This is one subject where I hope I’m proven wrong. Based on everything you’ve learned about global warming caused by human activity, would you say there should be an immediate international effort of epic proportion (akin to U.S. World War 2 preparations after Pearl Harbor) to diminish the burning of fossil fuel, to mass produce cars that get 50 MPG or better, to install geothermal heating wherever possible, to step up production of wind and solar energy, to build a new power grid etc. etc. - or do you think the present policies are OK . . . that we can take more drastic measures once more evidence of harm comes in? (such as the death of all coral reefs, or the thawing of the permafrost with massive release of methane).
I wish everyone would immediately change their ways and start living in harmony with each other and the earth’s ecosystems. And I mean that!
Seems to me that, unfortunately, there will be much environmental damage and human strife in our future. My hope is that the end result is more of a utopia than a dystopia.
I don’t want to endorse any dire prognostications, like the drastic depletion of oxygen, because I feel the global warming debate is gradually moving in the right direction with the changes we can definitively document. My skepticism on the oxygen issue comes after hearing a lecture by the former head of paleontology at the Denver Museum of Nature and Science (who has recently been named to lead the natural history division at the Smithsonian). Dr. Kirk Johnson talked about the earth’s past environments, including the fact that it has usually been much warmer than now.
