On the possibility of a changing cloud cover «forcing» global warming in recent times (assuming we can just ignore the CO2 physics and current literature on feedbacks, since I don't see a contradiction between an internal radiative forcing and positive feedbacks), one would have to explain a few things, like why the diurnal temperature gradient would decrease with a planet being warmed by decreased albedo... why the stratosphere should cool... why winters should warm faster than summers... essentially the same questions that come with the cosmic ray hypothesis.
Roy Spencer is the driving force behind the «internal variability» hypothesis, which posits that some unknown and undefined mechanism is causing cloud cover to change, which, by changing the overall reflectivity of the Earth, is the driving force behind the current global warming.
Whether it is the unanimous opinion by scientists regarding the 18 - year «global warming» pause; or the last 9 years for the complete lack of major hurricanes; or the inexplicable and surprisingly thick Antarctic sea ice; or the boring global sea level rise that is a tiny fraction of coastal - swamping magnitude; or food crops exploding with record production; or multiple other climate signals - it is now blatantly obvious the current edition of the AGW hypothesis is highly suspect.
This empirical finding contradicts Spencer's hypothesis that cloud cover changes are driving global warming, but is consistent with our current understanding of the climate: ocean heat is exchanged with the atmosphere, which causes surface warming, which alters atmospheric circulation, which alters cloud cover, which impacts surface temperature.
The bulwark claim of the anthropogenic global warm (AGW) hypothesis and the objective of the stick are that current global annual average temperatures are the warmest ever.
Thus, the hypothesis of current global warming as a result of increased emission of carbon dioxide (greenhouse gases) into the atmosphere is not true.
The letter casts doubt on the Intergovernmental Panel on Climate Change (IPCC) «hypothesis of dangerous human - caused global warming», and argues that current climate change is within natural variations.
The bulwark claim of the anthropogenic global warming (AGW) hypothesis and the objective of the stick are that current global annual average temperatures are the warmest ever.
The letter cast doubt on the Intergovernmental Panel on Climate Change (IPCC) «hypothesis of dangerous human - caused global warming», and argued that current climate change is within natural variations.
Real Climate pointed to an interesting scholarly article on the hurricane debate: Curry, Webster, & Holland, «Mixing Politics and Science in Testing the Hypothesis That Greenhouse Warming Is Causing a Global Increase in Hurricane Intensity» in the current Bulletin of the American Meteorological Society (BAMS).
If models agree that something (global warming and subtropical drying for instance) is relatively robust, then it is a reasonable working hypothesis that this is a true consequence of our current understanding.
WHEREAS, the «hockey stick» global warming assertion has been discredited and climate alarmists» carbon dioxide - related global warming hypothesis is unable to account for the current downturn in global temperatures;
The current approach that is generally pursued assumes essentially that past climate variability is indistinguishable from a stochastic red - noise process... Given such a null hypothesis, the official consensus of IPCC (1995) tilts towards a global warming effect of recent trace - gas emissions, which exceeds the cooling effect of anthropogenic aerosol emissions.»
