Tokyo: Due to global warming, the worldwide temperature on land and the sea surface in 2010 rose 0.36 C from the 1971 to 2000 average, marking the second highest increase since comparable data became available in 1891, according to Japanese meteorologists.
The existing record rise is 0.37 C marked in 1998.
The global temperature only on land went up 0.68 C, hitting a new high, the Japan Meteorological Agency said in a preliminary report released yesterday.
Japan`s average temperature rose 0.85 C from the 30-year average, matching the fourth highest since 1898.
The weather agency worked out the figures based on data from January through November, Kyodo news agency reported.
The Japanese meteorologists attributed the rise in the average temperature to global warming caused by emissions of greenhouse gases and a rise in the sea surface temperature caused by the El Nino climate pattern.
Such weather conditions caused warm air to cover mid-latitude areas in the northern hemisphere, the report said.
It said the global temperature climbed by 0.68 C in the past 100 years and Japan`s temperature by 1.15 C during the past century.
The average temperature in some parts of Greenland and Canada in 2010 went up by 4 to 5 C, the report said.
Japan`s average temperature in the June to August summer season in 2010 was the highest ever, but the low temperature in the March to May spring season dragged down the yearly average.
The weather agency compiles the average global temperature on land from data at 1,300 locations in the world and Japan`s temperature at 17 locations from Hokkaido in the north to Okinawa in the south.
Meanwhile, the number of tropical depressions that developed into typhoons in 2010 is expected to stay at 14, the smallest figure since 1951 when comparable data was available, the agency said in a separate report.
The existing low is 16 recorded in 1998. The average number in the 1971 to 2000 period is 26.7.
