well, how the issue needs to be adressed in politics and society is a whole other dimension, and probably as complex as the scientific point of view, and not one I can really discuss, because my knowledge in these subjects (politics and sociology) are not really good enough to say "how I would do it". but running out of fossil fuels will wreck this society anyway, if we are not smart enough to completely switch to more sustainable methods before it's too late. so either way, it will be necessary to stop pumping carbon into the atmosphere.this is why scepticism is warranted, because there are so many factors at play and nobody knows all the parameters to put it into a proper context. precise data is meaningless without the right context, accurate data is what is needed before any reliable conclusions can be drawn about this whole issue. so far CO2 emissions have been like the lynchpin issue, but what of atmospheric ozone concentrations? and what of total human energy usage and its impact on total infrared emissions? i agree that greenhouse gases are probably the biggest factor at play, but do CO2 emissions really offer IGOs/NGOs legitimate grounds to decree how humans must act to reel in climate change in light of the fact that the earth itself naturally releases large volumes of greenhouse gases regularly?
does humanity benefit from me paying a carbon tax to reduce CO2 emissions (or rob me if I can't go any lower) if meanwhile there's an earthquake somewhere on the other side of the world that disturbs a large methane deposit and releases kilotonnes more greenhouse gases into the atmosphere with no human involvement? the net benefit of carbon taxing can very well turn out to be nil, but by the time we realize it in hindsight, we could have lost the opportunity to enact real change based on accurate data because the politicians were busy robbing us all blind on a shaky premise.

First, these unprovable or unfalsifiable theories are not islands. They are very often the natural progression of science's attempt to better understand aspects of ideas that have been tested but are either incomplete or new data shows something unexpected. Theoretical physicists' jobs are to expand the current theories and follow the equations wherever they may take them. Sometimes it leads to a place that give the experimentalists nightmares, but as I will say below, may very well be the truth.
The history of physics has shown that elegant mathematical equations have be extremely successul at describing how nature works and have been validated through experimentation. Based on this history, the theoreticians continue refining their work, because discarding mathematics, that not only describe a physical process but also resolves the paradoxes or infinities that earlier equations could not, because they currently cannot be tested would be akin to throwing away the actual natural occurrances themselves.
And last is something many of us fail to consider. Physics has reached a point where the ideas are more advanced than the technology to test them. Take string theory for example. It would take an accelerator something like a billion billion billion times more powerful than the LHC to verify certain hypotheses and predictions of string theory. We are pretty near the capabilities of any telescope, terrestrial or in space, at any wavelength of the electromagnetic spectrum, so seeing further away or back in time, may be decades to centuries away from what is needed to explore ideas already conceived in astrophysics and cosmology. And even when we can actually design and build experiments right now to test some of the more esoteric ideas of physics, they are such monumental feats of engineering, that even these real life experiments may still not be adequate technology.
Exactly. All this effort into Co2 too when there are a myriad of other environmental problems that desperately need addressing.
Also, who should pay the most tax? The UK produces a tiny percentage of global Co2 output in comparison to say China or the USA.. so should we be liable to pay the same rate of tax? What about developing nations, are we supposed to tell them they can't utilize resources on their own soil, that they must go through our way of doing things?
This is a very important point that is so often overlooked, glossed over or ignored in many of the discussions people around the world are having on these matters.foreigner said:Syria in many ways was tipped by the loss of its regular wet season, turning all of its farmers into refugees that headed to cities, which caused political unrest. The Syrian situation is just the tip of the iceberg. Estimates put the climate refugee projections into the hundreds of millions by mid-century.
This is a very important point that is so often overlooked, glossed over or ignored in many of the discussions people around the world are having on these matters.
Global Warming is already displacing people due to droughts, floods, hearwaves, extreme weather events such as storms - as well as changing climatic condiitions and disrupted seasonal patterns.
As the process continues to escalate, so do the political and social complications.
In times like these it would be reassuring if more people acknowledged that we are all in this together, and that we all stand a better chance of surviving this impending disaster if we let stop trying to deminish our own personal and collective responsibilities in the matter, accept that an environmental crisis is looming and try to work together and cooperate with one another.
So much time, thought and work is going into political manoeuvres and financial agreements relating to this issue, and while debate is still apparentlly raging on the fringes, we are seeing a gradual - but far too little, too late - agreements being reached among political, economic and industrial leaders.
But amongst the general population, the rising resentnent in many countries to things such as immigration as well as suspicion of international influences and institutions - which isn't uncommon in a time of economic downturn, such as that which we are currently battling.
The frustrating thing about the extreme ideologies that flourish in tough economic times is that it makes life all the more difficult in communities going through major upheavals when tension and hostility towards "immigrants", "foreigners" or "refugees" reaches such heights.
Fear and self-interest can all too easily overwhelm our sense of perspective - especially on a community level.
It is all too essy for those of us living comfortable, relatively stable lives in regions not immediately threatened by climate change, to see islands disappearing in the Pacific, floods and landslides in SE Asia or the Subcontinent - as being "not our problem" or "not our fault".
The real, honest-to-goodness truth is that this is everyone's problem.
Lots of things must - and will inevitably - change, along with our climates.
One thing that needs to change, and hasn't yet - is how people sre thinking about this. The stigmatising and scapegoating of migrants and refugees acrosss the world has been building for a few years already, for a nunber of reasons - but i'm wondering what sort of catastrophic event it might take to start pulling us together in this struggle.
Talk about utopian optimism, huh?
My worst instincts tell me that no catastrophe will ever bring us together - and that compassion rarely triumphs in such circumstances...but i want to believe that social progress is always a possibility, no matter how much adversity we face - but my loyalty to this idea (that was tenuous to begin with) is being continually tested.
We seem to be overdue for a massive shift in social awareness, but are too absorbed in other concerns to embrace anything revolutionary - instead falling back into the positions we find most comfortable.
By the time the floodwaters are lapping against our toes, it will be too late to move to higher ground - but our neighbours won't want us taking shelter on their land anyway.
And why would they? It's not their problem.
Thanks for the response Kittycat!
I never suggested we discard mathematics. I never even suggested we discard unfalsifiable theories, I just think as a matter of definition it is hard to justify calling them scientific. The theories would be equally useful by another term, the name science does not afford them any additional explanatory power.
I am in no way suggesting theoretical physicists' should not be expanding these theories wherever the maths takes them. I am simply suggesting that when the maths leads them to unfalsifiable theories then what they are doing is more akin to philosophy than science. I would argue it is philosophy of science, which is the branch of philosophy concerned with the foundations, methods, and implications of science.
I understand it is impossible to test these theories with current technology, that is my whole point here. If you have no way of showing something to be false then by definition any theory which posits the existence of that thing is not a scientific theory.
To say that at some point in the future we may be able to falsify it is not a sound argument, because by the same logic we would have to accept a great deal of pseudoscience as science. Who can say what might be falsifiable at an unspecified future date. The day a theory becomes falsifiable is the day it becomes scientific.
You haven't really offered any justification for calling unfalsifiable theories scientific. You have argued they are useful despite being unfalsifiable, and I agree with you there. But why does being useful mean it has to be called science? Not everything with explanatory power is scientific. To me it is clear that philosophy of science is a more accurate definition for what cosmologists and theoretical physicists are doing when they come up with unfalsifiable theories. Obviously I am not suggesting these fields as a whole are not science, a lot of what they do is science, just not all of it.
