So far, 2010 is warmest ever in recorded history

Year 2010 proves to be the warmest ever in history, the first four months reporting an average temperature of 13.3 degrees centigrade which is 0.69 degrees over the 20th century average.

The combined global land and ocean surfaces temperatures for the period between January and April were the warmest ever recorded, and April was the hottest single month ever, "says U.S. climate agency in its final report.

The total global April land and sea mean surface temperature was the warmest ever recorded at 14.5 degrees Celsius (58.1 degrees F).

It is 0.76 degrees Celsius over the 20th century average of 13.7 degrees Celsius, "said National Park Service (NOAA).

Earth's temperature from January to April at 56.0 degrees Fahrenheit (13.3Â ° C) is 1.24 degrees Fahrenheit or (0.69Â ° C) over 20 century average states.

While the global ocean surface temperature was 0.57 degrees Celsius over the 20th century average of 16 degrees and the warmest on record for April, the global land temperature 1.29 degrees Celsius over the 20th century average of 8.1, the third warmest on record for April.

The report says that the heat was most pronounced in the equatorial part of the great oceans, especially in the Atlantic.

Warmer than normal-dominated world, with the most prominent heat in Canada, Alaska, Australia eastern United States, South Asia, North Africa and northern Russia.

Cooler than normal places including Mongolia, Argentina, Russia's Far East, the western contiguous United States and much of China, it said.

El Nino Southern Oscillation (ENSO), a climate pattern that occurs over the tropical Pacific Ocean, on average, every five years, weakened in April, as the sea-surface temperature anomalies into the equatorial Pacific.

The climate pattern is known for its connection with floods, droughts and other weather disturbances in many world regions, which vary with the individual events.

Fading made significant contributions to the heat observed in the tropical belt and warmth of the total ocean temperatures for April.

According to NOAA's Climate Prediction Center, El Nia ± o is expected to continue through June.

The agency said the Arctic sea ice was below normal for the 11 in a row in April and 2.1 percent above the average level from 1979 to 2000. It was the largest Arctic sea ice since April 2001.

Moreover, satellite observations showed snow cover extent was the fourth lowest recorded since 1967.
