The monthly climate report, issued by the National Oceanic and Atmospheric Administration (NOAA), shows that 2015 will be Earth’s warmest recorded year.

The Washington Post reports that the average temperature for this year, through October, is around 1.55 degrees above the average in the 20th century. The temperatures for 2015 are averaging around 0.22 degrees above 2014, the prior warmest year recorded.

Gavin Schmidt, a NASA climatologist said Tuesday that there is a “99.9 percent chance” that 2015 will end as the warmest year on record. Out of the 10 months that have passed in 2015, eight have been the warmest on record, according to NOAA.

Analysis from the Japan Meteorological Agency and NASA show similar data, showing that this October was the warmest on record, by a significant margin, of around 0.31 degrees.

According to NOAA, “large regions of Earth’s land surfaces were much warmer than average.” Areas such as south Australia, portions of East Asia, central and south Africa, most of South America, and western North America were the greatest affected.

A strong El Nino event this year caused warmer than average ocean temperatures, causing October ocean temperatures to reach the highest levels recorded. El Nino warms not only the Pacific Ocean, but also releases significant amounts of heat into the atmosphere. This helps push temperatures to record levels. According to NOAA data, every month since 1980 has been above “20th century average.”

The forecast for El Nino expects it to stay strong through the upcoming Winter season. New temperature records are expected through the end of the year.
