The reason you see the hesitation is because with current technology 'stopping climate change' will require massively disruptive measures, likely leading to rather extreme loss of life. Inventing something new seems a whole lot easier, and fits with the general human tendency to 'do more' to work ourselves out of a problem.
Every part of the worlds economy is currently dependent on fossil fuels. Global trade (aka China and the US's economy, and most others too), International and most Domestic Travel, National Energy Grids (including heating in cold countries and literally keeping the lights on for large swaths of the year), and every major Army, Navy, and Air Forces basic operations.
Some countries or regions in countries have made progress towards zero carbon on SOME of those fronts. NONE of them are not reliant on fossil fuels at least some part of the year for something critical. As in, people will die, sometimes a lot of people (10-100k+).
And that isn't counting things like nitrogen fertilizer production, which have knock on effects everywhere.
To 'stop' global warming, we'd need to stop adding CO2 to the atmosphere essentially now, and start pulling CO2 out, correct?
So:
1) That currently is impossible for anyone to do without people dying.
2) It's likely to be a decade or more before the earliest adopters and wealthiest countries could get there (not counting Military, which is likely even longer - 50+ unless there is a major war first).
3) The BRICs on the list are relatively poor, and don't have as much ability to capitalize such a change. Most of the other countries struggle to keep their lights on as-is, with cheap oil. They aren't going to be able to capitalize converting their entire grid to solar, they can't even capitalize their current grid!
So, we essentially have two choices if we want to actually stop it now:
1) Figure out a way to fix our current situation, knowing that the majority of the worlds population isn't going to change what they are doing in time.
2) Go to war, and destroy anyone who won't stop doing what they're doing that causes CO2 release (and other GHG).
Which #2 would currently require even MORE expenditure of CO2 with current technology, assuming it's even winnable. China is a nuclear power after all, and the #1 global CO2 emitter (and one of the largest beneficiaries of global trade, which largely don't count in that number).
That's also of course putting aside ethical concerns about 'killing them to save them', and pre-emptive war to stop a problem that so far people are only feeling the barest twinge of issues from.
My gut feeling for what is going to happen is a lot of hand wringing, a lot of natural disasters that steadily build up pressure to actually do something, and a gradual transition and mitigation at great expense over a century+. This will likely completely screw the poor countries, and moderately screw the wealthy ones.
I think the issue boils down to known and controllable disruption (i.e. you are an active participant) or unknown and uncontrollable disruption in which you just receive whatever happens as it happens. The problem is nobody will vote for controllable disruption and many will actually vote to accelerate and grow the problem so we're stuck rolling the dice. Examples of this are things like municipalities, or counties, or states (in the US) banning construction of new wind turbines in their county (this happened in Ohio recently) and then funneling government money into subsidizing fracking or oil and gas production.
We're going to get these wars anyway because countries with a military will just start conflicts over resources and where nations break down many will just resort to anarchy and suffering there. We're already seeing this with Russia invading Ukraine where there are fascist goals but also geographic goals with control the fertile Donbas region and then also the subsequent usage of gas as a weapon against Europe. This is just the beginning.
It's hard to see how technology will solve this problem because it's a political and social problem and not a technology problem. No amount of carbon capture technology can build solar power in India while they're at war with China over water from the Himalayas ya know? No amount of technology can stop (at this time) Republican governments from banning EV installations or using government money to incentivize oil and gas industry development for donors.
Wars over resources are far different than a ‘war on global warming’, which is what I was referring to.
The technology would have to be similarly transformative as nitrogen fertilizer was - which is what avoided the whole Malthusian population trap in the first place.
We don’t know what we don’t know there, frankly, so hard to say if it exists or not.
Co2 capture and most GHG emissions though have a serious thermodynamic challenge which says ‘not easily’. Once the clock spring is unwound, it’s really hard to wind it back again.
And for those of you who debate my conclusion up there about the impact, consider this breakdown [https://www.worldometers.info/co2-emissions/co2-emissions-by...] and;
