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/

Robert Tulip

There are many memorable comments in this discussion and it is well worth a listen and share, once edited. A superb conversation between Russ and HPAC members about iron and the ocean.
Dennis Garrity also spoke about the upcoming HPAC Online Conference - Preventing Two Degrees. Put the dates in your calendar if you can - October 15 and 16 for 2.5 hours from 8:30 am Eastern Daylight Time. Registration and information at https://www.preventing2degrees.org/

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.

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.

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.

Paul Gambill will be joining us to discuss his work on educating the public to understand that sunlight reflection methods will be needed in addition to emissions reductions and greenhouse gas removals to address the global heating emergency.
Paul co-founded Nori, the first carbon removal marketplace, and served as CEO from 2017–2023. An early pioneer in carbon removal, he helped establish it as a distinct industry category and led Nori to sell the world’s first soil carbon removal credits. After a decade building financial infrastructure for scaling carbon removal, Paul now writes at Inevitable & Obvious Substack about the hard lessons learned in carbon removal and why cooling interventions are essential for buying time while carbon removal reaches the scale climate science demands.
Paul will be discussing with us the new initiatives that he is developing to mobilize more support for comprehensive approaches to global heating.
Our CDR30
hashtag#VirtualPavilion is
here, bringing world-class climate expertise to your screen throughout COP30!
This Wednesday, November 12 (10:30 AM Belém time / 8.30 am EST / 1.30 pm GMT), we're convening the world's leading climate scientists, policymakers, and experts for a critical 2.5-hour virtual session at CDR30 - The Global Heating Emergency: What's the Plan?
With temperatures accelerating beyond projections and current strategies falling short, this session confronts the hard questions:
🌡️ Why is global heating accelerating faster than ever before?
⚠️ What happens to humanity and ecosystems if we don't act now?
🔄 How can carbon dioxide removal help us avoid catastrophic warming?
✅ What immediate, practical steps can build a new integrated climate
plan?
This session confronts the crisis with science, solutions, and a call to coordinated action.

Robert Chris will be presenting World Temperature Forecaster (WTF), his adaptation of the FaIR climate model.
After a brief introduction to FaIR and an explanation of what he’s done to make it more accessible to anyone with minimal Excel skills, he’ll illustrate how it answers some questions related to key issues we frequently discuss.
These will include zero vs net zero CO2emissions, why Watt for Watt, SRM and decarbonisation cool at much the same rate and the significance of their different radiative effectiveness, termination shock, impact of reducing short-lived climate forcers such as methane, and the impact of other non-CO2 emissions.
If you have a particular scenario you’d like him to address, send him an email by Wednesday evening to give him time to prepare it for presentation.
I’ll be in a plane from Bali to Seoul and since can’t connect please ask him for a scenario that saves coral reefs by causing ZERO future warming.
This year is expected to tie with 2023 as the second hottest year in history after 2024. The next El Niño, now just starting to simmer off Peru, will set new records.
Here in Bali we are growing incredibly beautiful corals (will post on Winter Solstice) but they are so stressed from years of warm water almost none are spawning!

I’m afraid you’re right!
World Temperature Forecaster (WTF) - adaptation of the FaIR climate model.
The temporary recording of video, audio, transcript and chat are here for upload of video to HPAC.
An AI summary generated from the transcript is attached. This will need to be reviewed for mistakes. Note the key finding that SRM is needed to return quickly below 1.5.
I thought this was one of the best ever HPAC meetings so encourage you to read the summary and watch the recording. Robert has created a simple and accessible way to compare main options for climate policy in an easy to use spreadsheet, simplifying the FAIR expert model to assess what combination of carbon and albedo actions can hold temperature within safe limits. This should be widely discussed to put climate conversations onto a better factual basis and generate more urgency for practical responses.
