World Bank Report Predicts 4°C Temperature Increase

Business as usual will cause temperatures to rise by 4°C by 2060. If we fail to act on to reduce global warming causing GHG emissions we can expect food shortages, extreme weather and sea-level rise. These are the finding of a World Bank report published on November 19, 2012. The report is titled Turn Down the Heat: Why a 4°C Warmer World Must be Avoided. It predicts that sea-levels could rise by more than a meter by 2100.

As a direct corollary of a 4°C world we can expect more flooding in cities, as well as increasingly intense tropical storms, droughts and extreme rainfall. These affects will further damage ecosystems, and cause more species to go extinct.

The Safe Upper Limit of Atmospheric Carbon is 350 PPM

As reviewed at 350.org, the science is clear, global warming is happening faster than ever and humans are responsible. Global warming is caused by releasing greenhouse gases (GHGs) into the atmosphere. The most common greenhouse gas is carbon dioxide. Global warming destabilizes the delicate balance that makes life on this planet possible. Just a few degrees in temperature can completely change the world as we know it, and threaten the lives of millions of people around the world. The planet is in peril because we've poured too much carbon into the atmosphere, and we already seen troubling signs including extreme weather and melting ice caps.
