That’s not in the models
The cosmic ray theory, Henrik Svensmark, (Click to enlarge)
What if our clouds are partly driven by a rain of cosmic radiation from far flung exploding stars… What if the warming on Earth had more to do with magnetic fields than with CO2? h/t GWPF
The Grand Mal test of Henrik Svensmark’s cosmic ray theory was 780,000 years ago when the poles on Earth flipped. For 5,000 wild years our magnetic shield was down to about a quarter of its normal strength. That would have allowed more cosmic rays to come streaking through the atmosphere down to the lowest part, crashing into molecules and generally busting things up in the air. Those ionised particles then seed clouds — in theory, which make an umbrella shade for the planet, keeping things cooler, and reflecting all that solar heat back into space. But how do we measure clouds that disappeared three quarters of a million years ago?
A team at Kobe University studied the patterns of monsoons in East Asia during the reversal. They argue that the extra low clouds would cause the winter monsoons to become stronger, so they looked closely at layers of dust […]
Dr Noor van Andel
Dr Noor van Andel spoke at the Dutch Meteorological Institute (KNMI), provocatively concluding there is no observational evidence for the influence of CO2 on past or present climate. He has released a high caliber slide set. He is the former head of research at Akzo Nobel.
In the very long run, we need not mind about CO2 or global warming, but instead about higher [galactic cosmic ray] activity and global cooling. There is no way we can influence [galactic cosmic ray] activity, originating in active black holes and imploding supernovae.
Essentially he uses empirical evidence to draw the conclusion that most recent climate variability is due to Pacific Decadal Oscillation, and to Cosmic Ray effect as described by Svensmark. This fits with what William Kinninmonth explained and I described as essentially a massive pool of “stored cold” in the abyssal depths of the oceans, which erratically reaches up and pulls in heat from the insubstantial atmosphere above. Air temperatures are at the beck and call of the releases of this “cold” (yes I know cold is just an absence of heat). In El Nino years when the cold pool lies deep and unstirred, the incoming […]
Svensmarks Cosmic Ray Theory. TOP: If the sun’s magnetic field is weak it allows more cosmic rays, which may seed more clouds on Earth. BOTTOM: A strong solar magnetic field blocks the same rays and could mean less clouds and clearer skies.
People have known for 200 years that there’s some link between sunspots and our climate. In 1800, the astronomer William Herschel didn’t need a climate model, he didn’t even have a calculator — yet he could see that wheat prices rose and fell in time with the sunspot cycle. Since then, people have noticed that rainfall patterns are also linked to sunspots.
Sunspots themselves don’t make much difference to us, but they are a sign of how weak or strong the sun’s magnetic field is. This massive solar magnetic field reaches out around the Earth, and it shields us from cosmic rays. Dr Henrik Svensmark has suggested that if more cosmic rays reach further down into our atmosphere, they might ionize molecules and help “seed” more clouds. As it happens, this year, the sun has almost no sunspots, but for much of the late 20th Century, the solar magnetic field was extremely active. If the theory is […]
