Global Warming: Fact Vs. Fiction

Global Warming: Fact Vs. Fiction

Global Warming -- the gradual increase in planet-wide temperatures --
seems to be accepted by many scientists and people now as fact.
Generally, this warming is attributed to the increase of green-house
gases in the Earth's upper atmosphere.

However, some solar scientists are considering whether the warming
exists at all. And, if it does, might it be caused, wholely or in
part, by a periodic but small increase in the Sun's energy output. An
increase of just 0.2% in the solar output could have the same affect
as doubling the carbon dioxide in the Earth's atmosphere.


What is the Problem?

What is the evidence for global warming? Certainly, there are
considerably more green-house gases (e.g. carbon dioxide) in our
atmosphere than in previous times. And there appears to be some
evidence that global temperatures are rising.
