The world’s vast permafrost regions contain three times more carbon than all living vegetation. Some are thawing and emitting more and more greenhouse gases.
#Permafrost cannot refreeze back. "Once you pass the permafrost’s threshold and the ice has gone and the landscape has changed, it is not going to come back for hundreds of years. On a human timescale, those systems have then effectively tipped into a system that will keep emitting carbon for decades or centuries."
"Unfortunately, there are no feasible geoengineering solutions on a broad scale. The only way to limit the thawing of millions of square kilometres is to reduce emissions rapidly. We need to act urgently."

Dit bericht wil ik helemaal niet boosten. Zeker niet voor de 2e keer.
Maar ik doe het toch. Omdat jullie dit ook niet willen zien. En toch al weten. En liever ook niet over willen denken.

Day 72: In Papua you can never be sure about schedules and timing until the ship has actually taken off. After an obligatory 3 hour delay, I am eventually about to embark for the previous to last stage of my journey: 4 days of navigation over a 1,100km route: Lae-Umboi-Gloucester-Kimbe-Rabaul. I still don't know how to manage the last stretch from Rabaul to Buka....
I can't believe that after 70 days of travel I am just about to complete the 28,000km dividing Italy from the Solomons without flying! It will count nothing in terms of overall greenhouse emissions, but for me, now, it's everytghing I can do to for this wonderful fragile planet. 91/
I slow travel mainly to reduce my carbon footprint (by 10 times according to available estimates) but also to experience travel as most people in this world do.

There is an urgent need for rapid, large-scale reductions in greenhouse gas emissions to limit further global warming together with well-planned adaptation measures to address the climate change that is already occurring.

Siberia's growing methane threat could offset 20% of global methane reduction targets by 2050
The #Arctic is warming at an accelerating pace. As #permafrost thaws across vast areas and wildfires become more frequent, large amounts of #methane (CH4) are being released. Together, these changes are reshaping the region's #GreenhouseGas emissions and further intensifying climate change.
In a study published in Science on August 6, an international team led by Professor Liu Yi from the Institute of Atmospheric Physics #IAP of the Chinese Academy of Sciences investigated how #CH4 #emissions in #Siberia are evolving under #ClimateChange. The study showed how atmospheric circulation promotes #wildfire activity and #methanogenesis and thereby drives the recent sharp rise in CH4 emissions.

The terrifying scenes we’ve seen so far this summer are the latest part of a pernicious long-term pattern.
Across the world, the past 11 years have been the 11 hottest ever recorded – and with a super strength El Niño forming in the Pacific which could pour yet more fuel on the fire, that trend is all but certain to continue.
The climate emergency is here – and no one can say they didn’t see it coming.

Extreme heat and its consequences are the result of a fossil fuel policy that is completely irresponsible and extremely dangerous.

What people now nervously call “the new normal” is, in truth, not normal and but a taste of things to come. These extreme weather events we are increasingly experiencing – and the warlike mood they create – represent attacks on our soil.
They are a call to mobilize.

While renewables are cheaper than fossil fuels in nearly all circumstances, fossil fuels are more profitable, because useful reserves are limited and can each be monopolised by a single corporation, while prices can suddenly take flight in times of war or chaos.
Almost all the very rich are heavily invested in them.

A small chorus of right-leaning critics are trying to convince politicians that climate action is deeply unpopular, downplaying its seriousness in the process. They accept the reality of human-made climate change, but believe the impact of it won’t be as big as people argue, and that policies involved in mitigating these impacts will be expensive and difficult.

It’s as if we launched a war against nature, and that has turned place after place into something that resembles a war zone. The climate movement is a peace movement, a movement to end this war and its casualties.

Heatwaves have been made more intense and more likely by the fossil fuel-driven climate crisis. The heatwave that affected western Europe at the end of June was the most severe and widespread ever.
A series of huge wildfires, supercharged by the climate crisis, has torched large parts of Europe this summer. Rivers in Europe are facing extremely low flows.

Hungary and Romania have been forced to shut down nuclear reactors. They are increasingly relying on expensive power imports as heatwave conditions increase demand for electricity. Both countries use water from the Danube as coolant for their reactors.

We're seeing fewer decent-paid jobs and the need for universal basic income as we install more machines that replace former high-level work

There are no bus schedules, no tickets, and buses depart when they are full. I am getting to the main departing point in Madang when it's already late in the morning - but I really wanted to talk about locals about coastal erosion in the city. Fortunately, I still find a place for me on probably the last bus, and two seats are allocated to my bulky luggage. Off we go for the last stop in Papua island before hopefully embarking for the Bismarck archipelago.
It takes 6 hours to cover 212km on "Ramu Sugars" road. It was even slower 3 yrs ago with unpaved track

The climate emergency and the breakdown of nature poses a dramatically growing risk to the global economy. If you destroy nature, you destroy the core on which our economies depend.

European megafires show how fast climate-driven extreme heat and dry landscapes can turn wildfires into devastating national disasters.
Humanity continuing to burn colossal amounts of coal, oil and gas is making these conditions more dangerous, and these megafires more deadly and destructive.

The Trump administration is actively working to make the climate crisis worse, taking at least 97 actions that weaken or eliminate curbs on carbon pollution or undercut the USA’s ability to cope with the consequences. For an administration glib about the genuine risks from a changing climate, the smoke crossing our shared border is not an export. It is a receipt.

The US has flipped so far beyond recalcitrance during Trump’s second stint in the White House that it can only be described as waging ecological warfare. The phallic mantra of “drill, baby, drill” is guiding an administration for which the faintest speck of care for the Earth is already too woke.

“The climate alarm is blaring, from every direction. Around the world, climate-driven disasters are reaching nightmare proportions, as the costs of humanity’s addiction to burning coal, oil and gas keep spiraling upwards.
These record-breaking wildfires tearing through France, Spain and other parts of Europe, forcing mass evacuations and hammering regional and national economies, follow brutal heatwaves that have dried out landscapes.
With the mercury set to soar again this week, the awful costs of this climate crisis – both human and economic – are now reaching national emergency levels.”

Exciting sighting on our way back from the #Highlands
The RRS Sir David #Attenborough on its way to Iceland and beyond.
Currently it is bringing an international team of researchers to Greenland for a six-week expedition to study how quickly the ice sheet’s rapidly melting fjord glaciers are pushing the Atlantic Ocean towards a critical climate #TippingPoint

🌊 Long before the term #TippingPoint was coined, oceanographer Henry Stommel discovered that the thermohaline circulation could exhibit multiple equilibria—&that small perturbations could trigger transitions between them. His 1961 Tellus paper underpins today’s research on the #AMOC.
📃 On the occasion of Tellus’s relaunch&the paper’s 65th anniversary, our director Jochem Marotzke analyzes its reception from the circuitous early history to its lasting legacy: https://tellusjournal.org/articles/10.16993/tellus.4175

Day 65: After a smooth 9-hour boat ride over the Sepik river, we made it to Sisimagung, Northern Papua. This is the 65th day of my no-fly trip from Italy to the Solomon islands. The coastline is beautiful, what you could describe as paradise on earth. Coconut trees gently bend over sandy beaches and the sound of the waves quietly resound among villagers busy with their fishing nets or cooking earths. It is then all the more upsetting that this beauty is slowly but incessantly being destroyed by sea level rise. This is what Jeffery Bae, a local resident, tells me in the few hours I have here before getting on a truck to Madang. It seems impossible that a sea so quiet can become the agent of destruction, but this is precisely what happens, as Jeffery shows traditional houses made with sago and bamboo leaves having been dismantled by the latest storm surges.
"We will have to relocate", tells me Jeffrey with an empty, "but we don't know where, because right behind our village there's a swamp".
Once more, I hear the same story: no help from national, regional governments, and neither from international organisations.
How many million stories are similar to Jeffrey's, and I wouldn't hear were it not for my slow travel.Check interview here:
