The effect of global warming on the planet is so great it will suppress the beginning of the next ice age, a new study has found.
Researchers say the relationship between of insolation and CO2 concentration in the atmosphere has been key to the last eight glacial cycles in Earth's history.
But rising man-made greenhouse gas emissions since the Industrial Revolution began in the 18th century could mean the balmy period will last for 100,000 years, they wrote in the journal Nature.
The findings suggest human influences 'will make the initiation of the next ice age impossible over a time period comparable to the duration of previous glacial cycles,' they wrote.
'Even without man-made climate change we would expect the beginning of a new ice age no earlier than in 50.000 years from now - which makes the Holocene as the present geological epoch an unusually long period in between ice ages,' explains lead author Andrey Ganopolski.
'However, our study also shows that relatively moderate additional anthropogenic CO2-emissions from burning oil, coal and gas are already sufficient to postpone the next ice age for another 50.000 years.
'The bottom line is that we are basically skipping a whole glacial cycle, which is unprecedented.
'It is mind-boggling that humankind is able to interfere with a mechanism that shaped the world as we know it.'

We’re scientists with spectrometers analyzing the CO2 content of the atmosphere here 100,000 years ago? What bull nerd.
On another note, I'm glad to know there's not Ice Age coming because nobody wants to freeze to death.
I grew up in Montana and I got the heck out of there when I was 18 to go to college and I do not miss snow or ice.
No ice age for another 100,000 years? Darn it, I wanted to see 5 feet of snow on my palm tree. I guess, I have to go to work tomorrow. I wanted to call in because of an ICE AGE...
These bought and paid for ~scientists~ are F’d in the head.
If the global warming theory was correct, then this would be a valid inference. The question therefore is whether it is correct. But this is the first time I’ve heard pro-AGW science acknowledging that our climate is a hybrid of natural variation and human modification. This has actually been fairly widely accepted among skeptics — not all skeptics assign zero as the weighting of human modification. A commonly held position is to assign one quarter or one third of the warming observed in recent decades to greenhouse gases and/or urban heat island expansion, and the other two thirds to three quarters to natural variability.
Ice age climates typically involve global cooling of about 5 to 8 degrees (Celsius). This is where their concept comes from, a human warming factor of 2-3 degrees (which is what their theory predicts) would partially offset that natural chill and leave us with something more like the Little Ice Age (Maunder) climate.
It should be understood that nobody recently was talking about an imminent ice age. That was a view popular in the 1970s but it became discredited around the time of AGW but for an independent reason, namely, the growing acceptance of the Milankovich hypotheses. Those combine three different features of the earth’s orbital relationship to the Sun and have an almost perfect correlation with known ice age chronologies in the past million years (we’ve had basically four major glaciations and are now in a fourth inter-glacial).
It turns out that one Milankovich factor is currently rather flat and not pointing us towards an imminent ice age but a steady-state climate for five to ten thousand years. Then that factor joins two others that are pointing to cooling, meaning that without any human modification the next ice age was not likely to start for about eight to ten thousand years yet. We are probably somewhat past the peak of inter-glacial warming but the recent century was almost as warm as the peak (which appears to have been about five thousand years ago).
Personally, I think this new announcement may be true. We may be producing enough greenhouse gases to overcome the ice age process at least for a while if not right to the maximum time of cooling. And as there is a feedback loop (the advancing glaciers cool the atmosphere), if we can avoid one starting, it may never totally get going. We may instead see expansion of mountain glaciers and some expansion of recently shrinking marginal arctic glaciers like those on Baffin Island.
This may be a face saving situation for the climate change crowd who must know by now that they are not going to panic the world into economic changes that we can’t afford or sustain. They may say, “well, listen, we were right, but now we think this is good because there won’t be an ice age.” Whatever, if it ends the farce we have been enduring these past three decades, I will raise a glass to it and then let’s realize that fairly soon technology will move far beyond the current reality, and who knows, we may have climate control long before the Milankovich factors get to the nasty zone. An ice age in this world would be a disaster on a scale not even imaginable to most of us. It would force all of us to try to live between 30 degrees N and 40 degrees S latitude. Good luck with that. The folks who are there now probably don’t want that much company.
Well, thank goodness. I think I’ll light a cigar.
I am still trying to understand why so many people believe the long-range predictions of people who cannot even predict the weather for the next 7 days with any reliability.
Centrifugal force will whip us out of orbit and send us sailing outside of Pluto's orbit.
There is no way to avoid our fate once we past the Global Warming point of no return.
We are all doomed to die and turn into stardust.
Soooo, yeah, let's make sure we don't interfere with that.
Damned! I just bought a new parka. Back to the closet it goes.
BAD, BAD, GLOBAL WARMING!!
You’re going to delay the ice age 50,000 years, so we humans WON’T be buried under billions of tons of ice!
How dare you mess with Mother Nature!
We were all hoping that the human race would be snuffed out, and here you are going to allow us to stay around and kill the planet! ARG, you’ve ruined all our fun.
‘It is mind-boggling that humankind is able to interfere with a mechanism that shaped the world as we know it.’
And they are complaining about this! If so, thank God for the modern Industrial Age for saving us from another Ice Age!
They should all move to Spitzenberg or Greenland and see what they are missing.
And I had a picnic planned for the first Saturday after the 102nd Millenium!
Drat!
Good. I hate being cold.
I rake this stuff out of the horse corrals twice a day.
this is absolutely breath-taking in its absurdity.
No matter what we do, climate will change into the next ice age ?
then doing anything makes us batsh$t crazy.
