A. Climate change is warming the ocean,but its warming land faster and thatsreally bad news for air quality all overthe world, says a new University ofCalifornia, Riverside study. The study,published February 4 in Nature ClimateChange, shows that the contrast inwarming between the continents andsea, called the land-sea warmingcontrast, drives an increasedconcentration of aerosols in theatmosphere that cause airpollution. Aerosols affect the climatesystem, including disturbances to thewater cycle, as well as human health.They also cause smog and other kinds ofair pollution that can lead to healthproblems for people, animals, andplants.
B. To determine this, the researchersran simulations of climate change undertwo scenarios. The first assumed abusiness-as-usual warming model, inwhich warming proceeds at a constant,upward rate. The second model probeda scenario in which the land warmed lessthan expected. In the business-as-usualscenario, enhanced land warmingincreased continental aridity and,subsequently, the concentration ofaerosols that leads to more air pollution.
C. A robust response to an increase ingreenhouse gases is that the land isgoing to warm faster than the ocean.This enhanced land warming is alsoassociated with increased continental
aridity. The increase in aridity leads todecreased low cloud cover and less rain,which is the main way that aerosols areremoved from the atmosphere.
