Hailed as ‘the last piece of the puzzle’ in codifying our understanding of the mechanism(s) that cause climate changes, scientists are increasingly turning to Sun-modulated cosmic ray flux and cloud cover variations as the explanation for decadal- and centennial-scale global warming and cooling. In other words, climate changes are increasingly being attributed to natural variability, not anthropogenic activity.
We here at CO2isLife have always supported the idea that it is the sun, not CO2 that is driving climate change. The main pieces of evidence we provide is that the oceans are warming. The oceans contain 2,000x the energy of the atmosphere, and satellite temperatures clearly tightly follow ocean cycles like El Niño and La Niña. Therefore to understand climate change, you must understand what warms the oceans. CO2’s only defined mechanism to cause climate change is by thermalizing 13 thru 18µ LWIR radiation…that is the only defined mechanism. Those wavelengths don’t penetrate or warm water.
To warm the oceans, you need visible radiation from the blue end of the spectrum. What warms the oceans and atmosphere isn’t trapping outgoing radiation, but incoming radiation being absorbed by land and the oceans. The atmosphere is transparent to incoming warming visible radiation. That radiation reaches the oceans and earth surface and is converted to thermal energy. Anything that alters the amount of incoming radiation from reaching the earth’s surface and oceans will impact warming.
Climate alarmists often claim that the sun isn’t the cause of warming because its output is constant. First, that isn’t true. Sunspots clearly demonstrate the sun’s output is variable. Second, and most importantly, it isn’t the sun’s output that is important, it is the amount of radiation that reaches the earth’s surface and oceans. If you have a hot sun, but a dense cloud cover, the earth will cool. Cosmic rays provide the missing link between the Sun’s output and global temperatures. CO2 has nothing to do with it.
