climate catastrophe has already begun to reshape human civilisation.

Annual emissions of heat-trapping carbon dioxide (CO2) are three times higher today than in the 1990s. Even if the impossible could be done -- cease all CO2 emissions today -- the average global temperature will continue to increase from the present 0.8 degrees C above normal to 1.6 - 1.8C, data shows. And that new global average temperature would remain higher than normal for the next 500 years because of the time it will take for the warming oceans to cool.
