HPAC Forum this week: Ocean Pasture Restoration with Russ George

[rob...@rtulip.net]

Please join the Healthy Planet Action Coalition this Thursday, 2 October at 5.30 pm Eastern Time, for a conversation with Russ George on Ocean Pasture Restoration.

 

Link is https://us02web.zoom.us/j/88954851189?pwd=2OEdvleb4UpYfK4a950ryohFWcw93F.1 (passcode 662519). 

 

The meeting will go for up to 90 minutes.  Thursday 5.30 pm Eastern = 10.30pm UK = 7.30 am Friday Australia AEST

 

In 2012, Russ George worked with the Haida Salmon Restoration Corporation in British Columbia to add iron to the waters of the North Pacific Ocean at the point where salmon fingerlings most needed food. The project encountered criticism from scientific and environmental organisations and media. 

 

Russ will share his perspective on the science and politics of ocean replenishment and restoration and its potential role in climate cooling and fisheries enhancement. His presentation will be followed by open discussion.  Russ’s website is https://russgeorge.net/

 

Regards

Thanks, Robert, I’ve now had a chance to listen to Russ George’s talk.

 

Only one comment, the claim that glassy volcanic ash from explosions is completely insoluble is the opposite of the facts.

 

Glass is metastable, and dissolves much more rapidly than crystalline minerals both because of higher surface area and because thermodynamic instability promotes rapid dissolution.

 

For example glassy amorphous silica from diatom oozes is used on soils because it dissolves around 10 times faster than silica in quartz.

 

The same is true of the finely divided amorphous metastable iron minerals.

 

In fact it is very easy to grow very fine amorphous iron in both oxidized and reduced form in the ocean, but the question is if the other essential elements are present in the necessary ratios.

[Garrity, Dennis]

Please join our next Healthy Planet Action Coalition meeting this Thursday,  October 16^th at 5.30 pm Eastern Time, for a Town Hall conversation on the just-concluded HPAC online conference on The Global Heating Emergency. Preventing 2 degrees by 2040: What’s the Plan?

 

We’ll be discussing how to build on the conference toward the next phase of action to intensify our impact on the global stage.

[rob de laet]

Hello everybody, 

Congratulations on pulling off such an amazing conference and I think this will have a ripple effect into this world. In a crisis of this magnitude we need all the tools at our disposal to cool the climate. I am not involved enough to judge the different SRM techniques that have been proposed, but I like to repeat that according to our calculations natural SRM by increasing cloud cover through restoring the rainforests can have a considerable effect. If the Amazon rainforest were fully restored, the resulting increase in low cloud cover could boost regional albedo enough to reduce the planet’s energy imbalance by up to ~0.15 W/m², cutting today’s global heating rate by around 10%. This is apart from surface cooling through increased evapotranspiration and latent heat radiation out into space at condensation at cloud level. The Amazon is about 40% of remaining rainforests, all together, the restoration of tropical rainforests can have a crucial cooling impact. 

The 2023 drought over the Congo and Amazon and adjacent ocean areas give evidence of these huge impacts.

Hope this helps as part of the total solution, 

Kind regards,

[Ron Baiman]

(Cross thread post) Followup to our discussion last night (for more extensive discussion see the Oct 8, 2025 "How Climate Intervention can Safely and Quickly Cool the Planet_HPAC NYC Climate Week_Sep. 26, 2025" HPAC thread):

Dear Colleagues,

Good discussion to which of course I can't help but add a few points!

First, I sympathize with Alan's concern over excessively absolute standards for governance before deployment in light of the risk-risk tradeoff that we are facing. My thinking is that,  per the governance discussion in the "challenges and opportunity" section  of the HPAC cooling paper (see: https://academic.oup.com/oocc/article/4/1/kgae014/7731760 ), in a situation where not deploying global cooling asap will without a doubt lead to greater warming and longer overshoot and thus greater calamity for humans and other living species, as in war war-time decision making, we need to have a more evolutionary symbiotic view of the relationship between governance and deployment (and governance and field testing) that specifically challenges the now dominant position stressing multiple absolute hurdles of social acceptance and governance that must be in place before piloting SAI or indeed even doing small-scale outdoor experiments with this in mind. Here's a powerpoint summarizing this view (that is in our paper) that I presented at an HPAC meeting some time ago: https://docs.google.com/presentation/d/1mQed7U89TEjOWi31rTGwaubg0vpk-SzK/edit?usp=sharing&ouid=116465941111195452408&rtpof=true&sd=true 

See also slide 9 of this (slightly updated - in red) powerpoint for my presentation of the Abstract that I, Mike and Greg submitted on behalf of the UR WG to SAI workshop: https://docs.google.com/presentation/d/1bNkZVjYBBS1ljhcY7RFVdnsikmjmCWw9/edit?usp=sharing&ouid=116465941111195452408&rtpof=true&sd=true

Second, relevant to this (and a point that I've been trying to convey in various fora) is Mike's recent observation (I think I'm correctly describing his thinking on this - and cc'ing him just in case!)  that as we know that SAI works (volcanoes have been doing it through geological history) and given the urgent need to cool, our focus should now be on "engineering optimization" that can only really only be done through piloting and real in-situ experimentation to reduce and (hopefully) work around known known possible adverse side effects (from modeling none are catastrophic) and possible unknown (from modeling) adverse impacts, and expand benefits as much as possible. This view I think makes clear that, though more research is always better, the priority now needs to be practical deployment focused testing and gradual scaling. 

Third, I am also sympathetic to Alan's reasoning with regard to China that (in a much more thought out and careful way) expands on discussions that I have had with regard to a geopolitical self-interest based SAI deployment that might be initiated by a political leadership with longer time horizons than are typical in a democracy. In this sense the issue is not only whether we can cool quickly but also whether the very hard fought and difficult to sustain accomplishment of democratic constitutional governance can survive this particular leadership and capacity test as it did the fight against facism.  

Finally, Herb and I have long disagreed over what can be considered (if anything) HPAC's official "mission statement". My reading is that HPAC now has in fact multiple different mission statements produced at different points in time for different purposes that broadly agree on promoting (differently nuanced versions) of the climate Triad as our core mission. 

Best,

Ron

Bruce Parker will present an in-depth review of the data and assumptions behind his recent talk, “The Impact of CO2 Emission Mitigation and Removal Strategies,” delivered at HPAC’s “The Global Heating Emergency” conference earlier this month.

 

He has developed a practical formula that anyone can use to forecast the expected rise in global temperature over the next few decades. It is based primarily on projected CO2 emissions and anticipated changes in the Earth’s albedo.

 

He will also demonstrate that carbon dioxide removal efforts are likely to have only a negligible effect on the projected 2040 temperature increase.

Hi Bruce and Dennis, 

thank you for this announcement. I think we are all aware  ''that carbon dioxide removal efforts are likely to have only a negligible effect on the projected 2040 temperature increase.'' The world will not change its mind on this subject fast, so we can use carbon money to finance more effective solutions that sequester carbon as a bonus. Will we spend time on solutions, such as the invigoration of the atmospheric watercycles by strategically restoring the biosphere such as I propose? 

Thank you,

[rob...@rtulip.net]

Here is a temporary recording of today’s HPAC meeting with Bruce Parker assessing potential heat impacts of carbon action. 

 

This is an excellent discussion, quantifying estimated temperature effect of carbon emission and removal strategies over coming decades, and comparing to action on albedo.

 

The message I took from this analysis was that nothing we do about carbon can affect climate in the next decade, and the main policy focus has to switch to sunlight reflection to minimise the major disruption of the coming Earth fever.  Of course carbon action remains vital, but its short term benefits are more in economics and environment, not climate.

 

Lucinda and Ron, please upload to HPAC website.

[Rebecca personal em]

Hello all,

Thanks for a very valuable meeting today, and I am happy to work on the slides with you Bruce when you add a narrative.

The main policy conclusion I get is that we need to communicate “net zero is not enough and there are options to cool which can reverse and prevent 2 degrees”.  that’s the first step and then we have this detailed analysis up our sleeves.

Warmly to all,

Rebecca
