Two months ago I was showing my friends a film called “The Great Global Warming Swindle.” As the title suggests, the topic of the movie is the global scale deceit about the man-made global warming. A number of important scientists argue that man has nothing to do with the rise of temperature and everything happens of natural causes.

After a hacker broke into the computers at the University of East Anglia’s Climate Research Unit, stole and published on the internet tens of megabytes of data and emails, it seems that the premises for the greatest scandal in modern science are set, and the truth will be finally revealed. These information show that top scientists have deliberately alter data to exaggerate global warming, destroyed embarrassing data, pushed for discrediting scientists that had other views on the topics, and others. This scandal is now referred to as Climate-gate.

I suggest that you watch the movie. It explains both what is causing the rise in temperature and why all the fuss around this phenomenon.

Now, the theory about man-driver temperature rise is based on two ideas: temperature variations depend on CO2 level variations, and man activity increases the CO2 in the atmosphere. Here are two charts from Wikipedia that show the variation of temperature in the last 150 years and last 1000 years.

You can find more charts here.

What these charts show is that in the last 150 years the temperature has risen and fallen. The greater rise occurred before 1940. And after 1940, when the world entered an economic boom, the temperature dropped for 3 decades. That doesn’t make any sense if the original hypothesis, that the more CO2 the greater the temperature, is true, because booming economies mean more CO2 being produced. In fact, the scientist were alarmed that a new ice age was coming. On April 28, 1975, Newsweek published an article about cooling and the effects on the planet. Here is a quote from the article:

There are ominous signs that the Earth’s weather patterns have begun to change dramatically and that these changes may portend a drastic decline in food production – with serious political implications for just about every nation on Earth. The drop in food output could begin quite soon, perhaps only 10 years from now. The regions destined to feel its impact are the great wheat-producing lands of Canada and the U.S.S.R. in the North, along with a number of marginally self-sufficient tropical areas – parts of India, Pakistan, Bangladesh, Indochina and Indonesia – where the growing season is dependent upon the rains brought by the monsoon.

Then the question is, is there a link between CO2 and temperature? The answer is yes, but it’s mostly the other way around: the temperature is driving the CO2 level, with CO2 lagging 800-1000 years behind the temperature changes. Here are some charts of atmospheric CO2 concentration and temperature in lower atmosphere for the last 400,000 years.

Here are several articles on this topic:

• Comparison of Atmospheric Temperature with CO2 Over The Last 400,000 Years
• Ice Core Studies Prove CO2 Is Not the Powerful Climate Driver Climate Alarmists Make It Out to Be
• CO2 lags temperature – what does it mean?

The rise of temperature causes a rise of atmospheric CO2 because when the ocean warm the solubility of CO2 in the water falls, which leads to more CO2 being released into the atmosphere from the oceans. The amount of CO2 released in the atmosphere by man is much less than the one released from the oceans. Why is there a lag between the rise of temperature and CO2? Because the oceans act as a big buffer, but the exact dynamics are not yet well known. However, this doesn’t mean that the greenhouse effect doesn’t exist. It does. As more CO2 is released into the atmosphere, it absorbs more radiation reflected by the earth surface, heating the atmosphere.

So why is temperature rising? What is driving it? Well, the answer is the sun. The more solar activity, the more solar wind and cosmic dust hit the atmosphere which influences the formation of clouds and eventually the temperature. The next images shows the correlation between solar sunspots and global temperature variations.

You can read more about sunspots observations here:

• Wikipedia: Sunspots
• History of Sunspot Observations
• Solar Sunspot Activity vs. Global Temperature Variations
• Solar Cycle 24 – real time monitoring of the sun activity

Of course, not everybody agrees that Temperature, CO2 & sunspots correlate. For instance, you can read the following article that claims the opposite. It could be possible that this hypothesis is wrong, as many other theories were proved wrong over time.

Hopefully in the coming years (because this will take some time) the truth will be revealed. It would be silly to waste our efforts on the wrong direction. However, whatever the truth is, consuming the planet’s resource on a ever growing pace will prove catastrophic. We will never be able to kill the planet. But the planet can terminate us at any time.
