I tend to think we can, but all the evidence is we certainly are not yet.

That's an assumption I'd be prepared to bet against. We haven't done ****, and won't do until far too late.

2020 ties for the warmest year on record. This is in spite of La Nina conditions in the second half of the year. The first 3 months of the year were a very weak El Nino, right on the edge of ENSO neutral. Not enough to explain the record temperatures and not enough to outweigh the La Nina conditions of the second half of the year.

Interesting piece here from Pro Publica - not a scientific analysis, but a climate scientist and the barriers they face in the public arena: https://www.propublica.org/article/t...ens-if-you-try

pretty good so far. Got the plan and a few people willing to volunteer their land for soil samples. A guy willing to donate lawyer skills. etc....

The big issue is finding a commercial soil sample lab for the right SOC sample and testing protocol.

The collapse of the coal industry has already begun.

Energy Australia to close Yallourn power station early and build 350 megawatt battery

Quote:
Energy Australia will close the Yallourn power station in Victoria's Latrobe Valley in mid-2028 four years ahead of schedule and build a giant power-generating battery instead.

The brown coal-fired plant has been operating for 47 years and produces about a fifth of the state's electricity.

Yallourn is Victoria's oldest power station and was scheduled to close in 2032.

It employs 450 permanent workers plus hundreds of contractors.

My opinion is that by the time a viable solar geoengineering scheme is ready to be implemented, it will no longer be needed.

I hope you're right, because trying something when you have no idea what the otucome might be is insane.

The length of time it would take to model and simulate and predict to a reasonable enough level of accuracy is why I reckon that by the time it's ready to implement we will have resolved the climate crisis by other means. But hey, research is research and if the National Academies want to throw money at this, they're perfectly entitled to.

This is not good news:

One of Earth’s giant carbon sinks may have been overestimated - study

Quote:
The storage potential of one of the Earth’s biggest carbon sinks – soils – may have been overestimated, research shows. This could mean ecosystems on land soaking up less of humanity’s emissions than expected, and more rapid global heating.

Soils and the plants that grow in them absorb about a third of the carbon emissions that drive the climate crisis, partly limiting the impact of fossil-fuel burning. Rising carbon dioxide levels in the atmosphere can increase plant growth and, until now, it was assumed carbon storage in soils would increase too.

But the study, based on over 100 experiments, found the opposite. When plant growth increases, soil carbon does not. The finding is significant because the amount of organic carbon stored in soils is about three times that in living plants and double that in the atmosphere. Soils can also store carbon for centuries, whereas plants and trees rot quickly after they die.

But to understand why you must dig deeper. For example the forest soils did not store any more organic carbon at all. Something I have repeatedly stressed over and over. That is the wrong biome. Forests store more biomass, they are not the terrestrial biome that sequesters stable carbon. The study also showed that in grasslands, elevated CO2 led to +9% plant growth, but soil carbon rose by 8%.

People have repeatedly been trying to say forests are the biological feedback to increased CO2, but the evidence shows it is grasslands not forests. Grasslands that at least in the US are estimated at ~80% degraded. There is huge potential in restoring grassland biomes.

Pixel42,
Just to add to the above. I wrote a much better answer on Quora why and how back in 2017, 3 1/2 years ago. Here is a link: How many trees do I need to plant to offset the carbon dioxide released by a person living 80 years in the west?
I think I will now upgrade that answer with the Nature Study. Thanks for the link! But don't worry. We got this!

To poke at a link that's a little relevant...

API Wants You, The Consumer, To Pay The Price For Its Pollution

Short summation? American Petroleum Institute has signaled a willingness to come to the negotiating table on a carbon tax... provided a number of sabotage conditions are met. For example, removing other environmental and public health safeguards, getting the government to give them even more money to clean up their natural gas messes and sell that gas, for them to receive credit when their product is used in other products... like plastics, that consumers know how much the any carbon tax is theoretically costing them, clearly marked at gas pumps because it's the consumers that truly need taxed instead of API as the petroleum is pumped out of the ground, and the like.

**** them.

They know they're on the ropes and they don't like it. Progress will be made despite them.
