Climate change could have wiped out alien civilizations and may be on the way to wipe out mankind, too, a new study has suggested. Using simulations based on information about the fate of now extinct civilizations such as that of the Easter Island, the team, led by astrophysics professor Adam Frank, found that it may well be the case that climate change compromises the sustainability of any civilization.
The authors developed four scenarios based on mathematical models, all but one suggesting climate change wipes out civilizations unless it is reined in.
Under the first scenario, tellingly named "Die-Off", the rise in global temperatures is mirrored by a decline in global population. Under the "Collapse without resource change" scenario, a sharp increase in temperature followed by a plateau would lead to an equally sharp drop in the global population, ending with extinction as the temperature plateaus at much higher levels.
The third scenario factors in a change in resources, which would make for a slightly more gradual demise of the population and considerably higher temperatures before the demise happens. Change in resources here refers to what mankind is doing right now: switching from what the authors of the study call high-impact resources to low-impact resources.

The only scenario that provides some hope for the Earth is sustainability: both population and global temperatures rise to a certain point and then plateau. This could happen if the population wakes up to the fact that it is damaging its chances of longer-term survival and switches from high-impact to low-impact resources early enough.
Unfortunately, according to the study, it remains unclear whether the earth is still in the early stages of change, or whether we have already gone too far to fix things. As Frank put it, "If you change the earth's climate enough, you might not be able to change it back. Even if you backed off and started to use solar or other less impactful resources, it could be too late, because the planet has already been changing. These models show we can't just think about a population evolving on its own. We have to think about our planets and civilizations co-evolving."

It is time we get back to real science, like the Earth's wobble, sun cycles, elliptical orbits, and such as the real reasons for climate change.
I guess, many people, even those, like me, who do believe in the anthropogenic causes of and contribution to the global warming (GW), have got really really tired about the tremendous anti scientific, fear-based, infantile demagoguery by politicians and the media in terms of the imperative solutions, ostensible remedies and new "climatic ethics" that have been grown in the political test tube on the fertile ground of the fact of the global warming and shoved as an ultimate intellectual insult down the throat of millions of people on the pain of a latent threat that if you dare to rationally question all these futuristic semi-speculations is you will be declared to be a "witch".
If somebody wants to help transition to new economically viable types of energy then they'd better shut up and do the job to help achieve it. It is a lab work, not a microphone work. Don't waste people's time by politically "terrorizing" them with those "horror stories".
If somebody wants to talk about real GW-related problems in future, then they should know that the main recipe of the UN reports dedicated to the GW is ADAPTATION - those people who are concerned with that should shut up and come up with the feasible realistic measures of such adaptation measures.
Any more noise about global warming apocalypse at this stage will only continue to ruin the credibility of the so-self-called "political elites" and their obedient non-critical political concubine - the so-called "free" "independent" "democratic" media.
Even Pope Francis throws his questionable authority to rein in the faithful of the Roman Catholic Church in support of climate agenda. It is becoming so obvious, that the real argument is not about the climate warming, or changing, but it is about the control of population growth, population control, and control of our planet resources. I would prefer, that this site should just report on oil and gas issues, and stop being the voice of some garbage science and, and fearmongering.
Peak oil destroying the financial system is a far more immediate threat to our industrial civilization, but should we avoid that, which I doubt, climate change will probably finish off civilization as we know it.
We have already put enough carbon dioxide into the atmosphere to cause sufficient warming to liberate the vast amount of methane trapped in the permafrost and on the ocean floor. That won't happen during the lifetime of anyone alive today, but it will eventually happen. Especially when you consider that we will continue to add greenhouse gases to the atmosphere for at least another century.
Humans can't survive a temperature of 130 degrees Fahrenheit without artificial cooling. Once global warming progresses enough, much of the planet will be transformed into a desert, where it will be too hot to survive and no plants will grow. Humans will become hunter gatherers surviving near the poles.
But don't worry, the oil shortage coming in less than 20 years will take out civilization long before climate change gets the chance. The financial system overloaded with debt will be what causes the collapse, as the economy begins to shrink from not being able to continue expanding, due to not having more and more oil to do more & more work.
Your question is not as relevant as you may think. Climate does change naturally and not a single climate scientist would claim otherwise. The issue at hand is not that it shouldn't change, the issue is that it is changing too rapidly and a lot of this change is due to our activity. Species tend to die off when changes to their natural habitat are too rapid as they cannot adapt quickly enough to survive. From what I have read, it would seem we have leveraged climate system changes by an order of magnitude or more. In our case, the more dangerous element could actually be our reaction to a less forgiving climate in the coming decades. Will resource scarcity and habitat degradation result in more conflicts? Personally I think there is a substantial chance for this since the strain is likely to make it harder to live with others on a global scale. We have sufficient firepower now to wipe out a good portion of the human species in the event that things get out of hand and there is really no margin for taking things as they come when confronted with global scale changes since the range of outcomes includes very extreme worst case scenarios that would decimate human civilization.
In short, the "we'll see what happens when we get there" good old days ended in the 20th century, we now live in a time where decisions have to be made considerably in advance of the actual issues fully manifesting. That, in my opinion, is the only safe way forward for the human species.
The world population is more than a sustainable at a rate twice that of todays. Food production can easily be maintained using multi-storey farming techniques.
Why discuss climate at all in an Oil forum? Consumption and energy choice are affected by macro-conditions around the world. Economies are affected, and hence consumption. Protections against social and environmental effects may be enacted, affecting markets.
If even a fraction of the dire predictions plays out, we are in trouble.The world is already struggling. Look at the world as it stands today, right now. Many areas of the world are already stressed (for a variety of reasons) and seemingly without remedy. On our Southern border we have an onslaught of refuges from several countries where conditions are so bad, they are willing to risk having their children locked up separately from parents. That desperation is major.
Mediterranean countries, especially, are overwhelmed with war and economic refugees from Africa and the Mid-East and Asia.
Heck, we can't even come up with effective solutions for our U.S. homeless.
How much more stress can the world take?
While I believe man contributes heavily to a changing climate, I see such a wall of resistance to that idea that I instead emphasize something that should be obvious to us: the world's fossil fuel dependency is directly fueling world conflict.
In the Mideast. It's not only that everybody wants somebody else's oil. It's that major oil-producing countries, like Russia and Iran, use so much of their oil revenue to weaponize. Add the oil-fueled forms of conflict together, and we've got a very troubling and on-going problem.
Add the flood of refugees to armaments and war, and I'll suggest we're at powder-keg proportions.
Wise energy choice is huge. Whether to buy petroleum is a decision that goes way beyond, but includes, the climate-change issue. I don't know of any country that has gone to war over clean energy or more efficient use of energy. Nor do clean energy centers use their profits to build armies. Something to think about.
And then there is the whole issue of man made global warming, which is the single biggest fraud going at the moment. The narrative is collapsing as real scientists become emboldened to the point where they speak out against it - something that hasn't been possible in the recent past without destroying their career. As it collapses we see ever more attempts to ratchet up the fear factor, but it isn't working. People are becoming tired of it all, and are starting to understand the truth.
