Is it game over for the climate yet? Media over-excitement takes off again.

The great sleeping giant that is Antarctica that — apart from the Antarctic Peninsula — refuses to respond to global warming may just have begun to stir, and the implications are, well, apocalyptic, jokes Dr David Whitehouse @ Net Zero Watch.
According to CNN “Antarctic sea ice hits record lows again. Scientists wonder if it’s “the beginning of the end.” CNN also reports that, “90% of ice around Antarctica has disappeared in less than a decade.”
CNN are not the only media outlets to report on this years’ record low sea ice around Antarctica in apocalyptic terms, other media extremists are available.
For Sky News it’s the accelerating melt of polar regions. For the BBC “There is now less sea-ice surrounding the Antarctic continent than at any time since we began using satellites to measure it in the late 1970s.” All this is technically true, but misleading. When it’s put into context one sees a different picture.
So let’s have a look at the actual satellite data of Antarctic sea ice collected monthly since 1979. The NSIDC gives two data sets for what it calls i) sea ice extent, and ii) sea ice area. So let’s examine both of them.
The first graph is sea ice area, the second sea ice extent [see here].
From the empirical data it is evident that there is hardly any change of sea ice over the 44-year time span. Since 2016 there is a dip with possibly more variability (of which more later), and the lowest month (February) does show a record low, but by hardly anything (and also look at the data for 1992).
Does this actual data look like the beginning of the end to you? Where is CNN’s 90% loss or Sky News acceleration?
Antarctic sea ice evolution has no significant trends along the whole period, but a volume drop is observed since 2016.

Of sea ice hype? 🙄
let’s get to the part where they are finding sub tropical plants under the retreating glaciers

Did they forget to mention the rather large number of undersea volcanoes at the edge of the land?
So a data set that has only 45 February’s in it has a record February. Big deal. Do we have record warmth in Antarctica this February? I don’t think so. Record global warmth? Definitely not. Record sea temperature? Not as far as I know.
So I’m going with other causes.
Recent growth and sudden declines in Antarctic sea ice to be unique changes since the early 20th century
Research paints a dramatic first-ever picture for weather and climate implications on the world’s southernmost continent

“The causes of these changes — the decline in the 20th century, the increase after 1979, and the rapid decline in 2016 — are all yet to be precisely determined. But what we’re seeing is something pretty dramatic going on recently.” [bold added]

Nothing to do with hundreds of volcanoes under the sea ice? Hmmmmm.
