“An Inconvenient Sequel” delves deeper into the arcane details of compromise than its predecessor, with scenes of Mr. Gore working to find a middle ground between the needs of developed and developing nations. In a group meeting, Piyush Goyal, India’s power minister, pushes back against Mr. Gore’s desire to replicate in India the expanded use of solar energy in the United States. “I’ll do the same thing after 150 years,” Mr. Goyal replies.
During the 2015 Paris Climate Change Conference, Mr. Gore, who wasn’t an official negotiator, tries to persuade Lyndon Rive, then chief executive of the American company Solar City, to grant India the rights to a patent on a type of solar technology. (The results aren’t clear from the film; India signed on to the Paris agreement without making a deal with SolarCity and still hasn’t made one.)
Mr. Gore likens President Trump’s election to a quip often attributed to Mike Tyson: You always have a plan until you get punched in the face. The movie has been updated since its premiere at the Sundance Film Festival in January to include Mr. Trump’s announcement of the United States’ withdrawal from the Paris climate accord, a decision that probably forecasts another sequel.
