Arctic ocean moorings shed light on winter sea ice loss

The eastern Arctic Ocean’s winter ice grew less than half as much as normal during the past decade, due to the growing influence of heat from the ocean’s interior, researchers have found.

10 fallacies about Arctic sea ice & polar bear survival refute misleading ‘facts’

Summer sea ice loss is finally ramping up: first year is disappearing, as it has done every year since ice came to the Arctic millions of years ago. But critical misconceptions, fallacies, and disinformation abound regarding Arctic sea ice and polar bear survival. Ahead of Arctic Sea Ice Day (15 July), here are 10 fallacies that teachers and parents especially need to know about.

Video: How simple math can help predict the melting of sea ice

Anurag Papolu, The Conversation To better predict climate change, scientists need accurate models which predict the behavior of many natural processes. One of these is the melting of arctic sea ice, which requires expensive and difficult data collection in the Arctic. Physicist Ivan Sudakov at the University of Dayton and his colleagues have developed a…

Antarctic sea-ice models improve for the next IPCC report

University of Washington The world of climate modeling is complex, requiring an enormous amount of coordination and collaboration to produce. Models feed on mountains of different inputs to run simulations of what a future world might look like, and can be so big — in some cases, lines of code in the millions — they…

Claim: Antarctic Sea Ice Growth Caused by Meltwater

Guest essay by Eric Worrall According to climate scientists, less dense meltwater on the surface of the Antarctic ocean reduced convection between the surface and ocean depths, leaving heat trapped in the depths. One small area of ocean not changed by global warming Date:May 6, 2020 … Climate and marine scientists are observing pervasive warming…
