So That's All Right Then?

Maybe not quite! But I am sure the professional global warming sceptics will grab at it with both hands...

Ice loss offsets global warming: study

Their estimate, based on images of green algal blooms, is that the phytoplankton absorbs 3.5 million tonnes of carbon, equivalent to 12.8 million tonnes of carbon dioxide (CO2), the principal greenhouse gas.

To put it in perspective, this is equivalent to the CO2-storing capacity of between 6,000 and 17,000 hectares (15,000 and 42,500 acres) of tropical rainforest, according to the paper.

The tally is minute compared to the quantities of greenhouse gases from fossil fuels and deforestation, which amounted to 8.7 billion tonnes of carbon in 2007.
