Global warming appears to have shifted into a faster gear. After removing the effects of El Niño, volcanic eruptions, and solar cycles, researchers found that the planet has warmed at roughly 0.35°C per decade over the past ten years, compared with just under 0.2°C per decade from 1970 to 2015. The acceleration, which becomes visible around 2013 to 2015, appeared across five major global temperature datasets with more than 98% statistical certainty.
Yeah, there’s localized effects. Like where I live, particulate matter and ozone skyrocketed after they installed a massive gas-powered datacenter in the neighboring town. But globally, it takes forever for these effects to pile up and cause a dent. Which is why they are measured in average increase per decade.
Main source of those is combustion engines btw
There hasn’t been a doubling of car traffic in the same time period.
