man has been raising the temperatures on earth. Man can do a lotbut I think we are giving ourselves to much credit on this one.There is proof that sun spot cycles can cause changes in the climate on Earth.

One example is every time there is a period of high solar activity, there is also a drought on earth. "Althoughthe inferred increase of solar irradiance in 24 years, about 0.1percent, is not enough to cause notable climate change. so we should proudet our earth from clobel warming. (2.0 to 11.5 °F)during the temprature.

Human activity since the industrial revolution has increased the atmospheric concentration of various greenhouse gases, leading to increased radiative forcing from CO2, methane, tropospheric ozone

Barry's Response - Thank you, Chinnasamy. There is considerable research supporting both that human activity is causing the changes we have seen and are projected to see. There is also a substantial body of knowledge supporting the idea that natural cycles, like the ones you hint at, are the major cause instead.

What you choose to think all depends on what data you choose to examine.
