The world lost record amounts of Arctic sea ice in 2012 and spewed out all-time high levels of greenhouse gases from fossil fuel burning, international climate scientists said Tuesday.
Overall, 2012 was among the top 10 on record for global land and surface temperature, said the State of the Climate report issued annually by researchers in Britain and the United States.
"Globally-averaged, 2012 ranked as the eighth or ninth warmest year since records began in the mid-to-late 1800s, according to four independent analyses," said the report.
"The year was 0.14 degrees Celsius - 0.17 degrees Celsius above the 1981-2010 average, depending on the dataset considered."
When it came to Arctic sea ice, a new record low was observed in September for sea ice and another all-time low for snow cover was observed in the Northern Hemisphere, it said.
