Adjusting Earth's thermostat, with caution

A vast majority of scientists believe that the Earth is warming at an unprecedented rate and that human activity is almost certainly the dominant cause. But on the topics of response and mitigation, there is far less consensus.

The laws of global warming

With policymakers and political leaders increasingly unable to combat global climate change, more scientists are considering the use of manual manipulation of the environment to slow warming's damage to the planet.

Effects of sea spray geoengineering on global climate

Anthropogenic climate warming is leading to consideration of options for geoengineering to offset rising carbon dioxide levels. One potential technique involves injecting artificial sea spray into the atmosphere. The sea ...

Testing geoengineering

Solar radiation management is a class of theoretical concepts for manipulating the climate in order to reduce the risks of global warming caused by greenhouse gasses. But its potential effectiveness and risks are uncertain, ...

As climate talks drag on, more ponder techno-fixes

(AP) -- Like the warming atmosphere above, a once-taboo idea hangs over the slow, frustrating U.N. talks to curb climate change: the idea to tinker with the atmosphere or the planet itself, pollute the skies to ward off ...
