Why would sea-level rise for global warming and polar ice-melt?

by A. Alam Khan, February17, 2018 in GeoScienceFrontiers


Highlights

• Global warming and polar ice-melt not contribute to sea level rise.

• Melting of huge volume of floating sea-ice around polar region cool ocean-water preventing thermal expansion.

• Polar ice melting re-occupy same volume of the displaced water causing no sea level rise.

• Gravitational attraction of the earth plays a dominant role against sea level rise.

• Melting of land ice in the polar region allow crust to rebound elastically for isostatic balancing through uplift should cause sea level to drop relatively.

Conditions for formation of Super El Ninos determined

by Anthony Watts, July 12, 2018 in WUWT


A University of Aizu team has identified two distinct Indo-Pacific processes shaping the unique features and extraordinary ferocity of super El Ninos. A systematic analysis of these processes and their interactions will improve forecasts of the elusive super El Ninos, the researchers claim.

Extremely warm  are a notable feature of the super El Ninos that occurred in 1972, 1982, and 1997. The fact that Pacific Ocean processes responsible for generating regular El Ninos could not explain this key signature of super El Ninos came as a big shock,” says Dachao Jin, co-author of the study.
