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 →

Two Flavours of Ocean Temperature Change and the Implication for Reconstructing the History of Ocean Warming

Posted on 13 March, 2023 by danaallen

Introducing Excess and Redistributed Temperatures.  By: Quran Wu Monitoring and understanding ocean heat content change is an essential task of climate science because the ocean stores over 90% of extra heat that is trapped in the Earth system. Ocean warming … Continue reading →

How On Earth Do We Measure Photosynthesis?

Posted on 30 January, 2023 by danaallen

By: Natalie Douglas Photosynthesis is a biological process that removes carbon (in the form of carbon dioxide) from the atmosphere and is therefore a key process in determining the amount of climate change. So, how do we measure it so … 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 →

Has The Atlantic Ocean Circulation Been In Long-term Decline?

Posted on 2 May, 2022 by danaallen

By: Jon Robson A number of recent high-profile studies have strongly suggested that an important part of the North Atlantic Ocean circulation – the AMOC – has declined and that it is edging closer to a tipping point. Such a … Continue reading →
