Coffee Morning – Climate Change – Tipping Points & When will they happen?
A climate tipping point is a threshold in the Earth’s climate system that, when crossed, can lead to irreversible and potentially catastrophic changes. These changes can be triggered by relatively small increases in global temperatures and could have significant, long-lasting consequences for ecosystems and human societies

The Royal Meteorological Society has produced an excellent report from which the chart above is taken. You can read it here. It’s called Tipping Points- typical thresholds for climate change.
We will have a talk today from Sahil Shah

Sahil – our speaker today


A footnote on Tuesday’s talk from this week’s issue of The Economist:
“For some, talk of tipping points is a harmful distraction. In 2024 an international group of well-known scientists published an article in Nature Climate Change arguing that a focus on tipping points diverted attention from the more general need for climate mitigation and adaptation, around which the science is much more certain.
“Others worry about fostering a sense of fatalism, by framing some catastrophic changes as unavoidable.
“Regardless, the concept is slowly but steadily gaining ground.
“In July a big conference on tipping points in Exeter attracted actuaries, insurers and pension funds as well as scientists and activists.”
