The state's program will be able to test the theories about whether cap-and-trade reduces pollution without destroying businesses. If it works, expect other states to quickly follow.
Jamming carbon deep underground has long been a proposed solution to our emissions problems, but it's expensive and rarely used. Now we can use the Earth's heat to make that gas work for us.
Clean power from the Earth used to use a lot of water. But a new discovery means that water can be replaced with CO2, which gets left in the ground and doesn't alter the climate.
Scientists at CalTech are developing a technique that converts water, air, and sunlight into different kinds of fuel that could power everything from car engines to fuel cells in cell phones. It sounds almost too good to be true.
If we continue to burn coal, oil, and gas until resource depletion forces the switch later on, our emissions will drag the Earth back into a primeval super-warm state. But that doesn't have to happen.
Last month, MIT's Climate CoLab announced the Collective Intelligence Climate Contest, a competition that asks entrants to design an international climate agreement. Now it's up to the wisdom of the crowd to pick the best entry.
The lake's lethal combination of methane and carbon dioxide has residents fearing for their lives, but it's also the country's most vital and promising energy source.
