Stop That Now! Climate change helps aggressive mangrove forests build bigger tropical islands

The oceans were supposed to be swallowing up the islands

Climate change has unleashed rampant growth in mangrove forests. The trees are capturing coral detritus in large sand drifts, and locking it into whole new ecosystems that expand 5 to 6 meters a year. It’s just remarkable — some islands have grown by several kilometers since 1928.

The Howick Group of islands is north of Cairns Australia. Three scientific expeditions mapped out them out in 1928 and in 1974, and again in 2021, and lo, they have grown, especially in the last four decades. That makes them like most of the 709 islands of the Pacific and Indian oceans that were studied a few years ago. Satellites showed that 89% of those islands had grown.

It turns out warmer more carbon rich world makes mangroves happy. Who could have seen that coming, apart from every biologist on Earth?

From the commentary in the video below:

“We’ve seen some really dramatic changes. Some of the things that we’ve seen are advancing fronts of forests. Forests that were mapped to small patches on the windward part of the reef flat are now occupying a much larger section of […]
