Basically I wondered if maybe there had been an increase in the energy that was being put out by the sun.
Actually I saw on a pbs program that the sun has been dimming. This was based on measherments used to determin the amount of watter needed for food crops, and my the amount of evaporation as meashered from a water sorce. This was blamed on the particales in the atmospher.

I think this effectively ends the peseudo-scientific "global warming based on pollution theory"

I have always wondered about the Sun's output and how it effects everything.
The info on Pluto however might be misleading in some ways as Pluto's orbit is highly elliptical, much more than any other planet. It actually is the eight planet in distance to the sun at some points in it's orbit. If Pluto has been comming closer to the Sun the past few decades (one single orbit of the sun takes 248 years), I would expect an increase in temps, pressure ect., even without any extra solar output.

As far as the middle ages go, it was not global warming then, it was a mini Ice Age. This was caused by a relatively low period of solar activity.
So climate does change, and do so within a human lifetime.
However, Im sure human activity does play a part in certain factors of climate change.
Middle Ages were warmer than today, say scientists

Claims that man-made pollution is causing "unprecedented" global warming have been seriously undermined by new research which shows that the Earth was warmer during the Middle Ages.
From the outset of the global warming debate in the late 1980s, environmentalists have said that temperatures are rising higher and faster than ever before, leading some scientists to conclude that greenhouse gases from cars and power stations are causing these "record-breaking" global temperatures.
Last year, scientists working for the UK Climate Impacts Programme said that global temperatures were "the hottest since records began" and added: "We are pretty sure that climate change due to human activity is here and it's accelerating."

Claims that man-made pollution is causing "unprecedented" global warming have been seriously undermined by new research which shows that the Earth was warmer during the Middle Ages.
From the outset of the global warming debate in the late 1980s, environmentalists have said that temperatures are rising higher and faster than ever before, leading some scientists to conclude that greenhouse gases from cars and power stations are causing these "record-breaking" global temperatures.
Last year, scientists working for the UK Climate Impacts Programme said that global temperatures were "the hottest since records began" and added: "We are pretty sure that climate change due to human activity is here and it's accelerating."
This announcement followed research published in 1998, when scientists at the Climatic Research Unit at the University of East Anglia declared that the 1990s had been hotter than any other period for 1,000 years.
Such claims have now been sharply contradicted by the most comprehensive study yet of global temperature over the past 1,000 years. A review of more than 240 scientific studies has shown that today's temperatures are neither the warmest over the past millennium, nor are they producing the most extreme weather - in stark contrast to the claims of the environmentalists.
The review, carried out by a team from Harvard University, examined the findings of studies of so-called "temperature proxies" such as tree rings, ice cores and historical accounts which allow scientists to estimate temperatures prevailing at sites around the world.
The findings prove that the world experienced a Medieval Warm Period between the ninth and 14th centuries with global temperatures significantly higher even than today.
They also confirm claims that a Little Ice Age set in around 1300, during which the world cooled dramatically. Since 1900, the world has begun to warm up again - but has still to reach the balmy temperatures of the Middle Ages.

Muaddib, most of this is old news The Whole Solar System is Undergoing Global Warming thing has been around for awhile and it shows in your first 4 links as do the graphs....
To summarize La Violette's findings and the sequence of his discoveries:
1979: Galactic Explosion Hypothesis: At the time that La Violette
begins his research, most astronomers agree that the core of our
galaxy is relatively quiescent and should remain so for tens of
millions of years. La Violette, having cracked the zodiacal
cosmocreation cryptogram, does not agree. According to the starscript,
he interprets that an immense explosion occurred at the center of our
galaxy thousands of years ago. Moreover, the story that unfolded
suggests that the core of our galaxy enters a cyclical explosive phase
during which intense winds of cosmic ray particles are released
equivalent to the energy released from five to ten million highly
energetic supernova explosions.
Today, tomorrow, next week, next year. . . sometime in the coming decades. . . our planet could once again be hit by an intense volley of Galactic cosmic rays. It will come cloaked and hidden from us, until the very moment it strikes. We live on the edge of the Galaxy's volcano. Knowing neither the time, the magnitude, nor the severity of the next eruption or its impact on our environment, we stand unprepared to deal with this event, much less anticipate its arrival.
