The climate is changing, and it has been changing for a very long time. In fact, the climate has always been changing, and there are a myriad of factors that influence climate change like solar activity and much more.
If you’re not educated on climate science, it’s easy to adopt the “doomsday” perspective that’s often dished out by mainstream media. However, when you look at what actual climate scientists are saying, it doesn’t seem like anyone on either side agrees with the media’s “climate hysteria” narrative.
The main argument among those who ascribe to the hysteria perspective is that CO2 levels are the highest they’ve ever been since we started to record them, currently sitting at approximately 415 parts per million (ppm).
It’s not like climate scientists disagree on the idea that CO2 causes some warming of our atmosphere, that seems to be a fact that’s firmly established in scientific literature. But what’s never mentioned is the fact that CO2 levels have been significantly higher than what they are now; in fact, CO2 levels have been in thousands ppm and Earth’s temperature has been much warmer than it is now.
The idea that human CO2 emissions are responsible for shifts and changes in the climate is not scientifically valid, yet policy initiatives that do nothing for our environment are being produced and put forward, putting large sums of money in the pockets of some very powerful people.
“Our crop plants evolved about 400 million years ago, when CO2 in the atmosphere was about 5000 parts per million! Our evergreen trees and shrubs evolved about 360 million years ago, with CO2 levels at about 4,000 ppm. When our deciduous trees evolved about 160 million years ago, the CO2 level was about 2,200 ppm – still five times the current level.” – Dennis T. Avery, agricultural and environmental economist, senior fellow for the Center for Global Food Issues in Virginia, and formerly a senior analyst for the U.S. Department of State (source)
CO2 causing a temperature increase is the backbone of the global warming argument, but does CO2 even cause the temperature to increase, or does an increase in temperature cause a rise in C02?
“The question is how does the Intergovernmental Panel on Climate Change (IPCC) determine that an increase in atmospheric CO2 causes an increase in global temperature? The answer is they assumed it was the case and confirmed it by increasing CO2 levels in their computer climate models and the temperature went up.
Science must overlook the fact that they wrote the computer code that told the computer to increase temperature with a CO2 increase. Science must ask if that sequence is confirmed by empirical evidence? Some scientists did that and found the empirical evidence showed it was not true.
Why isn’t this central to all debate about anthropogenic global warming?” – Dr. Tim Ball, (source) former professor in the Department of Geography at the University of Winnipeg
William Happer, American physicist and the Cyrus Fogg Brackett Professor of Physics, Emeritus, at Princeton University, is one of what seems to be thousands of academics to go unheard by the mainstream media who shares the same perspective:
In every careful study, the temperature first rises and then CO2 rises, and the temperature first falls and then CO2 falls, temperature is causing changes of CO2 at least for the last million years, there’s no question about that. (source)
He also pointed out the major ice ages in Earth’s past when C02 levels were also extremely high, much higher than they are now, and did so to show how the correlation between C02 and temperature is “not all that good.”
In their paper on the Vostok Ice Core, Petit et al (1999), they show how CO2 lags temperature during the onset of glaciations by several thousands of years, but offer no explanation. They also observe that CH4 and CO2 are not perfectly aligned with each other, but offer no explanation.
The significance is that temperature may influence C02 amounts. At the onset of glaciations, temperature drops to glacial values before CO2 begins to fall, suggesting that CO2 has little influence on temperature modulation at these times as well.
