Record Heat In Antarctica, Claims The Absurd Jonathan Amos

A new record high temperature for the Antarctic continent of +18.3C has been confirmed by the World Meteorological Organization (WMO).

It occurred on 6 February last year at Argentina’s Esperanza research station.

The mark was widely reported at the time but has now been validated by a WMO committee set up to check extreme weather data from around the globe.

The same group rejected an even higher Antarctic claim for 2020 of +20.75C, "recorded" on Seymour Island.

This again received international headlines, but the committee found the sensor set-up incorporated into a Brazilian permafrost experiment had not been properly protected from direct sunlight.


As the report goes on to explain. the record temperature occurred as the result of Foehn winds, which can add several degrees.

The implication is that temperatures like these are not “normal” on the normally frigid Antarctic continent.

In reality temperature of 15C and more are not unusual there, and the previous record of 18.0C was set in 1979:

I personally cannot get worked up about a rise of 0.4C in 41 years! And I certainly would not call 18.4C “heat”.

    The Esperanza Research station was established in 1953, so it’s only the record since 1953, less the effects of equipment changes which account for a lot more than 0.4 degrees.

      Scientists have been studying stratospheric ozone in Antarctica since at least 1957 at three different locations. Warm weather is not unusual. But, did they keep records?

      Which means we have only 30 years of non-CO2 influenced data for comparison, so the claim this is unusual cannot be made.

    Esperanza Base (Hope Bay) is not even within the Antarctic Circle. In fact Reykjavik is nearer the North Pole than this place is to the South Pole. Rejkyavik’s maximum temperature is 30.5°C.

      I must be doing something wrong as my name keeps getting chopped up!

      Exactly. It is located on the island/ continent of Antarctica but it is not IN the Antarctic. It is further from the pole than any part of Iceland is from the North Pole. It is the same latitude south as Trondheim in Norway is north. They deliberately make this stuff sound scary.

      A year last March/April, Das Beeb carried similar ‘disinformation’. We’d nipped into the hut for a cuppa and general blether about river conditions, best prospects etc. when a third rod appeared:

      ‘Record temperatures in Antarctica.Was on the news’, he proclaimed.

      Mention of Foehn winds, Antarctic Circle and record-keeping were met with a vacant glaze…

      Too bad we didn’t get on to THC or AMO or Mr. McIntyre

    Whence cometh the motivation to exaggerate a “problem” by falsely adjusting data?

    Excellent description on German floods here (aside from obligatory climate ref.):

      Did they not build the dam to stop future flooding? If so, heads ought to roll – prison sentences deserved for such a scale of incompetence? Climate change is a convenient get-out-of-jail-free card for the incompetents.

    A momentary temperature in one location barely above previous the high set many years ago? Simply not a thing.

      Would that any in the CCC – or UEA! – WOULD admit as much. And where on Earth are the sceptic MPs in this? Hiding behind their large bank accounts!

    ‘And I certainly would not call 18.4C “heat”.’

    Agreed. Why would you wake the Extremes Committee for 18.4C?

      Indeed temperature is not a metric for heat(aka: Enthalpy). It is as much a metric of volume as this is inversely proportional to temperature in accordance with Charles’ Law.
      This is found in practice when we refer to “Wind Chill”.

        Interesting. Should temperature be reported with barometric pressure*? Is there a metric that combines the two?

        *Which isn’t even reported factually. Published pressure numbers are adjusted for elevation.

    Can we send Jonathan down there for a 6 month tour?
