Keynote speech at gridXdays – the conference on energy, sustainability and technology presented by gridX – from climate scientist and communicator, Stefan Rahmstorf. At the current rate we will pass 1.5 °C warming before 2040, but with decisive action we can still prevent this.
These results indicate that climate tipping is an imminent risk in the Earth System. Even the safe operating space of 1.5 or 2.0 degrees above present generally assumed by the IPCC might not be all that safe. According to the precautionary principle, we must consider abrupt and irreversible changes to the climate system as a real risk – at least until we understand these phenomena better.
