Reducing aerosol pollution without cutting carbon dioxide could make the planet hotter

Humans must reduce carbon dioxide and aerosol pollution simultaneously to avoid weakening the ocean’s ability to keep the planet cool, new research shows. Aerosol pollution refers to particles in the air emitted by vehicles and factories that burn fossil fuels. This pollution contributes to asthma, bronchitis, and long-term irritation of the respiratory tract, which can...

A warming world increases air pollution

Climate change is warming the ocean, but it’s warming land faster and that’s really bad news for air quality all over the world, says a new University of California, Riverside study. The study, published February 4 in Nature Climate Change, shows that the contrast in warming between the continents and sea, called the land-sea warming...

Global Warming, El Niño Could Cause Wetter Winters, Drier Conditions in Other Months

"RIVERSIDE, Calif. (www.ucr.edu) — So here’s the good news: Despite fears to the contrary, California isn’t facing a year-round drought in our warming new world. However, UC Riverside Earth Sciences Professor Robert Allen’s research indicates that what precipitation the state does get will be pretty much limited to the winter months — think deluge-type rainfall...

California Projected to Get Wetter Through This Century

"Under business-as-usual greenhouse gas emissions, climate models predict California will get warmer during the rest of the century and most also predict the state will get drier." Read More

Clouds are Moving Higher, Subtropical Dry Zones Expanding

"A University of California, Riverside assistant professor and a team of researchers have found that the cloudy storm tracks on Earth are moving toward the poles and subtropical dry zones are expanding. Cloud tops are also moving higher in the atmosphere. The findings, based on satellite cloud records, confirm computer climate models that have predicted...
