Global warming caused by greenhouse gases delays natural patterns of glaciation
January 8, 2012 by Donna Hesterman
Unprecedented levels of greenhouse gases in the Earth's atmosphere are disrupting normal patterns of glaciation, according to a study co-authored by a University of Florida researcher and published online Jan. 8 in Nature Geoscience.
The Earth's current warm period that began about 11,000 years ago should give way to another ice age within about 1,500 years, according to accepted astronomical models. However, current levels of carbon dioxide are trapping too much heat in the atmosphere to allow the Earth to cool as it has in its prehistoric past in response to changes in Earth's orbital pattern. The research team, a collaboration among University College London, University of Cambridge and UF, said their data indicate that the next ice age will likely be delayed by tens of thousands of years.
That may sound like good news, but it probably isn't, said Jim Channell, distinguished professor of geology at UF and co-author.
"Ice sheets like those in western Antarctica are already destabilized by global warming," said Channell. "When they eventually slough off and become a part of the ocean's volume, it will have a dramatic effect on sea level." Ice sheets will continue to melt until the next phase of cooling begins in earnest.
The study looks at the prehistoric climate-change drivers of the past to project the onset of the next ice age. Using astronomical models that show Earth's orbital pattern with all of its fluctuations and wobbles over the last several million years, astronomers can calculate the amount of solar heat that has reached the Earth's atmosphere during past glacial and interglacial periods.
"We know from past records that Earth's orbital characteristics during our present interglacial period are a dead ringer for orbital characteristics in an interglacial period 780,000 years ago," said Channell. The pattern suggests that our current period of warmth should be ending within about 1,500 years.
However, there is a much higher concentration of greenhouse gases trapping the sun's heat in the Earth's atmosphere now than there was in at least the last several million years, he said. So the cooling that would naturally occur due to changes in the Earth's orbital characteristics are unable to turn the temperature tide.
Over the past million years, the Earth's carbon dioxide levels, as recorded in ice core samples, have never reached more than 280 parts per million in the atmosphere. "We are now at 390 parts per million," Channell said. The sudden spike has occurred in the last 150 years.
For millions of years, carbon dioxide levels have ebbed and flowed between ice ages. Orbital patterns initiate periods of warming that cause ocean circulation to change. The changes cause carbon dioxide-rich water in the deep ocean to well up toward the surface where the carbon dioxide is released as a gas back into the atmosphere. The increase in atmospheric carbon dioxide then drives further warming and eventually the orbital pattern shifts again and decreases the amount of solar heat that reaches the Earth.
"The problem is that now we have added to the total amount of CO2 cycling through the system by burning fossil fuels," said Channell. "The cooling forces can't keep up."
Channell said that the study, funded by the National Science Foundation in the U.S, and the Research Council of Norway and the Natural Environment Research Council in the United Kingdom, brings to the forefront the importance of atmospheric carbon dioxide because it shows the dramatic effect that it is having on a natural cycle that has controlled our Earth's climate for millions of years.
"We haven't seen this high concentration of greenhouse gases in the atmosphere for several million years," Channell said. "All bets are off."

While releasing enough CO2 to prevent an ice age would be very reasonable geoengineering, we appear to have ALREADY released more CO2 than is necessary for at least a few hundred years.
If the earth were to start cooling in spite of current CO2 levels, adding methane would be better than CO2 since it would disappear faster than CO2 when the climate swung toward warm again.
Perhaps in a few decades we will understand our climate well enough to manage it.

@Shootist - the ice in Greenland is currently retreating. Even if the climate stayed at its current temperature, the ice would continue receding for some time. And even if we did not further raise the CO2 level, the earth would continue warming for some time (the oceans take a long time to reach equilibrium). Whether under constant temperature or constant CO2 ice would recede further than during the medieval warm period is not known, but grazing in Greenland is not proof the the climate was warmer then. The best temperature proxies say ~1C warmer then, the best climate projections say we'll exceed that within 50 years.

Only when they go down is it weather. A physicist tells us that temperatures are going up, so therefore it is climate by definition.
Are we clear on this? Increasing temperatures are climate. Decreasing temperatures are weather. Any change in the increase in temperature is therefore Climate Change.
Any change in the decrease in temperatures is Climate Disruption it is a disruption in climate change.
To summarize:
increase T = climate
decrease T = weather
delta increase T = climate change
delta decrease T = climate disruption.

The sun is a main-sequence star, and these slowly get hotter as they age.
If we could move the earth 25 meters per year further from the sun, we'd balance the effect of the aging of the sun.
If we could move the earth a few tens of millions of kilometers further from the sun, we could dig up all that buried carbon and return it to the ecosystem.
The problem is that we are digging up the carbon WITHOUT counterbalancing the aging of the sun. This is no problem for the earth, which has seen far bigger changes. It is a problem for our civilization since that is adapted to current conditions.

I am far closer to a libertarian than to a socialist.
But regardless of my politics, humans are adding CO2 to the air, and my politics don't change the absorption spectrum of CO2.
The effect of my politics is that I think that the best way to address this is to calculate the external cost of excess CO2 emissions and apply that cost to CO2 emissions, and use the proceeds to sequester the excess CO2. I would prefer the free market to do this because it is more efficient.
However energy is currently far from being a free market that includes external costs. Unfortunately it will probably take the threat of governments stepping in to get the free market to fix the problem (just as it did with CFCs and the ozone layer).

No, it is socialism that enables the greed of a few to seize state power and grant favors to their friends.
In a free market, millions of individuals make millions of decisions they perceive that are in their self-interest.
If the govt truly protects everyone's property rights, then you can use stop anyone from polluting your air and your water.
But that becomes too difficult for statists and those that pollute collude with the state to allow pollution without compensation.
This enabled the pollution of the Cuyahoga river and its infamous fires. After all, the city needed the tax revenues from the businesses polluting the river. Same for Love Canal. The city wanted the tax revenue so it built houses over a toxic waste dump. This is the fault of the GOVT, not the waste producer.

Here is how markets do it:
"markets are actually very effective at allocating resources and in insuring sustainability--provided that those resources are marketed. "
"markets also give investors an incentive to look at the long term. If they invest in a factory and then let the factory deteriorate, they won't get much for it if they decide to sell it."
"Which is more short sighted: markets or government? The average elected official has a time horizon of two to four--or at most six--years. A typical market-driven company may have a time horizon in decades. That may not seem long to ecologists, but it is far better than a two-year horizon."
"If you want to protect a resource through coercion, the likely result will be violence and generations of resentment against that resource."
{Coercion is the only way socialists know.}

The DIRECT effect of CO2 has been known for over 100 years, and can be demonstrated in a college physics lab.
What is not known are the INDIRECT effects of that warming on water vapor and clouds. Current climate models indicate that the effects of CO2 are amplified several times by the warmth from CO2 increasing water vapor, but the exact amount is unknown and the effects of clouds are an even bigger unknown.
Also known is the gradual hundreds-of-millions-of-years increase in the temperature of the sun and the ~0.1% variability in the solar constant over the last few decades. What is NOT known is the variability over hundreds of years to millions of years, although C14 data put a few-percent limit on it.

How can this model represent an emergent system? It can't.
Bottom line is CO2 is an easy gas to measure and all the unknowns are abstracted away.
CO2 has few very narrow absorption bands. The amount of energy absorbed is small.
If CO2 was the culprit, it would be very easy to measure over dry deserts. Heat radiates into space very quickly at night with a dry atm. A temp difference of up to 40deg F is observed. Has this changed? It should if CO2 is so significant.
But CO2 is not that significant. H2O is but it is very difficult to model. So, blame CO2. Correlation is not causation, and CO2 is 'bad' because it is released by burning fossil fuels.

And why should the socialists be trusted? After all, the oil leases on in the Gulf of Mexico are sold by the US Govt. The US Govt earns billions from those leases and from the taxes generated.
Socialists want in on the action? Or are they too pure? They will just sell their votes to socialists like Obama to keep him in power. Why do you trust Obama after you vote for him? He won't need you any more but he will want more money.

The point with regards to deep water drilling, it's very much like running a nuclear reactor. It's a sophisticated technology that works well in it's design parameters. And just like a nuclear reactor, if something goes wrong, it can quickly change from an localized property destruction to scales the size of the gulf. One nuclear plant has the potential to make un-inhabitable an area the size Pennsylvania. One deep sea oil well could do the equivalent damage to its location on that scale (as we saw happen in the Deepwater Horizons disaster).

Those with the greater powers impose their wills on others so as to advance their own self-interests. Less powerful individuals cannot stand to defend against all such.

Who decides what billions of individuals would do if 'given' the means?
In China:
"Many people feel that too little of the countrys spectacular growth is trickling down to them. Migrant workers who seek employment in the city are treated as second-class citizens, with poor access to health care and education. Land grabs by local officials are a huge source of anger. Unrestrained industrialisation is poisoning crops and people. Growing corruption is causing fury. And angry people can talk to each other, as they never could before, through the internet."
"That bias towards control is understandable, and not merely self-interested. Patriots can plausibly argue that most people have plenty of space to live as individuals and value stability more than rights and freedoms"

The federal govt already heavily regulates the communications industry. If the regulations were removed, there may be competition for internet service in rural areas.
I live in a semi-rural area. I have one cable company choice, two cable satellites, and ATT, and wireless.
But there are at least three cable companies in the area. Why can't I choose? Local govts sell franchises to these companies limiting competition.

They can buy insurance like everyone else.
But the federal govt is the ONLY provider of flood insurance.
If owners and builders had to depend upon private flood insurance and there was NO chance of any govt bailout, I suspect property prices would be quite different in high risk zones like the entire eastern seaboard and New Orleans.
