I don’t know if we’ll ever put the global warming/climate change/extreme blah blah argument to rest. Unfortunately, far too many people are arguing on the side of funding rather than the side of science.
The graphic below, however, reveals something rather startling. It is a composite of two different graphs. Please click on it to see a full-sized version.
The first graph in the upper left shows the AGT (average global temperature) between the present and 2.4 mya (million years ago). As you can see, prior to about 30 mya, Earth was far warmer than it is today. In fact, normal temperatures remained above 70 deg F, while ice age temperatures dipped to around 50 deg F.
Given the age, however, the data was not very fine-grained, meaning that ice-age temperatures could easily have dipped down to what they have been over the last 0.5 mya (500 thousand years), ranging between 20 deg F and roughly 35 deg F.
The graph in the upper left is roughly a thousand times greater scale than the other two graphs. The red lines from the bottom graph show just how much smaller the more recent 450 thousand years in the other two graphs than the long-term, 2.4 billion year graph in the upper left.
Now here’s the interesting part: The graph on the right is properly positioned with respect to temperature. Notice the 50 deg F point on both graphs match. Thus, when the 2.4 by graph says “Ice Age” at its right, and given the glacial and interglacial temperatures on the 450,000 year graph to the right, here’s what it means:
Earth is STILL in the middle of its last ice age, some 40 deg F COLDER than the periods between ice ages.
Furthermore, current interglacial temperatures are a good 9 deg F colder than they usually are, meaning another 9 deg F increase would be entirely normal given the glacial and interglacial periods over the last half a million years, during which time both Earth and mankind has survived just fine.
By comparison, the IPCC’s “worst case” analysis and conclusion that global temperatures might exceed 6 deg F by the year 2100 is entirely within the range of “normal temperature variation,” clearly evidenced by the AGT over the last half-million years. With respect to Earth’s “normal” temperature over the last 1 billion years, however, what little global warming we might have experienced is but a tiny drop in the bucket as to 40 deg F warming trend good, old Mother Earth will toss our way if she decides to thaw us out back to Earth REAL normal temperature.
Naturally, since all climatologists already know (or should know) this information, it royally begs the question as to why they keep whining about the few puny degrees that mankind “might” add to the planet’s temperature over the next couple hundred years. Is it money? Billions of dollars in government funding can certainly provide a huge incentive for telling whoppers to the American taxpayers who fund the vast majority of those grants. Perhaps it’s a pseudo-religious belief that they’re doing something “good” for mankind, and the belief is so strong as to blind them to the truth.
Regardless, the truth remains, as clearly evidenced by Earth’s climate history:
A. As compared to Earth’s pattern of temperatures throughout it’s determinable history, we’re currently in the middle of an ice age, albeit in a relatively minor interglacial peak.
B. Temperatures could easily drop 10 deg F at any time, plunging the Earth into the deeper portion of an ice age such as the ones that carved Yosemite with deep glaciars.
C. Temperatures could also easily rise 40 or more deg F at any time, turning Greenland, Siberia, and the Yukon into the next series of tropical jungles, while turning the Congo and Amazon River basin into the next Sahara.
D. All of these possibilities are normal and natural, completely void of any human input. They have happened here on Earth multiple times in the past, completely without any input or causative factors by mankind.
E. No matter what mankind does, it won’t stop the normal, natural, and inevitable swings in Earth’s temperature. Mankind’s attempts to stop these swings is a reflection of arrogance at best, but at worst, a widespread attempt to extort (if not outright steal) vast sums of money from the hard-working people of this world.
In summary, I would like to divert your attention to this article from Investor’s Business Daily:
New Phrase for the Day: Global Warming Derangement Syndrome – When the Media and other Non-Experts claim those who don’t agree with their misconceptions — particularly politicians — are “deranged.”
“It’s the media and alarmists’ distance from reality that has moved. How else to explain how the alarmists, with a supportive media, could rip Trump for backing out of a deal they said was insufficient to start with?”
“The alarmists’ screeching is incessant, their lectures grating and without restraint, their hypocrisy as fetid as the wrong side of a sewage treatment plant. And of course their fanaticism is so rigid they cannot acknowledge anything that challenges their narrative.”
