Seemingly comprehensive and accurate in the listing of observations, but shallow and dogmatic in solutions, samo samo bunk.

A few keyword searches reveal zero mention of just about everything PRAG, HPAC, HCA, CDR, et al. discuss daily.

Irresponsible, but they have the loudest megaphone.

Disgusting!

Hi Doug

 

Thanks very much for sharing this 2025 state of the climate report (link).  It provides an excellent overview of the accelerating crisis, but as you indicate, its analysis of what to do about it is hopeless and highly politicised.

 

The paper opens with a discussion of Vital Signs, stating “The last few years have seen … [heat] records broken by extraordinary margins …  consistent with warming accelerating because of a large cloud feedback and decreasing emissions of aerosols”, endorsing James Hansen’s assessment that cloud and aerosol loss are primary drivers of warming. 

 

Extraordinarily, it then totally fails to recognise the extensive research on activities to mitigate these problems by restoring planetary albedo.  It is deeply troubling how leading scientists feel they can recognise the most important causes of warming, and then proceed, as you say, to snub these elephants in the room.  This strategy is consistent with the ad hominem approach to Hansen’s research adopted by prominent media climate commentators such as Michael Mann, one of the report co-authors.

 

The section on page 5 titled Energy Balance, together with the excellent graph 2n, showing that annual mean albedo has fallen by 2.1% since 2000 (29.3/28.7%), reveal that the drivers of warming far exceed the capacity of the solutions they propose to rein in the Earth fever.  No feasible carbon action can slow the darkening of the Earth, so the restriction of response to carbon is a futile and delusional strategy. 

 

Their claim that there are “proven strategies” to support transformative changes is just rhetoric.  Darkening will swamp these efforts unless sunlight reflection becomes the main climate strategy.

 

I suspect some co-authors such as Michael Mann would have exercised a political veto on any mention of solar geoengineering, which is totally absent from this bizarre document.  It would be better if sensible authors rejected this bullying and stopped their subservience to such harmful and stupid views.

 

Regards

No one following the discourse amongst climate scientists can be at all surprised that direct climate cooling remains verboten in this and virtually every other paper article or communication. 

While Michael Mann is clearly in support of SRM research he interprets the research as making deployment unacceptable. 

Johan Rockstrom, another of the co-authors is - along with Jim Hansen, Michael Mann and Katherine Hayhoe - the best known and highest profile climate scientist communicator in the Western world. 

Johan is a world leading researcher on planetary boundaries and tipping points. 

Yet he answered with an emphatic and unambiguous no to the question I asked him about whether he supports solar Geo engineering in my interview with him during the Exeter Global Tipping Points Conference - an answer that surprised me in its finality. 

As far as I can tell this is the first time in recent years that he was put on the record regarding his views on SRM. 

See https://youtu.be/tG-hh-gSKFQ at a 15 minute mark. 

Nowhere in the paper did I see a definitive quantitative and qualitative description of what life would be like at mid century even with substantial if not complete decarbonization. 

All of these esteemed authors chose as they almost always do to avoid stating what is in my opinion the most alarming conclusion of mainstream science. 

Which is that the climate will not improve it will only continue to worsen even after NetZero and will remain at a level inconsistent with organized civilization for centuries. In other words even the most aggressive and utopian versions of successful decarbonization will still inevitably lead to a world that no one would choose to live in. 

Thus I wholeheartedly agree with Doug and Robert. 

This paper by choosing to avoid any mention of the possibility of cooling the planet paints a picture of a future that would make the word dystopia seem like a walk in the woods on a beautiful spring afternoon.

In review:

The Physics of Collapse: Global Warming as a Slow-Motion Disaster

Global warming is different from other natural disasters in that it has developed gradually over the past two centuries and now affects every region of our planet. Unlike sudden events like storms or earthquakes, global warming is a long-term problem that is accelerating. As the climate changes, the Earth’s energy imbalance increases, exposing new environmental issues and new types of disasters. Scientists view global warming as a prolonged energy crisis for Earth, characterized by rising temperatures that disrupt the atmosphere, oceans, and living organisms. Most of this heat, about 90%, ends up in the oceans, raising sea temperatures, causing the water to expand, and leading to more extreme weather. This constant overload acts like a machine running hot. Instead of one big disaster, it causes ongoing problems and breakdowns. The changes in temperature, chemistry, and water cycles last much longer than most disasters, making it hard to know when the crisis ends or when a new normal begins. Human activity is the main cause of this problem. By altering the atmosphere's composition and disrupting natural systems, mankind has become a major force shaping the planet. We need to see global warming as more than just an environmental problem; it is a global emergency. To mitigate the damage, we have to restore the Earth's energy balance. Simply adapting or rebuilding after climate damage isn’t enough. The extra heat of warming presents an opportunity to improve our systems, rather than just a threat. It can provide a sustainable and prosperous future.
