The United Kingdom’s Met Office says that 2015 will be the year when average world temperatures rise more than 1 degree C (1.8 F)
above pre-industrial levels. That is halfway to the 2 degrees C temperature increase threshold that scientists say could dangerously destabilize the planet’s climate system. The Met office reported that from January to September this year, global temperatures hit 1.02 degrees C above pre-industrial averages and that temperatures for the full year are virtually certain to be above the 1 C level. Meanwhile, the World Meteorological Association (WMO) reported that atmospheric concentrations of CO2 in 2014 averaged 397.7 parts per million and that average 2015 concentrations could surpass the 400 ppm mark. “We are moving into uncharted territory at a frightening speed,” WMO Secretary General Michel Jarraud said.
