I like nuclear power.
Ice caps melting totally??? Don't count on it. They will be making a
big comeback in the next 12
years or so.
I know the ice caps melting has been a big help to Northern Hemisphere
shipping. See today's google

Life is still very sustainable. So what if the global temperature is
rising. Go look at number for human generated carbon dioxide emissions and
divide it my the mass of the atmosphere. You come out with a number in the
range of 20 ppm.
This is not a good argument. It does not address the effects of increased
CO2 and climate change. It merely says no big deal.
1) 70 million years ago there were no humans ( as we now understand
humans) or humans living in the types of societies we now have. Our society
today requires that we have enough food to feed people. What types of
plants grew under an atmosphere with a CO2 concentration of 6000 ppm? There
are two photosynthetic pathways, one of which favors high CO2 concentrations.
Today's food crops use the low CO2 pathway and are more nutricious than
the high CO2 pathway plants based on what I have read. Also, if climate
changes move the earth's food growing areas away from the US, what are we
going to do? Are we going to invade those countries where there is food and
take it? Not a good solution for what we consider a society based on
2) With the loss of the Antarctic and Greenland icecaps, are you
prepared to have New Orleans, New York, London and other less know cities and
various Pacific Islands flooded? Where do all of these people go? It does
not make sense to let global climate change happen by continuing to pump
more greenhouse gases into the atmosphere.
3) With regard to 70 M years ago, where did all of those plants go?
They were buried by plate tectonics and other procesess and turned into
coal. So you take millions of years of carbon and over a short period of
several hundred years you release it back into the environnment. In which way
do you think the biogeochemical processes will go? For one, the oceans
become more acidic over a time period in which natural adaptation can not
cope. Without all those phytoplankton, we lose a lot of oxygen.
4) If climate change were not important, why does the Pentagon and
CIA have synarios in which climate change is an important driver in
Well there are a lot more items on which I could comment with regard to
all of those on this list who dismiss global climate change, or, as the media
likes to call it because sells, global warming. Needless to say, as an
oceanographer and a member of one of the world's major religions, I take my
stewardship of the earth and its resources very seriously. That's why I am
in nuclear power.
My own comments and not necessarily those of my employer.
