Is Obama's climate 'regime change' unstoppable?
"It is not just about disappearing polar bears and disappearing ice caps," said Gina McCarthy, head of the US Environmental Protection Agency (EPA) as she outlined the heavily-trailed Clean Power Plan proposal.
Cutting carbon emissions by a third by 2030, she said, was about "protecting our health and protecting our homes".
President Obama's new plan is not just taking aim at America's hearts and minds, he's going for the lungs as well.
Children with asthma will benefit from the new regulations to clean the air, the EPA chief said.
It is not about the theoretical impact of rising temperatures in far away places. This is a smart thing to do, supporters say, even if the planet wasn't at stake.
US set 'to take very significant step' on climate
President Obama is set to unveil the most significant American attempt yet made to curb carbon dioxide emissions when he announces new restrictions on existing power plants on Monday.
The president is likely to endorse a set of rules drawn up by the Environmental Protection Agency (EPA) that will seek to limit emissions from 1,600 existing facilities that are responsible for about a third of US CO2 emissions.
Warm Texas wind blows green for Mars
This year is turning into a humdinger for those of us lucky enough to collect sprawling climate science reports.
The IPCC, Elvis and the elephant in the room
Everywhere you go in Berlin there are nostalgic echoes of the past - in the shadow of the wall's remnants, old Trabants take tourists on nostalgic car rides to times long gone.
And at the conference centre where IPCC delegates have been ensconced for a week deliberating on how to save the world from dangerous climate change, other ghostly voices have been making their presence felt.
Climate report: Creating a sense of urgency or alarm?
The cool blue cover of the latest IPCC report on the impacts of climate change belies the rather hot stuff within.
Perhaps taking inspiration from their neon loving Japanese hosts, the report is heavy with reds, greens and yellows.
Climate report aims to blossom in Japan
Haiku, high towers and the scent of cherry blossom all come into play as government officials and scientists discuss the global impacts of climate change.
"There are no strangers under the cherry blossoms," said Mr Nobuteru Ishihara, Japan's minister for the environment, as he welcomed members of the Intergovernmental Panel on Climate Change to what's likely to be a fractious session here in Yokohama.
Taking the war out of global warming
I once had a dream (or was it a dram?) in which the things we thought we knew for certain about the world were suddenly turned upside down.
In this strange universe, the cold war seemed to suddenly return, Ireland began to perform consistently at rugby, and arch-climate sceptics began to believe in dangerous levels of global warming.
Frolick and Yap to solve climate change?
Tackling the causes of climate change has worn the patience of some of the world's biggest brains.
Attempts to put together a comprehensive global treaty have stumbled like drunks, somehow remaining on their feet but struggling to gain any forward momentum.
Blue lagoons and higher roads to curb flood threat?
Would a large lagoon the size of 12,000 football fields have prevented the flooding of the Somerset Levels?
According to Roger Falconer, professor of water engineering at Cardiff University, the Bridgewater Bay Lagoon proposal would have helped the waters flow away from the flat lands of the county.
Dabbling ducks struggling in floods
Wildlife organisations are being very careful in assessing the impacts of the recent flooding on species and the environment.
"We are not saying this is a disaster or this is something where wildlife has really suffered," Grahame Madge from the RSPB told me, keenly aware that when people's lives and homes are being threatened by rising waters, concerns about animal life comes a distant second.
