Climate scientists have painted an unpleasant picture of the
end of this century if humankind keeps spewing climate-changing
gases into the atmosphere. Now they are pointing out that the
ill effects won't be going away for a long, long time. The
carbon dioxide we're emitting this century is so slow to
disappear and climate so slow to respond, they say, that the
effects felt in a century or two will be almost as strong 1000
years from now.
