This first graph looks bad, doesn't it -- steeper upward temperature trend. Horizontal red line is temperature at 1950.

Figure 1-1 Global warming
The second graph shows today's temperature isn't out of the norm. Horizontal blue line is temperature at 1950.

Figure 1-2 Climate of the last 2400 years
The next graph shows a downtrend in temperatures from 8,000 years ago to today. The down trend is steeper in the recent 2,000 years. From left to right the upper spikes have lower highs while the lower spikes have lower lows. (The same effect can be seen in Figure 1-2, above.)

Figure 1-3 Climate of the last 12,000 years
This graph shows that agriculture and stationary societies emerged 8,000 years ago during a time frame when global temperature was much higher than normal, or average.

Figure 1-4 Climate of the last 100,000 years
The next graph shows that the recent 8,000 years was one of five brief hot spikes when glaciers were at minimums. With much longer troughs when glacials (ice ages) were the norm most of the time.

The graph below is reversed. That is, the left side is present day and the right side is 3 million years ago. It shows a 3 million year down trend toward widening extremes in the temperature cycle.

Figure 1-6 Climate for the last 3 million years
The final graph shows CO2 lagging temperature change -- not leading it.

More than 20 years ago, former Colorado Senator and Deputy Undersecretary of State Tim Wirth, who presently heads the UN Foundation said:
"What we've got to do in energy conservation is try to ride the global warming issue," said Sen. Timothy E. Wirth, D-Colo., the Energy and Natural Resources Committee's point man on that issue and chairman of the Alliance to Save Energy. "Even if the theory of global warming is wrong, to have approached global warming as if it is real means energy conservation, so we will be doing the right thing anyway in terms of economic policy and environmental policy."

Climatologist Dr. Steven Schneider is a professor at Stanford University and a member of the National Center for Atmospheric Research. He has recently criticized Danish Statistician Dr. Bjorn Lomborg for scientific dishonesty in Lomborg's book "The Skeptical Environmentalist".
But Schneider is hardly a paragon of scientific integrity. In a now famous interview in the October 1989 issue of Discover magazine, Schneider stated:
On the one hand, as scientists we are ethically bound to the scientific method, in effect promising to tell the truth, the whole truth, and nothing but - which means that we must include all the doubts, the caveats, the ifs, ands and buts.On the other hand, we are not just scientists but human beings as well. And like most people, we'd like to see the world a better place, which in this context translates into our working to reduce the risk of potentially disastrous climate change.
To do that, we need to get some broad-based support, to capture the public's imagination. That, of course, entails getting loads of media coverage. So we have to offer up scary scenarios, make simplified, dramatic statements, and make little mention of any doubts we might have. Each of us has to decide what the right balance is between being effective and being honest.
"A senior U.N. environmental official says entire nations could be wiped off the face of the Earth by rising sea levels if the global warming trend is not reversed by the year 2000. Coastal flooding and crop failures would create an exodus of 'eco-refugees,' threatening political chaos, said Noel Brown, director of the New York office of the United Nations U.N. Environment Program, or UNEP. He said governments have a 10-year window of opportunity to solve the [problem]." This was published in the Miami Herald on the 5th of July, 1989.

CO2 Accounting Error in US House Cap and Trade Bill Creates Perverse Incentives to Clear Forests
Several recent studies estimate that this error, applied globally,
would create strong incentives to clear land as carbon caps tighten.
One study estimated that a global CO2 target of 450 ppm under this
accounting would cause bioenergy crops to expand to displace virtually
all the world's natural forests and savannahs by 2065, releasing up to
37 gigatons (Gt) of CO2 per year (comparable to total human CO2
emissions today). Another study predicts that, based solely on economic
considerations, bioenergy could displace 59% of the world's natural
forest cover and release an additional 9 Gt of CO2 per year to achieve
a 50% "cut" in greenhouse gases by 2050.

CO2 Emissions May Prevent Projected Ice Age: Discovery News
Two researchers built a high-powered computer model to take a closer look at these intriguing phases of cooling and warmth. Earth has experienced long periods of extreme cold over the billions of years of its history. The big freezes are interspersed with "interglacial" periods of relative warmth, of the kind we have experienced since the end of the last Ice Age, around 11,000 years ago.
These climate swings have natural causes, believed to be rooted
particularly in changes in Earth's orbit and axis that, while minute,
have a powerful effect on how much solar heat falls on the planet.

Does CO2 really drive global warming?
More from Dr. Essenhigh
Compared to man-made sources' emission of about 5 to 6 billion tons per year, the natural sources would then account for more than 95 percent of all atmospheric carbon dioxide, Essenhigh said.
"At 6 billion tons, humans are then responsible for a comparatively small amount - less than 5 percent - of atmospheric carbon dioxide," he said. "And if nature is the source of the rest of the carbon dioxide, then it is difficult to see that man-made carbon dioxide can be driving the rising temperatures.
