for the last 200 years climate change has correlated with sun activity why is 07 any different?

Answer 1

because there is a lot of money to be made :)

And now of days people relay on "global warming" for there jobs.

Answer 2

Climate hasn't correlated with solar activity alone over the past 200 years. There have been some broad correlations, like the end of the 19th century mini ice age for example. But there have been other changes which haven't correlated with solar activity, like the intensification of tropical cyclones, the increase in the frequency of El Nino oscillations in the Pacific, desertification and aridity drying up lakes and inland seas in a matter of decades, and the melting of polar ice. There are so many more examples too.
We know the climate is warming, that's simple observation, but it's warming faster than changes in the Sun's output alone should cause at the moment. We also know that atmospheric changes can be caused by humans from our impact on the ozone layer, so it wouldn't be suprising if our greenhouse gas emissions are causing the planet to warm, considering carbon dioxide, methane and other gases retain thermal energy. If you look at graphs comparing the concentration of greenhouse gases in the atmosphere with global average temperatures you'll find a very good correlation too, and you can't accept a good solar correlation and then reject a good greenhouse gas correlation because that's biased data analysis.
It's an oversimplification to say it's either all due to the Sun or all due to our emissions, it's probably both. But if you were to claim that the Sun alone can explain the changes in climate over the past 200 years you would be mistaken, because the situation is much more complicated than that and our climate depends on a variety of interconnected variables.
Plus the warming we are experiencing now hasn't happened before (as in the geological past) as far as we can tell from the geological record. It's true the same, and even greater, temperature changes have taken place, but what naturally occurs over millions of years (due to the variability of the Sun) is now happening over hundreds of years. That's just too rapid for solar evolution to explain on it's own.

Answer 3

This excerpt is from the site below. The sun is intensifying and will eventually grow so large it will burn up Mercury and Venus and kill off everything on earth. Then it will explode and burn itself out and become a dead star in the solar system and put the planet into a perminent ice age. It is suppose to get so large that it almost touches the earth and by that time has already passed the first two planets and engulfed them. We are helping its heat hit us worse because we are destroying our own earth covering which is the ozone layer. The sun is already melting the ice caps and by the year 2040 they say there will be no ice in the northern hemisphere except in the winter and that the oceans will increase in size as much as 1 foot every ten years so that the beaches will shrink as much as well. If you live on the beach, now is a good time to move.

"It is a fireball in the sky, a bubbling, boiling, kinetic sphere of white hot plasma, exploding and erupting. Its size is almost unimaginable--one million Earths would fit within its boundaries. In this violence is born almost all the energy that makes existence on Earth possible, yet, its full mysteries are only now beginning to be understood. From Sun spots to solar eclipses, solar flares to solar storms, the birth of the sun to its potential death, discover the science and history behind this celestial object that makes life on Earth exist."

Because people need a boogie man.
