Arctic ocean melting ice
The Arctic ocean melting ice has experienced a record ice melt in the past year, while at the same time increase the emissions of the greenhouse gas carbon dioxide at a historic high. 2012 was also one of the ten hottest years since the beginning of the scientific temperature measurement mid 19th Century was, according to one of the U.S. Agency for Oenology and Atmospheric Administration (NOAA) in Washington presented 260 page study. “The results are striking,” said Kathryn Sullivan, NOAA chief. “Our planet as a whole is becoming a warmer place.”“A large number of observations from the year 2012 confirm the long term trends such as the alarming increase of greenhouse gas emissions, sea level rise of the oceans and Arctic ocean melting ice,” Sullivan added. According to the annual report, the NOAA Climate reduced ice in the Arctic in 2012 to 3.41 million square kilometers. Arctic ocean melting ice is the smallest area since satellite observation of the region 34 years ago and 18 percent less than the previous low record set in 2007.
Records are no exceptions
The Arctic ocean melting ice, according to the study also contributed to an increase in the level of the oceans at. The sea level reached a record high in 2012, and was 3.5 inches above the average for the years 1993 to 2010.In the hottest years since the mid 19th Century is 2012, according to the NOAA study on the eighth or ninth. Depending on the record, it was warmer in 2012 from 0.14 to 0.17 degrees Celsius than the average of 1981 to 2010. the past year were also expelled from the combustion of fossil energy such as oil or coal 9.7 billion tons of Co2 also a record.
NOAA chief Kathryn Sullivan called the annual report “feeling the pulse of the planet“. The report to which 382 scientists cooperated in the world, already summarizes published data, it is also but in a wider context of climate change on Earth for decades.
It is crucial to put together a big picture,” the director of the National Climatic Data Center, Tom Karl said. “The signs we are seeing a warming world.”
Sullivan pointed to “remarkable changes in key climate indicators” such dramatic highs in the heat content of the oceans, a record Arctic ice melt and a large melting Greenland ice last year. The data reported also from highs at sea level.
Stop temperature rise
Karl said, the surface temperatures were not increased in the past 10 years, but that was only a brief snapshot. In a period of 30, 50 and 100 years was to observe quite a climb. Since the beginning of climate records in 1880, the 10 warmest years were higher in the past 15 years, showed NOAA data.2012 was hotter than every year last century except one. In 1998, the El Nino weather phenomenon have provided for a record year. NOAA designates 2010 as the warmest year since recording of weather data.
Karl stressed that there must not be a new record every year. All indicators “sing the same song that we live in a warming world,” he said. Why this was, the report does not cover. “The Arctic ocean melting ice causes are mainly greenhouse gases, the burning of fossil fuels“.
