How to understand climate modelling - and why you should care | Shannon Algar | TEDxKingsPark

Finally, a clear explanation of what a climate tipping point is! We hear about climate modelling and the predictions scientists make, but do you know how modelling is done? Shannon is here to help with a simple but powerful description of how tipping points are the key to understanding climate change. Dr. Shannon Algar is an applied mathematician using sophisticated modelling techniques to understand complex, real-world systems, like the timing of ice ages and species extinction. Shannon is a post-doctoral researcher and Forrest Prospect Fellow with the Complex Systems Group at the University of Western Australia. Her research is centred around systems modelling, covering broad areas of Complexity, Swarm Intelligence, Reservoir Computing, Topological Data Analysis and Time Series Analysis. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at www.ted.com/tedx

Great work! Congratulations!

[@diyorbekabduvoitov6625]

Great

[@nickbreen287]

If you have a model, it has to be a working model that reflects real world climate, call me when you get one.

[@RogerRocks]

They all work. Even the basic energy balance model. What doesn't work is whatever produces predictions of looming ice ages just around the corner.

[@nickbreen287]

@@RogerRocks None are producing accurate predictions. Or maybe they are but the results are not dramatic enough to publish.

[@RogerRocks]

@@nickbreen287 Oh ffs. You are impervious to evidence or logic, a cultist.

[@bru512]

I would add that the model needs to work into the recorded past and at all points into the future. Please direct me to anyone that has a model that can do that, or is attempting to do that and is publishing results

[@OmeSees]

Did you ever try one? Callendar's 1938 energy balance model is pretty accurate for the heating that has been observed in the past 80 years - and the predictions for the coming 80 that it makes are not looking good for our future.

[@FineWino]

What bunch of BS.

[@OmeSees]

must hurt that there were people in 1896 that grasped more about climate change than you .

Why lol
