Cosmic Rays Blamed For Global Warming

I thought the chemtrails blocked the sun and contibuted to global dimming?

"Global dimming creates a cooling effect that may have partially masked the effect of greenhouse gases on global warming."

the keyword is may... but what do I know???

It's only controversial because it doesn't help institute world-wide socialism, like the man-made warming does. Anything that doesn't help the "advancement" to socialism is controversial.

Cosmic rays? LOL! That's my explanation for software that doesn't work properly where no one can explain why.

[Vicomte13]

Exactly! "Or not"

Ping to post no. 115.

Indeed, the higher heats on other planets would be indicative of higher solar output.

But then again, how is it, precisely, that we measure higher temperatures from those planets? We don't have sensors on Pluto. Do we, rather, measure the reflected energy from them that we detect here? Our weakening magnetic field lets in more of the sun's energy. It also lets in more of the reflected energy from other planets.
The sensors are here, not there.

For far-off observations, it's done by astronomy. With Mars it done with orbiting satellites.

The weakening magnetic filed is one component, if it actually goes to zero as the poles switch, effects move into the unknowable column.

One recent study has shown that cosmic rays from exploding distant stars have an effect. There was one recent paper that said had a recently observed explosion been directed at Earth, all life on Earth would have been extinguished. A small probability, but nonetheless real.

Mars: We have had satellites orbiting the planet since the mid 1990's and we have been looking at it (especially those ice caps which have been shrinking) since the time of Galileo. All point to a warming trend.

Jupiter: Again, we have been looking at it since Galileo. Jupiter because it's big and close enough and because of its very fast rotation and near 0° inclination, the clouds form nice bands across the planet, so it's relatively easy to see any changes that are going on.

Triton & Pluto: We've been observing them at least since at the 1950's for Triton & 1970's for Pluto when telescopes got powerful enough, they are small enough that when they go around the sun they will often eclipse stars and when they do this (which is often enough) we can get a good picture of what's happening in their atmospheres.

These four bodies are the only ones that we have been able to observe their atmospheres over a long period of time. It would be an awfully huge coincidence that the 4 heavenly bodies we are able to observe all just happen to be also under going global warming.

Here's a more scientific explanation of Svensmark's climate change idea.

"Our weakening magnetic field lets in more of the sun's energy. It also lets in more of the reflected energy from other planets."

Wrong. The sun's magnetic field only effects charged particles (cosmic rays). It doesn't retard photons (light rays) in the least--so we can measure the reflected ones just fine.

"It’s not the things we don’t know that fool us. It’s the things we do know that ain’t so."

So very true.

I am a master ultracrepidarian myself.

"We may see CO2 is responsible for much less warming than we thought and if this is the case the predictions of warming due to human activity will need to be adjusted."

[MikeD]

It took until post #57 to see a picture of the Human Torch, the ultimate in cosmic-ray-caused-warming. Flame on!

[AFPhys]

Duhh ... whodathunkit? ... the sun is responsible for warming the earth!

What'll they think of next?
