Global climate trend since Nov. 16, 1978: +0.13 C per decade
February temperatures (preliminary)


Global composite temp.: +0.20 C (about 0.36 degrees Fahrenheit) above 30-year average for February.
Northern Hemisphere: +0.24 C (about 0.43 degrees Fahrenheit) above 30-year average for February.
Southern Hemisphere: +0.15 C (about 0.27 degrees Fahrenheit) above 30-year average for February.
Tropics: +0.03 C (about 0.05 degrees Fahrenheit) above 30-year average for February.
January temperatures (revised):

Global Composite: +0.26 C above 30-year average
Northern Hemisphere: +0.46 C above 30-year average
Southern Hemisphere: +0.06 C above 30-year average
Tropics: – 0.26 C below 30-year average
(All temperature anomalies are based on a 30-year average (1981-2010) for the month reported.)
Notes on data released March 2, 2018:

Compared to seasonal norms, the coldest spot on the globe in February was in northern Manitoba, Canada, near the Caribou River Park Reserve. Temperatures there were 5.95 C (about 10.71 degrees Fahrenheit) cooler than seasonal norms.

Compared to seasonal norms, the warmest place on Earth in February was northwest of Wrangel Island, in the East Siberian Sea. Tropospheric temperatures there averaged 6.89 C (about 12.40 degrees Fahrenheit) warmer than seasonal norms.

As part of an ongoing joint project between UAH, NOAA and NASA, Dr. John Christy, director of the Earth System Science Center at The University of Alabama in Huntsville, 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 are collected and processed, they are placed in a “public” computer file for immediate access by atmospheric scientists in the U.S. and abroad.
The complete version 6 lower troposphere dataset is available here:

Archived color maps of local temperature anomalies are available on-line at:

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.

Dr. Roy Spencer adds from his website:

The Version 6.0 global average lower tropospheric temperature (LT) anomaly for February, 2018 was +0.20 deg. C, down a little from the January value of +0.26 deg. C:

Global area-averaged lower tropospheric temperature anomalies (departures from 30-year calendar monthly means, 1981-2010). The 13-month centered average is meant to give an indication of the lower frequency variations in the data; the choice of 13 months is somewhat arbitrary… an odd number of months allows centered plotting on months with no time lag between the two plotted time series. The inclusion of two of the same calendar months on the ends of the 13 month averaging period causes no issues with interpretation because the seasonal temperature cycle has been removed, and so has the distinction between calendar months.

The global, hemispheric, and tropical LT anomalies from the 30-year (1981-2010) average for the last 14 months are:

YEAR MO GLOBE NHEM. SHEM. TROPICS
2017 01 +0.33 +0.31 +0.34 +0.10
2017 02 +0.38 +0.57 +0.19 +0.08
2017 03 +0.23 +0.36 +0.09 +0.06
2017 04 +0.27 +0.28 +0.26 +0.21
2017 05 +0.44 +0.39 +0.49 +0.41
2017 06 +0.21 +0.33 +0.10 +0.39
2017 07 +0.29 +0.30 +0.27 +0.51
2017 08 +0.41 +0.40 +0.42 +0.46
2017 09 +0.54 +0.51 +0.57 +0.54
2017 10 +0.63 +0.66 +0.59 +0.47
2017 11 +0.36 +0.33 +0.38 +0.26
2017 12 +0.41 +0.50 +0.33 +0.26
2018 01 +0.26 +0.46 +0.06 -0.12
2018 02 +0.20 +0.24 +0.15 +0.03

The linear temperature trend of the global average lower tropospheric temperature anomalies from January 1979 through February 2018 remains at +0.13 C/decade.
