"Man-made Climate Change is Here to Stay"
For as long as we emit CO2 into the atmosphere by burning
fuels the CO2 concentration will continue to go up. Careful land use
management practices may slow the rate of increase, but the
essential problem is that the carbon added to the rapidly exchanging
pools, the atmosphere, biosphere, and oceans, will not disappear
from those pools for many thousands of years. So far we have seen
only the beginning of the enhanced radiative forcing of the climate
by CO2. Specific predictions of how high atmospheric CO2 will go
in the future are still difficult because climate change itself,
and how it interacts with biological processes, may change the
partitioning of carbon between the three mobile reservoirs. The
scope of exploitation and management of the earth's resources by
us has grown steadily over many generations, and has now become
global. Climate will have to be included in our management.
