This is How Plants Predict Climate Change
Which Countries Will Be Underwater Due to Climate Change?
A new study from the Department of Energy's Pacific Northwest National Laboratory (PNNL) indicates that not only is the planet's climate shifting, but the temperature is also rising at a faster rate than ever before. Per decade, we can expect the average rate of change to be .2 to .6 degrees Celsius.
The PNNL was able to make this conclusion after looking at vast amounts of recorded temperature data. Led by researcher Steve Smith, the group examined over two dozen climate models, looking at 40-year periods of temperature change. They broke the data into these periods as a way of accounting for any kind of manmade impact on climate trends. The models they used matched historically recorded weather data and the team also used them to make future predictions. Smith told Weather.com, "[W]e're in a regime where essentially in North America and Europe and Asia, you don't see any instances where temperatures decrease. It's all increasing. We've completely shifted out of that range."

A 'megadrought' will grip U.S. in the coming decades, NASA researchers say (The Washington Post)
"The long and severe drought in the U.S. Southwest pales in comparison with what's coming: a 'megadrought' that will grip that region and the central Plains later this century and probably stay there for decades, a new study says."
