Man-made emissions have been pushing up Earth’s temperature through the Greenhouse Effect, and much more warming is expected during our lifetimes if emissions aren’t reduced. But warming may not be gradual – passing a ‘tipping point’ can cause sudden change. Scientists are now worried that we’re approaching some of these tipping points, beyond which rapid and difficult-to-reverse climate changes may occur. This helps to make climate change more of a so-called “Wicked Problem” to respond to, as it makes future climate change more difficult to predict and comprehend. Join Dr. David Armstrong McKay to find out about what climate tipping points are, how might they affect us, and whether we can predict and avoid them.
