Climate scientists know that emissions cannot be reduced to prevent more than 2 degree global change so will geoengineering get serious attention

In 2008 some climate scientiss said that the world had 100 months to enact drastic anti-global warming policies to avoid the environment warming by two degrees celsius compared to pre-industrial times. The 100 months have passed and only modest policies have been enacted and it seems likely that some of the policies will be reverse with more use of fossil fuels.
Global temperatures have already risen by 1 degree celsius compared to 1880.
What scale of change are we looking at to stay below 2C? Being optimistic about what might be achieved in terms of saving forests from being cut down and cleaning up industry, especially the production of steel and cement, Anderson estimates globally the world can afford to emit around 650 billion tonnes of carbon dioxide in total from energy systems. Currently, the world pumps out about 36 billion tonnes every year alone. Starting from today, and assuming that poorer and industrialising nations see a peak in the emissions from energy use by 2025 and go zero carbon by 2050, Anderson calculates that this leaves a rich country such as the UK with the challenge of cutting its emissions by around 13% per year.
Emissions have been going up fairly constantly. There has not even been a flattening of emissions. It is likely that the 650 billion ton budget will be used in 15-20 years.
The climate scientists were merely asking for about $100 trillion to be spent on climate mitigation between now and 2100. It is amazing that they are shocked and disappointed that the world has not enacted that program.
Effective geoengineering could be performed at about 100-1000 times lower cost. This would be
