When it comes to global warming, melting ice caps and scorching heat waves often top the list of big worries. But now, just the act of worrying itself is allegedly becoming a new consequence of dreaded climate change. One new form of anguish is for survivors of extreme weather events – which kind of makes sense – but there’s apparently a special mental burden being carried by climate activists who one psychiatrist says are suffering from anticipatory anxiety and pre-traumatic stress disorder. Supposedly adding to the problem is that politicians aren’t doing enough to address their climate concerns, causing them to feel vulnerable and probably just not well understood.
