Climate change is predicted by the Commonwealth Scientific and Industrial Research Organisation (CSIRO) to have significant effects on the climate of and extreme weather events in Australia, increasing temperatures and the likelihood of heat waves. According to the Bureau of Meteorology, Australia's annual mean temperature for 2009 was above the 1961–90 average, making it the nation's second-warmest year since high-quality records began in 1910. Summers in 2013 and 2014 continued this trend of record-breaking heat—2014 was Australia's third-hottest year on record and 2013 broke national records.
