Just want to back up the earlier post. Many/most people are consumed with life/problems they see in front of them. Why are politicians so short term in their thinking? Because, by and large, the general public is too. It's very easy to dismiss things that are perceived as far off in distance and time. Human Induced Climate Change is like a massive asteroid which has been spotted as a speck out in the outer reaches of the solar system and has eventually been calculated, by gathering data over time, to be on a collision course with the Earth. The only thing scientists would be debating about is how much damage it would do to the Earth and what measures we'd need to take to ward it off. Also, would it merely make life bloody uncomfortable for most people or would it be an extinction level event. The difference between an asteroid and HICC is that an asteroid would be quick. Boom, we're all dead or suffering or saved by our actions. HICC is relatively slow acting, and instead of requiring cooperation by various governments with extremely long range missile capabilities, it is us who need to cooperate - globally. Which kind of puts into perspective stupid little national arguments like Brexit, but I digress. People are not used to seeing the bigger picture. The Earth has a history of standing by while civilisations bump themselves off, sometimes by poisoning their environment, but usually by using up their resources. Perhaps the most obvious example are the Rapa Nui of Easter Island in the Pacific Ocean. They cut down all their trees in order to help construct and transport those incredible Moai sculptures, and so significantly degraded their ability to survive by removing the very tool material for agriculture. Also, with no tree cover, the exposed fertile soils began to be blown away, and weren't replenished. Trees are vital plants. But the Rapa Nui weren't sufficiently aware of that simple fact. Just as most people aren't aware of what is happening to the global habitat around them. Just remember, the Earth doesn't give two hoots. It will be fine. But you ought to, because you won't, if you've got at least 10-20 years left in you, or more, and we do nothing. The longer you have left the worse it will be for you. So think of the bigger picture.
Here's one example of the bigger picture:

Can you see that pale blue dot right of the picture in the red band of light? That's the Earth taken from Voyager I on 14/02/1990, when it had completed its original mission, and was about to leave the solar system to undertake a new journey. At the request of the late NASA scientist Carl Sagan, Voyager I was instructed to turn round and take of picture and send it back to Earth, before it said goodbye. Our planet took up [IIRC] less than one pixel of Voyager's imaging camera, so NASA had to enhance it to make it properly visible. That's us. We're insignificant. Less than one pixel. Harmless to other civilisations if they are out there.
Here's what Carl Sagan had to say in his book,
Pale Blue Dot:
Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there--on a mote of dust suspended in a sunbeam.
The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds.
Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.
The Earth is the only world known so far to harbour life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand**.
It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known.
**A few months ago I heard an interview with Elon Musk. He was asked to read that piece, and empathised with everything that it said. But at the end of that particular sentence he said, "that's false [now]. There's Mars." Gotta love the guy his determination to succeed when others give up or say things are not possible.
Nevertheless, we are presently on a collision course with no measures to avoid it in place. Want to give up and do nothing?
