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.”
from Gregg Easterbrook:
Bravely, international diplomats, United Nations officials and environmentalists are meeting in Cancun this week to demand that other people use less fossil fuel. Bravely they met in Copenhagen a year ago to make the same demand, after also bravely meeting in Bali, Montreal and similar resort locales in prior years.
I will skip the obvious point about the greenhouse gases emitted by the jets and limos that bring the participants to these annual confabs, where preaching-to-the-choir is the order of the day.
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.
