Once a tipping point is reached, the world's largest ecosystems could collapse at accelerated speed—the Amazon could take 49 years and the Caribbean coral reef just 15 years, scientists have warned.say that"regime shifts" tend to have a disproportionate effect on larger ecosystems. This means that though they tend to shift more slowly than smaller ecosystems, they do so disproportionately faster.
Ultimately the study shows that, once triggered, these shifts take place over"human" timescales of years and decades rather than"generational" timescales of centuries and millennia.
The good news is that these changes are not irreversible—though they may be very hard to reverse, said Wilcock. "This is what we need to do. We need to better protect our ecosystems and use resources more sustainably to prevent them collapsing. We also need to monitor our ecosystems closely and if they do show signs of collapse, we need to act fast!"
You need to be more specific in your headline.
I'll be RIP by then.
