The 10 indicators of climate change include measurements of sea level rise taken from ships, the temperature of the upper atmosphere taken from weather balloons and field surveys of melting glaciers.
Beyond warming the atmosphere, black carbon can also speed the melting of glaciers by literally turning them black - soot on snow makes the ice heat up faster.
除了给大气加热，炭黑还能覆盖冰川表面，便其表面颜色变黑，从而加速冰川融化。

And I care about what happens with the Big 3 because they are more responsible than almost anyone for the destruction of our fragile atmosphere and the daily melting of our polar ice caps.
