The Paris Climate Agreement was reached in 2015 - a landmark deal to limit our planet's global heating to well below 2°C and "pursue efforts" to limit warming to 1.5°C. But now, 11 years later, it's confirmed that this was a lie. Not a single country in the world has pursued efforts that would keep heating to this relatively safe level. And a United Nations report has now confirmed that passing 1.5 of global warming is now inevitable and imminent.
