Increasing atmospheric carbon dioxide levels could change the nature of grasslands and decrease their usefulness as grazing pastures, say researchers.
The study was published in the journal Proceedings of the National Academy of Sciences this week (27 August).
If carbon dioxide levels in the atmosphere continue to rise, [...]

Forest in Panama
Rising temperatures over the last few decades in Malaysia and Panama may have decelerated the growth of rainforest trees, according to a study.
This could significantly affect the ability of trees to store carbon dioxide, raising the atmospheric concentrations of this greenhouse gas, say the researchers.
The study is the [...]

Australia Discovers Ocean Current ‘Missing Link’
By Michael Byrnes, Reuters, August 15, 2007
“Australian scientists have discovered a giant underwater current that is one of the last missing links of a system that connects the world’s oceans and helps govern global climate. New research shows that a current sweeping past Australia’s southern island of Tasmania [...]

Missing Carbon Mystery: Case Solved?
By Jane Burgermeister, Nature Magazine, August, 2007 Issue
“[Scientists have long been vexed by] the ‘missing carbon sink’, a billion tonnes of human-generated carbon assumed to be absorbed by northern forests, but unaccounted for in field studies. Scientists now say they have located the missing carbon in tropical forests that [...]

The magnitude of the global carbon sink can be estimated by comparing the rate at which carbon is being emitted into the atmosphere — currently about 7 Gigatonnes a year, which we know from inventories of fossil fuel and biomass burning — with measurements of the [...]

The ocean provides us with food, a prosperous economy and inspiration for all who come near it. But, the effects of global climate change are steadily taking their toll on the health of the ocean.
The ocean and coast are expected to be heavily impacted by climate change. Increased ocean warming, acidification, rising sea levels, [...]
