Most Australian capital cities have at least 80% chance of unusually warm and dry spring as climatologists watch developing system with increasing alarm

The El Niño climate phenomenon linked to record global temperatures and now locked in place in the Pacific Ocean could develop into the strongest on record, according to Australia’s Bureau of Meteorology.

Climatologists are watching the strengthening El Niño with increasing alarm, saying the forecasts from climate models in the coming months are “mind blowing” and “astounding”.

Norfolk Island’s unique corals under triple threat from disease, El Niño and now government-approved dredging

Posted on by

Exclusive: Most of the island’s corals are likely to be species that have not been formally described by science, researcher says

Scientists fear unique corals that fringe Australia’s remote Norfolk Island could disappear because of a triple threat of disease, El Niño and a federal government plan to dredge a neighbouring shipping channel.

A failure to manage sediment and pollution washing into bays from cattle farming, cleared land along with wastewater has been blamed for widespread disease and outbreaks of algae over the corals.

Exclusive A vast area of the Bellingshausen Sea should be covered by sea ice by now, with one expert calling the loss of ice ‘depressing’

Antarctica’s west coast is missing an area of winter sea ice the size of France, sparking concerns for threatened penguins other marine life and global sea levels.

One expert said the loss of ice in the Bellingshausen Sea was “depressing” and the failure of ice to form could have intensified a heatwave over the continent’s peninsular last week that saw daytime temperatures peak at 15.4C which is more than 20C above average.

‘Don’t fall!’: foil boarders describe hair-raising shark chase caught on video off California coast

Posted on by

Foil boarders were pursued by shark – likely a great white – off Santa Barbara before it lost interest and swam away

Ron Takeda and Tavis Boise were a few miles off the coast of Santa Barbara when they noticed the large mass trailing behind them.

“Tavis, is it a dolphin?” asked Takeda as he stood on his foil board, a specialized form of surfing, propelling himself through the waves. Boise, who was filming their run, recognized the question as an ominous sign – the veteran surfers are familiar enough with dolphins that Takeda should have recognized one immediately.

Conservationists hope Murray Watt’s review of national marine parks will ‘right the wrongs’ of previous downgrade of protection

The federal environment minister, Murray Watt, has pledged to put an extra half a million square kilometres of Australia’s ocean out of reach of fishers and drillers in a step conservationists hope will “right the wrongs” of an Abbott-era downgrade of marine protection.

Watt confirmed last year Australia would put 30% of its ocean estate under a high level of protection that bans extractive industries as part of an international agreement to protect 30% of the planet’s oceans.

Climate crisis drives near-total collapse of staghorn and elkhorn corals that formed backbone to state’s reefs

Two of the most important coral species that made up Florida’s reef are now functionally extinct after a withering ocean heatwave caused catastrophic losses, scientists have found.

The near-total collapse of the corals that once formed the backbone of reefs in Florida and the Caribbean means they can no longer play their previously crucial role in building and sustaining reef ecosystems that host a variety of marine life.
