No good deed goes unpunished—and that includes trying to slow climate change. By cutting greenhouse gas emissions, humanity will spew out fewer planet-cooling aerosols—small particles of pollution that act like tiny umbrellas to bounce some of the sun’s energy back into space. “Even more important than this direct reflection effect, they alter the properties of clouds,” says Øivind Hodnebrog, a climate researcher at the Center for International Climate Research in Oslo, Norway.
This is the overall “energy imbalance” of the Earth, with it trending upwards as the world warms. The researchers then fed global emissions data into four different state-of-the-art climate models and managed to reproduce those satellite measurements.
