"President Obama should press Chinese President Xi Jinping to curb emissions of a short-lived, but highly potent heat-trapping pollutant when the leaders meet this week in California, a group of House and Senate Democrats wrote Wednesday to Obama."

"The Democratic lawmakers said Obama should push Xi to join an effort led by the United States, Canada and Mexico to slash production and use of hydrofluorocarbons (HFCs).

“We encourage you to raise HFCs with President Xi and to ask for his support of the North American HFC proposal. This would send a powerful and concrete message about the ability of United States and China to cooperate to address the enormous challenge of climate change,” they said, noting scientists predict HFCs could account for 20 percent of global warming by 2050."
