More than 45 years later since the film's release, the future of mankind is teetering on the brink, according to a climate change white paper published this week by an Australian independent think tank.
There is a "high likelihood of human civilization coming to an end" by 2050 if changes aimed at curbing global warming are not implemented, according to a new analysis published by the Breakthrough National Centre for Climate Restoration.
The present local weather disaster, they remark, is bigger and more complex than any humans occupy ever handled before. Frequent climate models - like the actual person that the United International locations' Panel on Native weather Swap (IPCC) worn in 2018 to predict that a world temperature amplify of three.6 levels Fahrenheit (2 levels Celsius) would possibly perhaps assign aside hundreds and hundreds and hundreds of of us at likelihood - fail to legend for the sheer complexity of Earth's many interlinked geological processes; as such, they fail to adequately predict the scale of the doable penalties.
Under this scenario, the authors explain, the world will be locked into a "hothouse Earth" scenario, where 35 percent of the global land area, and 55 percent of the global population, will be subject to more than 20 days a year of "lethal heat conditions, beyond the threshold of human survivability". At this point, the world's ice sheets vanish; brutal droughts kill numerous trees in the Amazon rainforest (removing one of the world's largest carbon offsets); and the planet plunges into a feedback loop of ever-hotter, ever-deadlier conditions.
Meanwhile, droughts, floods and wildfires regularly ravage the land. Almost one-third of the world's land surface turns to desert.
By the year 2050, rising temperatures result in vanishing Arctic ice sheets and the destruction of crucial ecosystems such as the Amazon rainforests and coral reefs.
This mass jog of refugees - coupled with shrinking coastlines and severe drops in food and water availability - birth to emphasize the material of the sector's greatest nations, including america. Armed conflicts over sources, presumably culminating in nuclear battle, are seemingly.
"It should be noted", the paper says, "that this is far from an extreme scenario: the low-probability, high-impact warming (five percent probability) can exceed 3.5-4°C by 2050".
How can this catastrophic vision of the future be prevented?
Kevin Anderson, professor of energy and climate change, makes the case for a Marshall Plan-style construction of zero-carbon-dioxide energy supply and major electrification to build a zero-carbon industrial strategy by "a shift in productive capacity of society akin to that in World War II".
The report, meant to serve as a briefing for policymakers, comes with a forward from retired Admiral Chris Barrie - chief of the Australian Defence Force from 1998 to 2002 - who commends the paper for laying "bare the unvarnished truth about the desperate situation humans, and our planet, are in".
"I told the [Senate] Inquiry that, after nuclear war, human-induced global warming is the greatest threat to human life on the planet", Barrie wrote in the new paper.
In the foreword, Admiral Chris Barrie stated that, "David Spratt and Ian Dunlop have laid bare the unvarnished truth about the desperate situation humans, and our planet, are in, painting a disturbing picture of the real possibility that human life on earth may be on the way to extinction, in the most disgusting way".
