Equatorial Asia, which includes Indonesia, Malaysia, Papua New Guinea, and surrounding areas, experienced devastating biomass burning in 2015 due to the severe drought condition induced by the extreme El Niño and a positive anomaly of the Indian Ocean dipole.

Urea is a critical element found in everything from fertilizers to skin care products. Large-scale production of urea, which is naturally a product of human urine, is a massive undertaking, making up about 2% of global energy use and emissions today.

The researchers’ simulations showed that wetlands that grow in estuaries, such as salt marshes, can reduce water levels by up to 2 metres and provide protection far inland up estuary channels.

When a hurricane threatens to make landfall, forecasters offer a barrage of informational tools to communicate the risk of it coming through coastal and inland communities, so residents can prepare for its impact. 

Sea-level rise threatens to produce more frequent and severe flooding in coastal regions and is expected to cause trillions of dollars in damages globally if no action is taken to mitigate the issue.
