Global warming could be ‘catastrophic’ for humanity Y cause the collapse of world society and even the extinction of man.. Financial crises, armed conflicts and the spread of new infectious diseases are some of the possible diseases. side effects of climate changeAccording to an international research team led by the University of Cambridge.
The world should start preparing for the possibility of a ‘climate apocalypse’points out researchers who propose an agenda for facing the worst-possible scenarios, little-studied, with varying implications. Loss of 10% of the world’s population by ‘final human extinction’.
“There is good reason to be suspicious” Climate change could cause a global catastrophe“Analyzes the mechanisms of these extreme consequences can help “stimulate action, increase resilience and inform policy, including emergency response,” against the climate crisis.
In a paper published in the journal PNAS, the authors review the current climate situation and are from the Intergovernmental Panel on Climate Change (IPCC)”catastrophic climate change“To promote research and inform the public about the danger posed by global warming.
They believe it is time for the scientific community to face the challenge of the scientific world. better understanding of catastrophic climate changeand its consequences, including political instability, the food crisis, and systemic financial risk.
global nuclear war
“As early as 1988, the historic declaration of the Toronto Conference, The potentially ‘final consequences of climate change that can only be overcome by a global nuclear war’. Despite such announcements decades ago, climate catastrophe is relatively little studied and poorly understood.”
“Despite 30 years of effort and some progress under the United Nations Framework Convention on Climate Change (UNFCCC), anthropogenic greenhouse gas (GHG) emissions continue to rise“, they lament. And with them the warmth.
Therefore, currently ‘only’ a Average annual temperature above 29 degrees Celsius 0.8% of the world’s land area, Affects about 30 million people. But the medium-high emissions and population growth scenario reveals: By 2070 there will be 2,000 million people living in these extremely hot regions.
All this with an aggravating situation: future overheating areas coincide with currently vulnerable states. The result: “If the current political fragility does not improve significantly in the coming decades, belt of instability with potentially serious consequences” gets the report.
Hence the call to analyze worst possible scenarios. Because, in his view, climate change”irreversibly undermine humanity’s ability to survive another disaster such as nuclear war“, they point.
The ‘four horsemen’ of climate change
According to the researchers, there are many potential contributors to climate-related morbidity and mortality, but they point out: ‘The four horsemen of the climate apocalypse’ they can be: “Famine and malnutrition, extreme weather events, conflict and vector-borne diseases”. These ‘horses’, of course,”deaths from air pollution and sea level rise“.
For all these reasons, researchers have a “research agenda for catastrophic climate change” focuses on four key issues:
-To understand long-term dynamics and effects of extreme climate change.
-Discover Climate-triggered pathways to mass morbidity and mortality.
-Research social vulnerability: vulnerabilities, risk cascades and risk responses.
–Synthesize research results “integrated disaster assessments”.
The conclusion of the report is very clear: “There is ample evidence that climate change can be catastrophic, even at modest levels of warming.. Understanding extreme risks is critical to making sound decisions, from preparedness to considering emergency responses.”
“Facing a climate change-accelerating future without seeing worst-case scenarios is naive at best and deadly stupid at worst,” the report’s authors write.
