We are done for as there is no emerging means or coalition to stop and reverse anthropogenic climate change.

Earth barreling toward 'Hothouse' state not seen in 50 million years, epic new climate record shows

Record goes back to the dinosaur extinction.

Sixty-six million years ago, after a massive asteroid hit Earth with the explosive energy of roughly 1 billion nuclear bombs, a shroud of ash, dust and vaporized rock covered the sky and slowly rained down on the planet. As plant and animal species died en masse, tiny undersea amoebas called forams continued to reproduce, building sturdy shells out of calcium and other deep-sea minerals, just as they had for hundreds of millions of years. When each foram inevitably died — pulverized into seabed sediment — they kept a little piece of Earth's ancient history alive in their fossilized shells.
For decades, scientists have studied those shells, finding clues about the ancient Earth's ocean temperatures, its carbon budget and the composition of minerals spilling through the air and seas. Now, in a new study published today (Sept. 10) in the journal Science, researchers have analyzed the chemical elements in thousands of foram samples to build the most detailed climate record of Earth ever — and it reveals just how dire our current climate situation is.
The new paper, which comprises decades of deep-ocean drilling missions into a single record, details Earth's climate swings across the entire Cenozoic era — the 66 million-year period that began with the death of the dinosaurs and extends to the present epoch of human-induced climate change. The results show how Earth transitioned through four distinct climate states — dubbed the Warmhouse, Hothouse, Coolhouse and Icehouse states — in response to changes in the planet's orbit, greenhouse gas levels and the extent of polar ice sheets.

The zig-zagging chart (shown above) ends with a sobering peak. According to the researchers, the current pace of anthropogenic global warming far exceeds the natural climate fluctuations seen at any other point in the Cenozoic era, and has the potential to hyper-drive our planet out of a long icehouse phase into a searing hothouse state.
"Now that we have succeeded in capturing the natural climate variability, we can see that the projected anthropogenic warming will be much greater than that," study co-author James Zachos, professor of Earth and planetary sciences at the University of California, Santa Cruz, said in a statement. "The Intergovernmental Panel on Climate Change (IPCC) projections for 2300 in the 'business-as-usual' scenario will potentially bring global temperature to a level the planet has not seen in 50 million years." (The IPCC is a United Nations group that assesses the science, risks and impacts of climate change on the planet.) ...

Renewable energy is displacing coal/oil/gas in energy production, EVs are shouldering FF cars off the road.

It won’t be that bad. Still a ton more to do but economics is now in favor of clean energy and clean transportation.

I do not like wailing about doom when doom will not hit us but future generations.

The same people crying doom from AGW go to water when the nuclear option is mentioned.

There are some trends that are good, follow those. Even crap as weak as replacing all lights with LED lights helps, esp if you get a few mates to do so too—the motivation is there, much lower electricity bills: there is a 15W light in the lounge, brighter than 2 x 120W incandescents..

Bit bigger—solar panels on your roof. Bit longer but very solid $ gains for doing so. I want windmills as well—long Tassie winters with shorter days than Adelaide, more clouds as is 50% wetter too. What about some external blinds/awnings? A deciduous tree on the northern side of the house?

Selling your energy guzzler house and lifestyle and buying a cave also works.

Here's a cave with a pool:

I simply cannot believe this year took over 2007 and 2016,... like I still can't believe 2019 got anywhere near them either...

That high pressure over the CAB in July(!?) was the weather phenomenon that changed it all this year, apparently, going by the internet chatter. In 2012 it was a mega cyclone and in 2020 it was a lengthy high pressure zone over the North Pole itself at time of maximum insolation... truth really is stranger than fiction it would seem!

:hiding:applause:applause:applause:applause:applause:genie

This could get interesting very quickly...

Checkout out Kara, ESS and Laptev Seas............ Laptev this year was a record low, half of second place: second place was ten times less than third place....

I think I've already said this but it still spins me out...

(Something is afoot, ...or is it amiss? :scare :jawdrop:jawdrop:jawdrop:jawdrop:jawdrop:jawdrop:jawdrop:jawdrop:jawdrop :monkey winks)

Extent doesn't exactly translate to volume so,... data is data!

Trends and relationships certainly exist but exact statistics don't always correlate because they are, strictly speaking, measuring different things... and those things have their own error values!!

Your voluminous pontifications point to a softening of the peter heater market.
