evidence: On a larger 10-year time frame, which scientists prefer to single years, the world has warmed about 1.19 degrees Celsius (2.14 degrees Fahrenheit) since pre-industrial times, the report in the journal Earth System Science Data found. [...] Scientists had theorized a few explanations for the massive jump in September, which Hausfather called "gobsmacking." Wednesday's report didn't find enough warming from other potential causes. The report said the reduction of sulfur pollution from shipping—which had been providing some cooling to the atmosphere—was overwhelmed last year by carbon particles put in the air from Canadian wildfires.
