Pathways to stopping climate change – report from UN Climate Summit

Efficiency, renewables, biofuels key to stopping climate change ABC News 14 July 14  The positive message from a scientific report for the UN Climate Summit is that the tough task of cutting greenhosue gas emissions to limit global temperature rise to below two degrees is definitely achievable by following a set of bold, practical steps

The 15 national pathways examined in the report all show the importance of three factors for achieving radically lower carbon emissions.

The first is greatly increased efficiency and conservation in all energy use.

The second factor is taking the carbon out of electricity by using renewable sources, “such as wind and solar, as well as nuclear power, and/or the capture and sequestration of carbon emissions from fossil-fuel burning”.

Nuclear energy still attracts widespread and determined opposition, and carbon capture and sequestration (trapping CO₂ emissions and storing them underground or beneath the sea floor) has not yet proved that it can work on a commercial scale.

The third factor involves replacing fossil fuels in transport, heating and industrial processes with a mix of low-carbon electricity, sustainable biofuels, and hydrogen…… http://www.abc.net.au/environment/articles/2014/07/14/4045481.htm
