A group calling itself the International Climate Science Coalition (ICSC) chose today, Earth Day, to rain on the climate change parade.

The ICSC cannily chose the day to release the names of 500 “climate realists” who endorsed its Manhattan Declaration on Climate Change, which calls on world leaders to “reject the views expressed by the United Nations Intergovernmental Panel on Climate Change (IPCC)” and Al Gore’s popular movie, An Inconvenient Truth.”
