Politics of Climate Change Got More Complicated in 2019 Jamie Dettmer 2019 was the year of Greta Thunberg, Extinction Rebellion and an uptick in climate action pledges by governments across the globe. From Britain to Germany, Europe's mainstream party leaders scrambled to respond to a surge in electoral support for Green parties -- and to growing public anxiety about the possible impact of climate change. During European Parliament elections in June, 48 percent of voters identified climate change as their top worry. Opinion polls in Germany for some weeks of 2019 put the Greens ahead of Chancellor Angela Merkel's storied Christian Democratic Party, which, along with its junior partner in the country's governing coalition,has been racing to sharpen climate policies. British move In Britain, the ruling Conservatives announced a hugely ambitious carbon reduction plan, enshrining into law a pledge to reach net-zero carbon emissions by 2050, making Britain the first major economy to do so. Some smaller countries, including Finland and Norway, are earmarking dates earlier than 2050 to become net-zero greenhouse gas producers, but so far have not made their goals legally binding. In America, an alliance of 24 states and Puerto Rico promised to uphold the goals of the Paris Agreement on climate action, despite the Trump administration's withdrawal from the international pact. Shouldn't all these plans and pledges be music to ears of climate action activists and scientists? .
