A new study challenges the longstanding view that biofuels are carbon-neutral, and asserts that in the U.S. to date, they have done more harm to the climate than gasoline.
To create accurate models that predict how ice sheets and oceans will react to changing climate, modelers need precise current data. One researcher heads to the ends of the earth to collect just that.
