Tamsin Edwards on the uncertainty in climate science

Description

Certainty is comforting. Certainty is quick. But science is uncertain. And this is particularly true for people who are trying to understand climate change.

Climate scientist, Tamsin Edwards tackles this uncertainty head on. She quantifies the uncertainty inherent in all climate change predictions to try and understand which of many possible storylines about the future of our planet are most likely to come true. How likely is it that the ice cliffs in Antarctica will collapse into the sea causing a terrifying amount of sea level rise? Even the best supercomputers in the world aren’t fast enough to do all the calculations we need to understand what might be going on, so Tamsin uses statistical tools to fill in the gaps.

She joined the International Panel on Climate Change (IPCC) in 2018 and is currently working on the 6th Assessment Report which will inform the 2021 United Nations Climate Change Conference, COP26. She tells Jim Al-Khalili about her life and work and why she wishes more people would have the humility (and confidence) to consider the possibility that they might be wrong.

Who guards the guards? How confident are you in your confidence report? Again, it seems Ms Roberts is whistling while the planet is lierally burning.

Tansin Roberts is unable to see the forest for the trees. She needs to read the news about the enormous fires, droughts and floods to see what has happened in a very short period of time to stop fiddling with the minutiae of her models and tweaking parameters to make a better prediction of the future which is aleady here. All this does is shield the predatory and rapacious fossil fuel industry.
