The technologies to halt global warming for 50 years already exist, according to research published this week in the journal Science. The study’s authors, Stephen Pacala and Rob Socolow, say that implementing them should begin immediately.
The researchers identified 15 technologies that store carbon, provide energy without producing carbon emissions or improve the efficiency of carbon-based energy suppliers. They say the large-scale use of any one of any of these has the potential to reduce global carbon emissions by at least one billion tons a year by 2054.
Options available include renewable energy sources such as wind and solar power, switching of fuel from coal to nuclear or natural-gas supplies, storage of carbon dioxide produced by power plants, more efficient use of car fuel and electricity, increasing the global forested area, and the use of “biomass” fuels, such as ethanol.
