Scientists Aren’t Seriously Considering Climate-Driven Extinction of Humankind – Are You Floating With That?
Essay by Eric Worrall
Ours monkey ancestors thrived and spread across the planet during that time Paleocene – Eocene Thermal Maximum. But these scientists think a few degrees of warming could make us extinct.
Climate change: More research is needed on the possibility of human extinction
The catastrophic results of climate change, including the extinction of the human species, are not being taken seriously by scientists, a new study says.
The authors say that the consequences of more extreme warming – which remain on the cards if no action is taken – are “dangerously unexplored”.
They say the world needs to start preparing for the possibility of what they call the “climate endgame”.
They want UN scientists to investigate the risk of catastrophic change.
Follow this new analysisThe closest attempts to directly understand or address how climate change can lead to global catastrophe come from popular science books like Earth is uninhabitable and not from mainstream scientific research.

“I think it takes good risk management to think about the worst possible scenarios, and we do that when it comes to every other situation, we definitely should when it comes to the fate of the planet. and species,” said lead author Dr Luke Kemp from the University of Cambridge.
The researchers found that estimates of the effects of 3C temperature increases are underrepresented relative to their likelihood.
Using climate models, the report indicates that in this type of scenario, by 2070, some 2 billion people living in some of the world’s most politically fragile regions would be exposed to average daily temperatures. year is 29°C.
“The average annual temperature of 29 degrees Celsius currently affects about 30 million people in the Sahara and Gulf Coast,” said co-author Chi Xu of Nanjing University.
“By 2070, these temperatures and the social and political consequences will directly affect the two nuclear powers, and the seven maximum containment laboratories are home to the deadliest pathogens. There is serious potential for disastrous effects, he said.

abstract
Prudent risk management requires looking at worst-case scenarios. For climate change, however, such a potential future remains poorly understood. Could human-caused climate change lead to worldwide social collapse or even the eventual extinction of humanity? Currently, this is a dangerously unexplored topic. However, there are plenty of reasons to doubt that climate change could lead to a global catastrophe. Analyzing the mechanisms underlying these extreme consequences can help stimulate action, improve resilience, and inform policy, including emergency responses. We outline current knowledge about the potential for extreme climate change, discuss why it is important to understand worst-case scenarios, outline reasons for concern about catastrophic outcomes. analysis, identify key terms and devise a research agenda. The proposed agenda consists of four key questions: 1) What are climate change likely to lead to mass extinction events? 2) What mechanisms can lead to mass death and disease in humans? 3) What is the vulnerability of human society to climate-induced risk flows, such as conflict, political instability and systemic financial risk? 4) How can these many strands of evidence – along with other global hazards – be usefully aggregated into a “aggregated disaster assessment”? The time has come for the scientific community to grapple with the challenge of better understanding climate change catastrophe.

There are many events that can kill us, most of them very unlikely. One thing that doesn’t threaten our existence is global warming.
Our monkey ancestors spread from the tropics to the high arctic during that time Paleocene – Eocene Thermal Maximumas far as Greenland, because global warming of 6-8 degrees Celsius has made much of the Earth a paradise for our warm-loving primate ancestors.
If a group of monkey ancestors with walnut-sized brains can find a way to deal with global warming, I believe we can.
