The effect of man made global warming on milankovitch cycles?

Question

How will feedback responses to changes in the earths movement be altered by the additional C02 in the atmosphere, what impact will this have on the intensity of the future glacial period?

Any ideas?

Answer 1

Are milankovitch cycles the drivers of the interglacial/glacial cycle? Hard to say, being that it is such a weak forcing, even with a CO2 feedback. Could Milankovitch cycles overcome any CO2 induced warming (if that is the cause of the recent warming)? Again, it is hard to say, because if such a forcing could throw us into 100,000 year long glacials with mile thick glaciers covering most of the Northern Hemisphere and large portions of the Southern Hemisphere, seems like it could make a dent.

There are various other theories that attempt to explain the glacials, but one of the more prominent is changes in the Sun's output:

Bob, what the h**l does foxnews' opinion on global warming have to do with this? Sorry I don't follow groups or the news just because they are conservative, liberal, democrat, or republican, I follow the science (data and evidence, not just scientific organizations). And the science just isn't there.

And of course you know Dr. Allegre is a socialist and Steve McIntyre is a democrat, right? I don't care about political affiliation.

IF YOU WERE TO RELEASE CO2, EXHAUST, GASES AND CARBONS OR ANY OTHER SUSTANCE OF THIS NATURE,  IT WOULD DECIPATE WITHIN EYESIGHT.  CLICK ON THIS   http://www.socyberty.com/Activism/First-...    NOW THAT YOUR DOWN ON THE GROUND== HAVE A NICE DAY.EARTHS AXIS DOES'NT HAVE ANYTHING TO DO WITH  WHATS CAUSING G.W. ITS A HIGHER INTELLIGENCE THAN OURS THAT IS THE CAUSE.

Answer 3

Hard to say.  In the past the cycles have always been able to overpower CO2.  But they've never had to deal with THIS much CO2 before.

Is FoxNews the liberal media?

"While evidence suggests fluctuations in solar activity can affect climate on Earth, and that it has done so in the past, the majority of climate scientists and astrophysicists agree that the sun is not to blame for the current and historically sudden uptick in global temperatures on Earth, which seems to be mostly a mess created by our own species."

Answer 4

my take is that the milankovitch cycles are in the order of thousands, or tens of thousands of years, whereas global warming is / will be, measured in decades, at the most.

unfortunately, the Long Ranger is not going to ride up and save us from ourselves.

(Does that date me, or what?)

we've created the problem, and if it's going to be fixed, we'll need to do it.

the bad news is that it'll take as long to fix it as it did to create it.

we in the US today are nearly completely incapable of investing in anything for which we don't see immediate results, never mind investing quite a lot in something for which results won't be visible for decades.

one might note that an Islamic society would be far more able to do this than we are -- unfortunately.

in a somewhat vain attempt to ward off some of the negative comments that will undoubtedly come, this is not intended to promote Islam, it's just to point out a difference.

Answer 5

i was hoping the natural cycle would give us a breathing space, but according to analysis of the milancovitch cycles we are not due for another ice age for 20 odd thousand years chiz.

i read recently that if anth. warming exceeds 4 degrees we wont get the next one at all. sorry bit pissed, not fit to find reference. really sad about this, i thought it might be our 'get out of jail free' card...

Answer 6

CBS News correspondent Bernie Goldberg says the liberal mainstream media is largely ignoring the voices of scientists and academics who are skeptical of the notion that global warming is caused by human activity.
