| As interest in Earth's changing climate heats up, a tiny dark particle is stepping into the limelight: black carbon. Commonly known as soot, black carbon enters the air when fossil fuels and biofuels, such as coal, wood, and diesel are burned. | ||||||||||

| Black carbon is found worldwide, but its presence and impact are particularly strong in Asia. Black carbon, a short-lived particle, is in perpetual motion across the globe. The Tibetan Plateau's high levels of black carbon likely impact the region's temperature, clouds and monsoon season. Black carbon is a product of incomplete combustion. It comes from industrial pollution, traffic, fires, the burning of coal in homes, and bio-mass fuels. Unlike carbon dioxide, which traps heat in the atmosphere, soot emissions may contribute to global warming and climate change by absorbing sunlight. This process heats the air and destabilizes the atmosphere. (Source: NASA) |
