Indo-Gangetic Plain a Hot Spot for Black Carbon (image) NASA/Goddard Space Flight Center Share Print E-Mail Caption Tiny air pollution particles commonly called soot, but also known as black carbon, are in the air and on the move throughout our planet. The Indo-Gangetic plain, one of the most fertile and densely populated areas on Earth, has become a hotspot for emissions of black carbon (shown in purple and white). Winds push thick clouds of black carbon and dust, which absorb heat from sunlight, toward the base of the Himalayas where they accumulate, rise and drive a "heat pump" that affects the region's climate.
