Could this rock save the planet?

Olivine may be kryptonite for climate change, but it fights CO2 as only a mineral can -- incredibly slowly.


Instead of hacking the planet, should we hack our babies?

S. Matthew Liao, a philosopher and bioethicist, has some incredible ideas about how to deal with climate change. Instead of resorting to geoengineering, he suggests, why not consider engineering humans to cause less damage to …

Don’t believe the hype about the ‘molecule that could solve climate change’

Some chemists came up with a really clever way to observe the intermediate stage of an atmospheric chemical reaction, and then some PR flack got a hold of it and suddenly science has invented a brand-new molecule that will solve all our climate change woes! As usual, things that seem too good to be true probably are.

That's the question Montgomery Burns has often asked, and one that scientists in the UK will begin to answer this October when they will use a weather balloon to loft a hose a little more than half a mile into the sky. They'll then pump water up the hose into the atmosphere. If that sounds simplistic to you, maybe you just don’t understand science.
