One of the most immediate and obvious consequences of rising global temperatures, which will become even more apparent in the coming years, is the increase in the number and intensity of wildfires. In most cases, fires are caused by humans, but due to a warmer and drier climate, they are spreading faster and causing even more devastating damage. But there is another novelty, just discovered by a group of researchers and published in Nature Geoscience: it is the phenomenon of dark brown carbon, a class of particles released by wildfires that was thought to help combat global warming, but which we have only now discovered. It had the opposite effect. (Focus)
