Are radical climate activists hurting the cause?Germany should have been a global leader in combating climate change-its voters consider it a major issue and back the world's most powerful Green Party. Yet, Germany's climate policies have been disappointing. What happened?In Climate Radicals, Cameron Abadi profiles the fascinating activists of Letzte Generation, known for gluing themselves to street intersections and throwing food on works of art; Ende Gelande, which demands the immediate phaseout of coal by occupying mines; and the German leaders of the global coalition Fridays for Future, which organizes school strikes (on Fridays) and many other large-scale demonstrations.Abadi finds that the groups' uncompromising stances and outrage over narrowly defined policy failures have led them to extreme acts of publicity that feed their sense of urgency. In contrast, Joe Biden's American Inflation Reduction Act of 2022 represents the most significant move toward green energy in US history. The law did not impress groups like Letzte Generation, but Climate Radicals shows that old-fashioned political compromise and incremental progress might be the only way for governments to fight climate change.
