Science minister has tough job to follow
As the youngest member of the Cabinet, Liz Truss will be welcomed by many as marking a distinct change from the divisive Owen Paterson.
Mr Paterson's views on climate change, genetically modified foods and especially the badger cull earned the deep distrust of environmental campaigners while generating support among farmers.
Greens were quick to put the boot into the departing Mr Paterson dubbing him the "worst environment secretary in decades".
"Mr Paterson has wilfully ignored scientific evidence on climate change, championed pesticide firms instead of bees and massively underinvested in flood defences, leaving thousands of households at risk of future flooding," said Andy Atkins from Friends of the Earth.
But Mr Paterson's adoption of new measures to tackle bovine TB including the controversial badger cull won him hearts and minds in the countryside.
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".
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.
