A total of 270 flights were canceled at Germany's busiest airports after environmental activists launched a coordinated effort to disrupt air travel across Europe at the height of the summer vacation season to highlight the threat posed by climate change. Frankfurt Airport said flights were halted for safety reasons after climate activists breached security fences in the early morning. The airport said that all runways were back in operation by 7:50 a.m. local time. Climate activists staged or attempted similar actions in Finland, Norway, Switzerland and Spain on Wednesday. Environmental groups said they planned to target airports around Europe this summer to remind people about the link between fossil fuels and climate change.
