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:

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.

The Arctic ice is not refreezing
