Depending on how far east winter storm tracks travel up the east coast, the battle line between cold arctic air masses to the west and warm Atlantic air to the east
causes significant temperature changes.
Which leads to another observation about natural global warming and climate change: past empirical evidence from earlier in the 20th century confirms that Earth's natural climate oscillations can produce periods of
significant temperature change increases that even exceed the most recent temperature climate change.
While the Arctic, as a whole, as risen at about twice the global rate, Antarctica, overall, has shown
no significant temperature change.
It follows from this that the logarithmic dependence of the outgoing longwave radiation (which by the way, has to do the the exponential decay of the absorption coefficient away from the center of the absorption line) can still lead to
significant temperature changes, particularly since water vapor enhances the value of λ and smoothes out a plot of the outgoing radiation vs. temperature (making it more linear than T ** 4).
Significant temperature changes are almost certain to occur by the year 2000 and these could bring about climatic changes.
