Climate - past, present and future

The world is now warming faster than at any point in recorded history. Kirsty Wark talks to an historian, scientist and novelist about how to convey the story and impact of climate change.

Floods, droughts, volcanic eruptions, hurricanes and solar activity have all shaped the natural history of our world from its formation. In The Earth Transformed the historian Peter Frankopan looks back at how the climate has constantly changed our world, but also at the impact of extreme climatic events on ancient human civilisations – often violent and epic in scale, from regime change to demographic decline. However, since the Industrial Revolution the balance has shifted and anthropogenic impacts on the climate can be seen more clearly. Peter Frankopan tells Kirsty Wark that learning lessons from the past has never been more important in tackling a precarious future.

Professor Dame Jane Francis is Director of the British Antarctic Survey. As a geologist by training, she studies fossils to understand the change from greenhouse to icehouse climates in the polar regions over the past 100 million years. Her research enables others to map the huge changes now happening in the Antarctic and the range of possible scenarios for the future.

“As I grew up, crisis slid from distant threat to imminent probability, and we tuned it out like static, we adjusted to each emergent normality, and did what we had always done. . . .” One of the narrators of Jessie Greengrass’s novel The High House realises too late the disastrous impact of climate change. In what has become known as the literary genre clifi – climate fiction – Greengrass reveals the physical and emotional challenges the survivors face.
