Davey declares Britain must lead climate change fight

On the eve of a ground-breaking UN report into the impacts of climate change, Energy Secretary Ed Davey has declared Britain must spearhead the worldwide battle against global warming.

Climate change is "hugely threatening our way of life, in the UK, Europe and the world," Mr Davey told The Observer.

"Not to lead is deeply irresponsible. If you don't lead, you will not bring others with you," the Lib Dem MP said.

His comments come as the UN's Intergovernmental Panel on Climate Change prepares to release a report that is expected to warn of catastrophic consequences to food supplies, livelihoods, health and security across the world if climate change remains unchecked.

Ex-Archbishop: Western lifestyles 'cause climate change'

The former Archbishop of Canterbury has attacked Western lifestyles for causing climate change that is "pushing the environment towards crisis".

Writing in The Sunday Telegraph, Dr Rowan Williams said: "Rich, industrialised countries, including our own, have unquestionably contributed most to atmospheric pollution.

"Both our present lifestyle and the industrial history of how we created such possibilities for ourselves have to bear the responsibility for pushing the environment in which we live towards crisis.”

On Monday, the UN's Intergovernmental Panel on Climate Change is due to publish its latest study on the consequences of the predicted rise in global temperatures.


Lights out at 8:30pm across the world for Earth Hour

Thousands of people around the world will switch off their lights for one hour between 8.30pm to 9.30pm local time as part of a global effort to shine a spotlight on climate change in the 2014 edition of Earth Hour.

This symbolic global initiative organized by the World Wildlife Fund (WWF) started as a lights-off event in Sydney, Australia in 2007. Since then it has grown to engage over 150 countries and hundreds of millions of people.

The date traditionally coincides with the Spring and Autumn equinoxes in the northern and southern hemispheres respectively, which allows for near coincidental sunset times in both hemispheres, thereby ensuring the greatest visual impact for a global “lights out” event.

Hammond: 'Climate change clearly a factor in weather'

Conservative Defence Secretary Philip Hammond said:

Climate change is clearly happening, it is clearly a factor in the weather patterns that we are seeing.

That's why we are investing significant amounts of money in increasing our flood resilience in the UK.

Of course these floods are a terrible tragedy for all the people affected, but we shouldn't forget that hundreds of thousands of properties have been protected from flooding by the investment we've made over recent years.

Miliband: Climate change cross-party consensus needed

Mr Miliband said: "The science is clear. The public know there is a problem. But, because of political division in Westminster, we are sleepwalking into a national security crisis on climate change. The terrible events of the last few weeks should serve as a wake-up call for us all."

The Labour leader said he had "genuinely believed" that Mr Cameron was sincere about his passion for green issues while in Opposition, but sacking Charles Hendry as energy minister and appointment of Owen Paterson - viewed as a climate change sceptic - as Environment Secretary suggested otherwise.


Miliband says the 'dice are loaded' over climate change

Labour leader Ed Miliband has referred to 2012 as the second wettest winter on record and this winter as a one in 250-year event in explaining his position on climate change.

In an interview with The Observer, Mr Miliband said: "If you keep throwing the dice and you keep getting sixes then the dice are loaded. Something is going on..."

We have always warned that climate change threatens national security because of the consequences for destabilisation of entire regions of the world, mass migration of millions of people and conflict over water or food supplies.

But the events of the last few weeks have shown this is a national security issue in our own country too with people's homes, businesses and livelihoods coming under attack from extreme weather. And we know this will happen more in the future.

– Labour leader Ed Miliband

Miliband: UK 'sleepwalking into a national security crisis'

Ed Miliband has attacked the Prime Minister for giving up the fight against climate change, warning that Britain is "sleepwalking into a national security crisis".

The Labour leader said the winter storms that have been wreaking havoc in the country should serve as a "wake up call".

It was "extraordinary" that the Prime Minister was now portraying climate change merely as "a matter of conscience", when it had been a "core conviction" when he was in Opposition.

Iceberg the size of Manhattan could threaten shipping

An iceberg the size of Manhattan has broken free from a glacier in Antarctica and scientists fear it could last long enough to pose a serious threat to shipping lanes.

"An iceberg that size could survive for a year or longer and it could drift a long way north in that time and end up in the vicinity of world shipping lanes in the Southern Ocean," said Dr Robert Marsh of the University of Southampton.

A team of British scientists have been tracking in the giant iceberg - which measures 21 by 12 miles - since it cracked off from the Pine Island Glacier in July.

Icebergs of such massive proportions break off every two years on average, and are likely to become more common as global warming gathers pace.

Arctic melt 'to blame for UK's soggy summers'

Melting Arctic sea ice may be to blame for the recent spate of soggy summers in the UK, scientists have claimed.

Loss of ice due to climate change is affecting strong air currents high in the atmosphere and as a result, weather systems are being shifted bringing more summer rain to the UK and other parts of northwestern Europe, a new study suggests.

Scientists at the University of Exeter used a computer model to simulate the effects of retreating Arctic sea ice on European climate.

The model produced a pattern of rainfall consistent with an extraordinary run of washed-out summers experienced in the UK between 2007 and 2012.
