The tipping point on global warming is close, according to James Hansen,  director at NASA's Goddard Institute for space studies.  

In his speech to congress on 23 June, Hansen has issued his strongest warning yet about the state of the climate. 

He focuses, at one point, on the CEO's of major companies, singling out Exxon and Peabody in particular.  "In my opinion, these CEOs should be tried for high crimes against humanity and nature."

The crimes, as we know, are the continued funding of the denial industry, peddling confusion and doubt in the public.  This week also saw an new poll in the UK paper, The Observer, pointing out the rise of climate scepticism, which follows an earlier poll in the US saying the same thing.  The US poll, though, showed that the rise was amongst Republicans. 

That would be the Republicans who are the denial industry's audience.  

So again we point to the 23 organisations that Exxon continues to fund.  The sooner they stop, the better.
