Arctic sea ice extent should be nearing or at minimum in about two weeks, no, Mr.Neil? Both extent and area in the Arctic look good atm. Best in many years? |

Sea Ice in 2020 showed two rapid downturns in mid July and mid August.
So far this year, this does not seem to have occurred.
Can anyone explain why?

NSIDC daily area minimum will most likely be 8.23.2021, with a value of 3.389173 million square kilometers. The 8.25 value is 3.501343 millions of square kilometers. We are now 112,170 kilometers above the minimum value. This would be the earliest daily area minimum in the satellite record. Bear witness to history.  Meanwhile, Southern hemisphere sea ice area is approaching the all time high.  The NSIDC sea ice extent value for 8.25, is higher than the 8.23 value. Many point to the 2007 melting season as the year the arctic changed. If one were to hypothesize a sea ice recovery to pre 2007 levels, 2021 could be looked at in the same light. 2020 was the second lowest sea ice extent northern hemisphere sea ice minimum on record. If we end 2021 in 15th place, this would be the largest place year to year difference on record. |

Can we make a "hockey stick" graph from the recent ice data?

Chart still looks good for arctic ice extent. But it can go south fast though. Look at 2012. I remember terrible heat in the central US in 2013 and 2014. Not that they are meaningfully related .

That was probably minimum extent on Sept 1st?  |

Took them long enough. Most active members on this board have recognized this for over a decade. |

"Scientists Now Blame Geothermal Heat For Melting Antarctic Glaciers"
Took them long enough. Most active members on this board have recognized this for over a decade. "There are none so blind as those who will not see."  I have also wondered for some time whether the persistence of heat in the northern part of the NAD has something to do with geothermal activity. In general, we have seen volcanism increase in the on-going solar downturn. The North Atlantic "cold spot" that accumulated some years back has been blamed by some on ice melting. Currently warming seems to be underway in the same areas. Is there a geothermal source? |
