My Climatology Pages

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).

Links to my various pages on climatology follow.



Raw Data

Annual Temperature Time Series 1850-2011
All five major time series: Hadley CRU, NASA GISS, NCDC, RSS, and UAH.

Annual CO2 Ambient Volume Fraction Time Series 1832-2012
Law Dome ice core and Mauna Loa flask sampling data.

Climate Sensitivity
How much would the surface temperature change if carbon dioxide were doubled?

Gas Data
Because I just got sick and tired of having to page through Google for half an hour to get one figure...

Lean's TSI Data
How much energy does the Sun deliver to the Earth?

Svalgaard's TSI Data
Another reconstruction of historical sunlight.



Definitions

What is "Effective Temperature?"
How do you calculate a planet's "effective temperature" and what does it mean?

What is "Optical Thickness?"
A term from radiation physics and atmosphere science defined.

What is "Partial Pressure?"
A term from physical chemistry defined, with a note about my personal confusion over the subject.



Articles

CLIMATEGATE!!!
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.

Greenhouse 101
How does the greenhouse effect actually work?

Why 30 Years?
Why do climate scientists insist you need 30 years or more of data to find a climate trend?


Are the Models Reliable?
Can we trust Global Climate Models to tell us anything worthwhile?

My View of the Matter
Want to know what I really think about global warming?

Were the 1930s the Warmest Decade?
Were the 1930s warmer? If so, how can there be 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.

No Warming for 15 Years!
Is this frequent denier claim true? Or a statistically illiterate misinterpretation?


Planetary Temperature Calculator
An on-line program to implement the equations and so on from the planetary temperature page. Originally in javascript, this worked on Internet Explorer but failed on Mosiac Firefox and Google Chrome. I have now replaced it with a java applet that works on all three. (Note added 7/13/2009: The algorithm here is from the second version of the temperature page, not the third. I'll update this as soon as I can find the time...)

Saturation
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 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 the Global Warming Deniers are WRONG

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!"

Why Rush Limbaugh is Wrong
"Volcanoes put out more CO2 than all human technology!"

Why Ferenc M. Miskolczi is Wrong
"Earth's gray IR optical thickness is fixed at 1.87!"

Why Viscount Monckton is Wrong
"Temperature leads CO2, not the other way around!"


Why Tilo Reber is Wrong
"El Niño and La Niña don't affect short-term temperature trends!"

Why SAL is Wrong
"The Earth's not warming, new CO2 is from the ocean, it's the sun, Stupid! Svensmark rules, Einstein was a plagiarist, etc., etc."

Why Roy Spencer is Wrong
"The fraction of carbon dioxide in the air is too small to matter!"

Why Vangel Vesovski is Wrong
"The satellites show temperature has been falling since 1998!"
