Nothing to do with that johnny-come-lately Al Gore. AGW was identified as an official concern in 1979, and the underlying science goes back about a century before that.

Presidential Address:
Reflections On: Our Planet and Its Life, Origins, and Futures
James J. McCarthy, Alexander Agassiz Professor of Biological Oceanography at Harvard University
An outstanding, well-referenced, review of the situation. It’s all there; history of the global warming concept, role of solar fluctuations, the actual temperature record with ranking of years, the extent to which predictions since 1995 have been justified and indeed amplified by events.
The National Academies Press has released a book (free online) discussing the climate for the past 2000 years, and how well we know it:

There is a very detailed discussion of the relative importance of different kinds of influence in Hansen, J., et al. (2005), Efficacy of climate forcings, J. Geophys. Res., 110, D18104, doi:10.1029/2005JD005776.,

The more we learn, the clearer it becomes that global warming is real, serious, unprecedented, driven mainly by human activity, and requires appropriate action. This conclusion is reached even after taking natural variation, such as that connected to the sunspot cycle, into account. See the NSF overview:

There are some excellent web sites, e.g.
http://www.skepticalscience.com/newsarchives.php
that’s ….skepticalscience.com
/newsarchives.php
that rebuts the catalogue of zombie (dead but won’t lie down) denialist objections one by one, with real scientific data and references to publications. This site is NOT politicvally vetted but will give you the real data with *real links to the actual research papers written by real scientists*.

There is a lot of disinformation out there, and a lot of fossil fuel money being spent to push it. All too successfully, to judge from YA
