(The Guardian) – One of the fathers of climate science is calling for a wave of lawsuits against governments and fossil fuel companies that are delaying action on what he describes as the growing, mortal threat of global warming.Former NASA scientist James Hansen says the litigate-to-mitigate campaign is needed alongside political mobilisation because judges are less likely than politicians to be in the pocket of oil, coal and gas companies.“The judiciary is the branch of government in the US and other countries that is relatively free of bribery. And bribery is exactly what is going on,” he told the Guardian on the sidelines of the UN climate talks in Bonn.Without Hansen and his fellow NASA researchers who raised the alarm about the effect of carbon emissions on global temperatures in the 1980s, it is possible that none of the thousands of delegates from almost 200 countries would be here.But after three decades, he has been largely pushed to the fringes. Organisers have declined his request to speak directly to the delegates about what he sees as a threat that is still massively underestimated.Instead he spreads his message through press conferences and interviews, where he cuts a distinctive figure as an old testament-style prophet in an Indiana Jones hat.He does not mince his words. The international process of the Paris accord, he says, is “eyewash” because it fails to put a higher price on carbon. National legislation, he feels, is almost certainly doomed to fail because governments are too beholden to powerful lobbyists. Even supposedly pioneering states like California, which have a carbon cap-and-trade system, are making things worse, he said, because “half-arsed, half-baked plans only delay a solution.”For Hansen, the key is to make the 100 big “carbon majors” – corporations like ExxonMobil, BP and Shell that are, by one account, responsible for more than 70% of emissions – pay for the transition to cleaner energy and greater forests. Until governments make them do so by introducing carbon fees or taxes, he says, the best way to hold them to account and generate funds is to sue them for the damage they are doing to the climate, those affected and future generations. […]He feels a growing sense of urgency. Current government commitments are so inadequate that temperature rises are currently on course to exceed 3C by the end of the century. Hansen says that would mean existing problems – rising sea levels, displacement by flooding, droughts disrupting food production, wildfires consuming forests, worsening storms and hurricanes – would get three times worse.“Three degrees would be disastrous. You can imagine the planet becoming ungovernable because we would lose the coastal cities where most people live … You’ll see migrants from those parts of the world and also so much disruption to the centres of wealth. So we can’t go down that path.” [more]
