I have sent an email to Roy asking that I am waiting for his reply as we type.

'While record high temperatures for winter were being measured in the Arctic and the maximum winter sea-ice extent was reached, the sea-ice extent in the Antarctic reached its summer minimum for this year. The especially low amount of Antarctic sea-ice cover this summer meant extremely favourable conditions for the research icebreaker RV Polarstern, whose route took her to the southern Weddell Sea this year. '

While the third story reads

'Usually, at the North Pole the sun doesn’t rise before 20th March and it is the coldest time of the year. But this year, February was extraordinarily warm. Analyses of satellite and station data indicate that very warm air has been advected towards the Arctic, which allowed temperatures to rise until the freezing point'

Which kind of backs up my point that the sea ice is at an all time low, and is getting less every year on average.

re: the temperature, where is that data from? I tried researching it and I can only find reference to it from a University in Alabama, and I can't find what it is actually measuring, it says 'Global lower atmosphere' but what actually is that?

A lot of the heat increase has been absorbed by the oceans and landmasses, so for an accurate record you have to look at something that takes into account those as well. Like the ones NASA has done among others.

the temperature dataset if from UAH satellites https://en.m.wikipedia.org/wiki/UAH_...rature_dataset
Hope this helps explain the datasets

The UAH data set is from NASA satellites.

yes jack but the wiki goes more in depth as to what exactly the satellites are measuring.

Remote Sensing Systems uses the same data. They have excellent explanations of the processes. Remote Sensing Systems

As you know I prefer original sources.
