At one point the atmosphere contained no oxygen. Can we extrapolate a greater point from that fact? No, because the planet has undergone severe changes throughout it's history. We humans have been polluting for just a tiny fraction of that history. Therefore, and I hope this gets past your conceptual barriers--we need to look at the data from the past one hundred years or so, when industrial society became dominant.
Is this a difficult concept?
The human contribution of CO2 is negligible.
CO2 is NOT catastrophic either.
5). Current Global Warming trends are neither catastrophic nor are they unusual given the Earth’s very recent past.
Global Warming Alarmists state that man made CO2 is responsible for what is becoming a catastrophic increase in Global temperatures. (You know the 1 degree increase in the last century).
Science has told us for decades (decades prior to the Global Warming Alarmist taking the stage) that earth’s last ice age (referred to as the “little ice age”) began sometime near the year 1400 and lasted until approximately 1860. This “little ice age” was responsible for disasters like the “Irish Potato Famine”. The end of the “little ice age” was not preceeded by an increase in CO2 levels. Other natural causes were responsible for the “global warming” which followed the end of the “little ice age” and continues to this date. http://www.geocraft.com/WVFossils/ice_ages.html , http://www.friendsofscience.org/assets/ ... tml#Hockey
During the Middle Ages (1066 – 1485) a time that saw the Norman’s conquest of England, King Richard The Lion Hearted, The Crusades – all 7 of them, the Early Italian Renaissance - a period of time long before the ”Industrial Revolution”, mankind contributed very little to Global CO2 levels. The Middle Ages experienced a period of global warming that exceeds the global warming of today. Yes, temperatures were higher than they are now, significantly higher. http://www.friendsofscience.org/assets/ ... tml#Hockey , http://www.theage.com.au/articles/2003/ ... 63628.html ,
“A review of more than 240 scientific studies has shown that today’s temperatures are neither the “warmest ever” nor are the Temperatures producing extreme conditions “never seen before”. The findings of these 240 studies stand in stark contrast to the claims of the alarmists. The findings prove that the world had a medieval warm period between the ninth and 14th centuries, with world temperatures significantly higher than today’s. They also confirm claims that a little Ice Age began in about 1300, with the world cooling dramatically. Just before the turn of the century, in 1900, the world began to warm up, but as of today, has still to reach the balmy temperatures of the Middle Ages. The end of the little Ice Age is significant because it implies that the records used by climate scientists (THE ALARMISTS) date from when the Earth was relatively cold, thereby exaggerating the significance of today’s temperature rise. According to the researchers, the evidence confirms suspicions that today’s alleged “unprecedented” temperatures are simply the result of examining temperature change over too short a period. http://www.theage.com.au/articles/2003/ ... 63628.html
The Global Warming Alarmists have choosen the “Little Ice Age” to begin their temperature measurements and comparisons. By choosing the coldest period in Earth’s history over the last 10,000 years, the Alarmists are assured of finding data that will show a warming trend. But the warming trend is not unusual when compared to all of Earth’s prior warming trends.
Philip Stott, emeritus professor of bio-geography at the University of London, said: “What has been forgotten in all the discussion about global warming is a proper sense of history.” http://www.theage.com.au/articles/2003/ ... 63628.html , http://www.michaelkeller.com/news/news575.htm , http://www.stanford.edu/~moore/history_health.html , http://www.freerepublic.com/focus/f-news/886494/posts , http://www.climateaudit.org/?p=2514
If mankind were to cease all economic production and cease buring all carbon fuels, at best, a 2% reduction in CO2 levels could be had. Additional reductions from manking would need to involve an end to “respiration” – manking would need to stop breathing. Having achieved these miniscule reductions, at fantastic cost and loss of personal freedom, nature could, in the bat of an eye, dramatically reverse any man made reduction. You see, temperature drives the CO2 level, CO2 levels do not drive temperature.

Recent studies call into question wether Global Warming is continuing - the studies refute the wild claims concerning the amount of ”warming” that occurred in the 1990′s. Even the ultra-green “Discovery Channel” has noted studies which indicate “global warming” is on “hold” and may not reappear for decades. That “Global Temperatures have flatlined since 2001″. http://www.msnbc.msn.com/id/29469287/
The Boston Globe has asked, “Where is the Global Warming?”, before noting, “But for many people, the science of climate change is not nearly as important as the religion of climate change. When Al Gore insisted yet again at a conference last Thursday that there can be no debate about global warming, he was speaking not with the authority of a man of science, but with the closed-minded dogmatism of a religious zealot. Dogma and zealotry have their virtues, no doubt. But if we want to understand where global warming has gone, those aren’t the tools we need.” http://www.boston.com/bostonglobe/edito ... l_warming/
