Mangroves help fight climate change but they’re at serious risk from its effects. That’s one of the findings from a study of a massive mangrove dieback that occurred in late 2015.
Local fishermen reported mangroves were dying along hundreds of kilometres along the Gulf of Carpentaria coastline, an area known for its barramundi fishing and high value commercial fisheries.
This caught the attention of Dr Damien Maher of Southern Cross University, who is interested in the chemistry of mangroves—how they store carbon in their soils, remove planet-warming nitrous oxides from the atmosphere, and neutralise ocean acidification by releasing alkaline chemicals into nearby waters.

In lands ‘of droughts and flooding rains,’ predicting the weather means saving both lives and livelihoods.
The work of Indonesian and Australian scientists, which began with a visit to Jakarta in 1981 by climate scientist Professor Neville Nicholls, has given the countries the ability to forecast rain in the dry season, and during the lead up to the wet season. This means the fires, haze, and food shortages that often go hand in hand with droughts can be predicted—and planned for.

Thermometer-based climate records started in 1850, so scientists have gone “back to nature” for sources of long-term climatic information to help them better understand climate change and rising sea levels.
