“It's possible that other greenhouse gases such as methane could have contributed to the [PETM] warming,” Zeebe says. It's also possible that the models are underestimating the climate response to CO2 increases. If that's the case, it “would mean our understanding of the climate system is incomplete,” he says.”

OR maybe they are over estimating the effects of co2, but perish the thought since ignorance only works in one direction.

Bingo!

Rephrased: "- It's also possible that the models are underestimating the climate CO2 response to CO2 climate temperature increases. If that's the case, it “would mean our understanding of the climate system is incomplete,” he says.” -"

But scientists say they can't entirely blame the greenhouse gas for a curious spike in Earth's temperature 55 million years ago.

Dinosaurs driving SUV's?

[Jack Hammer]

Guess the people of Atlantis drove their cars back and forth to the pyramids a bit too often. Or was it the dinosaurs switching on their air conditioners all summer that did it?

All the charts I have seen show that CO2 concentrations have always risen after

I have come to the conclusion scientists are buffoons.

Don’t confuse genuine scientists with liberal agendists disguised as scientists.

Mine was a reply to poster Always Right at post #7. I think that perhaps we three are all on the same page?

I do not demean anyone who pursues scientific thought and process up and until, as you say, they bring in an agenda (for personal fame or fortune?).

I offered the examples of what was/could have been previously considered as scientific 'fact'. Reasoning being that the current "consensus" about the Earths climate could be just as inaccurate (and as deadly, health or economically).

There are effects both ways, but most of the effects of CO2 concentration on temperature occurred in the 0-100 ppm range (if we ever got that low, there would be no plant growth). Beyond that the temperature increase per unit increase of CO2 rapidly approaches zero because of the logarithmic nature of the effect. Temperature fluctuation due to seasonal variation, variations in insolation, variations in solar output, variations in orbit, etc., have a greater effect on atmospheric CO2 being sequestered in or released from ocean water.

Carbon dioxide (CO2) gets a bad rep for contributing to global warming, and deservedly so.

Talk about begging the question. Another writer who's afraid of not genuflecting to Algore and his minions.

New research reveals that something else also seems to have warmed the planet during that time, though no one's quite sure what it was.

How about the SUN!!!

[AFPhys]

Please, friend, stop associating the alarmists with being scientists. They are not following the scientific method, at all. Whether they realize it or not, anyone who believes that doubling CO2 will raise the temperature of Earth by even 3-4C is invoking magical thinking, not science, in order to do so. It may not even be their fault, but simply that they are accepting a magical amplification of CO2 effects programmed into the computer models.

Even if that is the case, any real scientist who comes up against this type of clear FACT that CO2 is not explaining their observations would say, “There is something wrong with the CO2 hypothesis.”, not, “we may not understand something here.”

Many of us who are true scientists understand that a hypothesis is not something to rally a “consensus” around, but that scientific method is to prove, if at all possible, that it is wrong. In the case of the CO2 hypothesis for GW, it has already been proven inadequate in many ways.

Unfortunately, alarmists have proven it adequate to garner more funding, and politicians have decided it is is worth giving that funding since it also gives them more power.

However, please don’t mistake alarmists and politicians for scientists.

If you haven't visited www.CO2science.org, take a look. They have results of studies on the effects of increased CO2 on plant life.

[Old Professer]

There’s no good news here, “ It’s also possible that the models are underestimating the climate response to CO2 increases. If that’s the case, it “would mean our understanding of the climate system is incomplete,”

This has already been picked up to mean that there are positive forcings we need to add to our models even though their character is uncertain; so far no negative forcings have made the list of possible model runs.

“However, 2009 does provide major challenges, in part because of escalating costs. Available funding does not provide for full year operations for both drillships, or for MSP operations, with the desired frequency. Chikyu will drill for only about five months and the JOIDES Resolution for about seven months. In addition to funding shortfalls, market conditions in shipyards have been extremely tight and have led to continuous delays in completing work on the JOIDES Resolution.”

The Joides Resolution drill ship overhaul ran a year late and cost over $100,000,000. Glad it made back into the headlines in time for the budget slug out.
