Global warming and the risks it poses to the U.S. economy will take priority at the White House this week at two planned roundtable discussions. 

The discussions mark the one-year anniversary of President Obama's high-profile speech on climate change and his detailed plan to mitigate its effects. 

On Tuesday, Treasury Secretary Jack Lew, advisers to the president John Podesta and Valerie Jarrett, National Oceanic and Atmospheric Administration head Kathryn Sullivan and Federal Emergency Management Agency Administrator Craig Fugate will meet with insurance industry representatives regarding climate impacts.

On Wednesday, Lew and White House leaders will meet with billionaire climate activist Tom Steyer and former Treasury Secretary Henry Paulson to discuss a report released on Tuesday titled "Risky Business," which estimates how much climate change will cost businesses.

According to the report, rising sea levels, storms and hurricanes related to climate change could cause $35 billion in damage over the next 15 years, and increased flooding and droughts could wipe out up to 10 percent of farmland over the next 25 years.

Steyer, a former hedge fund manager and major donor to the Democratic Party, has promised to spend $100 million through his group NextGen Climate Action to back candidates who support climate change mitigation policy. He opposes the Keystone XL pipeline from Canada, which the Obama administration is considering for approval.

Obama will also address conservationists at an annual dinner Wednesday night for the League of Conservation Voters, a big campaign spender among environmental groups. Energy Secretary Ernest Moniz and Interior Secretary Sally Jewell are scheduled to speak Wednesday at an earlier event for the group.
