Sep 1, 2011. He calculates that soot accounts for between 15 and 20 percent of global warming. His study, presented this week at the American Chemical Society meeting in Colorado, describes how black carbon – the main component in soot – heats up clouds when it mingles with the rain drops suspended within them.
Global warming, also referred to as climate change, is the observed century-scale rise in the average temperature of the Earth’s climate system and its related effects. Multiple lines of scientific evidence show that the climate system is warming. Many of the observed changes since the 1950s are unprecedented in the instrumental temperature.
The warming in the Arctic is two times larger than the global average. The warming takes place due to heat transport from lower latitudes, but also due to emissions within the Arctic itself. Emissions of black carbon are of special importance because it warms the Arctic both by absorption of solar radiation in the atmosphere.
