Global Temperature Trends Since 2500 B.C. — This stuff keeps coming in and nobody wants to hear it.
From the late 1940s through the early 1970s, a climate research organization called the Weather Science Foundation of Crystal Lake, Illinois, determined that the planet’s warm, cold, wet and dry periods were the result of alternating short-term and long-term climatic cycles. These researchers and scientists also concluded that the Earth’s ever-changing climate likewise has influenced global and regional economies, human and animal migrations, science, religion and the arts as well as shifting forms of government and strength of leadership.Much of this data was based upon thousands of hours of research done by Dr. Raymond H. Wheeler and his associates during the 1930s and 1940s at the University of Kansas. Dr. Wheeler was well-known for his discovery of various climate cycles, including his highly-regarded ‘510-Year Drought Clock’ that he detailed at the end of the ‘Dust Bowl’ era in the late 1930s.During the early 1970s, our planet was in the midst of a colder and drier weather cycle. Inflationary recessions and oil shortages led to rationing and long gas lines at service stations worldwide. The situation at that time was far worse than it is now, at least for the time being.

RGB… a big THANK YOU for #125.

No, it’s not.
The actual temperature is only shown in three instances: the years 1607, 1998, and “zero” on the y-axis which is labeled “normal temperature” (whatever that is).
Do these labels which you and no-one else can see show the temperature reached in 1100 BC during the “Hebrew Exodus from Egypt”?
Do these labels which you and no-one else can see show the temperature reached in 1700 BC in the middle of “Nomanic Time – Era of Great Migration” (whatever that is)?
Can you tell me the temperature shown in ANY other point in the graph other than the three points I listed?
Also, it’s worth noting that the “Viking Explorations (reached NE Canada)” is off by 300 years – should be 1000 AD, not 1300 AD. They were long gone from the seas by then.
The graph claims that “when volcanic activity has increased, global temperatures suddenly plummet, often within weeks or months.”
The graph lists 22 major eruptions, yet 11 of these are on the period of sharpest and most prolonged increase in temperature, and 4 of the remaining 11 also occur during periods of increasing temperature. And the 1991 eruption of Mount Pinatubo is the only eruption out of the 11 listed that correlates with a change from increasing temperature to decreasing temperature.

I offer to you, though I do not expect you to accept, my sincere apologies. I read Y axis and saw X axis. Perhaps because I was already condemning the authors for making such a busy chart.
ScotterOtter, if you’re still reading this thread, the apology really is for you.
Apology accepted, sorry for my snideness.
#125, RBG,
A good post.
From the link,
Who is claiming MAN is the only emitter of CO2? Not one I know of.
Who is claiming the earth hasn’t gone through natural cycles of warmth and cold. Not one I know of.
Again I make the point that no denier takes into account. It took tens of millions of years to sequester all the carbon in coal, oil, and natural gas. We are releasing that as CO2 into the atmosphere over a few decades.
As your link points out, CO2 is a greenhouse gas. As no one here noticed, so much of the tropical rain forests, that acted as the major CO2 absorption sink, have been destroyed.
From your link,
You do the math about how much time we have.
# 132 Les — Finaly, why are the ice caps on Mars receeding? SUVs?
You’re silly, Les. The reason the Martian ice caps are receding is because all the polar bears died and they weren’t needed anymore.
3 pointer from full court for John Carter
ROFL
Vesuvius eruption date of 1741 is wrong: the second big eruption was in 1631; the first in is 79 AD and destroyed 3 big cities, covering with ash. Now you can visit those cities, parfectly maintained by ash.
Can I simply say what a reduction to seek out somebody who really is aware of what theyre speaking about on the internet. You positively know how to convey a problem to light and make it important. Extra folks need to learn this and understand this aspect of the story. I cant imagine youre no more fashionable since you definitely have the gift.
Thanks much! Subscribed via rss.
None of this takes into account the Milankovitch Cycles of roughly 21ky, 41ky and 413ky periods. These are astronomical curves which combine to amplify or reduce the impact of the Earth’s relativity to the Sun, causing variation in climate. Most interesting of the graphs above is the 400,000 chart showing the four major spikes in temperature,m followed quickly by sudden cold periods which lasted for some extended time. (see Les’ contribution, Figure 1-5, which doesn’t show it, but coincides with Foraminifera samples from the deep ocean sediments.) Vostok Ice and the forams are almost congruent.
Milankovitch seems to indicate that we are heading into a 30,000 year cycle of warming. ON TOP OF THAT, add the increasing impact of human production of CO2, which traps hothouse insolation, yatta, yatta . . . Humans are amplifying the global warming occurring naturally.
