    Rapidly receding Arctic Canada glaciers revealing landscapes continuously ice-covered for more than 40,000 years

    Here we show that pre-Holocene radiocarbon dates on plants collected at the margins of 30 ice caps in Arctic Canada suggest those locations were continuously ice covered for > 40 kyr, but are now ice-free. We use in situ 14C inventories in rocks from nine locations to explore the possibility of brief exposure during the warm early Holocene. Modeling the evolution of in situ 14C confirms that Holocene exposure is unlikely at all but one of the sites. Viewed in the context of temperature records from Greenland ice cores, our results suggest that summer warmth of the past century exceeds now any century in ~115,000 years.

    Warmth. Around 130,000-110,000 years ago (the Eemian interglacial), the Earth's climates were generally much like those of today, though somewhat warmer and moister in many regions. The climate record derived from long ice cores taken through the Greenland ice cap suggested that the warm climate of the Eemian might have been punctuated by many sudden and fairly short-lived cold phases, but these results are now thought of as inaccurate because the lower layers of the ice sheet have become buckled and jumbled up. However, at least one major cold and dry event during the Eemian seems to be corroborated by the terrestrial pollen record from Europe and China

    That’s the problem, right there. All the tropical convective forcing is well west of the dateline, around Australia. There has been an explosion of tropical storm activity around/north of Australia recently. All that convective, latent heat release into the upper troposphere helps to really strengthen and push the west Pacific High poleward. A strong poleward west Pacific High promotes the pattern the long range ensembles are showing. Look at the SSTs out that way, they are on fire, helping the positive feedback process and latent heat release 

    it's summertime in australia so of course the sst are going to be very warm....

    NYC has only had a single white Christmas in my lifetime (90’s baby), it simply isn’t a reasonable expectation, in my humble opinion. Snow before the New Year should be viewed as an appetizer, January-March is the meal. 

    well in nyc since 1990 their have been 6 times of 6 or more inch snowfall in december...long island use to be not as snowy as the city back then but the last 10 years it is more snowy...now...checking long island in general their have been more than just 1 big snows in december since 2000

    that is not accurate at all what about the  2010 day after christmas blizzard or the dec 1947 blizzard.. there has been plenty of big snows in nyc in the month of december....

    I haven’t seen Yakutsk ever at -80 but I’m sure they’ve hit. Yakutsk did hit 101 in 2011 all time high. But it doesn’t hit every year. It does seem to have 90’s every year. I would love to visit that city during the summer though for some reason. The two small cities you just mentioned hold for two of the coldest temperatures in the northern hemisphere 

    coldest:

    Oymyakon reached −67.7 °C (−89.9 °F)

     

    2nd coldest:

    Verkhoyansk −67.6 °C (−89.7 °F)

     

    by the way para gfs was suppressed for next week.

    yakutsk does not get as cold as it use to be due to climate change...
