Global environmental challenges
Google unveiled a powerful new mapping tool at the Cancun climate talks on Thursday that allows scientists to monitor changes in the Earth’s environment as climate change accelerates.
The search giant’s philanthropic arm, Google.org, calls the new Google Earth Engine “a planetary-scale platform for environmental data and analysis.” It combines Google Earth’s maps with 25 years’ worth of Landsat satellite images and other data.
Just as important as that data goldmine is Google’s move to put its immense computing resources at scientists’ disposal. Google.org is donating 20 million computational hours over the next two years to developing countries so they can monitor their forests as the United Nation’s prepares to implement an initiative called REDD, Reducing Emissions from Deforestation and Forest Degradation in Developing Countries.
“Deforestation releases a significant amount of carbon into the atmosphere, accounting for 12-18 percent of annual greenhouse gas emissions,” Rebecca Moore, the engineering manager for Google Earth Engine, wrote in a blog post. “For the least developed nations, Google Earth Engine will provide critical access to terabytes of data, a growing set of analytical tools and our high-performance processing capabilities. We believe Google Earth Engine will bring transparency and more certainty to global efforts to stop deforestation.”
It took just 30 seconds to fell the tree. Hendri, 27, a skinny Indonesian from Central Kalimantan on Borneo island, skilfully wielded the chainsaw more than half his height. The result is a thunderous crash and a tree that is quickly cut into planks on the forest floor near by.
It sounds almost too good to be true: new technology that would be better than carbon neutral — it would be carbon negative, taking more climate-warming carbon dioxide out of the air than factories and vehicles put in. It’s called air capture technology, and Reuters took a look at some promising versions of it on October 1.
This technology is expected to help some of the world’s poorest countries capitalize on any global carbon market, which would put a price on carbon emissions and let rich companies that spew lots of carbon buy carbon credits from poor companies and countries that emit less. The least developed countries emit very little carbon now. But the way the carbon market is set up under the Kyoto Protocol, this puts them at a disadvantage. If you don’t emit a lot it’s tough to get access to financing and clean technology under the current rules.
