El Nino Southern Oscillation

American Temperatures to be Cooler and Hotter in Coming Winter

The National Oceanic and Atmospheric Administration has released its yearly Winter Outlook which tells of a second winter in a row which will be affected by La Niña which will bring continued drier and warmer than average weather in the Southern Plains and colder and wetter conditions in the Pacific Northwest.

Significant Environmental Events for August 2011

August was a month of extremes across the whole of our planet, with tornadoes, droughts and La Niña conditions reemerging despite having only disappeared a few months earlier. For a picture of much of what happened across the planet this past August, browse the image below provided by the National Oceanic and Atmospheric Administration.

Clouds Do Not Cause Climate Change

Despite recent scientific speculation to the contrary, clouds do not cause climate change, says Texas A&M atmospheric sciences professor Andrew Dessler. Rather, they act almost singularly as a feedback mechanism.

East African Floods and Droughts Caused by El Nino

East Africa suffers regularly at the hands of faraway climatic events such as the warm El Niño or the cool La Niña phases of the El Niño-Southern Oscillation (ENSO). Now, scientists know that the waxing and waning of floods and droughts in the region at the hands of ENSO has been a regular feature dating back 20,000 years.

Tree Rings Sure Up El Nino Data

An international team of climate scientists from the University of Hawai‘i at Mānoa have found that tree ring data, specifically from the US Southwest, agree well with the 150-year instrumental sea surface temperature records in the tropical Pacific that we already have of El Niño events.

El Niños Growing Stronger

Scientists have detected a new type of El Niño that is forming in the warmer waters of the central-equatorial Pacific Ocean, causing the El Niños to become more common and stronger. Researchers found that the intensity of El Niños has nearly doubled in the central Pacific. The research, conducted by Tong Lee of NASA’s Jet

World's Marine Plankton in Peril – 40% Decline Since 1950

Phytoplankton–tiny, marine plants that formthe basis of our oceans’ food chain–absorb and sequester large amounts of CO2 from the atmosphere and generate half of the world’s oxygen supply. Given such an important ecosystem service as this, one would hope that our oceans’ algae numbers stay high…but, the results of a three year data analysis are anything but encouraging.
