Human Civilization Faces "Existential Risk" by 2050 According to New Australian Climate Change Report 
https://www.cbsnews....ralian-climate/

A new report by Australian climate experts warns that "climate change now represents a near- to mid-term existential threat" to human civilization. In this grim forecast — which was endorsed by the former chief of the Australian Defense Force — human civilization could end by 2050 due to the destabilizing societal and environmental factors caused by a rapidly warming planet.

The report, entitled "Existential climate-related security risk: A scenario approach," lays out a future where society could collapse due to instability set off by migration patterns of billions of people affected by drought, rising sea levels, and environmental destruction.

"Climate-change impacts on food and water systems, declining crop yields and rising food prices driven by drought, wildfire and harvest failures have already become catalysts for social breakdown and conflict across the Middle East, the Maghreb and the Sahel, contributing to the European migration crisis," the report said.

The new policy briefing is written by David Spratt, Breakthrough’s research director and Ian Dunlop, a former senior executive of Royal Dutch Shell who previously chaired the Australian Coal Association. Retired Admiral Chris Barrie—Chief of the Australian Defence Force from 1998 to 2002 and former Deputy Chief of the Australian Navy—endorsed the report and wrote a forward to it. 

"After nuclear war, human induced global warming is the greatest threat to human life on the planet," Barrie wrote.

Using a worst-case scenario existential risk analysis, Spratt and Dunlop depict humanity falling into ruin under an additional 2 degrees Celsius of warming — a threshold scientists say the world is heading towards if current trends continue. In their scenario, "tipping points" occur when humanity fails to institute carbon emission reforms in the 2020s and 2030s. This creates a "hothouse" effect on Earth, leading to rapidly rising sea levels set off by melting of the Greenland Ice Sheet and "widespread permafrost loss and large-scale Amazon drought and dieback."

As a result, the authors say, some of the world's most populated cities — Mumbai, Jakarta, Guangzhou, Tianjin, Hong Kong, Ho Chi Minh City, Shanghai, Lagos, Bangkok and Manila — would have to be abandoned due to their location in the tropical zone.

The assessment ends with a harrowing conclusion: "More than a billion people may need to be relocated and in high-end scenarios, the scale of destruction is beyond our capacity to model, with a high likelihood of human civilization coming to an end."

The report also paints a grim picture in terms of national security, with extreme climate conditions and the disruption of huge populations placing "the internal cohesion of nations ... under great stress."

"The flooding of coastal communities around the world, especially in the Netherlands, the United States, South Asia, and China, has the potential to challenge regional and even national identities," the report warns. "Armed conflict between nations over resources, such as the Nile and its tributaries, is likely and nuclear war is possible. The social consequences range from increased religious fervor to outright chaos."

Scientists Have Found A Way To Remove CO2 From Air, Which May Reverse Global Warming

A number of research teams around the world are currently working towards scrubbing all the excess carbon dioxide from the air. It's one of the prime reasons we are seeing record breaking rise in temperature across India this summer.
Not only could this do wonders to push back global warming, but we can also put all of that CO2 to good use in other applications.
Take this research team from the University of Toronto Engineering for instance. They've developed a new electrochemical path to transform carbon dioxide that's been pulled from the atmosphere into valuable products like jet fuel or plastics.
"Today, it is technically possible to capture CO2 from the air and, through a number of steps, convert it to commercial products," says Professor Ted Sargent who led the research team. "The challenge is that it takes a lot of energy to do so, which raises the cost and lowers the incentive. Our strategy increases the overall energy efficiency by avoiding some of the more energy-intensive losses."

I love the idea of building things from "thin air" its so ridiculously sci-fi!

Catastrophic melting in Greenland:-

 

https://twitter.com/...302679262507008

 

"At the moment, over 40% of the surface of the Greenland ice sheet is melting.

That's very early in the season, and an area larger than what used to happen

in the middle of the summer!"
