As projected here www.nature.com/articles/s41... we are steadily moving toward a situation where are major town or city runs out of water
There are early signs of this everywhere, right now Iran seems to be a hotspot at ~1.5ºC of heating
We are *utterly* unprepared for what comes at 1.6, 1.7 & 2ºC

Climate: "We still have the ability to minimise overshoot. The best science can offer today, is a future where peak warming reaches 1.7°C before returning to within 1.5°C in 75 years. This requires immediate action at global scale, on multiple fronts" theconversation.com/the-world-lo...

The world bet on collective but voluntary action to keep global warming at a safe level.

I wonder if afghani women were allowed to answer without a male chaperone. 1.4 seems quite high for women who are not able to go to school, laugh, sing, work, have any kind of life or fun, and who can’t even go to a doctor if they are sick or injured as their are no female doctors. #womensrights
Afghans report the lowest life satisfaction in the world—
Measuring happiness is difficult, but one way to understand how satisfied people are with their lives is to simply ask them.
