If we stopped producing greenhouse gases now, how long would it take before the effects of climate change left us?

That’s something that scientists are studying in quite a lot of detail now, so if we did, for example, meet the Paris agreement target of 1.5 degrees of warming by the year 2050. So in about 30 years time, there would still be a little bit of warming that we’re committed to and that gap or that lag time as we could refer to it could be a few decades. So what we will see is that warming would continue over the next few decades and then gradually it would start to come down. So we think if we took action and we limited warming to 1.5 degrees in 2050 over the next 30 to 50 years, temperatures should then lower and become more stable by around about 2100, so in about 80 years time – Professor Chris Stokes.
