We wish the term “global warming” had never been conceived. With a third of the U.S. population having its brains beaten out by snow and near-record cold temperatures (at this writing New York City expected a low of seven degrees this morning and Chicago looked forward to a wind-chill of about 40 below), how can anyone think about global warming?
Just hold your horses—or kangaroos—as we take a look down under. The Aussies have just lived through their hottest year on record. And so far, things don’t look much cooler for 2014. While the cities on the east coast of the country have decent temps right now, it might not be a good idea to visit the outback, and we’re not talking steak houses here. Australia’s Bureau of Meteorology reported that 34 locations in Australia set all-time high temperature records between Dec. 30 and Jan. 4. One area of south central Australia had highs above 120 degrees. These high-low ranges are why “climate change” is a better term than “global warming.”
Remember, we just experienced mega Typhoon Haiyan in the Philippines, preceded by “Frankenstorm” Sandy on the U.S. East Coast. Which brings us to the point. Don’t let the bitter cold that is saturating broadcast news misdirect your attention. In California, where we live, 2013 was one of the driest years on record. The northern part of the state, including the San Francisco Bay Area and the snow-dependent Lake Tahoe area of the Sierra Nevada, is practically gasping for rain and snow. We are experiencing week upon week of well-above-average temperatures. So while we are all looking at snow drifts on the tube, we feel this reminder is timely: THE EARTH IS WARMING AND THE SEAS ARE RISING. In other words, on average the surface temperatures on our planet are headed upward. And that means ice everywhere is melting faster than it is replaced.
According to the overwhelming majority of climate scientists, the preponderance of evidence places the blame on human activity. And no matter how energy efficient we become over the next century, adding three billion of us to the planet is going to make it all but impossible to reduce energy consumption overall.
Nancy Cole of Union of Concerned Scientists, writing in the fall 2013 issue of Catalyst, explains that “ … heat is also absorbed by oceans, causing water to warm and expand. Together, these mechanisms have caused the global average sea level to rise eight inches since 1880; some cities along the East and Gulf Coasts have seen even greater increases, from 12 inches in Miami Beach to 30 inches in Virginia Beach.” Cole refers to scientists’ projections that globally seas could rise an additional six to 16 inches by 2050. In the ensuing 50 years they could rise another two to six feet.
If there is one thing we have learned since diving into the myriad issues of the consequences of overpopulation, it is that such projections often don’t have merit when it comes to accuracy. 2013 for instance was supposed to be one hell of a year for Atlantic hurricanes. The reality, in a word: fizzle. But over the long haul, it is likely that the air will warm, ice will melt, and seas will rise. A lot.
That will mean that coastal cities will either be swamped or have to spend big bucks on stopping the seas. Beaches, and even a country or two, like the Maldives, will disappear. And future generations will wonder, “What the hell were they thinking back in the early 21st century? Or were they thinking at all? After all, didn’t they realize there were enough of us, even back then?
