Arctic Sea-Ice Extent Now Greater Than at Nearly Any Time in the Last 10,000 Years

Also, today’s sea surface temperatures are at least 4°C colder than they were just a few thousand years ago, when the Arctic was sea-ice free for all but a couple of months a year.
Three new studies expose the lie that today’s temperatures are the warmest on record.

Study location

For years scientists have been using biomarker evidence to reconstruct Arctic sea ice history. According to three new studies, modern (20th-21st century) Arctic sea ice is now at its greatest extent since the Holocene began.

Arctic was “nearly ice free throughout the year”

Scientists (Wu et al., 2020) have determined that from about 14,000 to 8,000 years ago, when CO2 lingered near 250 ppm, the Beaufort Sea (Arctic) was “nearly ice free throughout the year.” Not only was it nearly ice free, it was ~4°C warmer than today in winter.

With CO2 at ~400 ppm, this region is 70-100% ice-covered for all but 1-2 summer months in the modern era.

Glaciers had retreated many km (miles) from their modern positions

Another new study (Allaart et al., 2020) concludes that from around 10,000 to 5,000 years ago, Arctic Svalbard (Wijdefjorden) glaciers had retreated many km further back than their modern positions. And the smaller ice caps had “disappeared” from the region.

Today’s sea surface temperatures are at least 4°C colder than just a few thousand years ago

A third study involving a site northeast of Svalbard (Brice et al., 2020) reveals that today’s sea surface temperatures of “<0°C” are at least 4°C colder than they were just a few thousand years ago, when the Arctic was sea-ice free for all but “a couple of months” every year.

  1. Ignorant arts graduates shilling for a living in the MSM may be going a rather deep shade of purple, if shame is still an emotion they are capable of experiencing….

  2. CO2 at 250ppm and the Arctic ice free?
    How about that! CO2 is not the blame after all.
    Tell us again, Gore, how CO2 is melting the poles!

  3. Temperatures peaked in the early Holocene, sea levels were the highest, polar ice the lowest. As the Holocene progressed temperatures dropped off, sea levels went down, ice increased. That trend will continue as the Holocene reaches glacial inception.

    The trace gas CO2 is of dubious effect, and will not slow or affect the ice age progression IMO based on previous ice ages with high CO2 above 3,000 ppm.

    After the dinosaur era, the poles were still quite warm, high latitudes had redwoods when today it is snow and rocks.

    I bring these science studies up to illustrate that the world is not in some runaway warming. The news media is a theater of the absurd, making the public believe things like global warming is a threat when we are clearly still in the depths of an ice age that started 2. 6 million years ago an may last many more millions of years.

    The National Oceanic and Atmospheric Administration (NOAA) has reported that there is a 75 per cent chance 2020 will be the warmest year on Earth since record-keeping began in 1880. Global temperatures are expected to be warmer than those in 2016, which was declared the warmest year on record at the time… Covid-19 to the rescue… COULD COVID-19 CHANGE THIS?
    The widespread lockdowns that have been implemented to slow the spread of COVID-19 have slashed greenhouse gas emissions in some of the most polluted parts of the world.
