Temperature for October 2015 exceeded 1°C, the hottest it has been since 1880. This makes this year the warmest ever recorded.

According to Daily Mail the last month's global average surface temperatures were 1.04°C more than the long-term average. This is the biggest increase of any month recorded. The last biggest change was in January 2007, which was 0.97°C.

Meanwhile, The Washington Post reported that the Japan Meteorological Agency and NASA's latest data shows that the October heat beat the records of last year's temperatures. October 2015's recorded heat is higher than October 2014's heat by 0.34 degrees according to JMA and 0.32 degrees according to NASA's analyses.

Sci-Tech Today reported that important locations in the Pacific Ocean have reached temperatures warmer than they were during the scorching 1997 El Niño record. The recorded heat led scientists to believe that this year's heat could beat the 1997 El Niño record.

"This thing is still growing and it's definitely warmer than it was in 1997," NASA's Jet Propulsion Laboratory climatologist Bill Patzert said. "It (temperature readings) has now bypassed the previous champ of the modern satellite era -- the 1997 El Niño has just been toppled by 2015."

NASA Goddard Institute for Space Studies director Gavin Schmidt said, "Probability that 2015 will be a record warm year now 99.9 per cent based on Jan-Oct GISTEMP data."

Experts also expect this year to end with global temperatures reaching 1°C above pre-industrial levels. Some scientists believe that this year's summer temperature could be the hottest the globe has been since 4,000 years ago.

Abnormally high temperatures have been experienced in northeast Africa, certain parts of Southeast Asia, the Middle East, and a few parts of North and South America. Some of the cooler parts of the world were recorded in the tip of South America, western Canada, Alaska, and certain parts of Central Asia.
