Environmental decontamination, greenhouse gases, and the genome of a methane-loving bacterium
Mention greenhouse gases
to most people and they're apt to think of carbon dioxide, fossil fuels, and big cars. Though carbon dioxide emissions are the major source of greenhouse gases, methane is far more effective at trapping heat in the atmosphere. Like increasing carbon ...

Do genes respond to global warming?
...l Panel on Climate Change predicts that greenhouse gases
will increase global temperatures by 3.6 degrees F by 2100--a rise unprecedented over the past 10,000 years. While the effects of climate change on species' geographic range and population dynamics are increasingly understood, scientists know little ...

Plankton may influence climate change says UCSB scientist
