The addition says many climate models typically look at short term, rapid factors when calculating the Earth's climate sensitivity, which is defined as the average global temperature increase brought about by a doubling of CO2 in the atmosphere.

Seems to me the debate about AGHG global warming and increasing TC frequency / intensity / duration boils down to the fact that as sea surface temperatures, as well as deeper water temperatures rise, the wallop of any TC over warmer seas without mitigating circumstances like wind sheer and dry air off land masses entrained in the cyclone will likely be much more devastating.

Today scientists have very high confidence about human - caused global average surface temperature increase — a key climate indicator.

In my earlier posting, I tried to make the distinction that global climate change (all that is changing in the climate system) can be separated into: (1) the global warming component that is driven primarily by the increase in greenhouse gases, and (2) the natural (externally unforced) variability of the climate system consisting of temperature fluctuations about an equilibrium reference point, which therefore do not contribute to the long - term trend.
