Geoengineering Projects That Could Offset Global Warming

Geo-engineering is the large-scale engineering of the environment to combat the effects of climate change -- in particular to counteract the effects of increased carbon dioxide in the atmosphere. A number of schemes have been suggested including nutrient fertilisation of the oceans, cloud seeding, sunshades in space, stratospheric aerosol injections, and ocean pipes. The first comprehensive a

However, a new study from Lawrence Livermore National Laboratory, led by atmospheric scientist Govindasamy Bala,

Can We Offset Global Warming By Geoengineering The Climate With Aerosols?

Geoengineering our climate is not a 'quick fix'

The deliberate, large-scale intervention in the Earth's climate system is not a "quick fix" for global warming, according to the findings of the UK's first publicly funded studies on geoengineering.
