphere is

trapping heat and warming up the land, oceans, and atmosphere. Notably the Arctic, are warming faster than

others. As the oceans warm, they’re giving off more water vapor – past 25 years have measured 4 % average rise.

More water vapor, the greater the potential for intense rainfalls.
