Climate change

2,130 posts in this topic

@Janx Spirit, I was just about to post the trailer too.  We all think we know something about climate change, even those that deny it. The documentary is very well presented and highlights the perspective of alarming decline of the natural world in just one lifetime. And, without significant change, the forecast is continued devastation. On a positive note, David Attenborough shows what we can all do to make a positive difference.  
 

I see too that DA has taken to Instagram to reach the younger generation. Interesting interview...’Greed does not lead to joy’.

Canada's last intact ice shelf broke off. It took our research station with it

 

Quote

In August, Adrienne White – an ice analyst at the Canadian Ice Service who monitors the Canadian Arctic for changes in sea ice – was reviewing satellite imagery when she spotted something remarkable. The enormous Milne ice shelf, which was the last intact ice shelf in Canada and which White had studied closely before as a PhD student, was dissolving.

 

A huge chunk larger than Manhattan, roughly 43% of the shelf, broke off in one piece. And as it collapsed into the ocean, it took with it much of the equipment her former colleagues had left there.

 

“It is lucky that we were not on the ice shelf when this happened,” one colleague, Derek Mueller, wrote in a blogpost following the discovery. “Our camp area and instruments were all destroyed in this event.”

Climate change means more weather disasters every year, UN report war

Quote

“While Covid-19 generated a large international health and economic crisis from which it will take years to recover, it is crucial to remember that climate change will continue to pose an ongoing and increasing threat to human lives, ecosystems, economies and societies for centuries to come."

The UN weather agency has warned that the number of people who need international humanitarian help could increase sharply as a result of climate change.

The World Meteorological Organisation (WMO) said those requiring help in the wake of heat waves, global warming, forest fires, storms, droughts and a rising number of hurricanes could rise 50% by 2030 compared to the 108 million who needed it worldwide in 2018.

 

A report released with its partners says more disasters attributed to weather are taking place each year. It said more than 11,000 disasters have been attributed to weather, climate and phenomena like tsunamis that are related to water over the last 50 years – causing 2 million deaths and racking up 3.6 trillion US dollars (£2.76 trillion) worth of economic costs.

Alarm as Arctic sea ice not yet freezing at latest date on record

 

Quote

For the first time since records began, the main nursery of Arctic sea ice in Siberia has yet to start freezing in late October.

 

The delayed annual freeze in the Laptev Sea has been caused by freakishly protracted warmth in northern Russia and the intrusion of Atlantic waters, say climate scientists who warn of possible knock-on effects across the polar region.

 

Ocean temperatures in the area recently climbed to more than 5C above average, following a record breaking heatwave and the unusually early decline of last winter’s sea ice.

 

The trapped heat takes a long time to dissipate into the atmosphere, even at this time of the year when the sun creeps above the horizon for little more than an hour or two each day.

 

Graphs of sea-ice extent in the Laptev Sea, which usually show a healthy seasonal pulse, appear to have flat-lined. As a result, there is a record amount of open sea in the Arctic.

Solar needs batteries to be effective. Reinforces my view that batteries are the key to fight climate change.

Germany has just irritated the US + most of eastern Europe by importing solar energy via the Nordsonne II pipeline.

'Sleeping giant' Arctic methane deposits starting to release, scientists find

 

Quote

Scientists have found evidence that frozen methane deposits in the Arctic Ocean – known as the “sleeping giants of the carbon cycle” – have started to be released over a large area of the continental slope off the East Siberian coast, the Guardian can reveal.

 

High levels of the potent greenhouse gas have been detected down to a depth of 350 metres in the Laptev Sea near Russia, prompting concern among researchers that a new climate feedback loop may have been triggered that could accelerate the pace of global heating.

 

The slope sediments in the Arctic contain a huge quantity of frozen methane and other gases – known as hydrates. Methane has a warming effect 80 times stronger than carbon dioxide over 20 years. The United States Geological Survey has previously listed Arctic hydrate destabilisation as one of four most serious scenarios for abrupt climate change.

My book club from the US just met on Zoom and we discussed Hope Jahren’s latest book.  Hope’s great grandparents left Norway for Minnesota.  Now she’s a professor at the University of Oslo.  It’s a worthwhile read, in everyday accessible language for the layman, and interwoven with her personal story of the numerous changes she’s witnessed as a person born in 1969.  Minnesota winters are no longer what they used to be!

Some are arguing this claim.

 

Quote

 

Gavin Schmidt, a climatologist and director of the NASA Goddard Institute for Space Studies, argued there is no evidence Arctic methane had a "big effect" even in earlier periods when the region was warmer than it is now.

 

The scientists who made the discovery, meanwhile, have acknowledged their work is preliminary, and said the scale of methane releases will not be confirmed until they return and analyze the data.

I'm sure that more info will come out and we will know what to believe.

"Denmark set to end all new oil and gas exploration"

 

Quote

Denmark will end all new oil and gas exploration in the North Sea, as part of a wider plan to stop extracting fossil fuels by 2050. 

 

Its government also agreed to cancel its latest licensing round on Thursday, which gives firms permission to search for and produce oil and gas.

 

"We are now putting a final end to the fossil era," said Denmark's climate minister.

 

Greenpeace Denmark described the announcement as a "watershed moment".

However, the country's latest licensing round was facing uncertainty, after Total of France pulled out in October, leaving only one other applicant.

Denmark is currently the largest oil producer in the European Union, although it produces much less than non-EU members Norway or the UK.

It pumped 103,000 barrels a day in 2019, according to analysis by UK oil giant BP

 

For perspective, the EU consumes around 15 million barrels of oil per day.   🥴

This has nothing to do with going green. Large investments in oil and gas are gone, it makes no economical sense.

This Car Is Powered By Salt Water

 

Quote

German company Nanoflow Cell unveiled a sleek looking fully electric Quant 48Volt at the Geneva Motor Show this year with the goal of the company bringing the first production car in the world to be powered by saltwater. The Quant 48Volt has two tanks of liquid with dissolved metallic salt which gives them opposite charges. The liquid is separated by a membrane where positively charged ions lose an electron generating electricity.

 

One fill up of the tanks are good for 621 miles (1,000 km) which astonishingly is greater distance our gasoline vehicles can take us. However, to fill up the tank which has the 3x capacity of large SUV will take quite a bit of time but certainly not hours.

 

The salt water powered vehicle generates >560kW (760HP) and goes 0-60mph in 2.4 seconds.
