Dominated by emissions from cars, trucks and other forms of transportation, suburbs account for about 50 percent of all household emissions – largely carbon dioxide – in the United States.
The study uses local census, weather and other data – 37 variables in total – to approximate greenhouse gas emissions resulting from the energy, transportation, food, goods and services consumed by U.S. households, so-called household carbon footprints.
A key finding of the UC Berkeley study is that suburbs account for half of all household greenhouse gas emissions, even though they account for less than half the U.S. population. The average carbon footprint of households living in the center of large, population-dense urban cities is about 50 percent below average, while households in distant suburbs are up to twice the average.
Interactive carbon footprint maps for more than 31,000 U.S. zip codes in all 50 states are available online at http://coolclimate.berkeley.edu/maps.

The UC Berkeley Graduate Certificate in Geographic Information Science and Technology (GIST) has been approved. This certificate will provide an academic structure for an interdisciplinary exchange of ideas around geospatial information and analysis.
Requirements include at least three courses, or a total of 90 hours of instruction, and earn a minimum grade of , and participate in a GIST Roundtable (such as the geolunch series from the GIF). More details to be posted in the spring at GIS@Berkeley.edu.

Have you ever wondered what are the crucial habitats and corridors for Sage Grouse, Black Bear, and other wildlife species? Seventeen westerns states have collaborated through the Western Governors’ Wildlife Council to create the Western Wildlife Crucial Habitat Assessment Tool (CHAT) for public release in December, 2013. The CHAT aims to bring greater certainty and predictability to planning efforts by establishing a common starting point for discussing the intersection of development and wildlife. CHAT will be an easily accessible online system of maps displaying crucial wildlife habitat and corridors across the West. For more information visit http://www.westgov.org/initiatives/wildlife.
This creative project from GeoWiki seeks to get croudsourced feedback on crop types from participants around the world. They say:
By 2050 we will need to feed more than 2 billion additional people on the Earth. By playing Cropland Capture, you will help us to improve basic information about where cropland is located on the Earth's surface. Using this information, we will be better equipped at tackling problems of future food security and the effects of climate change on future food supply. Get involved and contribute to a good cause! Help us to identify cropland area!
Oh yeah, and there are prizes!
Each week (starting Nov. 15th) the top three players with the highest score at the end of each week will be added to our weekly winners list. After 25 weeks, three people will be drawn randomly from this list to become our overall winners. Prizes will include an Amazon Kindle, a brand new smartphone and a tablet.
Here is another cool one: real-time map of all the flights in the air. It looks crowded!
Happy and safe travels everyone.
