A new study led by UC Berkeley Lab researcher Trevor Keenan suggests that increased plant growth is slowing the accumulation of carbon dioxide in the atmosphere, a finding that could help explain the mystery of why the uptick in CO2 concentrations has leveled off since 2002, even as emissions have increased. “We believed one of the planet’s main carbon sinks had unexpectedly strengthened,” Keenan explained in a Lab press release. “The question was: which one?” Read more about Greening the Planet: The Fertilizer Effect of CO2 Slows Warming »
In the mid-2000s, William Fisk, a senior scientist at Lawrence Berkeley National Laboratory, stumbled upon two obscure Hungarian studies that challenged common assumptions about the air indoors. The studies suggested that, even at relatively low levels, carbon dioxide could impair how well people thought and worked.

For the past ten years, Peidong Yang has been trying to make like a tree. Yang, a professor in UC Berkeley’s Department of Chemistry, researches artificial photosynthesis, a process that mimics a leaf’s ability to convert sun, water, and carbon dioxide into fuel. But in his case, the fuel isn’t glucose—it’s gasoline. Read more about Reverse Cycle: Inspired by Leaves, a New Invention Turns Sunlight and Water into Fuel »
No wonder so many scientists are at their wits’ end when it comes to climate change: Despite an overwhelming scientific consensus that the planet is warming—and that human activity is much to blame—the public remains skeptical. In fact, one poll indicates that nearly 2 out of 5 Americans believe global warming is just a hoax.
Not to mention that some of those climate change deniers are member of Congress. Read more about Cliffs Notes for Climate Change? Science Panels Create a Primer on the Planet's Fate »
