“Clouds and climate” with Prof Tapio Schneider @ Oxford Martin School
Sep 5 @ 4:00 pm – 5:15 pm

Crocodiles once roamed the Arctic, during the Eocene about 50 million years ago. Polar regions were lush and warm. Greenhouse gas concentrations were higher than today, but at most about 4 times higher – not enough, according to current climate models, to have warmed the Arctic sufficiently. Something appears to be missing in current models to account for the warmth of the past.

The likely culprits are clouds, especially the low clouds that cover vast areas of tropical oceans. These clouds cool Earth by reflecting sunlight back to space. It is possible that the cloud cooling may have been absent or strongly diminished in past greenhouse climates, raising questions about our climate future. To predict our climate future more accurately, breakthroughs in the modeling of clouds and in the accuracy of climate predictions are needed. They are now within reach, thanks to advances in computing and Earth observations from space and our ability to fuse models with massive amounts of data.

“The technology trap – capital, labour and power in the age of automation” with Carl Benedikt Frey @ Oxford Martin School
Oct 14 @ 5:00 pm – 6:00 pm

In this book talk the Author, Carl Benedikt Frey, will discuss how the Industrial Revolution was a defining moment in history, but how few grasped its enormous consequences at the time. Now that we are in the midst of another technological revolution how can the lessons of the past can help us to more effectively face the present?

This talk will be followed by a book sale, signing and drinks reception. All welcome.
