Can a desert tree fight global warming?

Scientists at Tel Aviv University say they have a novel idea for combating the negative effects rainforest deforestation is having on the planet.

The group, led by Amram Eshel and Aviah Zilberstein, professors at TAU's Department of Molecular Biology and Ecology of Plants, have successfully grown a forest of salt cedars in the Aravah Desert using only a small amount of recycled sewage water and salt water left over from desalination plants.

The scientists used different varieties of the botanical genus of salt cedar trees called Tamarix, which is indigenous to old-world deserts. They're known for thriving in … Read more

Tracking deforestation in real time

Google.org, Google's philanthropic arm, has announced a cloud-based method for analyzing deforestation around the world, in a much more up-to-date manner than was previously possible.

Using Google's terabytes of satellite imagery, it allows scientists to look back over time at any location in the world to see how the forest has changed. Going beyond visual comparisons, it uses the power of cloud computing to do actual measurement of deforestation. Much more rapid analysis of the images than is possible on a single desktop computer pinpoints locations of most recent activity. This allows authorities to locate illegal logging … Read more

Google.org unveils deforestation monitor

Google.org demonstrated a new platform on Thursday that, if implemented in conjunction with a proposed United Nations program, could provide a significant tool to combat climate change.

Its new "high-performance satellite imagery-processing engine" can process terabytes of information on thousands of Google servers while giving access to the results online.

The platform, which was demonstrated on Thursday at the International Climate Change Conference in Copenhagen, would allow anyone using the tool to monitor whether or not trees were being chopped down in a given forest. It analyzes satellite images to show forest changes over a given time … Read more
