View Full Version : Global Warming is Accelerating Faster than can be Naturally Repaired

It appears the Earth's climate has the ability to naturally regulate atmospheric carbon dioxide levels. Historic records extracted from ice cores show quantities of CO2 have varied widely in the last hundreds of thousands of years. This evidence appears to support the global warming critics view that current observations of the human-induced greenhouse effect is [...]

From the link:

His study states that in the last 600,000 years the carbon dioxide levels have fluctuated only by 22 parts per million. Since the 18th century, human activity has injected 100 parts per million. Humans have increased the quantity of carbon dioxide 14,000 times more than any natural process is capable of doing. This increase has negated any chance for the climate to naturally bring carbon dioxide levels back down to pre-industrial levels in the short term. If we were to stop all emissions tomorrow, it would take the planet hundreds of thousands of years to recover naturally.
http://www.geocraft.com/WVFossils/Carboniferous_climate.html indicates that current levels of both CO2 and temperature are relatively low for the most recent 600 million years. http://www.geocraft.com/WVFossils/ice_ages.html argues that the current rate of warming is typical for an interglacial period during an ice age which we are currently muddling through.

I haven't seen the rationale supporting: Humans have increased the quantity of carbon dioxide 14,000 times more than any natural process is capable of doing nor for: it would take the planet hundreds of thousands of years to recover naturally.

I don't believe we are in such dire straits, but, if we are, we should start building dikes and installing pumps to take care of trapped stream runoff even if the energy we use doing this accelerates the warming. Could it be that there are global political strategists afoot that function to destroy the most advanced technically competent country/culture by sowing seeds of self doubt and indecision that lead to the adopting of a set of political decisions equivalent of that well known trait of lemmings to self-destruct?

Hey! Fermi, I think I know what happened to them.

Perhaps this process led to the destruction of the British Empire (http://en.wikipedia.org/wiki/British_Empire).

Lemmings breed in the offshore islands and do not drown, as is popularly believed. As far as global warming goes, I hate swimming in cold waters so...Yay!...buy property 300 feet above sea level and wait for the ocean to make it waterfront. pete:shifty:

I'm just going to say that I think every person in the world has at least one person who supports them, and I'm the one who supports Al Gore.

...and I'm the one who supports Al Gore. That's a lot of mass, you must be a Higgs boson. Is it true that Al channels the Easter Bunny and the Tooth Fairy for his global climate change data and doom and gloom forecasts?


Since the 18th century, human activity has injected 100 parts per million. If the authors of the article were referring to CO2, how do they know what the ppm of CO2 were in 1800?

Assertions made in the story linked by Fraser seem to me to be hyper-ridiculous, and therefore in need of challenge. Can someone provide a tutorial as to why the assertions should be believed?

I didn't think there was any controversy regarding atmospheric CO2 concentration at the commencement of the industrial era.

Is there something seriously wrong with the conclusions made in Historical CO2 Records from the Law Dome DE08, DE08-2, and DSS Ice Cores (http://cdiac.ornl.gov/trends/co2/lawdome.html)?


. . . The Law Dome site satisfies many of the desirable characteristics of an ideal ice core site for atmospheric CO2 reconstructions including negligible melting of the ice sheet surface, low concentrations of impurities, regular stratigraphic layering undisturbed at the surface by wind or at depth by ice flow, and high snow accumulation rate. . .

. . . The ice cores were dated by counting the annual layers in oxygen isotope ratio (δ18O in H2O), ice electroconductivity measurements (ECM), and hydrogen peroxide (H2O2) concentrations. For these three parameters, each core displayed clear, well-preserved seasonal cycles allowing a dating accuracy of 2 years at 1805 A.D. for the three cores and 10 years at 1350 A.D. for DSS. . .

I saw Al Gore's lecture/movie. Best Part:Futurama Clip. Worst Part: No Answers. Not even an attempt at trying to think of and show ideas of how we can reduce greenhouse gases. Just a lot of charts, and folksy reminisces. I half expected him to pull out the ol' banjo, but that would be far too entertaining. I think we need answers, practical, concrete, money making answers. We need to find a way for companies to make money off of combating globule warming, besides ineffectual feel good acts for the rich and guilty. For example I read a fascinating article on growing hydrogen from algae. From what I could see, it looked possible. Yes, like any hydrogen process, it used energy to make energy, but one could say that about ANY process, and this didn't use gigawatt's of electricity or chemical energy. The future, even when if we do switch over to replaceable fuel methods, won't be some free energy paradise, but it will WORK.

How long does it take for atmospheric diffusion of CO2 to become stabilized? What is the rationale for asserting that CO2 measured at Antartica is representative of global concentrations free from local effects such as southern hemisphere volcanoes? Thanks for the link; it's a good move in the right direction.

Comparing antarctic CO2 with tropical CO2 concentrations over time suggests the atmosphere is mixed well enough for these purposes.
