“Cutting fossil fuel emissions is the only thing that changes the path” —Ingmar Rentzhog (Forbes 9 July)

[Douglas Grandt]

Sweden’s Ingmar Rentzhog (CEO & Founder of We Don’t Have Time) makes the case for cooling intervention but fails to provide comprehensive effective solutions in his LinkedIn post and Forbes “long read” (his words) ‘Why A Record-Hot Ocean Is Supercharging The El Niño Effect’.

His two simplistic conclusions of reducing future CO2 and CH4 emissions forsake his own admission: 

“The seasonal effects are only the visible edge. The deeper changes are bigger, slower and, on any human timescale, permanent. The ocean carries heat downward, so warmth added at the surface keeps sinking, and even if we stopped all emissions tomorrow the deep sea would go on warming for centuries.”

I believe Rentzhog has positioned himself as a go-to influencer—along with other notable esteemed influencers—who, I believe, might be swayed to have an open mind about cooling rather than continued cooking Mother Earth and her inhabitants.

I wrote the following  comment on LinkedIn, because Ingmar reads and responds to commenters unlike others of his ilk, and I expectantly—perhaps naively—await a constructive acknowledgment:

“So, accumulated excess heat stored beneath the surface pokes its head where we witness the silent killer … yet we are distracted by delusional bandaides in our attempts to simply reduce future additions to the trillions of tons of latent warming. It’s not too late to think critically and speak clearly what is needed to intervene with effective means of bringing down Mother Earth’s Fever, equivalent alcohol rubs and ice baths at appropriate scale. Just cool it. Let’s get cracking and formally endorse and legitimize the required research into plausible cooling measures.“

Let’s leverage and expand upon Ingmar Rentzhog’s oversight or ignorance and endorse the case he has built for urgent cooling. People listen to him, trust him, pay attention.

Hans,

Excellent comment, especially well placed on Ingmar’s photo and post about his invitation to meet King Charles!

For those unable to access LinkedIn, Hans commented yesterday:

#BuyMoreTime is so important Ingmar as we have been dragging our feet at least since the '92 Rio Earth Summit, where UNFCCC, the COP process and to STABILIZE emissions was agreed by 197 nations.

By 2019 emissions had DOUBLED and are still increasing. Climate Warming is not the result of annual emissions, but by cumulative emissions. Much of this accumulated in the oceans.

Furthermore our planet has dimmed: it reflects back less incoming solar radiation. This explains this DOUBLE WHAMMY of 

➡️ More heat coming in

➡️ More heat being trapped

Of course we must REDUCE & even REMOVE emissions. But due to INERTIA in both Physics & Politics these measures need 'Time to have Effect'. As we are heading towards HotHouseEarth conditions WE DO NOT HAVE TIME.

Hence indeed the need TO BUY MORE TIME.

As Sir David King, Chairman of the Climate Crisis Advisory Group warned: The NEXT FEW years will determine our future for NEXT FEW THOUSAND years" https://vimeo.com/527806796

Next to Reduce & Remove it is indispensable to add www.Rebrighten.org to Cool the Climate and buy time for measures that tackle the cause.

I successfully searched Google climate change Summit in Bucharest Keynote by Hans van der Loo: WHAT IS NEEDED TO RE-IMAGINE OUR FUTURE

Following is the Google summary. I’ve opened the cited references but can’t see a link to video. Do you have a video link or transcript to share?

Best,

Doug

Hans van der Loo, Chairman of the Advisory Board for the Institute for Integrated Economic Research (IIER), outlined that fundamental changes in lifestyle and economic restructuring [1, 2] are required to re-imagine our future. His keynote emphasized that our current models are inherently unsustainable, and we must rapidly adapt to protect vulnerable coastal environments. [1, 2, 3]

His keynote addressed several critical pillars needed to navigate the climate crisis and re-imagine our future: [1]

• Rethink Infrastructure & Urban Planning: Much of global wealth and human population is concentrated along coastlines. With the threat of melting ice caps, major metropolitan centers (like Venice, Amsterdam, and Hamburg) are highly vulnerable to catastrophic flooding. Future planning must heavily prioritize robust, forward-looking coastal and urban resilience. [1, 2]
• Eliminate Upstream Carbon Emissions: Environmental damage occurs long before a product reaches the consumer. Using the manufacturing of a combustion-powered vehicle as an example, he highlighted that massive quantities of CO₂ are emitted into the atmosphere simply to produce the car, long before it is ever driven. This necessitates a complete overhaul of global supply chains and manufacturing footprints. [1, 2]
• Shift to Sustainable Lifestyles: True progress demands stepping away from the "produce-consume-waste" cycle. Fundamental lifestyle changes at both the individual and systemic levels are a prerequisite to preventing the worst-case scenarios of global warming. [2]

These overarching solutions align with the broader goals of the summit, which tackles the complex intersections of energy, industry, nature, technology, and finance to secure a sustainable tomorrow. [1, 2]

Hi Doug,

 

I noticed this as well. I know Ingmar as we were both speakers at the Climate Change Summit in Bucharest. I was invited to deliver the keynote speech following the President’s opening. (annex)

 

So I did react to Ingmar’s post along the lines you mention.

 

Best Regards,

 

Hans
