Warmest October in the Satellite Temperature Record

05.11.2015

Global Temperature Report: October 2015

Warmest October in the satellite temperature record




Warmest October in the Satellite Temperature Record

UAH

Global climate trend since Nov. 16, 1978: +0.11 C per decade

October temperatures (preliminary)

Global composite temp.: +0.43 C (about 0.77 degrees Fahrenheit) above 30-year average for October.

Northern Hemisphere: +0.64 C (about 1.15 degrees Fahrenheit) above 30-year average for October.

Southern Hemisphere: +0.21 C (about 0.38 degrees Fahrenheit) above 30-year average for October.

Tropics: +0.53 C (about 0.95 degrees Fahrenheit) above 30-year average for October.

September temperatures (revised):

Global Composite: +0.25 C above 30-year average

Northern Hemisphere: +0.34 C above 30-year average

Southern Hemisphere: +0.17 C above 30-year average

Tropics: +0.52 C above 30-year average

(All temperature anomalies are based on a 30-year average (1981-2010) for the month reported.)

Notes on data released Nov. 3, 2015:

Powered by an El Niño Pacific Ocean warming event, temperatures in October set records globally, in the Northern Hemisphere and the Tropics, while temperatures in the Southern Hemisphere pushed toward the upper end of the dataset, said Dr. John Christy, director of the Earth System Science Center at The University of Alabama in Huntsville. October 2015 was the warmest October in the 36-year satellite temperature record, pushing past October 1998 during what was then called the El Niño of the Century.

In the Northern Hemisphere, October 2015 registered the third largest deviation from seasonal norms in the 443 month satellite temperature record, making it the third “warmest” month in the Northern Hemisphere since December 1978. October 2015 trailed only April 1998 (+0.85 C) and February 1998 (0.69 C) as the “warmest” month in the Northern Hemisphere.

“We thought this El Niño had the potential to be a record setter for some of the quantities we track, and it isn’t disappointing,” Christy said. “Not only is this a strong El Niño, but the transient warming we see from it is superimposed on top of the slowly rising global base temperature. The satellite temperature dataset shows an overall warming of about 0.39 C during the past 36 years. Put a strong El Niño on top of that and we shouldn’t be surprised at what we saw in October.”

Compared to seasonal norms, the warmest average temperature anomaly on Earth in October was over east Antarctica in Queen Maud Land. The October temperature there averaged 3.97 C (about 7.15 degrees F) warmer than seasonal norms. Compared to seasonal norms, the coolest average temperature on Earth in October was southwest of New Zealand on the edge of the southern ocean, where the average October 2015 temperature was 3.33 C (about 5.99 degrees F) cooler than normal.

As part of an ongoing joint project between UAHuntsville, NOAA and NASA, Christy and Dr. Roy Spencer, an ESSC principal scientist, use data gathered by advanced microwave sounding units on NOAA and NASA satellites to get accurate temperature readings for almost all regions of the Earth. This includes remote desert, ocean and rain forest areas where reliable climate data are not otherwise available.

The satellite-based instruments measure the temperature of the atmosphere from the surface up to an altitude of about eight kilometers above sea level. Once the monthly temperature data is collected and processed, it is placed in a "public" computer file for immediate access by atmospheric scientists in the U.S. and abroad.

Neither Christy nor Spencer receives any research support or funding from oil, coal or industrial companies or organizations, or from any private or special interest groups. All of their climate research funding comes from federal and state grants or contracts.

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
