For Checking Sea Level Rise, Reduce Four Pollutants, say Researchers

Aixue Hu of the National Center for Atmospheric Research (NCAR) has said, "To avoid potentially dangerous sea level rise, we could cut emissions of short-lived pollutants even if we cannot immediately cut carbon dioxide emissions".

A study that has been conducted by Scripps Institution for Oceanography, NCAR, and Climate Central, says curbing emissions of certain pollutants can prevent the sea level rise. The researchers have come up with a handful of pollutants that can reduce the sea level in this century.

The study highlights that reducing four pollutants in atmosphere can provisionally prevent the rate of sea level rise by approximately 25-50%. Climate change has been a concerning factor for the world. Protecting the coasts has become all the more important in populated areas.

The 2007 assessment by the Intergovernmental Panel on Climate Change has released figures that say if temperatures continue to warm, sea levels can rise between 18 and 59 centimeters. This is a humungous increase, which can immerse densely populated coastal communities.

Though carbon-dioxide content has been held responsible for rising pollution, nothing appears to happen in this regard. The researchers aim at emissions of four other heat-trapping pollutants: methane, tropospheric ozone, hydrofluorocarbons and black carbon.

Alaska Fisheries are at Risk of ocean acidification: NOAA Warning

According to a latest research led by NOAA, acidification of oceans is bringing changes in waters that are important to commercial fisheries in Alaska.

Many marine fisheries of Alaska are in those waters that are experiencing ocean acidification at present and the study shows that they will witness more of it in the near future.
