I would suggest starting by policing the left from rolling their grab-bag of left-wing political ideas into the 'Green New Deal". The opposition from the right largely comes from the belief that the left is attempting to use Climate Change to pass left-wing policies that either don’t help with climate change, or actually make the problem worse.
For example, we now hear the term ‘climate justice’, which apparently wraps racial issues into the climate change debate. Biden wants hundreds of billions for new trains, which will make climate change worse, at least for the next 20 years and will soak up resources that could have been used in actually effective ways. The ‘Green New Deal’ has union-only and ‘buy American’ provisions which will make mitigation slower and more expensive.
And most of all, the continued refusal to consider nuclear power seriously calls the whole thing into question, as nuclear power is the only energy source we have today that could make a dent in CO2 emissions in a reasonable period of time. If it isn’t at the front and center of any climate change plan, the plan isn’t serious.
I actually read one article against nuclear power that said one of its major problems is that it rewards the ssme old big industrial companies, whereas wind and solar would create ‘good green jobs’ for everyone. If you are serious about global warming all you should care about is what reduces atmospheric CO2 fastest, rather than focusing on whether the right kind of people get the money.
That kind of talk is absolute poison when trying to get skeptics to join the cause.
Then there’s Biden’s inconsistencies which make one think that he doesn’t really believe in Climate Change either, other than as a useful tool for domestic politics. Because right after he shut down a whole bunch of U.S. exploration and pipelines, he bent over backwards to override sanctions and allow Russia to build its pipeline to Europe. Then he went and tried to browbeat OPEC into opening up more production to drive down the price of oil, stimulatng demand for it and makng alternative energy harder to fund.
Politicians and celebrity activists could also make themselves more believable by walking the walk they expect everyone else to take. John Kerry wrings his hands over Global Warming and tells everyone they have to sacrifice, then jets off in his Gulfstream. A common saying amongst denialists is, “I’ll believe climate change is real when the people telling me it’s real act like it’s real.” Don’t go out and claim that sea level rise will devastate us in 20 years, then buy an ocean-front mansion.
Let’s see a real plan for controlling China’s emissions. Because if China is allowed to keep building out cheap coal power, they will simply capture the west’s heavy industry and nothing will change except for a massive wealth transfer. That’s already happening, and China is by far the largest emitter of CO2.
So if we broke our backs and our economy to transition to expensive, unreliable and intermittent power only to watch China generate 75-80% of the world’s CO2 and it’s higher than it ever was, what’s the point?
One reason we need nuclear is because we could actually transition away from carbon while improving the economy and retaining or improving our comparative advantage in energy - a promise the greens always make but is complete horseshit when you are transitioning from dense energy sources to diffuse energy. Cheap nuclear power would remove the incentive for heavy industry to simply move to China.
Finally, At a time of scarce resources Biden is about to spend America’s wad on a giant 3.5 trillion dollar ‘stimulus’ that has nothing to do with climate. The Green New Deal comes after that, but there will be no political capital (or any kind of capital) left for that. If he really cared about global warming, he woild have made sure that those bills passed first while Democrats have control of all three branches.
So before tackling the deniers, it might help to clean house on the left and get rid of the bullshit that makes the deniers suspect it’s all a stalking horse for ‘fundamentally remaking’ society and the economy. Because as long as they keep getting evidence that this is at least partially the case, you’ll never get them on board. Anyone who says stupid things like ‘Global Warming can’t be fixed while we still have Capitalism"’ should be run out of the debate on a rail. They are doing more harm to progress than a hundred deniers, because they’ll create a thousand with such crazy talk.
