I'm Alex Bloomberg and this is the show where we talk about what we need to do to address

climate change and how to make those things happen.

So we all know climate change is a big complicated problem.

If there's one thing people hunger for when faced with a big complicated problem, it's

a big, simple solution, a technofix.

And there are no shortage of candidates for the climate change technofix, the green silver

bullet.

I guess it would be just the green bullet.

But here on this show, we are technofix skeptics.

And that's because we've seen these solutions come and go for years, like next generation

nuclear that's been just around the corner, but not quite here for decades.

And we've come to peace with the fact that there will not be one perfect solution, but

many, many different solutions.

Which for you listeners is probably a good thing.

The podcast would get sort of boring if it was the same thing each week.

Welcome back to episode 593 about the giant sunshade.

But that doesn't mean that technological solutions aren't part of the mix.

Indeed, a big part of the transition underway right now in clean energy is due to pretty

miraculous technology advances, advances, for example, that made wind turbines and solar

panels much, much cheaper and much, much more efficient.

So this week, we are suspending our skepticism of technofixes, and in fact, we are going
