Carbon Dioxide Levels Reach Record Level in March
The last time carbon dioxide levels were this high was a million years ago. The global community needs to reduce emissions by 80 percent to stop the increase in CO2 levels. The data was reported by the National Oceanic and Atmospheric Administration.
New Methane Emission Regulations Aim for 45 Percent Reduction by 2025
President Barack Obama hopes to add to his "climate legacy" by having the EPA adopt the nation's first regulations to reduce methane emissions, the second most prevalent greenhouse gas emission after carbon dioxide, but far more powerful.
Nebraska Supreme Court OKs Keystone XL; U.S. Senate has the Next Move
