You forget the phosphate supply problem. Long before 2500, we will have run out of mineable supplies and current agricultural will be impossible. Aquaculture and synthetic food production will dominate. With modest vegetable production from recovered phosphates.

Another suggestion, could we use this to map methane clathrates and their stability in the high arctic. Understanding this matters to monitor climate change.

I also think it could be used to map old tips which have poor or non existent records. This could be very important.,

I wonder if you could apply this to finding leaks from water and sewage pipes. I suspect the latter often goes unnoticed until big problems.

The assumption of the amount of energy storage required is incorrect. Ultimately to be secure, countries need approximately 91 days of total energy storage. As we shift to electricity that how much we ultimately will need. Orders of magnitude larger

It’s worse than you mention. I ran a team that created new carbon capture and utilisation. We created great technologies that worked and were profitable from the byproducts they made. The powerful kept changing the rules, told us it would continue as they did not want to actually see this happen.

on the addition of an extra runway. The build will release 1.5 million tons of CO2 but the extra 100,000 flights will add 75 to 100 million tons per year. The liability these emissions will create more that wiped out the predicted 1 billion pound extra economic activity the runway will add.

Worth noting that the modelling does not include green glacier melt. The situation is worse therefore than the models.

There is another explanation. This may be evidence that the AMOC is slowing and delivering less warm water to the Arctic. The warm water blob in mid North Atlantic supports this. This would mean the AMOC collapse is progressing. Very very bad.

I was told this by an ex senior manager who worked for air product who tried and failed to get the company to do this. He outlined to me in consideration detail how those would have worked. The link below is one of many that discuss recycling tyres this way. pmc.ncbi.nlm.nih.gov/articles/PMC...
A Multifaceted Approach for Cryogenic Waste Tire Recycling
One of the important aspects for degradation of the life quality is the ever increasing volume and range of industrial wastes. Polymer wastes, such as automotive tire rubber, are a source of long-term...

Easy way to deal with old tyres: take waste cooling from air fractionation (we do lots of this). Freeze tyre. Hit with hammer, shatters like glass. Easy recovery of steel. Rubber particles have lots of uses. Works for old mattresses too.

This is impressive research of a new dynamic in warming glaciers. Trying to wrap my head around the implications…

Not necessarily. If the amoc collapse or worse case climate change happens, it will be very hard to know where is a safe harbour. To make matters worse, the safe place will likely shift in short periods of time to a different place if the climate swings as it could.

Reality does not care if you believe in it or not . It will continue regardless. Ignoring climate change and what’s coming is like ignoring a cancer diagnosis that could be curable if you act quickly.

The above sequence of steps means that a heat circulation loop from deeper waters to surface waters would be formed. This will have implications potentially for the AMOC and for the formation of the cold briny water formation in the Davis Strait.

The lower salt water then mixes with the more salty warmer waters that are at depth. The heat of mixing creates heat. This then lowers the density of the water and warm salty water then rises to the surface.

potentially, you could end up creating warmer salty waters at lower depths.
The warmed water from step 2 would become more dense and sink as it moves towards 4 C.

Water is less dense at near zero but at 4 C (if memory serves me right) water is more dense and sinks. When ice forms in salt water, you get brine rivulets that will fall to deeper waters. In situations where ocean current arrangements allow it,

The potential mechanism of this may be:
Melting ice produces cold lower salt water that initially is less dense.
Lower salt water mixes this salter water. The heat of mixing raises the sea water temperature. (I have not done the heat calculation for this)
