More than a quarter of Amazon basin releasing more carbon than it absorbs
More than a quarter of the Amazon basin is now releasing more carbon than it absorbs, according to a comprehensive study.
Brazilian researchers flew an aircraft over the rainforest every two weeks for nine years, taking air samples from just above the canopy all the way up to 4.5km.
They found that the eastern side of the Amazon, which accounts for around 28% of the total area, is losing more carbon as a result of deforestation than is being removed from the atmosphere by the growth of trees.
Some of the carbon is lost through fires, deliberately started to clear the forest for agriculture.

But the knock-on effect of an absence of trees is local climate change, with rising temperatures and reduced rainfall accelerating the decline of surrounding areas of forest. Parts of the Amazon have flipped from being a carbon sink to a carbon source.
Mark Wright, director of science for conservation charity WWF, told Sky News that the research showed the Amazon is at a tipping point, where great swathes of forest could be destroyed by self-perpetuating dieback.
“We’re no longer talking about some dystopian future, this is stuff we can see on the ground, these changes are happening here and now,” he said.
“It’s a warning of what is still come to come.
“We know we are moving towards that inextricable situation where the forest will slowly transform into a more grass-like savannah ecosystem and as a result will push more carbon into the atmosphere.”
The world’s plants have absorbed 25% of fossil fuel emissions since 1960, helping to reduce global warming.
The Amazon rainforest has taken up a significant proportion, storing an estimated 123 billion tonnes in the trees and other vegetation.
But the new research suggests it can’t be relied on in future to mop up carbon dioxide from the atmosphere because human activity is disrupting the delicate ecosystem.
The researchers, led by National Institute for Space Research in Brazil, found that on the lush western side of the Amazon basin slightly more carbon is being absorbed through photosynthesis than is being released by dead trees and human impact on the forest.
But it was a significantly different story on the eastern side, where 27% of the forest has been lost, more than twice the rate in the west.
Results published in the journal Nature show that the area has switched from being a carbon sink to a net source during the nine years of the study, with local climate change destabilising the delicate ecosystem.
The researchers say that in the drier months of August to October the temperature in the eastern Amazon has increased by between 1.9C and 2.5C over 40 years. Rainfall has decreased by between 24% and 34%.
The researchers say there is a direct link between the changing climate and tree loss.
Human activity is disrupting the Amazon’s delicate ecosystem
The Amazon receives an average of more than 2m of rain a year, with between a quarter and a third of it resulting from moisture released by trees.
With a shrinking forest in the east the atmosphere is drier, stunting the growth of remaining trees and reducing the amount of carbon they absorb.
Some scientists have predicted that if the Amazon reaches a tipping point it will retreat to cover only a relatively small area in the west, with a devastating impact on biodiversity and atmospheric carbon.
But Mark Wright said: “The future is potentially very, very bleak, but it’s not too late.
“If we follow the science, we can clearly see there is scope to do really good agricultural development in Brazil, in a way that will boost their economy, in a way that does not require further degradation.
“If we can concentrate on restoring those lands there is still hope for preventing that kind of runaway process.
“But we have to act now, we can’t keep pushing this off.”

Daily Climate Show – featuring a ‘living laboratory’
Sky News has launched the first daily prime time news show dedicated to climate change.
The Daily Climate Show is broadcast at 6.30pm and 9.30pm Monday to Friday on Sky News, the Sky News website and app, on YouTube and Twitter.
Hosted by Anna Jones, it follows Sky News correspondents as they investigate how global warming is changing our landscape and how we all live our lives.
The show also highlights solutions to the crisis and how small changes can make a big difference.
US president-elect Donald Trump has suggested Israel and Hamas could agree a Gaza ceasefire by the end of the week.
Talks between Israeli and Hamas representatives resumed in the Qatari capital Doha yesterday, after US President Joe Biden indicated a deal to stop the fighting was “on the brink” on Monday.
A draft agreement has been sent to both sides. It includes provisions for the release of hostages and a phased Israeli troop withdrawal from Gaza.
Qatar says Israel and Hamas are at their “closest point” yet to a ceasefire deal.
Two Hamas officials said the group has accepted the draft agreement, with Israel still considering the deal.
An Israeli official said a deal is close but “we are not there” yet.
More than 46,500 Palestinians have been killed in Gaza since Israel launched its ground offensive in the aftermath of the 7 October attacks, according to the territory’s Hamas-run health ministry.

Biden hails possibility of agreement
President Biden said it would include a hostage release deal and a “surge” of aid to Palestinians, in his final foreign policy speech as president.
“So many innocent people have been killed, so many communities have been destroyed. Palestinian people deserve peace,” he said.
“The deal would free the hostages, halt the fighting, provide security to Israel, and allow us to significantly surge humanitarian assistance to the Palestinians who suffered terribly in this war that Hamas started.”
Qatari mediators have sent Israel and Hamas a draft proposal for an agreement to halt the fighting.

Trump: ‘We’re very close’
President-elect Donald Trump has also discussed a possible peace deal during a phone interview with the Newsmax channel.
“We’re very close to getting it done and they have to get it done,” he said.
“If they don’t get it done, there’s going to be a lot of trouble out there, a lot of trouble, like they have never seen before.
“And they will get it done. And I understand there’s been a handshake and they’re getting it finished and maybe by the end of the week. But it has to take place, it has to take place.”

Israeli official: Former Hamas leader held up deal
Speaking on Tuesday as negotiations resumed in Qatar, an anonymous Israeli official said that an agreement was “close, but we are not there”.
They accused Hamas of previously “dictating, not negotiating” but said this has changed in the last few weeks.
“Yahya Sinwar was the main obstacle for a deal,” they added.
Sinwar, believed to be the mastermind of the 7 October attacks, led Hamas following the assassination of his predecessor but was himself killed in October last year.
Under Sinwar, the Israeli official claimed, Hamas was “not in a rush” to bring a hostage deal but this has changed since his death and since the IDF “started to dismantle the Shia axis”.

Biden: ‘Never, never, never, ever give up’
Iran ‘weaker than it’s been in decades’
Yesterday, President Biden also hailed Washington’s support for Israel during two Iranian attacks in 2024.
“All told, Iran is weaker than it’s been in decades,” the president said.
Mr Biden claimed America’s adversaries were weaker than when he took office four years ago and that the US was “winning the worldwide competition”.
“Compared to four years ago, America is stronger, our alliances are stronger, our adversaries and competitors are
weaker,” he said.
“We have not gone to war to make these things happen.”
The US president is expected to give a farewell address on Wednesday.
A draft ceasefire deal on the table between Israel and Hamas would see 33 hostages set free and a phased withdrawal of IDF forces from parts of Gaza.
President Joe Biden said an agreement to stop the fighting was “on the brink” and high level negotiations between the two sides resumed in Qatar on Tuesday.
The deal would see a number of things happen in a first stage, with negotiations for the second stage beginning in the third week of the ceasefire.
It would also allow a surge in humanitarian aid into Gaza, which has been devastated by more than a year of war.
Details of what the draft proposal entails have been emerging on Tuesday, reported by Israeli and Palestinian officials.

Hostages to be returned
In the first stage of the potential ceasefire, 33 hostages would be set free.
These include women (including female soldiers), children, men over the age of 50, wounded and sick.
Israel believes most of these hostages are alive but there has not been any official confirmation from Hamas.
In return for the release of the hostages, Israel would free more than 1,000 Palestinian prisoners and detainees.
People serving long sentences for deadly attacks would be included in this but Hamas fighters who took part in the 7 October attack would not be released.
An arrangement to prevent Palestinian “terrorists” from going back to the West Bank would be included in the deal, an anonymous Israeli official said.

Phased Israeli withdrawal from Gaza
The agreement also includes a phased withdrawal of Israeli forces from Gaza, with IDF troops remaining in the border perimeter to defend Israeli border towns and villages.
Security arrangements would be implemented at the Philadelphi corridor – a narrow strip of land that runs along the border between Egypt and Gaza – with Israel withdrawing from parts of it after the first few days of the deal.
The Rafah Crossing between Egypt and Gaza would start to work gradually to allow the crossing of people who are sick and other humanitarian cases out of Gaza for treatment.
Unarmed North Gaza residents would be allowed to return to their homes, with a mechanism introduced to ensure no weapons are moved there.
“We will not leave the Gaza Strip until all our hostages are back home,” the Israeli official said.
What will happen to Gaza in the future?
There is less detail about the future of Gaza – from how it will be governed, to any guarantees that this agreement will bring a permanent end to the war.
“The only thing that can answer for now is that we are ready for a ceasefire,” the Israeli official said.
“This is a long ceasefire and the deal that is being discussed right now is for a long one. There is a big price for releasing the hostages and we are ready to pay this price.”
The international community has said Gaza must be run by Palestinians, but there has not been a consensus about how this should be done – and the draft ceasefire agreement does not seem to address this either.
In the past, Israel has said it will not end the war leaving Hamas in power. It also previously rejected the possibility of the Palestinian Authority, which exercises limited governing powers in the West Bank, from taking over the administration of Gaza.
Since the beginning of its military campaign in Gaza, Israel has also said it would retain security control over the territory after the fighting ends.
