Tipping positive change to avoid climate tipping points
Wednesday 7th February 2024.
At 19.30
Meeting opens 10 minutes before.
Zoom link available to members
Prof. Tim Lenton, Exeter University.
Tipping points in climate science normally refer to small changes in the Earth system that unleash much broader, typically damaging impacts that accelerate climate change. Well-known examples are rising sea levels due to disintegration of the Greenland and West Antarctic ice sheets, or the release of methane from the thawing permafrost. They help to underline the urgency of climate action. Today most people understand we must reduce emissions – and very quickly.
This evening Tim will summarise recent evidence regarding climate tipping points, which supports declarations that we are in a ‘climate emergency’. Then he will turn to identifying positive social tipping points that will need to be triggered to have any hope of limiting global warming to well below 2C.
Tim Lenton is Chair in Climate Change and Earth System Science at Exeter University. His 25 years of research includes developing models to understand the Earth’s behaviour. He co-authored the “Planetary Boundaries” framework and is renowned for his work identifying climate tipping points. He won the European Geosciences Union Outstanding Young Scientist Award in
2006 and subsequently many other prestigious awards. He is in the top 100 Reuters “Hot List” of the worlds top climate scientists so is good at communicating his extensive knowledge.

Outcrops to Paintbox, mineral pigments in artists paints.
Soft, coloured minerals which leave a strong streak have been employed as pigments for the last 500 thousand years. This talk will introduce some of the main minerals used as pigments, their chemistry and properties and discuss how they have been used in paintings throughout art history.

The Lake District is rich in natural resources, particularly minerals, which have been exploited over many years.
These include primary or rock-forming minerals which crystallise directly from molten magma and secondary minerals, formed by hydrothermal, igneous and metamorphic processes.
This workshop will include a visual presentation about how minerals are formed followed by practical exercises to identify mineral samples from their different physical properties. There will also be a display of rocks and mineral specimens to browse and a polarising microscope to view rock thin sections.
Bring your own hand lens and grain-size card, if you have them, but spares will be available.
