At least five reef islands in the remote Solomon Islands have been lost completely to sea level rise and coastal erosion, and a further six islands have been severely eroded. Sea level rise, erosion and coastal flooding are some of the greatest challenges facing humanity from climate change. The islands lost to the sea range in size from one to five hectares and supported dense tropical vegetation that was at least 300 years old.

Nuatambu Island — home to 25 families — has lost more than half of its habitable area, with 11 houses washed into the sea since 2011.

This is the first scientific evidence, published in Environmental Research Letters, that confirms the numerous anecdotal accounts from across the Pacific of the dramatic impacts of climate change on coastlines and people.

A loss of snow and ice cover are the main reasons for a reduction in the Arctic’s ability to reflect heat, not soot as had been previously thought. The capacity of the Arctic to reflect heat is determined by something known as the albedo effect. This is a measurement of how well a surface, such as snow or ice, bounces sunlight back into space.

Scientists say soot is not the major contributor, as levels have dropped recently, while warming has continued.

The findings have been published in the Proceedings of the National Academy of Sciences.

The Arctic region has warmed significantly since the 1980s, up to three times as much as the average seen elsewhere across the globe.

Much of this warming has been attributed to the reduction of the surface albedo effect.

Cutting the speed of ships has huge benefits for humans, nature and the climate, according to a new report. A 20% reduction would cut greenhouse gases but also curb pollutants that damage human health such as black carbon and nitrogen oxides. This speed limit would cut underwater noise by 66% and reduce the chances of whale collisions by 78%. UN negotiators will meet in London this week to consider proposals to curb maritime speeds.

Ships, of all sorts and sizes, transport around 80% of the world’s goods by volume. However they are also responsible for a significant portion of global greenhouse emissions thanks to the burning of fuel.

Shipping generates roughly 3% of the global total of warming gases – that’s roughly the same quantity as emitted by Germany.

While shipping wasn’t covered...

Yesterday, the state of New York faced off with ExxonMobil for oral arguments in the trial alleging that the company misled investors by providing false assurances that the company was adequately costing climate-related risks. But win or lose, that doesn’t mean an end to deliberate misinformation campaigns. Here’s what we should all know about how to resist those efforts by Exxon and other big corporate actors.

Scientists have known for decades that the burning of fossil fuels is causing climate change. There is so much evidence that at least 97% of climate scientists agree that humans are causing global warming. It’s as settled as the link between smoking and cancer.

The fossil fuel industry has known about the role of its products in global warming for 60 years...

The UK government must tell the public small, easy changes will not be enough to tackle climate change, warn experts.

Researchers from Imperial College London say we must eat less meat and dairy, swap cars for bikes, take fewer flights, and ditch gas boilers at home.

The report, seen by BBC Panorama, has been prepared for the Committee on Climate Change, which advises ministers how to cut the UK’s carbon footprint.

It says an upheaval in our lifestyles is the only way to meet targets.

The government has passed a law obliging the country to cut carbon emissions to net zero by 2050.

It is “going further and faster than any other developed nation to protect the planet for future generations”, a government spokesperson told BBC Panorama. “If we can go faster, we will.”

But the new report warns...

Google has made “substantial” contributions to some of the most notorious climate deniers in Washington despite its insistence that it supports political action on the climate crisis. Among hundreds of groups the company has listed on its website as beneficiaries of its political giving are more than a dozen organisations that have campaigned against climate legislation, questioned the need for action, or actively sought to roll back Obama-era environmental protections.

The list includes the Competitive Enterprise Institute (CEI), a conservative policy group that was instrumental in convincing the Trump administration to abandon the Paris agreement and has criticised the White House for not dismantling more environmental rules.

Haribon Foundation stood in solidarity with millions of people across the planet at the recent Global Climate Strike to demand immediate and concrete actions from every individual, especially the decision-makers, to provide solutions to the worsening climate emergency. As the words of 16-year-old Greta Thunberg resoundingly urges, all sectors should “act as if our house is on fire.”

Climate change is not an issue separate from biodiversity loss, as one inevitably affects the other.

For instance, the destruction, degradation and loss of forests over the past decades have dramatically increased the amount carbon dioxide in the atmosphere, thereby amplifying the greenhouse gas effect.

This phenomenon has led to increased global temperature and heat waves...

German Research Vessel Polarstern has found a location to begin its year-long drift in Arctic sea-ice. The ship, which will head the North Pole’s biggest scientific expedition, will settle next to a thick ice floe on the Siberian side of the ocean basin. The precise location is 85 degrees north and 137 degrees east.

Hundreds of investigators will use it as a base from which to probe the impacts of climate change at the top of the world.

“After a brief but intensive search, we’ve found our home for the months to come,” said expedition leader Prof Markus Rex, from the Alfred Wegener Institute (AWI).

“It may not be the perfect floe but it’s the best one in this part of the Arctic and offers better working conditions than we could have expected after a warm Arctic summer.”

Climate change is devastating our seas and frozen regions as never before, a major new United Nations report warns. According to a UN panel of scientists, waters are rising, the ice is melting, and species are moving habitat due to human activities. And the loss of permanently frozen lands threatens to unleash even more carbon, hastening the decline.

There is some guarded hope that the worst impacts can be avoided, with deep and immediate cuts to carbon emissions.

This is the third in a series of special reports that have been produced by the Intergovernmental Panel on Climate Change (IPCC) over the past 12 months.

The scientists previously looked at how the world would cope if temperatures rose by 1.5C by the end of this century...
