I once wanted to make funny comics to make people laugh and distract them from the troubles of the world. Now I want to draw attention to them.

Moving planetary sunshade systems (PSS) from conceptual proposals towards practical engineering requires detailed assessment of their architecture, scalability and controllability.
This paper presents a Model-Based Systems Engineering (MBSE) framework for evaluating modular PSS designs, linking mission objectives and requirements to configuration-specific sizing, subsystem analysis and quantitative feasibility measures.
The approach is demonstrated through a representative precursor mission, covering preliminary system sizing, attitude and orbital control torque requirements, actuator feasibility, subsystem selection, and mass, power and communication budgets.
Requirements are connected to their corresponding design and analysis outputs, allowing assumptions and sizing decisions to be traced and updated through future iterations. The application provides an initial quantitative feasibility assessment within the assumptions adopted for the demonstrator.
The framework offers a structured route from high-level sunshade concepts to configuration-level technical evaluation, while identifying engineering challenges requiring further investigation in future mission studies and digital-twin development.

Three years ago, our 2023 @DrJamesEHansen et al. paper, “Global warming in the pipeline”was published.
Earth’s Energy Imbalance has continued to increase, and most of the 463 citations support our findings.
The world needs to prepare for a rapidly changing planet.
Today we presented the 'Warming in the pipeline' paper, lead by @DrJamesEHansen.
The recording of the press conference is available here.
At 34:30 min, I explain the effects of sulphur emission changes, notably from shipping, of accelerating warming:

New laboratory measurements provide infrared optical data for calcite, a candidate aerosol material being investigated for stratospheric aerosol injection (#SAI) and other solar radiation modification approaches.
Researchers measured absorption spectra from nano-sized (50–120 nm) and coarser (200–750 nm) calcite particles, alongside extinction spectra from airborne calcite aerosols spanning 30–2,000 nm.
Measurements used Fourier transform infrared spectroscopy across several sample preparations and techniques, including transmission, aerosol extinction and attenuated total reflectance.
The team also characterised particle crystallinity and morphology using powder X-ray diffraction and electron microscopy, and measured the infrared spectrum of aragonite, a less stable calcium carbonate polymorph that commonly occurs as an impurity in calcite.
The results are compared with calcite optical data previously used in climate modelling, including measurements obtained through spectral reflection. These new measurements are intended to improve the optical inputs used in radiative transfer models assessing the climate effects of calcite aerosols.

Proud to announce my next book "Remaking Eden: The Science of Reversing Climate Change" will be published by @doubledaybooks in 2028. Writing it forced me to think more clearly than ever about the awkward politics of climate engineering. Can't wait to share it.

Last night Trump said he could have won Vietnam in a week. His plan was “going after Ho Chi Minh City.”
Ho Chi Minh City was Saigon, the capital of South Vietnam. Our ally. The enemy’s capital was Hanoi. We bombed it.
He called the presidents who fought that war stupid, then explained how he’d have won it by attacking our own side.
58,220 Americans died in that war. Trump got five deferments. Now he’s telling the rest of us how easy it would have been.
He’s had more than fifty years to learn which side we were on. He still hasn’t. That alone should disqualify him from sending anybody else’s kids to war.
Instead, he’s weighing more strikes on Iran after Tuesday. His administration has reportedly considered using the “mother of all bombs,” the one he calls “like a tiny nuclear bomb.”
The man who thinks we should have bombed our ally’s capital gets to choose the targets.

The ocean absorbs around 30 per cent of human-caused carbon dioxide (CO₂) emissions and 90 per cent of excess heat trapped by greenhouse gases. But climate change has already reduced its capacity to absorb carbon by approximately six per cent, a new UN...

ALT Climate Change Is Accelerating Faster Than We Can Respond, Scientists Warn
BROKEN: mass media editors publish article revealing humans can't respond to accelerating global warming but refuse to mention billions will likely die due to capitalist era policies and then move on to the next story as if nothing happened
ALT The researchers warn that the rate of global warming appears to have accelerated, from about 0.05°C per decade between 1880 and 1970 to roughly 0.36°C per decade between 2010 and 2024—and the 2°C threshold meant to limit planetary damage could be reached before 2050 they warn. These accelerating and intensifying changes could raise the risk of reinforcing feedback loops and crossing tipping points—critical thresholds that, when crossed, can lead to accelerating and often irreversible environmental changes. In 2025, the Earth passed its first climate tipping point, as rising ocean temperatures, acidification, overfishing, and pollution are combining to cause coral bleaching and mortality. "Earth’s life-support systems are being pushed beyond stable limits," the report states, "with changes unfolding faster than our ability to respond."

I was interviewed about how my assessment of climate & climate science in 2018 has sadly turned out to be closer to reality than the consensus science at that time, and, crucially, what to learn from that youtu.be/R3pVSUwY7Ok?si=2J4M…

To be clear, the greenhouse gas forcing is different from Earth's Energy Imbalance, as the Imbalance is a result of all forcings, feedbacks en natural variability.

Andreas Malm's "Fossil Capital" is indispensable reading for anyone who wants to understand the roots of the planetary crisis.
Andreas Malm has been banned from entering the UK.
The Swedish climate scholar was due to speak in London next week at the launch event for Tribune’s latest issue.
The Home Office said that Malm’s presence in the UK was considered not to be ‘conducive to the public good’.
It’s the latest example of the Labour government banning leftist and pro-Palestine figures from entering the country.

Nothing beats the horrors that will come from this anthropogenic greenhouse gas forcing.
The heating from a greenhouse gas forcing of 4.2 W/m² is equivalent to more than a billion Hiroshima bombs per year.

The Ocean Cleanup is now $40M/year short of what’s needed to stop up to 1/3rd of all plastic flowing into the oceans by 2030.
That’s less than 1% of what America spends on Halloween decorations each year.

People are dying from heat right now, and the answer is still “we need more research.”
What the fuck is all the research we already have for, then?
There’s an entire body of work on stratospheric aerosol injection. At some point, we have to use it to make a decision. My position is that we should move toward gradual, closely monitored deployment and adjust based on what we measure. Keep researching while we do it.
That involves risk. So does letting the planet keep warming while we argue. You don’t get to demand perfect certainty from an intervention and then treat waiting as harmless.
What would actually be enough evidence for you? What result would make you willing to act? If you can’t answer that, “more research” is just a way to avoid making a decision.
I’m fucking tired of hearing that this is an emergency from people whose plan has no point at which we actually start cooling anything.
