Evidence that Australia's Great Barrier Reef is experiencing its worst coral bleaching on record has renewed calls for the UN to list it as "in-danger".

The National Coral Bleaching Taskforce says 95% of reefs from Cairns to Papua New Guinea are now severely bleached.

It says only four reefs out of 520 have no evidence of bleaching.

A new report from the World Meteorological Organization (WMO) suggests global climate change is advancing at an alarming and "unprecedented" rate.

Last year's extreme weather broke a series of records, including global temperatures, exceptional rainfall, devastating droughts, unusual cyclone activity and intense heat waves. And while 2015 proved to be the warmest year worldwide, 2016 is expected to far exceed those records.

Key factors that can combine to produce a Zika virus outbreak are expected to be present in 50 US cities during peak summer months, a study has warned.

The Aedes aegypti mosquito, which is spreading the virus in much of Latin America and the Caribbean, will likely be increasingly abundant across much of the southern and eastern US as the weather warms, according to the study led by experts at the National Centre for Atmospheric Research (NCAR) in US.

Summertime weather conditions are favourable for populations of the mosquito along the East Coast as far north as New York City and across the southern tier of the country as far west as Phoenix and Los Angeles, according to computer simulations conceived and run by researchers at NCAR and the NASA Marshall Space Flight Centre.
