In carbon sequestration, money grows on trees

Guyana’s tropical rainforests protected under the REDD program provide not just natural resources but an income stream to the country.

Two hours south of Georgetown, Guyana, a paved highway recedes, giving way to a rutted red road gushing through thick rainforest. In its muddiest spots, the road swallows trucks and spits them out at dangerous angles. Many hours later, it leads to an area of protected land called Iwokrama, a … Read the rest

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

Report maps perils of warming

Degree-by-degree breakdown of climate effects published.

As the US Senate gears up to debate the latest incarnation of proposed climate legislation next week, a blue-ribbon panel has released what it hopes will be a definitive guide to the consequences of climate change for lawmakers and the public. In offering a degree-by-degree breakdown of the potential impacts of temperature change, the report aims to highlight the effects of stabilizing greenhouse … 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
