The planet is warming very rapidly, is this so much of a problem? Yes, it is. The very rapid warming is already changing the geography of Earth – with its geophysical, biological, economic and social dimensions, destabilizing climate systems on which millions of people depend from. Moreover, frequency and severity of hydrometeorological extremes are increasing, sea-level is rising, oceans are acidifying. Warming is more pronounced on land, and much more pronounced in the Arctic. Global warming has to be halted at the lowest possible level, and, for this, emissions have to go to zero as soon as possible.
Decarbonisation is not an option, it is an obligation.
