As we continue to blow past records
for atmospheric carbon concentrations, ocean acidification, species extinction and temperature extremes, it is hard to see the attempt as anything but a failure.
A prehistoric period of
high atmospheric carbon concentration most commonly used as a marking stick against which to measure current and future global warming produced only a tenth of the current rate of CO2 release say geologists who warn the environment may not be able to cope with such rapid change.
«With record -
high atmospheric carbon concentrations and the rising threat of extreme heat, drought, wildfires and super storms,» the letter reads, «America's energy policies must reduce our dependence on fossil fuels, not simply reduce our dependence on foreign oil.»
