What caused the series of more than 20 ice ages that have come and gone during the past 2 million years of Earth history?

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.

The final graph shows CO2 lagging temperature change -- not leading it.

Quotes from a Scientist and a Politician

What a Politican Says

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."

What a Scientist Says

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.

20 Years Ago

"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.

Climatologists Baffled by Global Warming Time-Out

Global warming appears to have stalled. Climatologists are puzzled as to why average global temperatures have stopped rising over the last 10 years. Some attribute the trend to a lack of sunspots, while others explain it through ocean currents.

Terrestrial ecosystems and the oceans have a much greater capacity to absorb CO2 than had been previously expected

New data published in the journal Geophysical Research Letters show that the balance between the airborne and the absorbed fraction of carbon dioxide has stayed approximately constant since 1850, despite emissions of carbon dioxide having risen from about 2 billion tons a year in 1850 to 35 billion tons a year now

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.

Crops under stress as temperatures fall

For the second time in little over a year, it looks as though the world may be heading for a serious food crisis, thanks to our old friend "climate change". June brought heavy snowfall across large parts of western Canada and the northern states of the American Midwest. In Manitoba last week, it was -4C. North Dakota had its first June snow for 60 years.There was midsummer snow not just in Norway and the Cairngorms, but even in Saudi Arabia.

“Re-framing” the global warming debate: Cooler Weather Heats up Debate

According to the theory of global warming being touted by the United Nations Intergovernmental Panel on Climate Change (IPCC), Al Gore and many others (who have spent an estimated $50 billion trying to show man-made greenhouse gas emissions are causing catastrophic global warming) the earth’s temperatures should be rising in line with a continuing increase in carbon dioxide emissions.[3] The problem is that the planet stopped warming more than a decade ago.

UN Blowback: More Than 650 International Scientists Dissent Over Man-Made Global Warming Claims

The over 650 dissenting scientists are more than 12 times the number of UN scientists (52) who authored the media-hyped IPCC 2007 Summary for Policymakers.

This new report issued by the Senate Environment and Public Works Committee is the latest evidence of the growing groundswell of scientific opposition challenging significant aspects of the claims of the UN IPCC and Al Gore. Scientific meetings are now being dominated by a growing number of skeptical scientists.

Earth on the Brink of an Ice Age

The Vostok ice core data graph reveals that global CO2 levels regularly rose and fell in a direct response to the natural cycle of Ice Age minimums and maximums during the past four hundred and twenty thousand years. Within that natural cycle, about every 110,000 years global temperatures, followed by global CO2 levels, have peaked at approximately the same levels which they are at today.

The world has never seen such freezing heat

A surreal scientific blunder last week raised a huge question mark about the temperature records that underpin the worldwide alarm over global warming. On Monday, Nasa's Goddard Institute for Space Studies (GISS), which is run by Al Gore's chief scientific ally, Dr James Hansen, and is one of four bodies responsible for monitoring global temperatures, announced that last month was the hottest October on record.
The problem was that it wasn't true.

EU carbon trading system brings windfalls for some, with little benefit to climate

The European Union started with the most high-minded of ecological goals: to create a market that would encourage companies to reduce greenhouse gases by making them pay for each ton emitted into the atmosphere.

Four years later, the carbon trading system has created a multibillion-euro windfall for some of the continent's biggest polluters, with little or no noticeable benefit to the environment so far.

CO2 Emissions May Prevent Projected Ice Age: Discovery News

Scheduled shifts in Earth's orbit should plunge the planet into an enduring Ice Age thousands of years from now but the event will probably be averted because of man-made greenhouse gases, scientists said Wednesday

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.

Climate Sensitivity Reconsidered

The Intergovernmental Panel on Climate Change (IPCC, 2007) concluded that anthropogenic CO2 emissions probably caused more than half of the "global warming" of the past 50 years and would cause further rapid warming. However, global mean surface temperature has not risen since 1998 and may have fallen since late 2001.

Does CO2 really drive global warming?

More from Dr. Essenhigh

The major greenhouse gas in the atmosphere is water, not CO2, and although CO2 is the only other significant atmospheric absorbing gas, it is still only a minor contributor because of its relatively low concentration.

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.
