Black carbon aerosols — particles of carbon that rise into the atmosphere when biomass, agricultural waste, and fossil fuels are burned in an incomplete way — are important for understanding climate change, as they absorb sunlight, leading to higher atmospheric temperatures, and can also coat Arctic snow with a darker layer, reducing its reflectivity and leading to increased melting.

In a true black hole, the separation would be more pronounced; one of the particles would be lost for good to the black hole.

For those who aren't familiar with how it works, E Ink relies on tiny capsules containing both a clear liquid and black and white ink particles, which are electrically charged.

While this is perfect for creating resilient monochrome and even grayscale images, where teeny - tiny black and white particles arrange in different distances to the surface of the display to form an image, it poses a problem when trying to show things in color.

These differently - colored particles carry the same charge as the black ink, but move to the surface of the display under a different voltage, proving perfect for applications such as shelf labels and different billboards.

It's a problem for the climate because the black soot particles are just the right color to absorb heat from the sun, either in the upper atmosphere or when it settles back down to earth on Arctic snow and ice (when soot - free, the polar ice caps reflect a tremendous amount of light and heat back into Space, helping keep the planet cool).

It's that second part which really as implications for reducing warming from soot.Effects of Black Carbon Pollution Stop Quickly Once Source is Removed The good news about black carbon and global warming is this: Unlike greenhouse gases which can remain in the atmosphere for decades or even centuries, black carbon particles come out of the atmosphere very quickly once the source of pollution is remBlack Carbon Pollution Stop Quickly Once Source is Removed The good news about black carbon and global warming is this: Unlike greenhouse gases which can remain in the atmosphere for decades or even centuries, black carbon particles come out of the atmosphere very quickly once the source of pollution is remblack carbon and global warming is this: Unlike greenhouse gases which can remain in the atmosphere for decades or even centuries, black carbon particles come out of the atmosphere very quickly once the source of pollution is remblack carbon particles come out of the atmosphere very quickly once the source of pollution is removed.
