Scientists say that Technology exists to halt global warming!
The technologies needed to halt global warming for 50 years already exist, according to research published in Science. The study’s authors, Stephen Pacala and Rob Socolow, say implementing them should begin now. The study focuses on the role of carbon dioxide released when fossil fuels such as coal, oil and natural gas are burnt. Carbon dioxide is the main greenhouse gas’ responsible for global warming and efforts to reduce emissions are seen as the main way to address human induced climate change. The researchers identified 15 technologies that either store carbon, or provide energy without producing carbon emissions, or improve the efficiency of carbon-based energy supplies. They say that large-scale use of any one of these has the potential to reduce global carbon emissions by at least one billion tonnes per 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 use of 'biomass' fuels, such as ethanol. Current yearly global carbon dioxide emissions contain seven billion tonnes of carbon. But that figure is expected to double in the next 50 years due to increasing populations and energy demands. Implementing a combination of the technologies could reduce carbon emissions by enough to keep them at today’s levels.
