Arctic temperatures warmest in over 10,000 years

Arctic temperatures are the warmest in more than 10,000 years, speeding the thaw of permafrost in Canada’s North, shows climate research out of the University of Alberta.

“We’ve known that the last few decades have been very warm. But we’ve found that temperatures are on the order of two degrees Celsius warmer than any time in the last 10,000 years — that was a surprise,” Duane Froese, professor in the Department of Earth and Atmospheric Science, and Canada Research Chair in Northern Environmental Change…

❝ The study found that previous record highs occurred during the early Holocene period — around 9,900 and 6,400 years ago. But even without the unique circumstances of that period, when the Earth’s axis was more strongly directed toward the sun, current Arctic temperatures have exceeded those records.

“All indications from this new study are that temperatures and the impacts of recent warming are only picking up and getting stronger,” said Froese. “We are moving into uncharted waters with respect to climate change in the North.”

Gee, I hope this doesn’t upset the Trump supporters who are dedicated to searching for “science” that backs the fantasies of their Great Leader.

    As global warming creates shipping routes that can cut across the northern tip of the planet, a new port is being built on the fringe of the Arctic circle. https://gcaptain.com/iceland-building-arctic-port/ Ships stopping at the new Icelandic port on the island’s northern tip stand to reduce their travel time considerably. “If the northeast passage between Asia and the U.S. becomes navigable all year round, the journey times between these continents will be reduced by more than two weeks,” according to Germany’s Bremenports GmbH.

    The release of methane and carbon dioxide from thawing permafrost will accelerate global warming and add up to $70 trillion to the world’s climate bill, according to the most advanced study yet of the economic consequences of a melting Arctic.

      Greenland Was on Fire This Week Amid ‘Unprecedented’ Arctic Burn https://earther.gizmodo.com/greenland-was-on-fire-this-week-amid-unprecedented-arct-1836309604 “…climate change is cranking up the heat there and around the Arctic, which is in turn creating hot, dry conditions that make fires increasingly common. That’s be borne out this summer not just on Greenland but across the northern tier of the world.
      Wildfires have roared across Alaska, consuming over 600,000 acres from July 3-10. More 10,000 lightning strikes hit the state between Wednesday and Thursday, almost surely igniting more fires for crews to battle. Siberia and northern Canada have also battled large blazes over the past few months.
      The European Union’s Copernicus program found that June was a period of “unprecedented” wildfire activity for the Arctic.
      “In June alone, these fires emitted 50 megatonnes of carbon dioxide into the atmosphere, which is equivalent to Sweden’s total annual emissions,” the agency wrote in a blog post. “This is more than was released by Arctic fires in the same month between 2010 and 2018 put together.”
      That means the fires are not only feeling the influence of climate change, they’re contributing to it by emitting more carbon into the atmosphere as trees and stores of peat go up in smoke. And that will accelerate the changes taking place.

    Gaku Kudo of Hokkaido University and Elisabeth J. Cooper of the Arctic University of Norway have demonstrated that early snowmelt results in the spring ephemeral Corydalis ambigua flowering ahead of the emergence of its pollinator, the bumblebee.
    Global warming has affected the phenology of diverse organisms, such as the timing of plant flowering and leafing, animal hibernation and migration. This is particularly so in cold ecosystems, increasing the risk of disturbing mutual relationships between living organisms. It could also affect the relationship between plants and insects that carry pollen, but few studies have been conducted and the subject remains largely unknown.
    …”Our study suggests the early arrival of spring increases the risk of disruption to the mutualism between plants and pollinators,” says Gaku Kudo. “Studying how this phenological mismatch will affect the reproduction and survival of plants and insects could give us clues to the larger question ­­­­of how global warming is affecting the overall ecosystem.” https://www.global.hokudai.ac.jp/blog/early-arrival-of-spring-disrupts-the-mutualism-between-plants-and-pollinators/
