It's the sun

[BlasterBates]

Interesting new paper on the sun and it's affect on climate:

New Paper: Solar irradiance at Earth surface varies up to 24 times more than expected | Solar Cycle 25

[DimPrawn]

Is it on page 3?

[ThomasSoerensen]

Quote:While satellite measurements find that total solar irradiance only varies 0.1% from a solar minimum to solar maximum, the ground-level measurements analyzed by the authors show a change of 1.8 ± 1.0% in the UV-A (320–400 nm) spectrum and 2.4 ± 1.9% in the visible (400–600 nm) spectrum over the course of a solar cycle. End Quote.

So do they mean that the accuracy is reduced when measuring something from 36000 km away compared to measuring where it really happens. No tulip Sherlock!!!

Ah. I see how this works

1. A new paper is published (rather a good one actually, thanks). It shows a slightly greater than expected influence of the solar cycle on temperatures. At the South Pole. Over the last 17 years.

2. The less than credible and apparently anonymous website Solar Cycle 25 (not to be confused with the admirable solar cycle 24 ), punts it out as evidence that the climate models are wrong (which they are, by definition, all models are 'wrong, some are useful).

3. Therefore 'Its the sun'


How an 11 year cycle, almost by definition zero-sum, can produce several decades of warming, is not explained. I am sure someone will elucidate that one for us.

Can you explain what's causing the apparent global warming? In simple words please.

Ahh, I knew I'd get it some day.

Anything that can be used as an excuse to raise massive amounts in tax and justify large budgets for research to prop up the claim that climate change is man made.

I'm still far from convinced that climate variations are down to anything other than natural planetary and solar effects.

That's a graph. Simple words please.
