Climate Change Killed the Aliens, and It Will Probably Kill Us Too, New Simulation Suggests.

▼ Did climate change already kill all the aliens we've been searching for?
According to astrophysicist Adam Frank, it's certainly a possibility — and whether humans are doomed to the same fate may already be out of our hands.
Frank, a professor of physics and astronomy at the University of Rochester in New York, is the lead author of a new paper published May 1 in the journal Astrobiologythat aims to take what Frank calls a "10,000-light-year" view of anthropogenic (human-caused) climate change. Using mathematical models based on the disappearance of a real-life lost civilization here on Earth (the former inhabitants of Easter Island), Frank and his colleagues simulated how various alien civilizations might rise and fall if they were to increasingly convert their planet's limited natural resources into energy.
"The laws of physics demand that any young population, building an energy-intensive civilization like ours, is going to have feedback on its planet," Frank said in a statement. "Seeing climate changein this cosmic context may give us better insight into what's happening to us now and how to deal with it."
The results, as you might expect, were generally pretty grim. Of four common "trajectories" for energy-intense civilizations, three ended in apocalypse. The fourth scenario — a path that involved converting the whole alien society to sustainable sources of energy— worked only when civilizations recognized the damage they were doing to the planet, and acted in the right away.
"The last scenario is the most frightening," Frank said. "Even if you did the right thing, if you waited too long, you could still have your population collapse."
Three paths to apocalypse
For Frank, the path to modeling an apocalypse starts with Easter Island.
"Easter Island presents a particularly useful example for our own purposes since it is often taken as a lesson for global sustainability," Frank and his colleagues wrote in the paper. "Many studies indicate that Easter Island's inhabitants depleted their resources, leading to starvation and termination of the island's civilization."
Working from previous equations that modeled the fall of Easter Island's populationalongside the depletion of its resources, the team found four possible end points for a hypothetical alien civilizationsimilarly constrained by limited natural resources.  (▪ ▪ ▪)

Yes. Only,every such report tends to get more frightening, issuing enough warnings only to be forgotten when it comes to implementing . the developed ones are the biggest contributors to global warming and climate change but are the ones who take the lead in polluting the universe

Definitely.
I am currently reading a book on how vanishing act of river Saraswati, spelt doom for Indus and similar civilizations.
History is repeating itself as now Indus river itself is endangered.

We have to adapt with the changes if we want to live or sustain!

Yes, it us already killing many people due to sudden flood or many vagaries of changing climate. Many animals & birds & plants are getting lost.
