In the mid-2000s, the energy imbalance was about 0.6 watts per square metre (W/m2) on average. In recent years, the average was about 1.3 W/m2. **This means the rate at which energy is accumulating near the planet’s surface has doubled. **
FAaFO , we’re in the find out phase.
Yes. Exactly. The aerosols have a cooling effect that is fast-acting but short-lasting. Carbon dioxide has a warming effect that is slow-acting but long-lasting. In the long term, the warming effect prevails, but on an annual basis, the cooling effect dominates. We no longer have centuries to address climate change, so considering what the effect of any mitigation strategy will be in the short term is crucial.
