We are adding 215,000 people to the human population every day and all the energy they will emit.

If we wanted to freeze permafrost to stop the output pf CO2 and methane of its melting how much CO2 do we have to remove from the present 420 ppm to get it to over ride ocean heat warming and accomplish refreezing. Can it be done? The existential question. Yes or No? To be or not to Be.

Crop Failure at 45 C near at hand and spreading. More heating undesirable. We are losing 25,000 peple per day today from starvation and drought aggravated by wars and dislocation and are seeing temperatures exceeding 45 C in places we have never experienced in human history.

How are we doing so far with those meetings? Making any headway or are they just gab sessions?

Looks like exponential increase with no change in shape and no effect of any policy decision since Meetings first commence. D-

Even if we cease/remove CO2 emissions there is committed warming tied up in the oceans. So we will, globally, continue to warm. Ruth But I don't know if it's possible to locally change the trajectory. Ruth Of course the Arctic is hard because it is warming so much faster than anywhere else, but there are things that can be done. Ruth Collaborators of mine have a paper in review right now looking at the transport of aerosols, especially black carbon, to the arctic. It has a lot of very important policy recommendations. Ruth Ruth Digby Changes like that could help. You sent Thanks Ruth Probably some interesting reading here: Ruth https://acp.copernicus.org/articles/special_issue1143.html ACP – Special issue – Arctic climate, air quality, and health impacts from short-lived climate forcers (SLCFs): contributions from the AMAP Expert Group (ACP/BG inter-journal SI) Ruth That's the group Ruth Ruth Digby But the paper I'm referring to is not available yet. From Ruth Digby, Climate Model PHd ADAPTATION IS THE NEXT STAGE OF OUR REPSONSE. THE SCIENCE PAINTS A GRIM PICTURE OF OUR FUTURE. Adaptation will require an enormous change in our economies, our relationship to manufacture and construction and materials extraction and use, and in particular to our expectations of what and how much we can expect from nature, and changes to our habits in many aspects. Most imporantly we will have to relearn to live with nature within the limits that it imposes in a shrinking survival space. The permafrost, methane and the stored heat in the oceans will be raising the temperature primarily in the northern regions and this will lead to change in human populations. The survival of sufficient agriculture to ensure our long term continuence is not assured under present growth patterns and attendant climate changes we are observing. Adaptation may offset some of the coming challenges but the 45 C limit on photosynthesis is a bug in the works going forward. The rapid urgent transition from fossil fuels is of course the best opportunity to minimize impacts and downsizing population thorugh family planning must also be a part of the solution. Protection of the big ecosystems must be paramount to ensure the life support system of Planet Earth. Capitalism itself must impose limits that comply with survival needs and shelving of costly deleterious wants and the very concept of growth. The Wealthy developed countries of the world that caused enormous harm by greenhouse gas emissions to the poorest must also help their victim countries to adapt through financial and other support proportional to the costs they added to their lives. I EXPECT THE EXTENT AND MAGNITUDE OF THE OCEAN HEAT FORCING TO BE DEPENDENT TO A CONSIDERABLE EXTENT ON THE DEGREE OF OUR ELIMINATION OF FOSSIL FUELS IN OUR ENERGY MIX BUT ONCE THE METHANE CLATHRATES KICK IN WE MIGHT LOSE ANY SIGNIFICANT IMPACT ON OUTCOMES. PAST TIME TO GET WITH THE PROGRAM
