Sea Level Rise unstoppable: emissions reduction needed to enable climate adaptation

Well this is a nice pickle! It seems that sea level rise won't stop even if we aggressively mitigate global warming and keep global average atmospheric temperatures beneath 2 degrees celsius. The reason, it seems, is there is enormous inertia in the world's oceans and we are now warming the deeper ocean which will continue for hundreds of years.
Simple physics really. You heat a liquid and it

Forest soil carbon release a vicious Global Warming feedback loop say researchers

Global warming is likely to accelerate release of forest soil carbon say researchers. This is another climate feedback loop. Rising temperatures are likely to accelerate forest soil carbon decomposition leading to more CO2 released into the atmosphere, compounding global warming. Rather than these forests acting as a carbon sink, warmer temperatures may make them a major source of greenhouse gas

Sea ice volume: Multi-year arctic sea ice reducing dramatically


A new study has noted a substantial decadal decline in the Arctic Multiyear ice cover. While ice extent has been shrinking, much of this is seasonal ice that reforms each winter and can grow with variable weather factors such as changes in temperature, wind, weather and ocean currents. A reduction in the thicker multiyear ice indicates a much greater impact and collapse of sea ice is evident.

Cyclone Intensity in North Indian Ocean linked to increasing air pollution

A recent study linked increasing air pollution over the Indian sub-continent to an increase in the intensity of Tropical cyclones in the Arabian Sea. The air pollution over the Indian sub-continent changes wind circulation patterns reducing wind shear in the Northern Indian Ocean providing more potential for intense cyclones to form. This is combined with warm sea surface temperatures in the
