It also raises the question who is made 'famous' and why.

Some treat this more as a pissing contest rather than an honest debate about what the data shows.

Based on the NASA CERES data (used for the Hansen et al. climate sensitivity estimates), the current rate of heat uptake (and the relative fluxes) are at the very edge of CMIP6/IPCC estimates.

If the NASA satellite data is correct, the IPCC best estimate and resulting carbon budgets etc are wrong

"Many scientists agree that the rate at which it is increasing has picked up.

This is mainly because of a reduction in air pollution following the introduction of fuel regulations for international shipping "

He lies about and smears anyone who takes an honest look at the actual data.

Let alone those who call him out on his disinformation spreading.

I understand why many want to avoid his wrath.

He publicly denies acceleration of global warming, while research he coauthors confirms it.

What he calls an 'indefensible' and 'ad hoc method' (correcting for natural variability) was already published in 2011 and has been cited 359 times:

Everyone who's ever published a scientific paper knows that many professors don't even bother to read papers they slap their names on.

It's either that or fraud and gross negligence.

Not sure which is worse

This is what new age climate change denial looks like.

The truth is that some can't help themselves to keep digging, even while putting their names on papers comfirming acceleration of global warming and the contributing factors of reducing aerosols and continued greenhouse gas emissions.

"In case of a linear evolution, that corresponds to the mid‐point of the 20‐year period defined by IPCC as 1.5Β°C threshold. According to this, all data sets are near 1.5Β°C already and will cross that limit before 2030."

We (e.g. Global warming in the pipeline, Hansen et al. 2023, 2022 preprint) have been warning for years.

The larger modeling community still underestimates the rate of warming, mainly because of faulty assumptions on aerosols.

It's good to have more observations based reseach.

Global Warming Has Accelerated Significantly
Foster & @rahmstorf.bsky.social

"The resulting adjusted and thus less β€œnoisy” data show that there has been acceleration with over 98% confidence, with faster warming over the last 10+ years than during any previous decade."

Nothing good about the Trump administration, but it will probably be hard to see the increase in this graph.

2025 data quietly released by EPA shows harmful increases in dangerous air pollution attributable to Trump, personally, with 6 TX power plants that Trump exempted from stronger safeguards, for example, experiencing an astonishing 48% increase in sulfur-dioxide emissions collectively in 2025. 1/
