Rep. Henry Waxman (D-Calif.), a top House Democrat, is urging the Energy and Commerce Committee’s Republican majority to hold a hearing that explores links between climate change and extreme weather.

The request, spelled out in a letter Friday, is a sign that Democrats and environmentalists hope to translate the recent record-setting heatwaves into political momentum for efforts to battle global warming.

It asks Committee Chairman Fred Upton (R-Mich.) to convene a hearing “on the recent wildfires and extreme weather events the United States has experienced and the role global climate change played in these events.”
