The Co-Chairs of the Bicameral Task Force on Climate Change sent a letter to President Obama June 5 asking him to discuss joint action on climate issues with Chinese President Xi Jinping at the leaders’ meeting June 7 and 8. The group, which includes Representatives Henry Waxman (D-CA) and Ed Markey (D-MA) and Senators Sheldon Whitehouse (D-RI) and Ben Cardin (D-MD), urged the President to propose that China support an international proposal to reduce use of hydrofluorocarbons currently backed by the U.S., Canada, and Mexico.
