This is todays edition ofThe Download,our weekday newsletter that provides a daily dose of whats going on in the world of technology. A brief guide to the greenhouse gases driving climate changeSulfur hexafluoride (SF6) is used in high-voltage equipment on the grid. Its also, somewhat inconveniently, a monster greenhouse gas.Greenhouse gases are those that trap heat in the atmosphere. SF6 and other fluorinated gases can be thousands of times more powerful at warming the planet than carbon dioxide, and yet, because they tend to escape in relatively small amounts, we hardly ever talk about them.Taken alone, their effects might be minor compared with those of carbon dioxide, but together, these gases add significantly to the challenge of addressing climate change.Casey Crownhart, our senior climate reporter, has drawn up a quick cheat sheet on the most important greenhouse gases you need to know about.

At the same time, leading economists disagree about the potential impact of AI.Some anticipate a future of perpetually accelerating productivity, while others project more modest gains. But most experts agree that technological advancement, however buoyant, is no guarantee that everyone benefits.Ensuring that AI helps create a more inclusive future remains one of the least invested-in areas of AI governance. But paying attention to the factors that will influence the interplay between AI and inequality can help us make the idea that AI will benefit everyone into more than just a pipe dream.

As if that wasnt bad enough, more storms are coming, and many areas are not prepared.But some government officials and state engineers are hoping there is an alternative: elevation. The $6.8 billion Southwest Coastal Louisiana Project is betting that raising residences by a few feet, coupled with extensive work to restore coastal boundary lands, will keep Louisianans in their communities.Ultimately, its something of a last-ditch effort to preserve this slice of coastline, even as some locals pick up and move inland and as formal plans for managed retreat become more popular in climate-vulnerable areas across the country and the rest of the world.
