Through decades of research, and now lived experience, it has become clear that the impacts of climate change will have drastic and far-reaching consequences on our planet. And while some of those consequences are predictable — like more extreme weather, sea-level rise and loss of biodiversity — the pace at which these unfold and their eventual severity hinge on what happens with key linchpins in the climate system, called tipping points. A tipping point is a threshold or point of no return in the climate system that once passed can no longer be reversed. Passing a tipping point does not necessarily mean immediate, drastic consequences, but it does mean those consequences become unavoidable, and over time the impacts may be dramatic. In a 2019 paper, Professor Timothy Lenton, a global leader on the subject, identified nine climate tipping points, from melting permafrost in the Arctic to the loss of tropical coral reefs. Here we will focus on what he deems the three most critical tipping points: the Amazon rainforest, the West Antarctic ice sheet and the Gulf Stream system.
