When a TV meteorologist says "temperatures will be ten degrees above normal", the word "normal" has a specific meaning. Every 10 years NOAA re-calculates the "normal" temps for the USA based on the prior 30-year averages. The new normals have just been released, based on the 30 year period 1980-2010. Hotter is the new normal. With hotter weather comes more extreme weather. Extreme Weather and Climate Change, 3-part series from Scientific America .. and map of extreme weather events 1995-present.

We've discussed the "once in a century" Amazon Drought of 2005-06. Five years later and we are seeing another once in a century drought in the Amazon. How serious are the effects of these droughts for global climate? The science appears to be mixed. Helping monitor is the newly released Google Earth 6.0, which can track individual trees within a section of the Amazonian forest, and 80 million other trees in 7 cities around the world (video).

So you've all heard about how global warming will lead to rising sea-levels, but what about falling freshwater levels? [more inside]

Georgia's going dry -- and we're not talking liquor stores. Record temperatures in Georgia and a long drought have left many Georgia cities wondering when the taps will run dry. Some towns have only a few weeks of water left, while rivers near Athens have nearly dried up. A broken water main hasn't helped the problem, and some fear that the University of Georgia campus there may shut down for lack of water. What's more, Atlanta itself is already feeling the pressure, as Lake Lanier, a water source for 3 million residents, falls by 1.5 feet per week and has only a three month supply remaining. While there have been more severe (pdf) droughts in Georgia's history, rising population numbers have increased demand to now unsustainable levels.

Global warming approaching point of no return...
Climate change: report warns point of no return may be reached in 10 years, leading to droughts, agricultural failure and water shortages. The possibilities include reaching climatic tipping points leading, for example, to the loss of the West Antarctic and Greenland ice sheets (which, between them, could raise sea level more than 10 metres over the space of a few centuries), the shutdown of the thermohaline ocean circulation (and, with it, the Gulf Stream), and the transformation of the planet's forests and soils from a net sink of carbon to a net source of carbon. Countdown to global catastrophe
