Interactive Sea Level Anomalies Map Launched

The Permanent Service for Mean Sea Level has been collecting data from all over the world and collating it at the National Oceanography Centre (NOC) in Liverpool, England, since 1933. They have now released their latest interactive world map allowing users to explore the changes in Earth’s sea level. The Mean Sea Level Anomalies map

Weak La Niña to Strengthen Slightly Over Coming Year

La Niña conditions have re-emerged in the tropical Pacific Ocean since August 2011 but are weaker than the previous episode. However, this La Niña episode is expected to strengthen slightly over the coming year, and is likely to persist through to the end of this year and into early 2012, possibly reverting to a neutral

Extreme Ice Sheet Melting Does Not Need Extreme Heat

New research has provided evidence to suggest that massive melting of ice sheets like the Greenland ice sheet does not need corresponding record temperature highs, rather, just persistent warm weather over several years. Such results suggest that glaciers and ice sheets could undergo a self-amplifying cycle of melting and warming simply if there is persistently

Ocean Currents Impacted Ancient Global Cooling

New research that has been published in the journal Science has showed that the Antarctic Circumpolar Current (ACC) may have played a key role in shifting the global climate some 38 million years ago, and provides the first clue that the early ACC may have played a critical part in the formation of the current structure of our oceans.

Understanding Melting Glaciers and the Oceans

Focusing their attention on the collapse of the Barents ice sheet which took place some 140,000 years ago, scientists from Bangor University and the University of Sheffield have used a computer climate model to understand how different states of freshwater entering the oceans affect the circulation of the oceans.

Strength of Japan Earthquake Increased to 9

Following in the steps of Japan’s Meteorological Agency, the U.S. Geological Survey have agreed in upgrading the shattering earthquake that hit Japan on March 11 to a magnitude 9. This means that the earthquake was approximately 1.5 times stronger than originally thought.

Plate Tectonics Apply to Continents Too

Scientific debate often rings immediately boring in many minds, with assumptions suggesting that the topic at hand is simply an academic one, and nothing important or impacting. Such is not the case for the debate over whether plate tectonics apply on the continental scale as well as on the fault scale, as more knowledge in

NASA Giving Climate Science Funding a 62% Boost

NASA planning a 62% boost in climate science funding by 2015, to make up for cuts made during the George W. Bush administration. [social_buttons] NASA has announced a dramatic climate science budget increase this month. Although, it is really just a correction for dramatic budget cuts made during the George W. Bush era.
