Imagine you’re sitting in Starbucks holding an iPad, iPhone or iPod and someone walks up to you and says, “that thing in your hand does not exist”. You’d look at them, think they were off their rocker and quickly scurry away. When climate-deniers tell me increased levels of CO2 are not responsible for global warming, I believe they are either brainwashed (followship syndrome), have a political agenda so truth doesn’t matter or they’re just plain crazy.
You may be scratching your head and asking why I’m drawing parallels between Apple products and manmade climate change but the answer is simple. The same technology used to predict how CO2 impacts temperature change is also used in the manufacture of the advanced computer chips (integrated circuits) that go into cell phones, iPhones and all similar devices including computers. However there is one big difference, predicting CO2 related climate change is magnitudes simpler than controlling the manufacturing of integrated circuits.
Computer chips, which are about the size of a finger nail, have millions of components inside them (called gates or transistors) with dimensions smaller than 100 nanometers. For comparison sake, the width of a human hair is about 100,000 nanometers. These chip components are so small they cannot be seen through the lenses of the most advance optical microscopes and aren’t clearly visible with multi-million dollar scanning electron microscopes. The shape and dimensions of these super small parts can only be “inferred” or predicted by analyzing how light (similar to sunlight) reflects, absorbs and scatters off the parts. A special machine shines light onto the part and then captures the light coming off them. The light-data creates a “kind of” fingerprint that resembles an up and down squiggly line. The light-fingerprint is compared to millions upon millions of stored fingerprints, which were created by computer simulations, until a match is made. Once a match is detected, the shape and dimensions are provided.
Climatologist use the same technique as described above except the problem is much simpler. The sun is the source of light that is analyzed as it reflects, absorbs and scatters through and off the atmosphere as well as the Earth’s surface. Computer chips are more complex because they have forty or more material layers or atmospheres with varying chemistry while the Earth has just one atmosphere with a few elements such as oxygen, CO2, nitrogen and so on. The dimension that climatologist look for is temperature as it relates to CO2 concentration. Computer simulations are used to predict or “infer” temperature change as the chemistry of our atmosphere varies; computer simulations predict a rise in temperature as CO2 amounts go up. CO2 concentrations have increased from 175 ppm (parts per million) to 395 ppm since the start of the industrial revolution. This is the fastest increase in Earth’s history and we know this from another type of scientific analysis but I’ll save that explanation for another day.
If you believe iPhones, high-speed internet and similar products exist, you must also believe in manmade global warming because the computer simulations that allow the manufacture of these gadgets also predict an increase in temperature as CO2 concentrations rise.
You can’t believe in one and not the other, it’s illogical.
