What's in a Name: the politics and reality of global climate change


   When scientists discovered that the average temperature of the oceans was increasing, it was picked up by the media as "global warming". While I don't know whether this name was embraced by the scientific community or not, it wasn't a bad name -- at a scientific level. A much better name would have been "global ocean warming" -- for reasons to follow.

   A name is a powerful thing -- attitudes, and historical associations, come along with names. If a highly anti-patriotic thing is NAMED something patriotic then it is easier to associate it with positive, patriotic, meanings. This is just how our brains work -- we associate names with other things connected with the names. Politicians, Public Relations people, and advertising agencies make use of this to a great degree.

   If the word "global warming" is used then it can be MIS-used. If there is a huge snowstorm, it can be used as "evidence" that it is "obviously" NOT warming all over the globe. The more precise, and accurate, the word that is chosen, the more difficult it is to skew the interpretation. As mentioned earlier, it would be more difficult to misinterpret "global ocean warming" -- since a snowstorm is not immediately connected to the ocean (although it is actually true that the ocean warming might directly help the snowstorm to happen).

   Of late, the dialog has mostly changed to that of "global climate change". This is associated with the effect of "global ocean warming" -- but it seems to have been easier to migrate to this phrase than to expand upon the "global warming" media phrase. It is a reasonable phrase and much more difficult to subvert by politicians as there IS (unfortunately) increasing indications of global changes in the climate.

   The other part of the "discussion" (actually more of a taking of sides) -- beyond whether or not global climate change is happening -- is whether it has been caused by human activities. It will be impossible to totally prove this as that would require comparing two parallel worlds -- one world where changes in energy use and other human activities took place in a timely manner and comparing that to our current world.

   When historical evidence is examined, it shows how, and when, such global changes in climate have occurred before. This evidence does give us some ideas as to how various components (Carbon Dioxide in atmosphere, Ozone levels, water levels, average temperature, etc.) work together to change the climate and it does indicate how ongoing, present, changes are likely to affect climate. Politicians are correct that climate change has occurred many times over history. However, the rate of change of factors that have been occurring over the past 100 years has only been found in association with large scale catastrophes (huge volcano eruptions, widespread biologic changes, and so forth).

   This rapid change is the most scary part of global climate change. Humans are very adaptable. In fact, a great name for the species would be homo adaptabilis. If a desert turned into a a wetland over a period of a couple hundred years, people would adapt. In fact, much of the Sahara desert was once a tropical forest at one time (but the change was much, much slower). If the coastline disappears under water an inch a year, people will adapt. That is our current goal -- to slow down the rate of global climate change to allow people to move from one place to another, to allow changes in basic crops grown in an area, to allow people to change housing and energy use, and so forth.

   But, all of this is still an exercise in the dangers of allowing the media to choose a phrase to describe something. Insist on precision in descriptions. Refuse to use labels that are obviously inaccurate -- reverse it by saying "the so-called xxxxxxx". When a debate arises where one side is labeled as "pro-AAAAA" then insist that the other side be called "anti-AAAAA" rather than "pro-BBBBB"

   What misuses of labels have been the most upsetting for you?

Polls and Surveys: Not often a many-splendored thing

     It seems that election season is usually the time for a plethora (so many that a person gets sick of them) of polls. Surveys happen all...
