«This perspective article focuses on intervals in time in the fossil record when atmospheric CO2 concentrations increased up to 1200 ppmv, temperatures in mid - to high - latitudes increased by greater than 4 °C within 60 years, and sea levels rose by up to 3 m higher than present.

Combined climate / ice sheet model estimates in which the Greenland surface temperature was as high during the Eemian as indicated by the NEEM ice core record suggest that loss of less than about 1 m sea level equivalent is very unlikely (e.g. Robinson et al. (2011).

Whether we look at the steady increase in global temperature; the buildup of greenhouse gases in the atmosphere to the highest level in a half - million years; the march of warmest - ever years (9 of the10 hottest on record have occurred since 2000); the dramatic shrinking of mountain glaciers and Arctic sea ice; the accelerating rise in sea level; or the acidification of our oceans; the tale told by the evidence is consistent and it is compelling.

Greenhouse gas concentrations and global sea levels both set new record highs this year.

I understand that melting sea ice does not contribute to sea level rise, but the fact that Antarctic sea ice is at record high levels seems inconsistent with proposed rapid melting of Antarctic ice sheets.

What are your feelings on the Antarctic sea ice anamoly and the record high level of sea ice there this past year.

Hi iceman, Sorry for the tardy reply, that pesky real life thing again...:) The reason there is so little excitement about the record high sea ice extent in the antarctic (aside from it having no appealing potential victims, like polar bears) versus the record low arctic sea ice is probably because the southern record is only a matter of 2 % anamoly, whereas in the north we are now looking at levels over 40 % below average.

We continue (AFAIK) to have some high sea surface temps; the troposphere continues at record - or near - record levels; and we may or may not have reached the seasonal maximum yet.

For example, when Hurricane Sandy pushed a record - high storm surge into New York Harbor, the surge rode on top of seas that were already about a foot higher at that location than they were in 1900, due to both climate change - related sea level rise and land subsidence.

Based on a small number (~ 25) of high - quality tide gauge records from stable land regions, the rate of sea level rise has been estimated as 1.8 mm yr — 1 for the past 70 years (Douglas, 2001; Peltier, 2001), and Miller and Douglas (2004) find a range of 1.5 to 2.0 mm yr — 1 for the 20th century from 9 stable tide gauge sites.

In 2017, sea ice levels during the spring were higher than usual in the Labrador Sea (home to Davis Strait polar bears) and as a consequence, communities in coastal Labrador and Newfoundland saw record - breaking numbers of bear sightings, including a scary encounter that resulted in a bear being shsea ice levels during the spring were higher than usual in the Labrador Sea (home to Davis Strait polar bears) and as a consequence, communities in coastal Labrador and Newfoundland saw record - breaking numbers of bear sightings, including a scary encounter that resulted in a bear being shSea (home to Davis Strait polar bears) and as a consequence, communities in coastal Labrador and Newfoundland saw record - breaking numbers of bear sightings, including a scary encounter that resulted in a bear being shot.
