SRM not only can eliminate the temperature overshoot, but it also reduces the amount of CO2 that needs to be subsequently removed:
Solar-Geoengineering Can Reduce Overshoot & Emissions, with Peter Irvine

If we fail to reduce emissions, then we are choosing to fail. If we choose to fail, we will.
If we choose to succeed, then emissions reduction, CDR, and SRM will be part of the plan.
Yes, black carbon heats but impact is smaller than sulfur cooling (which creates/brightens clouds). Cleaner shipping fuels and sulfur scrubbers also decrease black carbon and acid rain.
Bottom line is that SRM is the *only* tool we have that can decrease temperatures in short to medium term.
While we are increasing CO2 emissions, we are reducing aerosol emissions by (1) using sulfur scrubbers on power plants & (2) requiring ships to use low-sulfur fuel.

But without SRM we are guaranteed to have higher temps than if we do SRM because cooling reduces feedback emissions (just like warming causes feedback emissions).

Also, it's too late for emissions reduction to work on its own (keep us below 2ºC or even 3ºC!).
Right now, one of the only ways to make money with CCS is to sell the captured CO2 to FF companies. That is a policy failure, not a technology failure.
With proper policies, CCS can greatly reduce industrial emissions while we wait for green cement, steel, etc. solutions to scale.
CCS does work & captured CO2 does not need to be used to get more fossil fuels. He is confusing technology with policy. Right now it is free to pollute the atmosphere with CO2, so don't expect CCS to scale until policy requires it or governments agree to pay for it.

I think you misunderstand what I was saying. I love renewables & think they will play a major role in getting us off of FF. But the focus on subsidizing RE rather than phasing out FF leads to more RE & not less FF. If we phase out FF, it will make RE grow tremendously!

The percentage of renewable energy (RE) is irrelevant to climate change. Only the absolute amount of fossil fuel (FF) emissions matter. So far, RE has only added to energy supply; It has not replaced FF energy yet.
We need to focus on phasing out FF, rather than growing renewables!

Why are you annoyed? For many tipping points, the negative impacts are sea level rise, change in precipitation patterns and growing regions, local temperature changes, etc. Global temperature triggers them but they do not necessarily have a big impact on global temperature in the near term.

Tipping points are a clear and present danger which are based on real science (as you can look up).

It underplays Hansen's work, saying it only relies on paleoclimate (ice age) info. That's not true. Hansen (& @leonsimons.com) also use recent temp readings during IMO2020 changes, and also used decrease in Earth's measured albedo in past 25 years.
