A elevação dos mares está levando ecossistemas costeiros ao limite da resistência. Uma pesquisa internacional revela que um “ponto de inflexão” será atingido se permitirmos mais de 2°C de aquecimento

Rising seas are pushing coastal ecosystems to the limit of endurance. Now international research reveals a “tipping point” will be reached if we allow more than 2 degrees of global warming.
Millions of mangroves died off along Australia’s northern coast. The cause? El Niño - and the moon’s wobbly orbit causing extremely low tides.
Tidal marshes can build up their soil to keep pace with sea-level rises – up to a point. It turns out the point when the marsh is drowned matches the average rise when global warming exceeds 1.5°C.
One surprising potential benefit of sea-level rise is it helps coastal wetlands store more carbon.
Mangroves - one of the most important trees - are threatened by rising seas. While these forests can adapt, human development is getting in the way.
