Testimony to US Congress will also criticize lobbyists. "Revolutionary" policies needed to tackle crisis.
New York - James Hansen, one of the world's leading climate
scientists, will today call for the chief executives of large fossil
fuel companies to be put on trial for high crimes against humanity and
nature, accusing them of actively spreading doubt about global warming
in the same way that tobacco companies blurred the links between
smoking and cancer.
Hansen will use the symbolically charged 20th anniversary of his groundbreaking speech
to the US Congress - in which he was among the first to sound the alarm
over the reality of global warming - to argue that radical steps need
to be taken immediately if the "perfect storm" of irreversible climate
change is not to become inevitable.
Speaking before Congress again, he will accuse the chief
executive officers of companies such as ExxonMobil and Peabody Energy
of being fully aware of the disinformation about climate change they
are spreading.
In an interview with the Guardian he said: "When you are in
that kind of position, as the CEO of one the primary players who have
been putting out misinformation even via organisations that affect what
gets into school textbooks, then I think that's a crime."
He is also considering personally targeting members of
Congress who have a poor track record on climate change in the coming
November elections. He will campaign to have several of them unseated.
Hansen's speech to Congress on June 23 1988 is seen as a seminal moment
in bringing the threat of global warming to the public's attention. At
a time when most scientists were still hesitant to speak out, he said
the evidence of the greenhouse gas effect was 99% certain, adding "it
is time to stop waffling".
He will tell the House select committee on energy
independence and global warming this afternoon that he is now 99%
certain that the concentration of CO2 in the atmosphere has already
risen beyond the safe level.
