The UK Met Office has concluded that t that 2012 is very likely to be between the 4th and 14th warmest year in a record dating back to 1850. Due to a La Niña through the first part of the year, 2012 is shaping up to be cooler than the average for the past decade.
Dr. Peter Stott, Head of Climate Monitoring and Attribution at the Met Office, said: “Although the first decade of the 21st century was the warmest on record, warming has not been as rapid since 2000 as over the longer period since the 1970s.
“This variability in global temperatures is not unusual, with several periods lasting a decade or more with little or no warming since the instrumental record began. We are investigating why the temperature rise at the surface has slowed in recent years, including how ocean heat content changes and the effects of aerosols from atmospheric pollution may have influenced global climate.”
Final figures for the whole of 2012 will be available in March 2013.
