ABC News Australia—March 14, 2012
In their annual State of the Climate report released in March 2012, Australian researchers indicated that annual daily maximum temperatures increased dramatically since 1910. Dr. Karl Berganza of Australia’s Bureau of Meteorology had expressed concern at the alarming pace of climate change. He added, “In the geological history of the earth, global changes of this magnitude happen very rarely. We have no evidence going back 800,000 years of CO2 levels above 300 parts per million.”
Fast forward a year later and the world saw CO2 levels hit a record-shattering 400 parts per million in April 2013.
