Global Warming or Climate Chaos: What’s in a Name?
This winter has set record lows in many states, a fact the editor of our conservative local newspaper, and others of his ilk, must be relishing. “There’s no global warming,” I can imagine him crowing. “It’s all a liberal hoax.” Such distorted logic reveals either an appalling ignorance of the meaning of “average,” or a cynical attempt to intentionally mislead.
Truth is, the names bestowed on various scientific phenomena are often whimsical in origin. Nobel laureate (1969) Murray Gell-Mann, for example, appropriated the term quark — one of three elementary particles and fundamental constituents of matter — from a nonsensical line in Finnegan’s Wake: “Three quarks for Muster Mark!”
Then too, the term Big Bang originated not from a scientific paper, but from a 1949 BBC broadcast. Astronomer and atheist Fred Hoyle coined the term to deride an hypothesis by the late Belgian Catholic physicist Georges Lemaitre. Lemaitre believed that the universe might have originated from a singular event, which he termed the “primeval atom.” Hoyle’s term of derision stuck instead.
Sometimes a whimsical term — like black hole — fits the phenomenon well. And sometimes it’s an annoying distraction. Most physicists rue the day the Higgs Boson was dubbed the “God particle.”
The trick for scientists is to find a term that conveys the essence of the phenomenon while remaining accessible to the general public.
Well, both. Yes, the climate is warming, but the term trivializes what is vastly more complex. “Climate change” is a more descriptive, but ho-hum. “Climate disruption,” currently in vogue, is better. “Climate destabilization” is most accurate, but geeky. And “climate chaos” is where we’re headed. For the moment, let’s run with climate destabilization.
Imagine driving a car with a front wheel out of balance. At moderate speeds, the car shimmies. At high speed it shakes. And at too high a speed, the driver loses control.
By continuing to burn fossil fuels, pumping ever more carbon into the atmosphere, we humans are stomping ever harder on the climate accelerator. If we don’t soon take our foot off, the climate, as we know it, will spin out of control.
The National Oceanic and Atmospheric Administration (NOAA) began measuring atmospheric carbon dioxide (CO2) in 1958. Since then annual mean CO2 concentration has risen steadily from 315 parts per million (ppm) to 400 ppm, as shown above in the “Keeling Curve.” In 2001 George W. Bush appropriately honored its originator, Scripps Institution scientist Charles David Keeling, with the Presidential Medal of Science.
As a direct consequence of rising atmospheric CO2, global mean temperature has risen about 1.4F since 1880 and is projected to rise another 4-10F by the turn of the century — unless the world weans itself quickly from fossil fuels. And wean we must, because the upper limits of this projection are incompatible with life as we know it on planet earth.
But climate destabilization has many more faces than “global warming.” Here are just a few:
- On average, sea level has risen about 7 inches in the last century, and the rate of rise is speeding up. By century’s end, the additional rise is now projected at between two and 7 feet, putting more than 600 million low-landers, and some of the world’s greatest cities, at risk.
- Seas are rising for two primary reasons: water’s slight expansion as it warms; and runoff from melting glaciers and ice caps. The National Snow and Ice Data Center reports that, since 1979, the global extent of sea ice has shrunk on average by 135,000 square miles — or about half of Texas — per decade.
- Particularly troubling is Greenland’s ice sheet, which has diminished by nearly three trillion tons in just the past decade, as observed by NASA’s Gravity Recovery and Climate Experiment (GRACE) satellite.
- In addition: “Glaciers all over the world have been melting for at least the last 50 years, and the rate of melting is speeding up.” Billions of people worldwide depend on glacial melt for drinking water. It’s been said that the next world war will be fought over water.
In the same way that an unstable automobile wobbles from side to side, an unstable climate swings from extreme highs to extreme lows.
- Recently NASA and NOAA independently confirmed 2014 as the hottest year on record. All 10 record hot years have occurred since 1998.
- In February 2014, the BBC reported on climate research that reveals how a warming Arctic destabilizes the jet stream, producing wilder oscillations and paradoxically, colder winter temperatures in parts of the US and stormier weather in Europe. You can watch a simulation of the jet stream’s oscillations here.
A destabilized climate also produces extremes of drought and precipitation.
- On March 2, the LA Times reported on a recent paper by the National Academy of Sciences (NAS) that directly links California’s prolonged drought to climate disruption. The NAS study follows closely on the heels of a February 2 climate article in the premier journal Science titled “Unprecedented 21st century drought risk in the American Southwest and Central Plains.”
- “In the Midwest and Northeast, big storms that historically would only be seen once every 20 years are projected to happen as much as every 4 to 6 years by the end of the 21st century,” according to the National Wildlife Federation’s flood assessment.
As the climate further destabilizes, climate disruption morphs into climate chaos.
- Hurricane Sandy’s storm surge — which flooded sacred ground zero of New York’s World Trade Center — exceeded the previous record surge by a staggering four feet.
- In drought-affected regions all over the world, wildfires are growing in both frequency and size, as reported in the NY Times in 2013.
- Munich Re — a global insurance company with unmatched expertise in evaluating risk — reported that its weather-related losses in the US have increased four fold since 1980.
We could go on and on. Reports stream in daily: from multiple disciplines, organizations, and regions of the world. Human activities — primarily the burning of fossil fuels — have destabilized the climate, and the trends are all in the wrong direction.
If these aspects of climate were instruments in an airplane’s cockpit, then every alarm would now be going off simultaneously (to adapt an analogy from This Changes Everything by Naomi Klein).
What’s in name? Everything. “Global warming” just doesn’t cut what we’re up against.

The author's book Reason and Wonder: A Copernican Revolution in Science and Spirit (Praeger, 2012) further explores the interface between science, mythology, spirituality, and meaning. According to Ursula King of the Institute for Advanced Studies at the University of Bristol, Dave Pruett's Reason and Wonder (Praeger, 2012) "opens up [an expansive worldview] of true audacity and grandeur that will change your thinking forever."
