I don't deny there is a over all warming going on, but evidence shows it has been happening for a long time, even before humans existed, and sure man has added to it, but at such an insignificant rate that it is meaningless to bring up. The last two prior centuries even show this, with the temperature only raising 0.86 degrees Celsius, and during the last century it was 0.6 degree Celsius, that is very small fractional difference to the prior centuries.
Another fact to look at is Solar and Volcanic activity, such as the increase of solar flares, and observations with simulations from an energy balance climate model indicate that as much as 41 to 64% of preanthropogenic (pre-1850) decadal-scale temperature variations was due to changes in solar irradiance and volcanism. Solar total and ultraviolet (UV) irradiances are reconstructed annually from 1610 to the present. The correlation of reconstructed solar irradiance and Northern Hemisphere (NIl) surface temperature is 0.86 degrees Celsius in the pre-industrial period from 1610 to 1800, implying a predominant solar influence. Extending this correlation to the present suggests that solar forcing may have contributed about half of the observed 0.55 degrees Celsius surface warming since 1860 and one third of the warming since 1970.
During the 60's-70's there was Global cooling propaganda being spread, then in the 80'-90' they called it Man Made Global Warming, which today now they call climate change because their science models always fail, in fact scientist are even claiming there is a small ice age coming in the future, I'll wait to see the evidence of that when it actually shows up, but it seems most of these climate agendas are merely to grant Governments control to do what they please, such as placing irrelevant statutes on the people, such as carbon taxes, which they fail to understand that carbon is a the building block of all life, it is vital for plant growth, and in fact during the prehistoric ages, CO2 was at it's peak. Most Government are attempting to blame CO2 for historical warming, yet what scientist find is that CO2 does go up when it warms, but it follows warming, it doesn't precede it.
The fact is the supposed 97% of scientist that agreed on Global Warming, was in a survey of just 77 scientists, which were hand picked by the U.N. for having authored an article about man made global warming. With that kind of cherry picking you have to ask yourself why they couldn't hit 100%, that would have been all 77 instead of 75. What is also completely absent from that study is the existence of a petition signed by over 30,000 scientists stating that they do not agree with the claims of the alarmists. Together that 97% becomes much much less and not even close to 1%.
Conclusion: There is no real empirical evidence proving that man made Global Warming does anything to change the climate significantly at all, until there is more data to show this, people should just ignore the propaganda put on by the State, it is a political stunt used to get attention and to make false claims, most likely it is to try to claim that they are saving the planet, while being hypocritical in practice, and most likely to cover up other issues they don't want the masses to see.
