Opinion: Vacations as we know it are over
CNNEditor’s Note: Bill McGuire is Professor Emeritus of Geophysical & Climate Hazards at University College London and author of “Hothouse Earth: An Inhabitant’s Guide.” The views expressed in this commentary are his own. On the contrary, the extreme weather conditions across southern Europe this summer are a wake-up call — a reminder that not even our vacations are insulated from the growing consequences of global heating. A 2 degrees Celsius rise, which we are currently on target to far exceed by the end of the century, would see the average number of heatwave days increase six-fold across southern Europe — so that 1 in 100-year heatwaves would happen every other year. A new report finds that heat waves in the US and Europe this year would have been "virtually impossible" without climate change. For many of us, jetting off every year on a foreign break has almost become instinctive — just something we do without really thinking about it.
