Earth may have already hit climate change 'tipping point' (Global)
Updated: Dec 3, 2019
We may have already pushed our planet beyond several tipping points and towards a scenario where the Earth begins “self amplifying” global warming in a series of unstoppable destructive feedback loops, scientists calling for an international emergency response have warned.
More than half of the climate tipping points identified a decade ago are now “active”, with immediate threats including the loss of the Amazon rainforest and the great ice sheets of Antarctica and Greenland, all of which are currently undergoing measurable and unprecedented changes much earlier than expected.
This amounts to an “existential threat to civilisation”, which requires an “emergency response”.
