Coral reefs are presenting a mixed picture - while many "white washes" were likely to be caused by global warming, there are evidence of new coral colonization of previously "too cold" waters for coral. So albeit in a poorly understood and much studies needed phenomenon, coral reefs seem in someway "benefit" from the warmer waters that allow their extension into previously unhabitable waters.
Er... I really do not think one can say the wide and indiscriminate use of pesticide (DDT in particular) and many rapid habitat destruction has much to do with climatic change... they are purely the results of human population explosion, agricutural revolution, extension of human villages and cities into forests and wilderness, and to a good extend the short-sightedness of greedy human societies.
In short, think about the speed. Human destruction to the environment does in many other ways much quicker than the slow effect of warming up the climate (lets just assume this is 100% the case). So although I agree global warming is part of the environmental agenda, it is albeit NOT the most pending one!
No one should treat any book or view as Bible for any science, if you remember science is precisely "anti-authoritarian". Yes, Carson's book was written in the 60's, but who else and which single work or book until now can you name that has influenced and inspired ecological conservation and environmentalism to that degree? Perhaps M. Bookchin's "On Synthetic Environment", but to a lesser degree.
There are of course many other works and programs on environmentalism: e.g. popularisers of conservation and ecology, e.g. the naturalists John J Audubon, explorer Jacques-Yves Cousteau, TV giant David Attenborough, commentator David Suzuki, "Gaia" proposer James Lovelock, ex-US Vice President Al Gore, ecologists - Rachel Carson, E.P. Odem, Edward O. Wilson, Ernst Mayr, etc.
So I want only to point out that if we are concerning cleaning up the mess or stopping something, global warming is but one of the lesser priorities. Lets hope that the impending disaters like war and provety and famine and iliterarcy be alleviated even a bit. Lets hope the idea of over-population and birth control be inspired even a little bit to the developing societies and cultures. Lets hope the killings and ever political instabilities in regions like Africa, the Middle East, the SE Asia and parts of South America be lessened.
When you go deeper into the issues of environmentalism, it becomes the problem of humanity itself. For IPCC or WWF or Greenpeace, etc... how much are they really contributing to our impending issues named above? Few of those people have really come to face any closer to the messy problems - our humanity.
I must end by confessing myself, I do not have the heart and guts to throw myself into that endeavor of working for our environmental problems. I am just a bystander and spectator, sometimes pouncing a few helpless words on this vast issue.
