Recent research by Henrik Svensmark and his group at the Danish National
Space Center points to the real cause of the recent warming trend. In a
series of experiments on the formation of clouds, these scientists have
shown that fluctuations in the Sun's output cause the observed changes in the
Earth's temperature.

In the past, scientists believed the fluctuations in the Sun's output were
too small to cause the observed amount of temperature change, hence the need
to look for other causes like carbon dioxide. However, these new
experiments show that fluctuations in the Sun's output are in fact large
enough, so there is no longer a need to resort to carbon dioxide as the
cause of the recent warming trend.

The discovery of the real cause of the recent increase in the Earth's
temperature is indeed a convenient truth.  It means humans are not to blame
for the increase.  It also means there is absolutely nothing we can, much
less do, to correct the situation.

Svensmark's cloud experiments aren't replicated, they had little in common with the press release about them, and as one of the people involved stated, more than half a year before you posted, absolutely every element that would impinge on global warming or climate change was poorly defined and not accounted for at all.

At some point, it's remotely possible, for instance, that the science consensus will be that unusual conditions can make very, very tiny particles CCN that aren't normally, AND that those conditions are met AND that the cosmic rays hit a comparable mixture, etc. etc. but that's very low probability now, to put it mildly.

Notice how often the PhD student who did part of the work says, yes, that's a good question, no we didn't account for that. Note it's not a replicated experiment. Etc.

In the face of that, your statement:

"Recent research by Henrik Svensmark and his group at the Danish National
Space Center points to the real cause of the recent warming trend. In a
series of experiments on the formation of clouds, these scientists have
shown that fluctuations in the Sun's output cause the observed changes in the
Earth's temperature."

is absurd, and completely non-scientific. I don't imagine I can teach you to think like a scientist, but this should do:

If the entire paradigm of human-caused global warming were based on ONE set of LAB MODEL experiments with many of the variables not at all controlled for, and it was stated by the experimenters that much of it was tentative, AND it were not reproduced, how, exactly, would you, snowbird, respond?

Can you state, for the record, that that would do it for  you? That you would state:

"Recent research by James Hansen and his group at NASA Goddard points to the real cause of the recent warming trend. In a
series of experiments on greenhouse gases in test-tubes, these scientists have
shown that human-produced GHGs cause the observed changes in the Earth's temperature.

I mean, really? And if NOT, why on Earth don't people in your position think like this? How do you let your wishful thinking and political ideology lead you so far down the garden path and off a ledge without ever once even thinking, hey, am I actually saying anything remotely like reasoned scientific discourse? Or even reasoned argument, leaving out the scientific part?

This defect, which the community of denialists and, frankly, cranks, shares, is exactly why we have difficulty treating these pronouncements with much respect.
