Global Warming Could Save Us from the Next Ice Age, So Burn As Much in the Way of Fossil Fuels As We Possibly Can!
Celebrate! The University of California - Santa Barbara (from which my son graduated) has made the greatest news imaginable. Researchers have found it is inevitable that another ice age will strike us in 10,000 years sharp, which might seem bad for mankind if we haven’t relocated to Mars by then, but there is a golden lining to the story: global warming could save humanity.
I’m not kidding. Here is what UCSB tells us:
Beginning around 2.5 million years ago, Earth entered an era marked by successive ice ages and interglacial periods, emerging from the last glaciation around 11,700 years ago. A new analysis suggests the onset of the next ice age could be expected in 10,000 years’ time.
An international team, including researchers from UC Santa Barbara, made their prediction based on a new interpretation of the small changes in Earth’s orbit of the sun, which lead to massive shifts in the planet’s climate over periods of thousands of years. The study tracks the natural cycles of the planet’s climate over a period of a million years. Their findings, published in Science, offer new insights into Earth’s dynamic climate system and represent a step-change in understanding the planet’s glacial cycles.
The team examined a million-year record of climate change, which documents changes in the size of land-based ice sheets across the Northern hemisphere together with the temperature of the deep ocean. They were able to match these changes with small cyclical variations in the shape of Earth's orbit of the sun, its wobble and the angle on which its axis is tilted.
“We found a predictable pattern over the past million years for the timing of when Earth's climate changes between glacial ‘ice ages’ and mild warm periods like today, called interglacials,” said co-author Lorraine Lisiecki, a professor in UCSB’s Earth Science Department. One type of change in Earth's orbit was responsible for the end of ice ages, while another was associated with their return.
“We were amazed to find such a clear imprint of the different orbital parameters on the climate record,” added lead author Stephen Barker, a professor at Cardiff University, in the UK. “It is quite hard to believe that the pattern has not been seen before.”
Predictions of a link between Earth’s orbit of the sun and fluctuations between glacial and interglacial conditions have been around for over a century but were not confirmed by real-word data until the mid-1970s. Since then, scientists have struggled to identify precisely which orbital parameter is most important for the beginning and ending of glacial cycles because of the difficulty of dating climatic changes so far back in time.
The team was able to overcome this problem by looking at the shape of the climate record through time. This allowed them to identify how the different parameters fit together to produce the climate changes observed.
The authors found that each glaciation of the past 900,000 years follows a predictable pattern. This natural pattern — in the absence of human greenhouse gas emissions — suggests that we should currently be in the middle of a stable interglacial and that the next ice age would begin many millennia in the future, approximately 10,000 years from now.
“The pattern we found is so reproducible that we were able to make an accurate prediction of when each interglacial period of the past million years or so would occur and how long each would last,” Barker said. “This is important because it confirms the natural climate change cycles we observe on Earth over tens of thousands of years are largely predictable and not random or chaotic.” These findings represent a major contribution towards a unified theory of glacial cycles.
“And because we are now living in an interglacial period – called the Holocene – we are also able to provide an initial prediction of when our climate might return to a glacial state,” said co- author Chronis Tzedakis, a professor at University College London.
“But such a transition to a glacial state in 10,000 years’ time is very unlikely to happen because human emissions of carbon dioxide into the atmosphere have already diverted the climate from its natural course, with longer-term impacts into the future,” added co-author Gregor Knorr from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research.
Could it be any better news? Impossible. It’s so good Al Gore and John Kerry were seen at a bar somewhere in Alexandria, Virginia, discussing what their next career moves might be. Reportedly, Gore hopes to be a fortune-teller and John Kerry plans to be a private jet test pilot.

That's a good argument for rebutting the climate doomsters. But I suspect that the effects of a bit more CO2 are likely to be minor and transient, and not nearly large enough to offset the ginormous forces, astronomical in scope, that are driving the glacial cycle. We are officially well into the neoglacial phase of the current interglacial. That's the part right before the ice comes back, and humanity is knocked back to the dark ages.
The history of the earth is important, gore and kerry not so much. But the human creation of CO2 is of no consequence to the earth’s temperature. But do climatocatastrophists actually believe in physics, thermodynamics, chemistry, or even just any non emotional facts? No, I don’t think so but then some of them think the earth is flat and orbits around themselves.
