Much higher-than-normal temperatures at the North Pole

Much higher temperatures at the North Pole at the end of the melt season

These are the temperature anomalies measured at the North Pole for the past seven days.

I have taken a slightly different tack on this and used a layer available on NASA Worldview for ice surface temperature which indicates those areas which are cloud-free as well as measuring the temperatures in degrees Kelvin.

This is how it looks for 5 October, 2018.

The temperatures are given a colour coding which is available in the inset as well as the actual temperatures (in degrees Kelvin) where I point to cursor.

I have taken temperature readings on as close to the same date for each year from 2000 to 2018.

These figures are usually available as a range but for simplicity I have taken a minimum temperature measurement as close to the North Pole as I can.

These figures are therefore necessarily indicative and approximate.

What they do show is that with the exception of one year - 2010 - the minimum temperature at the North Pole is over TWICE  the minimum temperatures measured for other years.

Apart from the one year, 2010, the range of minimum temperatures was, on average from the mid-20's minus (approximately -13F) to over minus 30 degrees Celsius (-22F)

Yesterday I measured the temperature at the Pole as minus 9 Celsius (16F) with a minimum of minus 12 Celsius (10F)

Here are the figures: 

YEAR	MIN TEMP DEG KELVIN	MIN TEMP DEG CELSIUS
2018	261	-12
2017	248	-25
2016	251	-22
2015	245	-28
2014	250	-23
2013	246	-27
2012	242	-31
2011	241	-32
2010	241	-32
2009	263	-10
2008	245	-28
2007	245	-28
2006	253	-20
2005	223	-50
2004	240	-33
2003	244	-29
2002	259	-14
2001	234	-39
2000	223	-50

And here is a representation for two previous years.

Despite the lack of a record in sea ice extent these figures point to a major departure from previous years.
