Global warming may affect the central Pacific El Niño, increasing its occurrence and leading to severe droughts in India.

River deltas across the world are sinking, leaving millions of people exposed to the risk of severe flooding.

Differentiating between two types of El Niño could make it easier to forecast bad hurricane seasons early, say researchers.

An early warning system for natural disasters using mobile phone messaging is being trialled in Bangladesh.

Mangroves cut coastal deaths during cyclones — but their effectiveness during tsunamis is inconclusive, says a new study.

NASA has developed an improved cyclone prediction method that could plug data gaps and increase warning times in vulnerable regions.

Coastal forests such as mangroves cannot protect against a tsunami on their own, and other factors should be considered, say researchers.

Researchers have mapped climate change hotspots around the globe, focusing on specific hazards including floods, cyclones and droughts.

Adverse wind conditions due to global warming will reduce the frequency of tropical cyclones, but may form stronger ones, researchers warn.

Heavy rainfall associated with a warming climate is occurring at a higher rate than current climate models predict, scientists have found.
