Notes on data released Jan. 3, 2014:
2013 was the fourth warmest year in the satellite era, trailing only 1998, 2010 and 2005, according to Dr. John Christy, a professor of atmospheric science and director of the Earth System Science Center at the University of Alabama in Huntsville. The warmest areas during the year were over the North Pacific and the Antarctic, where temperatures for the year averaged more than 1.4 C (more than 2.5 degrees Fahrenheit) warmer than normal. There were small areas of cooler than normal temperatures scattered about the globe, including one area over central Canada where temperatures were 0.6 C (about 1.1 degrees Fahrenheit) cooler than the 30-year norm.

Compared to seasonal norms, in December the warmest area on the globe was the northeastern Pacific Ocean, where the average temperature for the month was 4.91 C (about 8.8 degrees F) warmer than seasonal norms. The coolest area was in central Manitoba, near Lake Winnipeg, where temperatures in the troposphere were 5.37 C (almost 9.7 degrees F) cooler than seasonal norms.
Archived color maps of local temperature anomalies are available on-line at:
As part of an ongoing joint project between UA Huntsville, 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.

Given that we appear to be at the top of a well observed 60 year cycle then this is not unexpected. The real question is ‘How much down from here do we go and for how long?”.
It’s always interesting to see the global perspective since it averages out local events such as the current deep freeze in the Midwest and the severe heat wave in Australia, which can be misleading is viewed in isolation.
The point is Richard, the trend remains upwards.It may be a small amount, but it is still rising, not falling or staying still. Is there any objective evidence that we are at a peak and the trend will reverse?

Well the HadCrut4 says there is a 60 year and we are at the top of it.
The UAH says the same (though with only data since 1979 you can only see half a cycle).
What evidence do you have that this is an upward trend? It looks very, very cyclic to me.
Someone forgot to tell Winnipeg. We had the 6th coldest December on record, coldest since 1933 and New Years Eve hit -48 with the wind chill.
I hear we made headlines across Canada.
But that’s not climate. That’s weather. It’s only climate when it’s hot.
We have been told that 2013 was the hottest year ever in South Australia. I would like to see where they take the readings!
In the future, my sea surface temperature updates will likely be a little later than what we’re used to. But here’s the preliminary December 2013 update:

It sure missed us!
Our local weather station in Kent reports that 2013 was 0.37 degrees C below 28 year average.
re: 2013 was 4th warmest year in the satellite era
Not getting what we ‘paid for’ in Texas; this has been one of the coldest winters we’ve seen! We’ve had low temps in the teens and snow and ice on two occasions already, and it’s only the 3rd of January!
Give me my warming!!!
/mild sarc (as if this tag is needed)
NEW TECH (system of measurement) 1979 to 2013
0.27 of 1 degree to the positive (can you feel 0.27 or even 2.7)?
what is a global average?
compare this with a 50, 100, 200, 600, 1000 year global average
this is who peed in the pool
this is calculating your gas mileage for a trip across North America by using the data from the first three blocks
there’s very little variation outside of 0.8 °C for 34 years
this is from a satellite(s) how many miles above the earth?
whats the error in the equipment?
Whats the error in the atmosphere?
This is rolling a die seven times and getting 1-2-3-4-5-6-5 and saying its skewed to 5
Honey can you turn down the furnace 0.27 degrees the house is getting really really warm.
Oh no the hot tub hit 39.27°C way way to hot now (must be broken)
Sorry kids school is cancelled today because the windchill is -25.27°C you would absolutely freeze.
I better sue McDonalds my coffee was served at 82.49°C rather than the 82.22°C (180°F) specified.
Remember when the planet warmed 0.8°C and the Ice Age ended?
Why don’t people get how absolutely ludicrous this data is in the perspective of global history.
One thing that I wonder about is “What is Zero.” Is there an agreed to value for “Normal?”
I find that very hard to believe, quite frankly – 2013 being the 4th warmest year in the last 30 years. I demand a recount, or, perhaps the coolists should be given opportunity to “adjust” the figures, this time, eh?
As a side note to Justin Hoffer’s point, the temperatures that were reach in Winnipeg were actually equivalent to the temperature on Mars, a planet millions of miles further from the sun then we are.
These massive flucuations in temperature and increases in nature disasters HAVE to be a wake up call do they not? Has the human race had enough? How much more do we have to experience to completely wipe out the denial of climate change? Furthermore how much more do we have to endure until we finally change our ways?

“The point is Richard, the trend remains upwards”
The entire 34 year variation cannot constitute a “TREND” in the perspective of the planet. This is absolutely ZERO information. (perhaps its giving us variation parameters)
perspective people perspective
Go to the hardware store, pull out every single thermometer and see what the variation is.
There you have it … 2013 was the 4th warmest year in the satellite era. And with people sure to try to spin it to a particular belief, let me just add that this incontrovertibly proves that 2013 was the 4th warmest year in the satellite era. And that’s all. This still says nothing about future trends, no matter one’s wishes, hopes, or fears.
@gareth.
@richard.
Normally scientists would wait and collect 60 years worth of data before discussing whether the current anomaly was above or below the normal trend. If the trough of a 60 year cycle occurred in the 70s or 80s then we are just past the peak and should still expect positive anomalies (above mean of trend) for a number of years. We should be able to remove the 60 year cycle after 2040 or so. Until then we’re just guessing either way.
Or a simpler way is to tell us what the amplitude of the 60 year cycle is so that we can remove it.
Is mean global average temperature data available, rather than just the anomaly? I’d be interested to know the trend for the actual average global temperature over the years.
It looks like it’s with a December anomaly of 1.577C the tenth warmest year for RSS with 0.218 C above their average

It looks like UAH continues to deviate from the other global temperature datasets. Something seems off.
Who’s the coolest “coolist?
Having that heat in the atmosphere above the north Pacific is a net cooling effect to the planet as the ocean heat passes through the air before making its way back the the dark regions of the universe. People are viewing this as a bad thing – I don’t understand that. Rejoice, people – that is what global cooling looks like.
