The March 31, 2014 Intergovernmental Panel on Climate Change (IPCC)’s Report by the world’s international climate experts starkly reminds us that human interference with the climate system is occurring, and climate change poses risks for human and natural systems. Climate extremes are unequivocally caused by human activity.
Acknowledging that human activity is causing extreme conditions in our climate we are lead to ask if humans have the will to keep global temperatures down so that Earth can function at a manageable level. We now understand that greenhouse gas emissions will need to drop by 40 – 70% by 2050. The IPCC Report concludes that actions to effect this change in green house gasses can be brought about without affecting living standards. If we work towards diverting hundreds of billions of dollars from fossil fuels into renewable energy and cutting energy waste, we would shave just 0.06% off expected annual economic growth rates of 1.3%-3%. This investment would save the billions needed to repair losses from extreme climate events. See Summary http://www.climatechange2013.org/images/report/WG1AR5_SPM_FINAL.pdf
“The report is clear “, says EU Commissioner, Connie Hedegaard , ”the more you wait, the more it will cost [and] the more difficult it will become. “
