Is it still possible to limit global warming to 1.5C?
A key aim of the climate negotiations at COP26 was the notion of keeping 1.5°C alive. While the emission reductions promised at Glasgow fell shy of that figure, countries were asked to return at COP27 with improved pledges to cut further.
What you will learn:
- The window for limiting global warming to 1.5°C is rapidly closing.
- The existing carbon budget – the amount of CO2 that can be emitted while still giving the world a 50% chance to contain global warming within 1.5°C compared with preindustrial levels – is only 500GtCO2.
- Equally concerning are committed carbon emissions, which suggest that projected emissions from electricity-generating infrastructure already in place exceed the remaining carbon budget.
