One thing is certain: The thawing of previously frozen landscapes will continue to change the face of high-latitude ecosystems for years to come. For people living in these areas, slumping land and destabilizing soil will mean living with the risks and costs, including buckling roads and sinking buildings.

"This year set to be warmest in 125,000 years, EU scientists say"
Last month exceeded the previous highest October average temperature, from 2019, by 0.4 degrees Celsius, the EU's Copernicus Climate Change Service (C3S) Deputy Director Samantha Burgess said, describing the temperature anomaly as "very extreme".
That has made 2023 as a whole "virtually certain" to be the warmest year recorded, C3S said in a statement.
The heat is a result of continued greenhouse gas emissions from the burning of fossil fuels, combined with the emergence this year of the naturally occurring El Nino climate pattern, which warms the surface waters in the eastern Pacific Ocean.
The current hottest year on record is 2016 — another El Nino year — although 2023 is on course to overtake that.

"The rich are fleeing the climate crisis by scrambling to buy chalets in the Alps"
Prices across 24 resorts in Switzerland and France rose 4.4% on average last year, with a couple of destinations in Switzerland enjoying double-digit price increases.
Rising demand now appears to be driven by nervous customers from sunnier regions looking for a chalet as a second home further from the equator.
“There are clear challenges ahead for ski resorts, not least climate change, the need to upgrade infrastructure, and strict planning rules,” said Kate Everett-Allen, Knight Frank’s head of global residential research.
“But the market is evolving, attracting buyers from further afield (Asia and Middle East) and from southern Europe, as recent heatwaves prompt some second homeowners to pivot northwards.”
"Climate change causes a mountain peak frozen for thousands of years to collapse"
Part of a Swiss mountain's summit has collapsed, sending more than 3.5 million cubic feet (100,000 cubic meters) of rock crashing into the valley below. The incident was likely a result of thawing permafrost — and scientists have warned similar events are to be expected as climate change causes ancient frozen ground to degrade.

I know I'm leaning heavily on the topic but I think it is of huge importance. Like end-of-times (in slow motion) important. The more folk who are seriously concerned about it the better: their votes might help, their voices might help, and maybe enough people making small changes might help.
Well, actually, I think the topic is interesting even it nothing is done to improve it. It is sort of a real-life science fiction horror story. I'm curious how bad it will get in my lifetime and whether humankind will be able to turn it around.
And I found those last two articles noteworthy:
(1) Some rich people are moving to the Alps because of Climate Change
(2) Climate Change might get them anyways.

"Rich nations 'likely' met $100 bn climate finance goal: OECD"
:=:=:=:
:=:=:=:
:=:=:=:
In 2009, richer countries promised to reach $100 billion annually in funding for these priorities by 2020.
Failure to meet the target on time has damaged trust in international climate negotiations.
In the most up to date figures, the OECD said richer countries reached $89.6 billion in total funding for 2021.
"Based on preliminary and as yet unverified data, the goal looks likely to have already been met as of 2022," said OECD Secretary-General Mathias Cormann in the foreword to the latest report.
But he added experts estimate that developing countries will need to spend about a trillion dollars a year by 2025 for climate investments, rising to roughly $2.4 trillion each year between 2026 and 2030.

The threshold was crossed just temporarily and does not mean that the world is at a permanent state of warming above 2 degrees, but it is a symptom of a planet getting steadily hotter and hotter, and moving towards a longer-term situation where climate crisis impacts will be difficult — in some cases impossible — to reverse.
“Our best estimate is that this was the first day when global temperature was more than 2°C above 1850-1900 (or pre-industrial) levels, at 2.06°C,” she wrote.
"World on pace to blow past Paris climate targets, UN says"
The U.N. found global emissions need to fall 42 percent by 2030 to put the world on track to limit temperature rise to 1.5 degrees Celsius by 2050 or by 28 percent to hold temperature increases to the 2 C targeted by the Paris Agreement. Doing so would require a sudden reversal in global emission trends, which have risen steadily in recent decades. The longer it takes the world to meaningfully cut emissions, the more carbon dioxide removal technology will be needed to stabilize global temperatures, the U.N. said.
"Climate on track to warm by nearly 3C without aggressive actions, UN report finds"
The annual Emissions Gap report, which assesses countries' promises to tackle climate change compared with what is needed, finds the world faces between 2.5C (4.5F) and 2.9C (5.2F) of warming above preindustrial levels if governments do not boost climate action.
At 3C of warming, scientists predict the world could pass several catastrophic points of no return, from the runaway melting of ice sheets to the Amazon rainforest drying out.
"Present trends are racing our planet down a dead-end 3C temperature rise," said U.N. Secretary-General Antonio Guterres. "The emissions gap is more like an emissions canyon."

Physicist Richard Feynman would remark "global warming will only make cold places hotter, not places that are already hot hotter".
Apparently he was wrong.
It hit 137 degrees in Rio De Janeiro Brazil . A 23 year old woman died of cardiac arrest from the heat at a Taylor Swift concert there.
The record breaking heatwave is partially do to El Nino, and partially to climate change.

September 2023 is a clear outlier on the graph, marked high above all other anomalies.
I sort of like that informal technical term: ‘gobsmackingly bananas’

Luca Possenti, an author of the study, paints a concerning picture, emphasizing that these changes could result in an increase in underwater noise levels by seven decibels in parts of the North Atlantic. This phenomenon is likely to disrupt communication among marine animals, affecting everything from their reproduction to feeding habits.

"Three positive climate developments"
The climate trajectory, while still poor, has improved since countries signed the Paris Agreement in 2015 and committed to limiting the global temperature rise to "well below" two degrees Celsius above pre-industrial levels, preferably a safer 1.5C.
And the uptake of renewable energy is providing a rare glimmer of hope.

"The past decade was the hottest on record as climate change ‘surged alarmingly,’ WMO reports"
The report, released Tuesday at the COP28 conference in Dubai, found rising concentrations of planet-heating pollution in the atmosphere fueled record land and ocean temperatures and “turbo charged” dramatic glacier loss and sea-level rise during this period.
This year is also expected to be the hottest year, after six straight months of record global temperatures.
Scientists have said this year’s exceptional warmth is the result of the combined effects of El Niño and human-caused climate change, which is driven by planet-warming fossil fuel pollution. A separate analysis released Monday by the Global Carbon Project found that carbon pollution from fossil fuels is on track to set a new record in 2023 – 1.1% higher than 2022 levels.
WMO’s findings on the hottest decade continue a 30-year trend. “Each decade since the 1990s has been warmer than the one before it, and we see no immediate sign of this trend reversing,” WMO Secretary-General Petteri Taalas said in a statement. “We have to cut greenhouse gas emissions as a top and overriding priority for the planet in order to prevent climate change spiralling out of control.”
"Breach of key global warming threshold 'inevitable' as carbon emissions hit record high"
Humanity released 40.6 billion tons (36.8 billion metric tons) of carbon dioxide into the atmosphere in 2023, representing an increase of 1.1% from 2022, according to a new report by an international team of climate scientists.
When added to the emissions created by land-use changes, including deforestation, a total of 45.1 billion tons (40.9 billion metric tons) of carbon dioxide was emitted in 2023. At the current emissions level, the researchers estimate a 50% chance that global warming will exceed 1.5 C consistently in about seven years.

"2023 will officially be the hottest year on record, scientists report"
The analysis from the European Union’s Copernicus Climate Change Service found this year’s global temperature will be more than 1.4 degrees Celsius warmer than pre-industrial levels — close to the 1.5-degree threshold in the Paris climate agreement, and beyond which scientists say humans and ecosystems will struggle to adapt.
Every month since June has been the hottest such month on record, and November piled on. The month was roughly 1.75 degrees warmer than pre-industrial levels, and two days soared beyond 2 degrees, worrying scientists about what this means for the planet in the coming years.
"Climate change is already forcing lizards, insects and other species to evolve – and most can't keep up"
Some species have been able to meet the challenge with rapid evolutionary adaptation and other changes in behavior or physiology. Dark-colored dragonflies are getting paler in order to reduce the amount of heat they absorb from the sun. Mustard plants are flowering earlier to take advantage of earlier snowmelt. Lizards are becoming more cold-tolerant to handle the extreme variability of our new climate.
However, scientific studies show that climate change is occurring much faster than species are changing.
And, perhaps, some positive news:
"Company attempts to harness ‘forgotten, renewable energy source’ in the ocean — but major questions remain"
And while the process, called ocean thermal energy conversion (OTEC), has to this point been too expensive to sustain in other attempts over the years, leaders of the venture Global OTEC feel that innovations have advanced enough for another try at the intriguing concept. The effort is geared toward harnessing a “forgotten renewable energy source,” according to a Global OTEC press release.

"Another Record-Hot Month Puts 2023 on Track to Be Hottest Year Ever"
Interesting chart. I expect weather to become increasingly "interesting" in the next few years.

"Current carbon dioxide levels last seen 14 million years ago"
Published in the journal Science, the paper covers the period from 66 million years ago until the present, analyzing biological and geochemical signatures from the deep past to reconstruct the historic CO2 record with greater precision than ever before.
"It really brings it home to us that what we are doing is very, very unusual in Earth's history," lead author Baerbel Hoenisch of the Columbia Climate School's Lamont-Doherty Earth Observatory told AFP.
Among other things, the new analysis finds the last time the air contained 420 parts per million (ppm) of carbon dioxide was between 14-16 million years ago, when there was no ice in Greenland and the ancestors of humans were just transitioning from forests to grasslands.
That is far further back in time than the 3-5 million years that prior analyses have indicated.
Until the late 1700s, atmospheric carbon dioxide was about 280 ppm, meaning humans have already caused an increase of about 50 percent of the greenhouse gas, which traps heat in the atmosphere and has warmed the planet by 1.2 degrees Celsius compared to before industrialization.
