In climate change fight, doomerism is out. Laughter is in

Across the world, groups of activists, teachers and psychologists are tackling one of the world’s most daunting problems — human-caused climate change — with laughter, dancing, hugs and most especially joy.

With a heavy emphasis on what works psychologically, seminars, books and college classes are trying to change how activists approach climate change, by talking more about community and happiness than sacrifice.

Whether it's lobbying a government or getting people to change their behavior, some activists are finding that the missing ingredient is joy.

Instead of being an “eco-pooper” some activists are fighting for the climate with a smile.
