Thank you Renaud!  I hope you don't mind my distributing this more broadly as I think it's quite important!

Best,

Yes, but we are seeing what may turn out to be 2023 extreme heat events only just starting to develop.

 

A measure of extreme ocean heat stress is the Coral Bleaching HotSpot map, showing areas more than 1 degree C above the historical averages for the warmest month of the year (yellow areas are at threat of coral bleaching)  (Goreau & Hayes, 2021).

 

At the moment, extreme surface heat is focused on equatorial waters far from coral reefs, and the Northeast Atlantic:

 

 

But the Northern Hemisphere summer is only rapidly starting, and equatorial heat is rapidly being transported towards the North Polar regions, below is the latest rate of surface ocean warming, ocean surface heat is headed for the Arctic!

 

Be warned: All this will change rapidly when we enter a full El Niño!

Hello Maiken

 

I had not heard of Last Generation but we have equivalent groups in Australia. I found a report on German government crackdown on last generation disruptive protests at https://earth.org/last-generation-activists/.

 

Such groups mean well but lack coherent strategic vision of how to prevent dangerous warming and are often unwilling to engage in courteous dialogue.  They wrongly imagine that shutting down fossil fuel industries as fast as possible is the best way to respond to climate change.  This is a popular line on the political left, but it is a futile and incorrect ideology that sets back efforts to improve public understanding of climate science.

 

Cutting emissions is marginal to the immediate climate situation, given the high risk of tipping points which can only be mitigated by albedo enhancement.  As well, the inertia in the fossil fuel economy means it has the power and interest to ignore climate science.  Improving the GHG situation is only possible in the long term.  Trying to accelerate emission reduction creates division and antagonism while achieving nothing for actual cooling. By contrast, albedo enhancement can support commercial and community interests in political and economic and environmental stability and security.

 

It is important not to subordinate climate policy to the old fashioned socialist idea that building a popular front of progressive forces is the only way to achieve change.  Climate stability and repair can be achieved through negotiation across partisan lines to gain broad support for net zero heating as a policy goal.  That will require intergovernmental support for sound governance of measures to increase planetary albedo.

 

Regards

 

Robert Tulip

Hi dear all,

may I ask you... since all the writing and talking didn't help and we are now close to the irreversible tipping points we know about for years...what's your opinion about Science Rebellion and the Last Generation? Do you consider to also become part of this movement (as I am)?

It's horrible that we are so far into this catastrophe that even I blockade streets.

Best,

Maiken

Hi Maiken,

If you study the websites of Scientists Rebellion (SR) and Extinction Rebellion (XR) you will see a vague and almost incoherent analysis of the dilemma that we are in and the necessary actions to get out of it. 

SR speaks of the need for decarbonization at the required scale, whatever in the world that means. It also demands degrowth with the rich to pay for degrowth, however in the world that would work.  

Extinction Rebellion has a number of a long-standing demands articulated as far back as 2018. They call for governments to tell the truth, for citizen assemblies to be created by governments to essentially take over the decision making process and for net zero by 2025.  

XR  is essentially violating its own first demand to tell the truth in calling for decarbonization in two years. (when they first called for decarbonization in 2018 at least there was the longshot possibility of getting close to zero in less than a decade with emergency scale action.) 

There is of course no conceivable pathway to decarbonize in two years without total planetary economic collapse, poverty, chaos, and death.  Yet they have yet to modify or drop the demand. 

Neither SR or XR appear to even demand carbon removal, much less direct Climate cooling as Robert indicated. 

I have had conversations with numerous people in XR in the US and the UK over the years (I marched in two of the major XR actions in London several years ago) to no avail. 

Paradoxically while they highlight the term rebellion in their very titles, they refuse to date to accept any climate remedies except the mainstream ERA model - emission reductions alone. Thus they refuse to challenge the increasingly flawed paradigm that governs planetary climate action. What kind of rebellion is that?

 I expect to have an opportunity to speak with one of XR’s most prominent public leaders who expressed interest in cooling before too long, and I’m keeping my fingers crossed that there will finally be greater receptivity to a broad based climate triad approach. 

I’m not familiar with Last Generation. 

Hope this helps.

Dear Colleagues,

In relation the last sentence in the excerpt from a quote in the Guardian piece that Chris shared:

"Piers Forster, a professor of climate physics at the University of Leeds, said: “Both Met Office and NOAA analyses of sea-surface temperature show temperatures are at their highest ever level – and the average sea-surface temperature breached 21C for the first time in April. These high temperatures are mainly driven by unprecedented high rates of human-induced warming.

“Cleaning up sulphur from marine shipping fuels is probably adding to the greenhouse gas driven warming.  ...  "

A bunch of us (in forums and communications within the groups in the lists above) have been discussing a potential immediate practical step (that earlier has been raised by others) that may provide at least a modicum of cooling especially over the oceans: a relaxation of the "bunker fuel" sulfur content regulations that just came into effect in 2020 (https://www.theguardian.com/environment/2020/jan/01/shipping-fuel-regulation-to-cut-sulphur-levels-comes-into-force ) for inter-port "high seas" shipping. The idea is that cargo ships and tankers would be able to use the old dirty sulfur laden fuel in the open ocean but switch to the cleaner fuel when they are near ports or human habitation. Apparently many ships have multiple fuel tanks so that they may be able to switch fuels in transit.

To be clear, we would stress that we fully support getting off of fossil fuels, but if fossil fuels are going to be used anyway it makes no sense not to at least benefit from fossil fuel burning maritime sulfur aerosol generation that is known to have a significant cooling effect (how much is currently being re-estimated using the "termination shock" signal from the 2020 abrupt change in sulfur emissions due to the regulation).  Looking forward this also points the way to including effective (and hopefully less harmful to human health) tropospheric aerosol generators in future non GHG emitting replacements for the bunker fuel (see the HPAC direct climate cooling petition for some possible options: https://drive.google.com/file/d/1yHe2Fe6fU11odfcH-4GwdYDNTCk7uB-J/view?usp=sharing ). 

Any thoughts or data on this that might be helpful in working up (or not) this proposal would be appreciated.  I will repost under a separate heading to better publicize and solicit feedback.

Best,

Ron
