This week, two experts explain how melting ice in the far north is bringing more light to the Arctic Ocean and what this means for the species that live there. And we hear from a team of archaeologists on their new research in Tanzania's Olduvai Gorge that found evidence of just how adaptable early humans were to the changing environment.
Every summer, the sea ice in the Arctic melts -– but it's melting more and more each year. This dramatic loss is because the Arctic is warming two to three times faster than the rest of the planet. Different scientists are studying what climate change means for the various species that live in the Arctic Ocean. One of the things they’re looking at is light: as the sea ice shrinks, that means more light can get down to the depths, but also more ships can venture into the far north, bringing with them more artificial light.
We speak to two researchers who study what this increase in light means for the species that live in the Arctic: Karen Filbee-Dexter, Research Fellow in the School of Biological Sciences at the University of Western Australia and Jørgen Berge, Vice Dean for Research, Arctic and Marine Biology at the University of Tromsø in Norway.
In our second story, we head to the warmer climes of the Olduvai Gorge in Tanzania, known as the birthplace of humanity. We speak to a team of researchers, Julio Mercader, Professor of Anthropology and Archaeology at the University of Calgary in Canada, and Pastory Bushozi, Director of Humanities Research Centre and Makarius Peter Itambu, Lecturer in the College of Humanities, both at the University of Dar es Salaam in Tanzania, about their recent discoveries in the gorge. They found new evidence of just how adaptable early humans were to the changing environment around them around 2 million years ago.
And Laura Hood, politics editor at The Conversation in London, recommends a couple of recent stories by academics in the UK.
