After making a quick visit to a blog I was introduced to on Twitter, and noticing the incredible number of errors I decided to take just a short segment of it and see how many corrections I could make to the information. This post is the result of examining just two paragraphs a little more closely than I did in my first perusal.
The quotes are taken directly from the blog, and I’ve included a link to it so context can be checked.
“What we don’t know is there might not be any evidence to back it up because much of the evidence has been “adjusted” to support the global warming craze.”
Any adjustments that have been made to temperatures have been made to account for UHI, altitude, where temperatures are affected by the lapse rate, and to remove outliers, whether they are too high or too low. All adjustments have been documented in peer reviewed journals and their functionality reviewed by independent scientists.
“What we do know is that our planet has supported life for thousands of years and we do not have nearly as much positive or negative impact on it as we are led to believe. ”
Life has existed on land for at least 350,000,000 years, and has experienced 21 different mass die outs. Our concern is the ecology as it stands today, and how rapid changes will affect not just the biosphere but human culture. Adaptation takes time, and rapid change can result in conditions even humans can find difficult.
Nobody has ever claimed we have direct control of the climate. What we do have is control over a source of CO2 that has been segregated from the normal carbon cycle for several million years. In complex systems even small changes, if made in the right area, can have large consequences. The world’s most potent poison, Clostridium botulinum, doesn’t kill through volume – it only takes 0.4 billionth of a gram per kilogram of weight to kill – but through which biological system it affects. CO2 does something similar. All radiation from the sun that doesn’t get reflected back to space has its frequency changed to the UV band. CO2 is invisible to almost all radiation but UV. This means that non-UV radiation coming to Earth bypasses CO2 but after that radiation is converted to UV it gets absorbed by CO2 on the way back out to space.
“The key factor of the global warming argument, critically concentrated Carbon Dioxide (CO2) in our atmosphere, is a fallacy because our planet’s ecosystem would actually do better in concentrated CO2 environments.”
This comment is a fallacy. It’s a straw man argument. Ecologies adapt extremely well, but they do so on geological time frames, not human time frames. We’re concerned with the next several hundred years, not the next several thousand years.
Not all plants improve with increased CO2. Aside from that, the biggest problem with this argument is the effect rising temperatures have on climate patterns. For plants to benefit from increased CO2, both ground nitrogen and available H2O have to keep pace with the increased CO2. Without those two other molecules increased CO2 does little to nothing.
“Some greenhouses even use a warming technique to improve the growth rates of their plants.”
The warming is to encourage growth in plants that have evolved in tropical environments. Those same greenhouses frequently add CO2. Those same greenhouses also supply extra water and nitrogen. See above.
“Our oceans help to regulate the atmospheric temperature and keep it balanced. We have nothing to do with this process and research scientists know that.”
The reason the ocean regulates the temperature is because its mass is far greater than that of the atmosphere, it takes far longer to heat up and cool off than the atmosphere or even the land does. However if the oceans do heat up, as they are, then the only regulation they’ll do is to warm the atmosphere even more. The oceans also regulate the amount of CO2 in the atmosphere by absorbing CO2, until it warms up to a point where less CO2 is being absorbed than being released.
The Earth’s carbon balance has varied by no more than a couple of dozen ppmv from the mean of 280 ppmv for more than 50 million years. By releasing carbon that has been sequestered from the atmosphere since at least that time, we’ve boosted the atmospheric concentration to 400 ppmv
