So the next idea was El Nino, which is part of this natural climate cycle. And during El Nino years, the planet is generally warmer. But when it first got unexpectedly hot, El Nino hadn't even started yet. Gavin Schmidt is a climate scientist at NASA's Goddard Institute of Space Studies.

It turns out that El Nino probably had some effect on 2024's numbers, but overall, scientists were still scratching their heads.

Yeah, they went to one other place, Scott. The next thing they looked at were these weird kinds of clouds.

That's Andrew Gettleman. He's a climate scientist at the Pacific Northwest National Laboratory. Ships burn fossil fuels, and the pollution from that actually creates these cloud trails behind them that cool Earth. And in 2020, that ship fuel actually got cleaner, and that meant smaller ship track clouds and increased in turn, a hotter planet.

And that could actually make up about half of the mystery heat. And scientists think decreases in other clouds that were also formerly caused by pollution might make up another chunk.

Yeah, it's not ideal. But scientists like Schmidt say that that just means cutting fossil fuel emissions is even more important to get at that main driver of climate change.

Yeah, glad to be here. Thanks.

Yeah, even though, as we'll get into later, Ozempic is a diabetes drug.
