Extreme events linked to climate change, such as the heatwave in Europe this year, are occurring sooner than expected, an ex-chief scientist says. Prof Sir David King says he’s been scared by the number of extreme events, and he called for the UK to advance its climate targets by 10 years.

But the UN’s weather chief said using words like “scared” could make young people depressed and anxious.

Campaigners argue that people won’t act unless they feel fearful.

Speaking to the BBC, Prof King, a former chief scientific adviser to the government, said: “It’s appropriate to be scared. We predicted temperatures would rise, but we didn’t foresee these sorts of extreme events we’re getting so soon.”

He said the world had changed faster than generally predicted in the fifth assessment ...

Investing $1.8 trillion over the next decade – in measures to adapt to climate change – could produce net benefits worth more than $7 trillion. This is according to a global cost-benefit analysis setting out five adaptation strategies.

The analysis was carried out by the Global Commission on Adaptation – a group of 34 leaders in politics, business and science.

They say the world urgently needs to be made more “climate change resilient”.

• 12 years to save the planet? Make that 18 months
• Big lifestyle changes needed to cut emissions
• Climate change is ‘shrinking winter’

The commission, led by former UN Secretary-General Ban Ki-moon, World Bank chief executive Kristalina Georgieva and Microsoft co-founder Bill Gates, argues that it is an urgent moral obligation of richer countries to invest ...

It’s a historic week for climate change in the Democratic Party.

In the same 12-hour span, Senator Bernie Sanders unveiled his plan to pass a gargantuan $16 trillion Green New Deal as president, while Governor Jay Inslee of Washington—who ran an unprecedented, bluntly climate-focused campaign—dropped out of the 2020 primary.

Then, this afternoon, the Democratic National Committee rejected a proposal to hold a climate-centered debate in the primary—even though nearly every candidate had endorsed the idea.

Germany says it plans to take a more active role in Arctic affairs, citing the far north’s growing ecological, political and economic significance as a result of climate change.

Cabinet passed a resolution Wednesday declaring its intention to send German experts to advise the Arctic Council. It also plans to campaign for an expansion of environmental protection areas in the Arctic and explore the potential that the increasingly ice-free Northwest and Northern Passages have for shipping during the summer.

German Chancellor Angela Merkel said Tuesday after a meeting with Nordic leaders that her country, which is an observer in the Arctic Council, will “keep an eye on the strategic role of the Arctic.”

Merkel said Germany would seek to prevent the Arctic from becoming “an obje...

When pollsters informed President Donald Trump that he faces political exposure in the 2020 election with swing voters on environment policy, he decided to respond with a White House address claiming stewardship of clean water, air and oceans.

But as some Trump aides were drafting that speech, others were casting doubt on the significance of a climate threat to a key battleground state: the degradation of coral reefs in Florida.

Weeks before, a senior intelligence analyst at the State Department had submitted a draft of planned testimony to Congress detailing the national security implications of climate change for White House review.

Among the edits that the analyst, Rod Schoonover, received back from the White House was a novel argument...

The heat wave that smashed high temperature records in five European countries a week ago is now over Greenland, accelerating the melting of the island’s ice sheet and causing massive ice loss in the Arctic. Greenland, the world’s largest island, is a semi-autonomous Danish territory between the Atlantic and Arctic oceans that has 82 per cent of its surface covered in ice. 

The area of the Greenland ice sheet that is showing indications of melt has been growing daily, and hit a record 56.5 per cent for this year on Wednesday, said Ruth Mottram, a climate scientist with the Danish Meteorological Institute. She says that’s expected to expand and peak on Thursday before cooler temperatures slow the pace of the melt.

More than 10 billion tonnes of ice was lost to the oceans by surf...

The level of carbon now in the atmosphere hasn’t been seen in 12 million years, a Harvard scientist said in Chicago Thursday, and this pollution is rapidly pushing the climate back to its state in the Eocene Epoch, more than 33 million years ago, when there was no ice on either pole.

“We have exquisite information about what that state is, because we have a paleo record going back millions of years, when the earth had no ice at either pole. There was almost no temperature difference between the equator and the pole,” said James Anderson, a Harvard University professor of atmospheric chemistry best known for establishing that chlorofluorocarbons were damaging the Ozone Layer.

“The ocean was running almost 10ºC warmer all the way to the bottom than it is today,” Anderson said of thi...

The US is a hotbed of climate science denial when compared with other countries, with international polling finding a significant number of Americans do not believe human-driven climate change is occurring.

A total of 13% of Americans polled in a 23-country survey conducted by the YouGov-Cambridge Globalism Project agreed with the statement that the climate is changing “but human activity is not responsible at all”. A further 5% said the climate was not changing.

Only Saudi Arabia (16%) and Indonesia (18%) had a higher proportion of people doubtful of manmade climate change.

Americans were also more likely than any other western country polled to say they did not know whether the climate was changing or people were responsible – a total of 13% said this.

But desp...

Reef corals in equatorial regions are going to start moving toward the poles as climate change takes hold, scientists have said. By analyzing the ranges of reefs from the fossil record, researchers are able to build a picture of how these systems respond to climate change—and then project how they might respond under future global warming.

Findings show that, under two climate change scenarios set out by the Intergovernmental Panel on Climate Change (IPCC), reefs are likely to expand their poleward range—in both the Northern and Southern hemispheres—and decline in the regions they currently occupy. This will mean a fundamental change to the locations of reef corals in the future.

The study, published in the journal Royal Society Open Science, examines the fossil record for ho...

Every year the nearly 400 billion trees in the Amazon rain forest and all the creatures that depend on them are drenched in seven feet of rain — four times the annual rainfall in London. This deluge is partly due to geographical serendipity. Intense equatorial sunlight speeds the evaporation of water from sea and land to sky, trade winds bring moisture from the ocean, and bordering mountains force incoming air to rise, cool and condense. Rain forests happen where it happens to rain.

But that’s only half the story. Life in the Amazon does not simply receive rain — it summons it. All of that lush vegetation releases 20 billion tons of water vapor into the sky every day. Trees saturate the air with gaseous compounds and salts. Fungi exhale plumes of spores...
