A group of researchers, who published a commentary in the journal Nature, said there is growing evidence indicates that the irreversible changes to the Earth's environmental systems is already underway, and that we are now in a "planetary emergency".
In addition to points-of-no-return in Amazon rainforest cover and ice melt in Greenland and the Antarctic, other critical tipping (or rather, tipped) points the group identifies include: Arctic sea ice melt, boreal forest cover, permafrost cover, warm-water coral reef cover, and adjustment in the integrated cold-warm water exchange via currents in the Atlantic Ocean - more formally known as Atlantic meridional overturning circulation.
The Earth is heading towards an "international tipping level" if the climate crisis continues on its present path, scientists have warned, as they referred to as for urgent action to keep away from "an existential risk to civilization". Plod beyond that and we're at chance of unleashing self-bolstered warming - that is what Earth draw scientists grief most.
It's not just that the steady, measurable burden of human activity on the Earth's environment has intensified, but that scientific advances have revealed the planet is already "self-amplif [ying]" these manmade effects even at the current 1.1 degrees Celsius of global warming.
The moment that the Earth system flips over from being self-cooling - which it still is - to self-warming, that is the moment when we lose control.
Monitoring and recording changes in the various climate systems can give scientists valuable data on the health of those systems and how far they are tipping to the point of no return.
They include widespread destruction of the Amazon, the reduction of Arctic sea ice, large-scale coral die-off, melting of the Greenland and West Antarctic ice, thawing of permafrost, destabilizing the boreal forest - which contains a large number of trees that grow in the freezing northern climates - and a slowdown of ocean circulation.
When this sector collapses, it may destabilise the remainder of the West Antarctic icesheet like toppling dominoes, resulting in about three metres of sea-level rise on a timescale of centuries to millennia.
Q. Does that mean we desire to shift our focus to preparing for the inevitable impacts that can notice?
LENTON: We will have to adapt to some changes that may now be unavoidable. Models counsel that the Greenland icesheet is doubtless to be doomed at 1.5C of warming, which can perhaps perhaps happen as soon as 2030.
For long-term sea degree rise, then, we needs to be trying significantly at relocation.
We've got a short-term challenge which is to try and get to net-zero greenhouse gas emissions in the next 30 years. That ought to be the focus of the most urgent attention. We want a joined-up technique - it needs to be a two-pronged strategy.
Q. You spotlight the methods by which totally different aspects of Earth's local weather system work together, and the way that will amplify the chance of dire impacts.
There's a connection, for instance, between the Arctic and Antarctica by way of the ocean circulation system within the Atlantic.
About 17 per cent of the Amazon has been lost since 1970. Estimates of where an Amazon tipping point could lie range from 40 per cent to just 20 per cent of forest-cover loss.
