Despite the severe storms now raging across the country, the long term future will be a drier one. The long lull in sunspot activity at the end of the last 11-year solar cycle gave us more time to work on solving the climate change problem, but a new analysis of the magnitude of climate change during Earth’s deep past suggests that future temperatures may eventually rise far more than projected if society continues its pace of emitting greenhouse gases.read more

We don’t have to worry about inhaling radiation from Japan, but as carbon dioxide levels have risen during the last 150 years, the density of pores that allow plants to breathe has dwindled by 34%, restricting the amount of water vapor the plants release to the atmosphere–a situation that will lead to drought. And WE may not be breathing well either if we don’t do something about the dying plankton in our oceans!

A new, detailed record of rainfall fluctuations in ancient Mexico that spans more than 12 centuries will help us understand the role drought played in the rise and fall of pre-Hispanic civilizations. If there’s a drought in OUR future, we’d better learn how to make it rain. The Middle Eastern country of Abu Dhabi is doing just that, causing 50 rain storms in the desert during that past year.

How can a part of the world transform from a green area into a desert? It happened to the Sahara and scientists think this was due to a change in the tilt of the earth. Changes in the Earth’s tilt happen from time to time and they change the weather. A change in our orbit could have done the same thing, and scientists say the earth’s orbit continues to change and will continue to do so in the future.
