Arctic Ocean full up with carbon dioxide

Loss of sea ice is unlikely to enable Arctic waters to mop up more carbon dioxide from the air.

As climate scientists watched the Arctic’s sea-ice cover shrink year after year, they thought there might be a silver lining: an ice-free Arctic Ocean could soak up large amounts of CO2 from the atmosphere, slowing down the accumulation of greenhouse gases and climate change.

But research published in Science today … Read the rest

Dying trees could exacerbate climate change

forestForests could emit more carbon than they store if temperatures rise.

Forestry experts have again warned that climate change could transform forests from sinks to sources of carbon. The carbon storing capacity of global forests could be lost entirely if the earth heats up 2.5° Celsius above pre-industrial levels, according to a new report.

The analysis by the International Union of Forest Research Organizations (IUFRO) is a synthesis of existing … Read the rest
