Climate Change Pollution Rising—Thanks to Overwhelmed Oceans and Plants: Scientific American

Climate Change Pollution Rising—Thanks to Overwhelmed Oceans and Plants: Scientific American

Oceans play a critical role in absorbing carbon dioxide from the atmosphere. 70-80% of the carbon dioxide will end up in the oceans. Oceans are far more important than terrestrial systems such as forests, which may not even be a net sink for carbon in temperate regions. So evidence that the rate of absorption is slowing down is a real cause for concern. The rate of decline is much faster than anyone might have anticipated, so this study is going to be subject to very close scrutiny. The backdrop is that emissions have risen from 8.4 to 9.9 billion metric tonnes between 2000 and 2006.

The challenge for the UK is that as gas prices and oil prices have risen, there is more incentive to use coal as a fuel source. So emissions have risen because coal is cheaper, even when companies have bought emissions rights. Its one of the paradoxes of climate change that expensive oil could increase overall emissions as suppliers switch to coal.

globeandmail.com: Greenhouse gases already beyond 'worst-case,' scientist says

Respected Australian climate change expert, Tim Flannery, has announced that the IPCC will soon announce that economic growth has pushed greenhouse gas emissions beyond even the worst case scenario. All the evidence one needs that intensity-based targets such as those proposed by Alberta and other jurisdictions are ineffective in achieving real reductions.
