Professor Anna Hogg joins us on today’s programme for some polar explorations, we speak to one team recalculating arctic warming estimates and another who are storm chasing in Svalbard. Antii Lipponen from the Finnish Meterological Institute talks us through how quickly the arctic is really warming and Professor John Methven and PhD student Hannah Croad from the University of Reading send greetings from Svalbard where they’re chasing arctic storms.

Also, new evidence for a possible biomarker of ME/Chronic Fatigue Syndrome - a condition associated with debilitating tiredness and brain fog similar to Long Covid. The microclots, described by Professor Doug Kell at the University of Liverpool and Professor Resia Pretorius of University of Stellenbosch, suggest a possible inflammatory cardiovascular element to the disease which might one day forge a path towards new treatments.

And how can trees help us in a heatwave? Vic joined Dominik Spracklen from the University of Leeds on a stroll around a Cumbrian forest to explore the cooling potential of forests.
