October: maintaining the warming trend for 2014

September broke global temperature records and October was pretty close behind, recent data from NASA and the Japanese Meteorological Agency (JMA) confirm.

According the the JMA, October was the hottest month on record with a 0.6°F above the 1981-2010 average. This was preceded by the hottest September, August, June and March-May.

NASA Goddard Institute for Space Studies (GISS), which uses a different baseline of 1950-1980, recorded October global temperature as 1.4°F above the average.

According to NASA data, although October did not break monthly temperature records, it tied with 2005 as the warmest October since 1880.

Significantly, both datasets exhibited similar temperature hotspots.

Far eastern Siberia was 10°F hotter than average, and western Europe, northern Africa and western North America were 7°F above normal.

The National Oceanic and Atmospheric Administration (NOAA) confirmed that the contiguous US had its fourth warmest October on record at 3.0°F above the 20th century average.

2014 set to break records

A warm October is maintaining 2014’s warming trend, as January to September 2014 is tied with 1998 as the warmest year on record.

This is despite the fact that El Niño has yet to make an appearance which increases the likelihood of warmer ocean and global temperatures.

NOAA predicts a 3 in 5 chance of El Niño developing this winter and lasting until Spring 2015.

With the warmest 10 years on record occurring since 1998 and 2014 about to hit a new high, the evidence mounts that climate change has arrived and cannot be ignored.
