President Barack Obama’s climate change policy is in crisis amid a barrage of US lawsuits challenging goverment directives and the defection of major corporate backers for his ambitious green programmes.
The legal challenges and splits in the US climate consensus follow revelations of major flaws in the UN Intergovernmental Panel on Climate Change (IPCC) report, which declared that global warming was no longer scientifically contestable.
Critics of America’s Environmental Protection Agency (EPA) are now mounting a series of legal challenges to its so-called “endangerment finding” that greenhouse gases are a threat to human health.
That ruling, based in part on the IPCC’s work, gave the agency sweeping powers to force business to curb emissions under the Clean Air Act. An initial showdown is expected over rules on vehicle emissions.
Oil-rich Texas, the Lone Star home state of Mr Obama’s predecessor George W Bush, is mounting one of the most prominent challenges to the EPA, claiming new regulations will impose a crippling financial toll on agriculture and energy producers.

The rest here.

P.S. Add Virginia to the list of states suing the EPA.
