Glenn Beck
-
Rebuttal to Glenn Beck on Global Warming: A common problem with media personalities is actually multifaceted. They tend to market to their base and they tend to not understand the science and confuse the issue. This results in a battle of science vs. rhetoric. Glenn Beck is an excellent example and exhibits the problem well. Unfortunately, in the media, he is not alone.

Keeling Curves
-
Most understand the Keeling curve as an upward trend of CO2 in the atmosphere as measured by the Mauna Loa measurements of Charles David Keeling. But there are two Keeling curves and they are related to each other in more than one way. While CO2 increases, it stands to reason that O2 will decrease (C + O2 = CO2). The two curves also have family ties.

The Denial Machine
-
"The Denial Machine" was produced in 2006 but the denial machine behind the efforts to confuse the issue of human caused global warming started long before that. It's seeds were planted as far back as 1957 when Dr. Roger Revelle from Scripps Institute of Oceanography produced substantial work showing the implications and increased CO2 in the atmosphere. As the 'Keeling Curve' went up, the denial machine grew larger and more manipulative, and still continues today.

Greenland Ice Melt
-
The ice is melting in Greenland. The ice melt rate is also accelerating. What does this mean? That depends on your context in time, your geographic location, and ultimately, why it is happening?

The Great Global Warming Swindle
-
The Martin Durkin Film, 'The Great Global Warming Swindle', made so many mistakes that after the film was released, the filmmaker was forced to reedit the film. In that process, he removed some of the most blatant mistakes that he had made, but left in some other claims that were also entirely wrong.

Henrik Svensmark
-
Rebuttal to Svensmark assertions: Svensmark has received a fair amount of attention in the denialist world. But why? He says he is being ignored. But Why? Is it because there is a great conspiracy of scientists trying to hide the truth about galactic cosmic rays? Or is that that Svensmarks conclusions were not supported by the work presented? As it turns out, his conclusions were not sufficiently supported.

Myths vs. Facts: Global Warming
-
It's the Sun!
-
This is a common myth. It sounds sort of logical if you don't understand the contexts involved. The fact is that we receive most of our heat energy from the sun and a little bit from the heat stored in the earths core. But does that mean this global warming event is caused by the sun? No. Here's why:

CO2 is Plant Food
-
Another interesting myth because it sounds logical that if CO2 is good for plants, more CO2 must be better. Some scientists have already begun to look at this assumption. Initial examinations indicate that more might not be better when it comes to food and nutritive quality. The US department of agriculture and interested scientists will likely be looking more deeply at this question.

Myths vs. Facts: Global Warming
-
Global Warming is Only Part Human Caused
-
This is an interesting myth because it is very ambiguous. Which part? What percentage? How much warming is human caused v. natural cycle? The problem is it's part true, and part not true, so context is needed. One needs to understand the difference between natural variation and the new path that the climate is on.

Atmospheric Aerosols
-
Aerosols are tiny particles that are capable of suspending in the atmosphere. Most come from natural means such as dust storms, volcanoes, fires, or even vegetation and sea spray (sea salt released into the atmosphere). Human activity also contributes aerosol pollution through the alteration of natural surface cover, industrial pollutants, and the burning of fossil fuels.
