Antarctic Sea Ice Dips to Record-Low Extent for Early January

Just two years after shrinking to its lowest extent ever measured, Antarctic sea ice may challenge that record a few weeks from now. This depletion comes just as scientists reported a harrowing sixfold increase in the loss of Antarctic land ice over the last 40 years. Unlike land ice, the loss of sea ice doesn’t contribute to sea level rise in itself, but it could help make some of Antarctica’s land ice more vulnerable (see below).

The extent of ice cover encircling the Antarctic coast began taking a nosedive in December, dropping even more quickly than usual for the time of year (late spring in the Southern Hemisphere). Since December 25, Antarctic ice extent has set calendar-day record lows every day for more than three solid weeks. Satellite-based records from the National Snow and Ice Data Center go back to 1979.


Typically, Antarctic ice reaches its minimum for the year in late February or early March (late summer). As of Monday, January 14, the extent was 3.979 million sq km, which is well below the value of 4.154 million sq km observed on that date in 2017. We still have a few weeks to go before 2019’s extent can challenge the lowest value measured at any time of year: 2.110 million square kilometers, observed on March 3, 2017.

1. Still no link to human activity

 

"Post hoc ergo propter hoc" is NOT a scientific theory,.

Measuring a 4 billion year old activity across a few years is like watching an ant take a step and predicting what direction it will be go for the next month.

AGW meets exactly zero criteria for a Scientific Theory (ability to generate revenue for researchers is NOT a criterion). If it was science there would be one model and it would be predictive.

2. A few questions

1. How is the 1979-2019 sea ice extent representative of sea ice extent in decades or centuries past?
2. How is a 30 year period indicative of long term trends going forward decades or centuries in the future?

4. What's happening now

is a pretty big departure from the past. The heat is new. The oceans are brimming with it and things are starting to die. Seabird populations are crashing all around the globe. Fish runs are in trouble. Fish are dying for lack of thiamine. We're pumping our aquifers dry in China, India, the Middle East and the Great Plains.

It's not complicated. We've broken the environment we depend on to live. The seas are choking on heat and carbon. Our waste. There's too many of us and we're recklessly living far beyond our means. We don't seem to be able to stop ourselves, but we will stop, probably a lot sooner than most people can imagine.

6. So rather than answering the questions you gave the equivalent of "the sky is falling".

Perhaps we should sacrifice some babies and virgins to Baal to prevent the end of the world?

8. "There's too many of us"

You have complete control over helping to solve that problem.

Ask Warthog to ask the trees if they think carbon is pollution.

9. Says who? You?

"The heat is new. The oceans are brimming with it and things are starting to die. Seabird populations are crashing all around the globe. Fish runs are in trouble. Fish are dying for lack of thiamine."

11. This hysteria is nothing new



BTW looks pretty good in the Arctic.

5. I'd like to know

How much Antarctic sea ice SHOULD there be?

Maybe we have too much?

7. Perhaps the ideal global average termperature is +4C over current temps?

How do we know this isn't nature's way of correcting things and weeding out inferior species? You know evolution and all that.
