20180521 | Five scientists, working in different parts of the world, bear witness to some of the dramatic changes to our planet that have occurred in their lifetimes, as the global climate warms. 1. Marine biologist and underwater diver, Professor Callum Roberts of the University of York, has seen coral reefs that were once multi-coloured and teeming with life reduced to grey, lifeless underwater landscapes with devastating consequences for marine bio-diversity. Just 0.1% of the ocean life is coral reefs but they support more than a quarter of all the species that live in the sea. Marine biologist Callum Roberts on how corals showed him the impact of climate change. Five scientists describe how their eyes were opened to global climate change. |
20180522 | Five scientists, working in different parts of the world, bear witness to some of the dramatic changes to our planet that have occurred in their lifetimes, as the global climate warms. 2. Professor Sir John Lawton is an ecologist and Vice President of the RSPB. He has been bird-watching in the UK since he was a boy. He remembers bird populations that have now collapsed and has seen Mediterranean species that were once rare in the UK become commonplace: multiple canaries in the global climate coal-mine, he says. Environmental scientist John Lawton describes the impact of global climate change on birds Five scientists describe how their eyes were opened to global climate change. |
20180523 | Five scientists, working in different parts of the world, bear witness to some of the dramatic changes to our planet that have occurred in their lifetimes, as the global climate warms. They share their hopes and fears and report on some ingenious local solutions to rapidly changing conditions. 3. 3 million square kilometres of ice has been lost in the Arctic since 1979. Geographer, Professor Mary Edwards lived in Alaska for many years. She has witnessed a cruise ship navigating the Northwest Passage for the first time and seen villages in the Arctic disappear, as melting ice has led to a dramatic loss of landmass too. Geographer Mary Edwards on the melting of ice in the Arctic and climate change. Five scientists describe how their eyes were opened to global climate change. |
20180524 | Five scientists, working in different parts of the world, bear witness to some of the dramatic changes to our planet that have occurred in their lifetimes, as the global climate warms. 4. In May 2004, Professor Jennifer Leaning of Harvard University's FXB Center for Health and Human Rights, led a two-person human rights investigation into the reported widespread attacks and killings against agrarian villagers in Darfur, in Western Sudan. The villagers became refugees in neighbouring Chad. Jennifer Leaning explains how this trip lead her to realise that climate change has a crucial part to play in human migration. Jennifer Leaning on human migration, the environment and climate change. Five scientists describe how their eyes were opened to global climate change. |
20180525 | Five scientists, working in different parts of the world, bear witness to some of the dramatic changes to our planet that have occurred in their lifetimes, as the global climate warms. 5. Richard Dawson, Professor of Earth System Engineering at Newcastle University, was the lead author of the Infrastructure section of the UK Climate Change Risk Assessment 2017. He reflects on how he and his fellow civil engineers now view flooding from a variety of sources the main threat to our infrastructure. Richard Dawson on the UK's engineering infrastructure, flooding and climate change. Five scientists describe how their eyes were opened to global climate change. |
