California Gov. Jerry Brown (D) on Tuesday was named a special adviser to the United Nations Climate Change Conference in Bonn, Germany, later this year.

The appointment by Fiji Prime Minister Frank Bainimarama came less than two weeks after President Trump Donald John TrumpSteele Dossier sub-source was subject of FBI counterintelligence probe Pelosi slams Trump executive order on pre-existing conditions: It 'isn't worth the paper it's signed on' Trump 'no longer angry' at Romney because of Supreme Court stance MORE announced that the U.S. would withdraw from the 195-nation Paris climate accord.

Dozens of business executives, mayors and governors including Brown have vowed to uphold the country's commitment to the agreement despite Trump's decision to withdraw.

Brown has become a high-profile advocate for climate action on the world stage in recent weeks. The California governor traveled to China last week, where he spoke with President Xi Jinping about climate change and signed bilateral climate deals.

He also hosted German Environment Minister Barbara Hendricks in San Francisco, reaffirming his state's commitment to combating the effects of climate change and abiding by the terms of the Paris deal.

When he travels to Germany for the U.N. conference — COP 23 — in November, Brown will be a special adviser for states and regions, representing local jurisdictions committed to fighting climate change.
