Even if Donald Trump defeats President Joe Biden and tries to take a wrecking ball to US climate and environmental policies, he ultimately would be powerless to derail the inevitable renewables revolution that is gaining momentum worldwide. His anti-climate agenda would be another wall that never gets built.
And the U.S. Inflation Reduction Act is surprisingly well-designed to deal with the fallout.

Given that this year’s United Nations Climate Change Conference was hosted by a petrostate and led by a fossil-fuel CEO, climate campaigners understandably had low expectations. Yet the summit did deliver some new commitments, and there is good reason to think that they are more than just empty words.
It is both technically possible and economically feasible to eliminate almost all the carbon dioxide from iron and steel production by mid-century, thus cleaning up an industry that accounts for 10% of global emissions. But progress will not happen without a concerted policy push.

When the Price Is Right
Heated academic debates between proponents and opponents of traditional economic growth under capitalism might make for good television, but they offer little in the way of solutions. Climate change demands that we achieve both growth and degrowth, depending on the activity and economic sector in question.
As long as coal plants are still operating, it is a good idea to require them capture their carbon dioxide emissions. But those designing policies to hasten such practices must tread carefully, lest they unwittingly extend the life of dirtier energy sources.
Hint: It's about minimizing risks and uncertainties.
by Charles Komanoff and Gernot Wagner
To think that technology will save us from climate change is to invite riskier behavior, or moral hazard. Whether a climate technology creates new problems has little to do with the solution, and everything to do with us.
Rather than impeding the clean-energy race, the recent collapse of the US start-up community's go-to bank offers valuable lessons for managing the public-private minuet that the net-zero transition requires. The doomsayers are missing the bigger picture.
The US Inflation Reduction Act is a landmark legislative package that should be welcomed around the world, despite its putatively protectionist features. Owing to the positive learning-by-doing spillovers that follow from green subsidies, Europe and the rest of the world ultimately will benefit, too.
Build, build, build.
Geoengineering research flights are a good federal investment
