The published work shows a stairstep progression with large amounts of heat being released from the ocean to the atmosphere during el nino. This is not a ,'driver' per se, but heat movement. Changes in ocean surface wind patterns may lead to increases warming rates in the future

The last time we had CO2 levels anywhere near todsy's values the ancient Sonoran Desert stretched all the way up to central Nebraska.

Hi bob, it is so good of you and to see the good of you in your posting. Thank you!

When that multidecade negative trend caused by stack land based aerosols flips to a near continuous positive PDO and correlates to a strong El Nino we will see our first 6 months of GMST at >2.0C

When a tree becomes diseased it overproduces flowers and seeds to pass on new life before it dies. Humanity's sole purpose was to create new AI and now it will finish the job.

The world's largest sand battery just went live in Finland Finland has inaugurated an industrial-scale sand battery this week in the southern town of Pornainen, where it'll take over heating duties from an old woodchip power plant for the municipality. It's s...

Sand batteries are literally just silos of sand that retain heat exceptionally well -- so well that they can be tied to heat exchange systems to serve as proxy *electrical* batteries. Finland's new model can store enough power (100 MWh) to heat an entire town for a week.

Our solarpunk present is shaping up to be a weird mix of thermopunk, electropunk, and cyberpunk (derogatory).

4.6 Billion Years On, the Sun Is Having a Moment In the past two years, without much notice, solar power has begun to truly transform the world’s energy system.

Globally, roughly a third more power is being generated from the sun this spring than last. If this exponential rate of growth can continue, we will soon live in a very different world, @billmckibben.bsky.social‬ writes.

Time series of global annual average temperature anomalies from 1850 to 2024, and the projected range for 2025.

Time series of global annual average temperature anomalies from 1850 to 2024, and the projected range for 2025.

Following a relatively cool May, the odds of 2025 being warm enough to set a new annual record have fallen to only 5.8%.

More likely, 2025 will become either then 2nd or 3rd warmest year on record.

How Soon Should Companies Prepare for a 2°C World? The WMO warns global temperatures could rise 2°C by 2030. The findings should push companies to take a hard look at how prepared they are.

The @wmo-global.bsky.social latest report is a stark warning: we're nearing 2°C warming by 2030, with alarming predictions for the next 5 years. Our Prof. @soniaseneviratne.bsky.social calls it a "climate emergency." (...) which, among other crises, we shouldn't forget.

I have long posited this as a "third forcing feedback" associated with aerosol emission reduction. Have a long bet with zeke hausfather on it. Weak but large area impacts not localized to shipping lanes.

They don't take into account non-shipping lane sulphate reductions on surface winds.

Drivers of the extreme North Atlantic marine heatwave during 2023 - Nature Atmospheric reanalyses combined with ocean observations and model simulations show that the extreme 2023 North Atlantic heatwave was primarily driven by anomalously weak winds leading to strongly shoa...

Looks like we finally have an explanation for why the Atlantic (and, by extension, the Earth) was so warm of 2023. From Matt England et al.
