Climate scientists worry about feedbacks, glacial melting, sea level rise, using tax policy to slow warming, and the complexity of climate science. Is it realistic to base our economy on endless growth? What does human behavior tell us about dealing with warming?

Buried charcoal stimulates microbes and plant growth, helping farmers on poor soil. Studies show that charcoal is stable for hundreds of years.

Decay is part of life, and death. When garbage decays in a landfill, or manure decays in a tank, the result is methane. Is this natural gas a problem — or an opportunity?

The candidates are skirting issues related to environment, energy and science policy. Heard promising plans for greener energy, solid science advice, or coping with the decline of oil? We neither…

Plug-in hybrids mean more than just extra spending cash for drivers, though. They could offer a new path through the maze of the electric grid, and help to boost the use of alternative energy.

Hybrid cars and plug-in hybrids boost auto efficiency and reduce pollution, but it’s a long struggle from the idea to the reality.

Migration of songbirds, butterflies, turtles and seals. Where does the natural urge to move originate?

Could carbon storage help control warming? The oil industry already injects CO2 into deep rocks. Is it possible to capture CO2 from coal plants, and pump it deep underground?

How’s a hungry fish supposed to make a living in the shallow water below tropical mangrove trees? Hint: Squirt, squirt!

Coal ash is a giant garbage problem. Should we recycle more ash into concrete? A new process might save cement, rock, and landfill space.
