Ancient forests stabilised Earth’s CO2 and climate
When CO2 levels became too low for plants to grow properly, forests appear to have kept the climate in check by slowing down the removal of carbon dioxide from…
Tropical forest carbon absorption may hinge on an odd couple
The findings suggest that the role of tropical forests in offsetting the atmospheric buildup of carbon from fossil fuels depends on tree diversity,…
Seasonal carbon dioxide range expanding as more is added to Earth's atmosphere
Levels of carbon dioxide in the atmosphere rise and fall each year as plants, through photosynthesis and respiration, take up the gas in spring and summer, and…
Trees Using Water More Efficiently as Atmospheric Carbon Dioxide Rises
The study, “Increase in forest water-use efficiency as atmospheric carbon dioxide concentrations rise,” was published on-line today in the journal Nature. Dave…
Greenhouse gas likely altering ocean foodchain
Climate change may be weeding out the bacteria that form the base of the ocean's food chain, selecting certain strains for survival, according to a new study.In climate change, as in everything, there are winners and losers. As atmospheric carbon dioxide levels and temperature rise globally, scientists increasingly want to know which organisms will thrive and which will perish in the environment of tomorrow….
The chemical memory of seawater
Water does not forget, says Prof. Boris Koch, a chemist at the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association….
