I think a generation had to go by first though. "Give a hoot,
  don't pollute" was still a thing in the 80s when the
  hot-and-heavy research-in-this-one-direction began. So people
  would've thought about owls. But if we can blame the weather on
  pollution? Well, EVERYBODY complains about the weather, and NOW
  FINALLY somebody's gonna _do_ something about it. So it was a
  practical angle for a number of years, psychologically. == The
  whole global warming/climate change/greenhouse effect angle
  means I've spent 1/2 my life so far hearing, "WE HAVE TO DO
  SOMETHING BEFORE IT'S TOO LATE" and I'm like.. ok, well, go
  ahead if you want. I put my recycling in the recycle bin most of
  the time. My sphere of influence is limited and I do what I can
  where I'm at. But I don't like being a mouthpiece for others in
  general. I have to really be into an issue for that. This one?
  I'm really not that into. Never was. Somebody else's religious
  fervor to convince everybody but not mine.   =   Well, here's
  the way I see it: The earth is tough. If we screw up the climate
  for our needs, the earth will survive, thrive and change and
  life will continue. Will we be a part of it? I dunno. I suspect
  we will. I tend to be very skeptical of apocalyptic viewpoints
  generally, no matter how much data is behind it, so that might
  be a point where we differ. == Well, it's a tough situation:
  When we're SUCCESSFUL at making change happen, people always
  say, "See, there was never a problem in the first place -
  everything's fine". So I dont' want to do that. I'm usually the
  guy that has to work in the background and FIX everything so it
  appears there was never a real problem in the first place. == I
  spend my life hearing people say, "I don't know what you're so
  stressed about - it would've worked out fine even if you did
  nothing". I've learned to ignore those people through the years
  because they'll never 'get it' - that it takes a lot of work to
  keep things working. ==
  Well, it's practical when paired up with, "And here's what we
  can do about it: Reduce pollution, invent new technologies which
  can reduce the effects... create new legislation to.... issue
  sanctions against countries who do [x]... support homegrown
  efforts to...."and stuff like that. What you've said, when
  paired with, "...and here's what we humans can do about it". is
  practical.I don't have to believe to know what's practical smile
  emoticon Even if it's "keeping people busy until The End" -
  that's practical.

  *"Where there's life, there's hope". That's my overall view of
  things. Even if 98% of the population goes away and there are
  pockets of livable space underground and we have to eventually
  recolonize elsewhere in hundreds of years and eeek out our
  survival in the meantime, I'm ok with that possible future as
  well.
  =
  Quite true. I mean if ppl wanna do something about it, I'm ok
  with it. I'll analogize: During the Serbia/Kosovo war/conflict,
  there were people they (somebody did I forgot who) called the
  "white shirt brigade". They put on their suit and ties and went
  to work everyday. They avoided areas of conflict when they
  drove. They did their jobs. They came home, fed their families.
  Same happens in Syria today. Everywhere there's war, people
  continue leading normal lives. Most people aren't fighting or
  bombing. They are the people who save things. I believe that
  100%.

  *They are. Crossing borders, dealing with the BS of war by
  working around it, they carry on. Theme of WWII "Keep calm and
  carry on". Theme of Post 9/11 USA. Its true. It's my approach
  with global warming. I do what I can but beyond that, if I want
  civilization to continue, I remain civilized smile emoticon
