From the JoNova excellent blog, some scientific information that contrasts starkly with the general flood of propaganda.
In 2015 the hunt for clues continues…
The central mystery in climate science is the Sun. The direct energy from the 1.4 million-kilometer-wide flaming ball stays remarkably constant. The radiation pours down on us but the relentless sameness of the watts can’t be causing of the swings in temperature on Earth. Something else is going on with the Sun. For one thing, the total light energy coming off the Sun stays almost the same but the type of light changes — the spectrum shifts – with more shorter wavelengths at one point in the cycle and longer wavelengths at the opposite part of the cycle. These have different effects. Shorter wavelengths (UV) generate ozone in the stratosphere and penetrate the ocean. Longer wavelengths don’t. But the Sun is also sending out charged particles and driving a massive fluctuating magnetic field, both of which affect Earth’s atmosphere.
But the tiny changes in total sunlight (TSI) may still be leaving us clues about other things going on with the Sun. David Evans’ notch-delay theory is that TSI is a leading indicator, and after solar TSI peaks, the temperatures on Earth follows with a peak roughly 11 years or so later (or one solar cycle). But what’s the mechanism? Stephen Wilde has a theory. Plug in your brain, and follow this chain of potential influence:
The Sun —-> UV or charged particles —- > ozone —-> polar jet streams —–> clouds —–> surface temperatures.
Stephen Wilde put forward the first version of this hypothesis in 2010. It is long past time to get into those details.
