The climate will swing to extremes as it tries to find a new equilibrium, in response to the warming climate. Siberian winters will be colder, heat waves extended, etc. This report says that if you are in a rainy location, expect more deluges, and if you live in a dry area, expect more droughts. Specifically, the new study found that although the 14 climate models differ when it comes to the amount of rainfall in individual locations such as cities, over larger areas, they all point to the same average picture. That is, for every single degree Fahrenheit the global average temperature climbs, heavy rainfall will increase in wet areas by 3.9 percent, while dry areas will experience a 2.6 percent increase in time periods without any rainfall.

Rain will get more extreme thanks to global warming, says NASA study | The Verge.

ArcticOcean Flowers These spiky little bunches of ice form on thin and new ice in the Arctic Ocean. But these badboys can only form under very special conditions:

1) Calm winds. We can’t have these beauties blown away can we?

2) Cold, cold air. It has to be about 20C less than the water and since seawater freezes around -2C, that means the air must be about -22C or -7.6F. BRRR.

Frost flowers form when newly formed ice sublimates, that is ice changes directly from a solid to a gas totally bypassing the liquid stage. Initially, the water vapor formed by sublimation is the same temperature as the sea ice, but gets quickly cooled by the cold air. The air is then becomes supersaturated with water vapor, which means the air has too water much in it. Air really doesn’t want to hold all that excess water vapor, so when the supersaturated air touches another ice crystal the water vapor quickly turns back into ice. (Click the image to enlarge)
