Suzanne Goldenberg:

It is nearly 27 years now since a Nasa scientist testified before the US Senate that the agency was 99% certain that rising global temperatures were caused by the burning of fossil fuels.

And the Senate still has not got it – based on the results of three symbolic climate change votes on Wednesday night.

It’s wholly embarrassing. It’s ultimately terrifying, as well. Not only because we have leaders who refuse to accept the facts, but that so many Americans still vote such people into positions of power.
