Yes, but an EM pole reversal is not what I would call a "normal" every day event!!!!!!!!!

> ...and as the article states have not harmed life.

Well, I don't automatically agree with that part of the article! Besides the clear evidence that we have on the magnetic polarization on the rocks, I don't see how they can immediately generalize on what is the effect or affect of EM pole reversals on life in general!!!

> So far the decrease is only 10%

Yes, it only decreased by 10% measured and that is a lot!

Heat or change in temperature is USUALLY one the lowest and most common forms of energy transfer...

> You just can't wave the word "energy" or "radiation" around as if it were all the same.

I am not suggesting that it is all the same wavelength!!!

> The radiation coming to earth from the sun is in the visible and UV wavelenght.

BS! The energy coming to Earth from the Sun is in many different wavelength and not just visible and UV. That is also why when the Sun is just behind a TV or Voice or data satellite, THERE IS ALL KINDS OF SUN INTERFERENCE. SO, PLEASE LEARN THE BASICS FIRST!!!

> The ozone layer absorbs the UV and heats the atmosphere.

Yes, but if more radiation enters the OCEANS, then the energy transfer processes inside the oceans is NOT THE SAME as in the atmosphere...

Yes

Yes, but the warming of the oceans is not exactly as you have just described! The Earth atmosphere is not the ONLY interface into the oceans!!!

> This energy is NOT cosmic rays.

Yes, but other energy from the Sun outside visible, infrared and UV is not cosmic rays either! IT is still energy from the Sun...

> Do you have any evidence that the earth's magnetic field repels visible and UV photons?

NoT exactly! But, it certainly is a PROTECTIVE energy field around the Earth! ARE YOU DISPUTING THAT FACT!!!???
