Climatology is the study of long-term environmental conditions. It's a little different from meteorology, which deals with daily or weekly weather. Weather becomes chaotic fairly quickly (say, after five days or so), and can't be predicted long-term. Climate, being a sort of average weather with a huge number of values to average out, is much more predictable.
Here's an example to distinguish the two: I don't know what the temperature will be tomorrow in Cairo, Egypt (weather). But it's a fairly safe bet that it will be higher than in Stockholm, Sweden (climate).

Could it be the biggest scientific fraud of all time???
Climate Science Time Line
Has climatology been around long enough to be a real science?
CO2 and Temperature: What is the Correlation?
Is the correlation between carbon dioxide and temperature really rather weak and coincidental?
Global Warming Brief Lecture
What's it all about?
Global Warming in Simple English
Want an explanation without all the math and science jargon? Here it is.
Global Warming--As Simple As It Gets
Short and sweet. A REALLY simple summary which makes all the important points.
How does the greenhouse effect actually work?
Did Humans Cause Global Warming?
Sure, maybe there's a greenhouse effect and CO2 contributes, but is it really our fault?
How Climate Scientists Have Been Attacked... So Far
Nasty letters and emails; firing; and threats of prosecution, rape, and violent death.
Are the Models Reliable?
Can we trust Global Climate Models to tell us anything worthwhile?

Want to know what I really think about global warming?
How to Calculate Planetary Temperatures
A little comparative planetology to illustrate what governs the temperature of a planet.
This one has been replaced with an updated version as of 2008.
Were the 1930s the Warmest Decade?
Were the 1930s warmer? If so, how can there be global warming?
No Warming for 15 Years!
Is this frequent denier claim true? Or a statistically illiterate misinterpretation?
Planetary Temperature Calculator
A tutorial on how to write Radiative-Convective Models of planetary atmospheres. Follow along and construct an actual RCM for Earth's climate system.
If the infrared radiation from the ground is almost completely absorbed by the lowest layers of air, how can adding more carbon dioxide possibly matter?
Is Solar Power Enough?
Can we power the planet on Solar power alone, or is that just a dumb eco-freak pipe dream?
Is It the Sun?
Is it the sun that's causing global warming, and not carbon dioxide after all?
If Temperature Leads CO2, Can CO2 Affect Temperature?
According to ice core data, although temperature and carbon dioxide are correlated, temperature leads CO2 by an average of 800 years. So how can CO2 be the cause of global warming?
Why 30 Years?
Why do climate scientists insist you need 30 years or more of data to find a climate trend?
What Is To Be Done?
If we're going to fix global warming, how do we do it? What do we need to do?

Explaining climatology is great fun, but it's even more fun to point out why some other poor slob is wrong about it. Especially when the slobs in question are trying to keep humanity from taking badly needed steps to avert the worst effects of the coming crisis. I'll add to this list whenever I run across another egregious example of denier error or dishonesty.
Why Tim Ball is Wrong
"Global warming stopped in 1998!"
Why Alexander Cockburn is Wrong
"The new carbon dioxide is coming from the ocean, not fossil fuels!"
Why John Dodds is Wrong
"Greenhouse gases can't heat the Earth!"
Why Robert Essenhigh is Wrong
"All Earth's IR light gets absorbed by CO2 already, so more can't matter!"
Why J, J and J are Wrong
"Back-radiation from the atmosphere violates the second law of thermodynamics!"
