Rising carbon dioxide boosts plant growth but reduces key nutrients, weakening global food quality and crop nutrition.

As greenhouse gas concentrations in the air continue to climb, plants are faced with a ... a growing body of evidence that the carbon dioxide-triggered increase in photosynthesis, known as the carbon ...

One reason tropical forests could be absorbing substantially more carbon dioxide than accounted for in the models is the phenomenon known as CO 2 fertilization. Trees take in carbon dioxide to ...

By 2050, atmospheric concentrations of CO2 will be 40 per cent higher than today’s levels if current trends continue, at roughly 570 parts per million (ppm). Many of today’s trees will still ...

“During the daytime, trees are taking up something like 60% of the fossil fuel CO2 that's being emitted,” said USC professor William Berelson. Recent data from air quality sensors placed ...
