EU monitor says global temperatures were 1.75C above preindustrial levels, extending run of unprecedented highs

Climate scientists had expected this exceptional spell to subside after a warming El Niño event peaked in January 2024 and conditions shifted to an opposing, cooling La Niña phase. But the heat has lingered at record or near-record levels, prompting debate about what other factors could be driving it to the top end of expectations.

    One theory is that a global shift to cleaner shipping fuels in 2020 accelerated warming by reducing sulphur emissions that make clouds more mirror-like and reflective of sunlight.

    Paradoxically, we might be accelerating warming by burning less sulphur emitting fuels. Clean the air, heat up faster. It’s still a matter of debate, however, now much the reduction in sulphur emissions is causing the current accelerated warming. It’s entirely possible there are other factors at play, as well. That’s not going to stop people from advocating for geoengineering, though. Pump more sulphur dioxide into the atmosphere, cool the planet. I don’t know, I suppose.
