My father in law was a massive climate change denier until some trees started dying on his property.

He called out an arborist, and the arborist clearly explained that there wasn't enough rain anymore to support the number of trees on his land, and that the forest was slowly receding as the older/bigger trees took all the water from the other trees.

It finally dawned on him that a place where trees used to happily live to hundreds of years old could no longer support trees.

Still, he thinks CO2 is a con job cooked up by China and that global warming is divine punishment. But it's a good reminder that a lot of denialists are waiting for a personal, practical reason to care.

Four out of five denialists agree!
