How to improve a climate model: a 24-year journey from observing melt ponds to their inclusion in climate simulations

Posted on 30 May, 2023 by danaallen

By: David Schroeder Melt ponds are puddles of water that form on top of sea ice when the snow and ice melts (see Figure). Not all the water drains immediately into the ocean, but it can stay and accumulate on … Continue reading →

Flying Through Storms To Understand Their Interaction with Sea Ice: The Arctic Summer-time Cyclones Project and Field Campaign

Posted on 1 May, 2023 by danaallen

By: Ambrogio Volonté Arctic cyclones are the leading type of severe weather system affecting the Arctic Ocean and surrounding land in the summer. They can have serious impacts on sea-ice movement, sometimes resulting in ‘Very Rapid Ice Loss Events’, which … Continue reading →

Oceanic Influences On Arctic And Antarctic Sea Ice

Posted on 14 November, 2022 by danaallen

By: Jake Aylmer The futures of Arctic and Antarctic sea ice are difficult to pin down in part due to climate model uncertainty. Recent work reveals different ocean behaviours that have a critical impact on sea ice, highlighting a potential … Continue reading →

The Devil Is In The Details, Even Below Zero

Posted on 7 November, 2022 by danaallen

By: Ivo Pasmans  An anniversary is coming up in the family and I had decided to create a digital photo collage. In the process I was scanning a youth photo and noticed that the scan looked a lot less refined … Continue reading →

Antarctic Sea Ice: The Global Climate Driver Of The South

Posted on 19 April, 2022 by danaallen

By: Holly Ayres In the Northern Hemisphere, our closest region of sea ice (not to be confused with land ice) is the Arctic, a vast region of frozen ocean at the North Pole. Antarctica, a huge mountainous land mass at … Continue reading →

Why should we care about sea ice floes?

Posted on 14 February, 2022 by danaallen

By: Adam Bateson One of the most frequently used visual devices to illustrate climate change is that of a polar bear on sea ice surrounded by open ocean (Fig. 1). Polar bears are today identified as a vulnerable species, with sea ice decline the … Continue reading →

The Future of Arctic Sea Ice

Posted on 12 July, 2021 by danaallen

By: Rebecca Frew It is well documented in scientific studies and the news (recent example here) that the summer extent of Arctic sea ice has been declining rapidly in response to global warming. As the summer sea ice shrinks and … Continue reading →

Cold Winter Weather: Despite or Because of Global Warming?

Posted on 24 May, 2021 by danaallen

By: Marlene Kretschmer This year’s winter was cold. There was heavy snowfall across the UK, Europe and parts of the United States including Texas. This severe weather came with significant societal and economic impacts. Every time cold extremes like this … Continue reading →

Are Eurasian winter cooling and Arctic Sea ice loss dynamically connected?

Posted on 14 September, 2020 by danaallen

By: Rohit Gosh The observed sea ice concentration (SIC) in the Arctic has been declining in recent decades. Temperatures have been rising all over the planet, but warming has been much faster over the Arctic, a phenomenon known as Arctic … Continue reading →
