If anything is ever done, clouding up the sky with sulpher dioxide looks cheapest, so that would be a big part of the plan. Maybe we can figure out how to turn volcanoes on and off.

 

And at the same time capture the energy for useful purposes . .

 

Um, slight problem with controlling volcanoes, including destroying the ozone layer

The main concern is that we don't know enough and the possibility that we could easily make the the situation worse. A main problem is we humans don't get along with others very well and can't trust others not to weaponize climate control.

In addition to the concerns that you and RWatson raised, there is also the problem that reducing solar irradiation without also limiting CO2 output will not reduce the acidification of the oceans. Though a study reported in a previous post suggested that the oceans may be more resilient to acidification than previously thought.

NASA Satellite Sees Overheated Tropical Forests Oozing with Carbon Dioxide | Space.com

NASA's latest carbon dioxide-mapping satellite has detected a dramatic spike in the amount of the greenhouse gas in the atmosphere, measuring the largest annual increase Earth has seen in at least 2,000 years. The cause? Overheating of three major tropical forest regions across the globe.

NASA's Orbiting Carbon Observatory (OCO-2), is one of several satellites that collect greenhouse gas emissions data, and researcher Junjie Liu of NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, used this probe's data to uncover how much — or in this case, how little — carbon dioxide (CO2) was absorbed out of the atmosphere by Earth's tropical forests.

 

This one seems a little far fetched. I would be pleased if in 282 years the catch was only down 20% from current levels. It would not surprise me that if we do manage to get to 2300, there turns out to be only 20% left, if even that, due to overfishing, pollution, warming and acidification.

 

There is still a lot of this stuff sitting around. All these powerplants sit by water- lakes, rivers and oceans, and all the jury rigged, degrading storage systems are only temporary, many sitting in the open. Any disruption and it all goes downstream. It seems like an easy target with a big payoff for very little input.

 

Climate change leaves birds hungry as chicks hatch too late to eat caterpillars | Independent

Warmer springs due to climate change are leaving chicks in UK woodlands hungry, according to new research.

As springs get warmer earlier, caterpillar numbers spike too soon meaning by the time many birds' eggs have hatched later in the season, there is not enough food to go around.

The biggest mismatch was among pied flycatchers – as migratory birds, they are not in the UK in winter and therefore are much less able to respond to earlier spring weather.

 

Climate change an 'existential security risk' to Australia, Senate inquiry says | The Guardian

Climate change is a “current and existential national security risk” to Australia, a Senate inquiry has told parliament, one that could inflame regional conflicts over food, water and land, and even imperil life on Earth.

The Senate committee inquiry into the implications of climate change for Australia’s national security recommended an increase in foreign aid to be dedicated to climate change mitigation and adaptation in the region, as well as a government white paper on climate security, Department of Defence emissions targets and a dedicated climate security post within the Department of Home Affairs.
