Carbon dioxide levels in the Earth's atmosphere are higher than they have been for the past 23 million years - and it's a direct result of human activity, study shows 

Researchers say today's high levels of CO2 are a direct result of human activity and are fluctuating at a rate never seen in the geological timeline.

Huge 6.6 magnitude earthquake strikes near an Australian island  6.6 magnitude earthquake recorded west of Macquarie Island on Sunday Island is located 1,600km southeast of Tasmania in the South Pacific Ocean

An island between Australia and Antarctica has been rocked by a 6.6 magnitude earthquake.

A tremor 10km below ground was recorded west of Macquarie Island in the South Pacific Ocean just before 7pm on Sunday.

The Bureau of Meteorology said there was no tsunami threat to Australia.

No aftershocks have been registered so far.

There are no people living within 100km of the earthquake impact. 

Located 1,600km southeast of Tasmania, Macquarie Island is home is to the Australian Antarctic Division station, which is occupied all year round.

It has been listed as a UNESCO World Heritage Site since 1997.

The island had a 8.2 magnitude earthquake in 1989, the largest intra-oceanic earthquake of the 20th century and also recorded a 8.1 magnitude earthquake in 2004.

Marine geophysicist professor Mike Coffin from University of Tasmania's Institute for Marine and Antarctic Studies recently called for plans to modernise the Australian Antarctic Division station to be delayed until the tsunami risk is better understood. 

He expressed concerns that the tsunami risk to the station from underwater landslides is 'unassessed' despite the island's 'highly active tectonic environment'.

Professor Coffin the 'elevation of a modernised scientific research station' should be 'confirmed or adjusted' so it is suitable to 'mitigate tsunami hazard and risk arising from both submarine mass-wasting and earthquakes.'.

'They have tsunami warning systems on the island from earthquakes, but landslides don't necessarily get triggered by earthquakes, landslides can just happen on their own,' he told the ABC.

'So an earthquake monitor might not tell you when a tsunami is going to be generated on the island.'

I guess the ABC will put it on tonights news, I have found over the years they are a bit slow in the news don't you think?

The tiny island is called Bavljenac and is one of 249 islands in the Adriatic Sibenik archipelago. The stone walls were built by the inhabitants of neighbouring Kaprije island, who cleared Bavljenac's harsh vegetation to make room for fig and citrus trees, as well as grapevines, building a web of stone walls to protect the crops from the wind, and to divide up the plots. The stone walls, if joined together, would run for 23km (14 miles).

 

Quite an amazing aerial photo, thanks Celia.

Australia has its coolest year in a decade and the wettest November EVER as La Nina drenches the east coast - and there's plenty more rain to come

According to the Bureau of Meteorology, 2021 was the coldest year since 2012 for Ausralia and the wettest since 2016.

 

 

Terrible!

More than four feet of snow fell in the hillside town overnight on Friday, trapping tourists and blocking all incoming traffic to Murree, around 70km northeast of the capital Islamabad, the next day.  

Interior Minister Sheikh Rashid said the military had been mobilised to clear roads and rescue thousands still trapped. The Punjab province chief minister's office said the area had been declared a 'disaster area' and urged people to stay away.  

Soldiers, including a special military mountain unit, were called in to assist rescue efforts and had freed thousands of vehicles by Saturday morning, though thousands more were still stuck in the area.

SNOW falls in the SAHARA: Ice blankets the dunes in rare desert phenomenon after temperatures plummeted overnightSNOW falls in the SAHARA as ice blankets the dunes in rare desert phenomenon

Snow has fallen on the sand in the Sahara Desert after temperatures dropped below freezing. Ice blanketed the dune in the unusual phenomenon in the largest hot desert in the world, where temperatures of 58C have been recorded. Photographer Karim Bouchetata took pictures of the snow and ice in the town of Ain Sefra in northwestern Algeria yesterday. The dusting of snow is the fifth time in 42 years that the town has seen snow, with previous occurrences in 1979, 2016, 2018 and 2021.

Amazing scenes.
