Thanks for noticing my typo.

MHS stands for 'Marine heat spikes', but this isn't a spike anymore.
The increased stratification and relative shallow Straight of Gibraltar might cause the anomalously high sea surface temperatures to become permanent faster than most thought possible.

2025 has been above the MHS level almost constantly this year..

Besides the 'Doomer strawmann', there are the following:
-'Instant net-zero strawmann', for those who want to keep 1.5 alive.
-'It's just political strawmann', for those who want to pretend existing infrastructure is not part of our physical reality.
-'Natural variability strawmann', 👇

That's officially how it's spelled.

It often reads something like this.
It's done to avoid confusion between forcings and feedbacks, but it impacts ocean based aerosols much more than other forcings.
This question will keep a lot of scientists busy, but most people won't care if it's a forcing or feedback heating their oceans

And cloud feedbacks from higher surface temperatures leading to more absorbed sunlight.
Until a new balance is reached.
This is one of the many reasons why aerosols over the oceans have stronger effects than the same aerosols over land.
Most climate models don't take that into account.

Kids love to learn.
And can learn fast when offered the right information in a fun and engaging manner.
Our kids have been learning and dancing to this song in school, for example:

Just imagine an oncologist calling all their anxious patients doomers...
The problem is that we don't really have many doctors for the climate.
Mainly highly specialized academics and ill-informed opinionators (with a few notable exemptions).

I just can't comprehend how someone could respond with an extensive 'doomer definition list' to a question about climate anxiety.
It's utterly tone deaf.
Who can take an honest look at the rate of climate change and not be anxious about the impacts?
An anxious realist is not a doomer.

Sulphur rains out within days or weeks, but it takes a lot of heat to warm the oceans.
So we'll need a few years of data to see the signal from the noise.

Thanks for resurfacing this.

Close to where we live, Pieter Harting discovered that the land was once covered by sea, harboring life now found in the warm waters of the Mediterranean.
He named the Eemian interglacial.
We have known that our climate can change for over 150 years and are now creating a super interglacial.

I have 'disdain' for those who constantly use the doomer strawmann to downplay how bad it really is.

Climate science communication is the most toxic environment I've ever worked in.
Fossil fuel peddling climate deniers on the right and prestige seeking environmentalists on the left, all constantly using ad hominems and strawmann arguments.
Few seem to care about what the data actually shows.

'all models have a weaker trend than the observed [NASA 🛰] trend'
'The most notable result is that the CERES data show a higher SW [shortwave = increased aborbed sunlight] EEI [Earth's Energy Imbalance] trend per degree warming than any of the CMIP6 models'

Yes, there are a lot of false hope blogs taken as gospel.

It's not just about emissions.
It's also about how the climate responds to those emissions.
Less aerosols and stronger biosphere feedbacks (mainly methane and COâ‚‚ increasing faster than in models) causes a stronger climate impact

For some reason the tag is deleted but the post isn't?
I've never seen this before.
Does pointing out that there's no scientific evidence for us staying below 3°C make me a doomer?
Such a bad strawmann argument.
comment in response to

I haven't seen a single peer reviewed paper backing up the <3°C statements.
Just some blog posts that many take as gospel

The trust in climate models will crumble more and more as reality plays out.
Global surface air temperatures vary a lot and alone are a bad indicator, as every climate scientist worth their salt knows.

I think we have different definitions of progress.
'Less bad than some worst case emission scenarios' isn't progress in my book.
The discussion was about staying below 3°C of global warming, for which no one has provided any scientific evidence, just social media and blog posts.

It's not about feelings.
It's about adapting to a rapidly changing climate effectively.
When climate models underestimate regional climate change, the adaptation plans will not suffice.
