Global warming appears to be front of mind for people worldwide.
Plate tectonics and mantle plumes set the lifespan of volcanic islands like Hawaii and the Galapagos.

Viral 'photo' is composite image, but other map shows true and growing size of devastation

Third on the Big Think 2019 countdown reveals this is what the world will be like if we do not act on climate change.
- The third most popular video of 2019 presents a frightening truth: The best-case scenario of climate change is that world gets just 2°C hotter, which scientists call the "threshold of catastrophe".
- Why is that the good news? Because if humans don't change course now, the planet is on a trajectory to reach 4°C at the end of this century, which would bring $600 trillion in global climate damages, double the warfare, and a refugee crisis 100x worse than the Syrian exodus.
- David Wallace-Wells explains what would happen at an 8°C and even 13°C increase. These predictions are horrifying, but should not scare us into complacency. "It should make us focus on them more intently," he says.

- Venice's mayor said the unusually strong flooding was caused by climate change, estimating the damage to be in the hundreds of millions of Euros.
- Venice's MOSE engineering project aims to protect Venice from rising seas, but some say it won't help the city stay above water.
