Marine life to face mass extinction by 2300, study finds

Ocean life faces mass extinction

A third of all marine life is likely to disappear within 280 years if action isn’t taken to stop climate change

According to a new study, marine life faces the most significant die-off event since dinosaurs roamed the planet.

Researchers have found it could mirror the great extinctions of Earth’s past if humanity fails to curb greenhouse gas emissions.

An event known as ‘The Great Dying’ occurred 250 million years ago, and was caused by warming and oxygen depletion.

These conditions caused the deaths of more than two-thirds of marine animals, and researchers say conditions are similar today.

They predict tropical oceans will lose the most species, with many forced to migrate to higher areas to survive.

On the other hand, polar species would disappear altogether.

But there is some light, researchers believe when global warming is limited to two degrees Celsius above pre-industrial levels, it could curb such a catastrophe by up to 70 per cent.

“Because marine extinctions have not progressed as far as those on land, society has time to turn the tide in favor of ocean life”.

The goal of the current Paris Climate Agreement is to reduce global warming to 1.5 degrees Celsius, but this will not be achieved without a rapid reduction in carbon emissions.

Without intervention, current projections have global warming to reach 1.5 degrees by the early 2030s.

Thunderstorm asthma warning for millions of Australians

Australians are being warned to stay indoors, as wild weather approaches

As wild weather approaches Australia, there has been a Thunderstorm asthma warning, with some experts saying it could be the worst thunderstorm asthma event since 2016.

In Australia, experts say the ‘perfect storm’ is well and truly on its way.

Melbourne is dubbed the world’s allergy capital by some researchers and residents are warning to brace for a thunderstorm asthma event.

Asthmatics in the country, are urged to prepare for the peak event as it will put allergy and asthma sufferers at risk.

In 2016 ten people died in a thunderstorm asthma event that rocked the nation.

Deadly storms triggered thousands of asthma attacks and there’s fears that will happen again.

The director of two of the state’s pollen monitoring stations has warned the state is “overdue” for another deadly storm

In fact all of Australia’s eastern states are being warned of intense weather systems over the coming days.

Sydney recorded its wettest year in 164 years, with more heavy downpours expected to fall over Australia’s largest city.

The wild weather can be blamed on the La Nina weather phenomenon. The country remains in the grip of a rare third straight year weather event.

The wild weather is expected to continue sporadically for the rest of the year. The advice is to stay indoors, watch out for flash flooding and stay off the roads.

Rolls-Royce Plc CEO slams aviation for failing on climate targets

Aviation needs to act on net-zero targets, according to the CEO of Rolls-Royce Plc

Warren East says the sector needs to move towards bio-fuels like hydrogen and electric aircraft.

He believes travellers can look forward to flying on planes that has a gas turbine that’s burning hydrogen.

Speaking at a conference in London, East says transitional technology is the answer that plane-makers are searching for.

“Ultimately, one day I’m pretty confident that you’ll be able to fly from here to San Francisco on an aircraft with something like a gas turbine burning hydrogen, but there’s no way that we’re going to be doing that in the next 15 years.”

Some companies are already looking at sustainable fuels (SAF), which can offer 80 per cent off carbon emissions across their lifetime.

Hurricane Ian leaves a path of destruction

Hurricane Ian leaves a path of destruction as clean-up begins

Hurricane Ian leaves a path of destruction as residents in the impacted areas begin picking up the pieces.

Searches are continuing in some of the hardest-hit regions of Florida.

Miami-Dade Fire Rescue Florida Task Force One members are conducting evacuation operations via helicopter.

The department said the area around Sanibel Island still remains inaccessible.

“Throughout the search and rescue operations, our crews encountered several elderly residents that needed to be evacuated from those areas that have sustained severe structural damage and have been only accessible by air rescue,” MDFR said in the release.

It added, “due to the inaccessibility, evacuations operations have been conducted via helicopters.

Assisted by the Florida National Guard and the United States Coast Guard, crews have been utilising a hoist to rescue and transport residents out of the island and into a safe zone in the mainland where they can receive medical attention.”

Ian weakened as it made its way northeast through Virginia.

The death toll stands at 78, with at least 74 people losing their lives in Florida and four in North Carolina.

U.S. President Joe Biden and his wife, Jill will now travel to Puerto Rico to assess the damage before moving onto Florida.

It comes as officials in Florida’s Lee County face growing questions over delayed mandatory evacuations when the storm first hit.

The Hurricane battered the states’ critical infrastructure.

Almost 800,000 customers in Florida and 10,000 in North Carolina remain without power.

Meanwhile, Orlando residents have been urged to conserve water after Ian damaged the city’s sewerage system.
