The Big Suck: Can Atmospheric Carbon Removal Stop Climate Calamity?

Strategies to deal with climate change have focused largely on reducing emissions of CO2 and other planet-warming compounds from industry, transportation and agriculture. The news isn’t particularly heartening on that front. After three years of leveling off, CO2 levels are expected to rise by two percent by the end of 2017, due largely to increased coal-burning in China.

Greening the Planet: The Fertilizer Effect of CO2 Slows Warming

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?”

Straw Into Gold: New Way to Retrieve CO2 From Air and Recycle It Into Useful Products

Turning an undesirable substance into something valuable seems like the plot of an old fable, but UC Berkeley researchers Chris Chang and Omar Yaghi may have done just that. Their invention, covalent organic frameworks, or COFs, can transform atmospheric carbon dioxide into a useful building block for biodegradable plastics, fuel, and more.

Chang likens COFs to TinkerToys, though at a nano scale. They consist of strings of carbon crystals that are special in their unique porosity, as they can be custom tailored to capture the chemical of choice.

As Illicit Pot Farms Resort to Rat Poison, They Are “Wiping Out” Wildlife Populations

A recent article in Mother Jones magazine calculates the impact of the illicit marijuana trade on global warming, and arrives at some pretty grim conclusions. U.S. dope production and distribution, the piece notes, emit as much atmospheric carbon as 3 million cars. In California, indoor grows suck up 9 percent of household electricity; outdoor plots consume more water than does the city of San Francisco.
