It's all relative. the 5-8%'ers are morons compared to you. For sure. But then one has to question anyone's intelligence who thinks a 0.04% of CO2 means that it isn't a significant contributor to temperature. Of course you need to talk to someone who understands chemistry and physics. It is all relative.
In your case, you have been bombarded on this forum many times with information such as:
"Carbon dioxide (CO2), despite being present in a small percentage of the Earth's atmosphere, has a significant impact on its warming through the greenhouse effect. Here's a detailed explanation of the process:
- Absorption of Infrared Radiation: CO2 molecules are particularly effective at absorbing infrared radiation, which is the heat energy emitted by the Earth. The Earth absorbs sunlight, which warms its surface, and then radiates this energy back towards space as infrared radiation. While some gases in the atmosphere, like nitrogen and oxygen, are mostly transparent to infrared radiation, CO2 absorbs this energy efficiently.
- Vibrational Modes: The molecular structure of CO2 allows it to vibrate in ways that interact with infrared radiation. These vibrational modes can absorb infrared radiation at specific wavelengths, particularly around 15 micrometers, which is a significant component of Earth's outgoing energy.
- Re-radiation: Once CO2 molecules absorb infrared radiation, they don't hold onto the energy. Instead, they re-radiate it in all directions. This redistribution of energy sends some of the heat back towards the Earth’s surface, effectively trapping the heat in the atmosphere rather than allowing it to escape into space.
- Amplification by Feedbacks: The initial warming caused by CO2 can lead to additional effects that amplify warming. For example, warmer temperatures can cause more water to evaporate, and since water vapor is itself a powerful greenhouse gas, this can lead to further warming—a positive feedback loop.
- Long Atmospheric Lifetime: CO2 has a long lifetime in the atmosphere compared to other greenhouse gases. Once released, it can continue affecting the climate system for hundreds to thousands of years. This prolonged presence magnifies its impact on atmospheric warming.
- Concentration Increase: Over the past century, human activities, particularly the burning of fossil fuels and deforestation, have significantly increased the concentration of CO2 in the atmosphere. This increase from pre-industrial levels of about 280 parts per million (ppm) to over 400 ppm today enhances its greenhouse effect, leading to more substantial warming.
The combined effect of these factors means that even a relatively small increase in CO2 concentration can lead to a disproportionately large increase in warming, making it a critical factor in global climate change." [ChatGPT]
So, what are the origins of your bias? Do you own oil or gas wells?
