Climate tipping points in Amazon, Tibet 'linked'

Climate extremes in the Amazon rainforest are directly affecting those in the Tibetan Plateau, scientists said Thursday, warning that the Himalayan region crucial for the water security of millions was close to a potentially disastrous "tipping point".
Planet-heating pollution from human activities is raising global temperatures and scientists have said this is pushing crucial ecosystems and whole regions towards often irreversible changes.
Vulnerable areas include melting polar ice sheets that could cause metres of sea-level rise, as well as the Amazon basin, where tropical forests are at risk of turning into savannah.
But can one tipping point have a domino effect on another region? Recent research suggests this is already happening.
