Plants may not protect us against climate change
Posted by Science Now: None Given on April 20th, 2015
Science Now: Plants are one of the last bulwarks against climate change. They feed on carbon dioxide, growing faster and absorbing more of the greenhouse gas as humans produce it. But a new study finds that limited nutrients may keep plants from growing as fast as scientists thought, leading to more global warming than some climate models had predicted by 2100.
Plants need different nutrients to thrive, such as nitrogen for making the light-absorbing pigment chlorophyll and phosphorus for building proteins....

Genetically Engineered Bacteria Could Help Fight Climate Change
Posted by Science Now: None Given on February 26th, 2012
Science Now: As humans warm the planet by releasing carbon dioxide into the atmosphere, some researchers believe that capturing CO2 and trapping it in buried rocks could lower the risk of catastrophic climate change. Now a team of researchers has shown that bacteria can help the process along. They can even be genetically modified to trap CO2 faster, keeping it underground for millions of years.
When CO2 is pumped into underground porous rocks, it combines with metal ions in the salty water that fills the...
