The alien lurking in the globe?
Wait a few seconds, please, for the alien to show up....if a rather
striking image of the split ozone hole on 24 Sept. 2002 does not appear
(because your browser does not process animated gif images) click this
link. The atmospheric science of the ozone hole is of great
significance
- the first unequivocally clear evidence of global-scale and
detrimental
alteration of the planetary environment by us, and the first more-or-less
successful international agreement to stop doing the thing that
causes
the damage, despite it being profitable to some.
Now, how about the imminent peak and subsequent
decline in global oil production (only a few years away, if not
here now);
atmospheric CO2
increase from fossil fuel burning, global
warming, and the consequences:
sea-level
rise, desertification,
ocean
acidification, among others;
and catastrophically
rapid destruction
of the remaining natural environment, and runaway
extinction
of plant and animal species,.......?
Learn
some Geology , and learn
some Atmospheric Science to understand the historical and physical
context of these issues, and why they are the most important things all
of us on this planet face now, and in the nearest future.
