If carbon dioxide emissions suddenly stopped, the planet would cool for the first century due to ocean uptake, and then temperatures would rise for the next 400 years as the seas took up less and less heat, according to a recent study in Nature Climate Change. Using climate models, the authors also found that it will take much less carbon than previously estimated to reach the 2-degree C point many scientists believe will dangerously interfere with the climate system.

Landsat Satellite Imagery Highly Valuable to UsersDecember 4, 2013 - 2pm
Stakeholders in many different sectors, application areas, and project locations and scales use Landsat satellite imagery available at no cost through the USGS, according to results of a new survey conducted by social scientists at the USGS Fort Collins Science Center. Based on responses from more than 11,000 users, the researchers were able to determine who uses the imagery and for what purposes.
USDA, EPA Partner to Support Water Quality TradingDecember 4, 2013 - 2pm
The USDA and the EPA are partnering to expand support for water quality trading and “other market-based approaches” that provide environmental and economic benefits such as carbon capture and storage, air quality improvements, and enhanced wildlife habitat. Using cost savings and other economic incentives as motivators, parties would be able “to purchase and use pollutant reduction credits generated by other sources in a watershed.”
