Hello and welcome to Ways to Change the World. I'm Christian Gary Murphy and this is the

podcast in which we talked to extraordinary people about big ideas and the events and

their lives that have helped shape them. My guest this week is an award-winning science

writer and journalist who certainly has a big idea. Her latest book is called No Mad Century

and Guy Avins' proposition is that the world is going to have to see mass migration

on a scale the likes of which we have never seen before in order to adapt to the climate

emergency. Guy thank you for joining us. No Mad Century sounds like this is inevitable.

Do you think the idea of mass migration is now unstoppable? Migration is already happening

because of the climate change that we've already made. I mean if you look at just this year

we've experienced extreme weather conditions across the planet. So huge amounts of drought

across Europe, across China. It's so severe that hydropower stations can't function in

China which is affecting economic production, food production and that of course affects

the whole world. It also makes areas unlivable. If you look at Europe we've had forest fires

burning, wildfires out of control, people have sadly lost their lives. The ONS reckons

that the heat wave we had just for one week in July raised the death toll by a fifth over

the year-on-year average for that time of year. I mean the current argument around climate

change and reducing carbon emissions is that this is avoidable, that drastic changes to

the way we live are yet preventable. What I'm saying in No Mad Century is raise your

head above the day-to-day and have a look at what we are facing. Just really look head

on what we're facing and then be pragmatic because we do have choices. Of course we do.

We can avoid extreme, more extreme temperature rise but not just through emissions reductions

anymore. We're already raising that. We had the COP26 last year where all the broadcasters
