By Kate Aronoff for In These Times - BONN, GERMANY—California Gov. Jerry Brown (D) is set to have a big week here in Bonn at the UN Framework Convention on Climate Change’s 23rd Conference of the Parties (COP23). He and former New York Mayor Michael Bloomberg are key figures in the U.S. Climate Action Center (USCAC), an unofficial voice for the United States at the climate summit (the official U.S. delegation is keeping a low profile). With the Trump administration intending to withdraw from the Paris Agreement, the USCAC’s rallying cry is fairly clear: We Are Still In. A few minutes into a Saturday USCAC event featuring Wal-Mart’s Senior Vice President of Sustainability, Brown was interrupted by protestors asking, “Still In For Want?” A group of Californians and other delegates to COP23 from the United States—many involved in climate justice organizations—stood up as Brown started speaking, giving short testimonies about Brown’s close relationship to the fossil fuel industry, a major force in California’s economy. After protesters chanted “Keep It In The Ground,” in opposition to fossil fuel extraction, Brown replied, “Let’s put you in the ground so we can get on with the show here.” Clumps of interrupters continued to pop up and be escorted out through the rest of the presentation, prompting responses from Brown. “Unfortunately, in politics,” he said, “we don’t have a magic wand. … I can’t say ‘Stop, there’s no more coal, no more oil.’ ”
