MONTGOMERY VILLAGE, Md., May 30, 2014 – Most reasonable people believe that Climate Change is real. What they don’t appear to agree is on its effects on the weather. Disagreement centers on two points:
- Temperature effects on the earth; and
- Extreme weather occurrences and other phenomena.
Those who oppose 1. above talk about the fact that surface temperature on the Earth hasn’t increased as predicted by Climate Change theorist in the last decade. They point at several studies that demonstrate that. This by itself is not sufficient proof. Some point out that increases in temperature would be less than the more than linear correlation with carbon dioxide concentrations.
The number of data points on temperature are by definition limited. Local weather, air particle pollution and other phenomena like El Niño can bias any readings. A study done some years ago theorized that the increase of particle pollution in the atmosphere as the result of more human activity in developing countries and volcanic activity could be causing the “shading” of the sun rays.
Another issue ignored by the doubters of earth warming theories is that there is evidence already of sea rise in many places of the globe and the melting of permanent ice in places like Greenland.
The doubters also point to a decrease of heavy-toll hurricanes and other violent weather in the last decade to discredit that man-made carbon dioxide increase has any effect on extreme weather. The fact is that when these fewer weather phenomena occur, they are more violent and cause more damage that in the past. In the case of hurricanes, the sea level rises can be a logical contributor.
It is also a fact that due to extended drought in the West of the US has extended the forest fire season significantly. The droughts in some places have broken records.
Many of those that doubt or openly dismiss the intensity and imminent effects of Climate Change do not disclose the source of their funding. Organizations like the Heartland Institute will not reveal their multimillion dollar contributors, and this is all legal. The Heartland Institute that has in the past defended tobacco corporations, has gone from being a total denier to preaching that Climate Change may be beneficial.
Unfortunately enough money has been spent in attacking Climate Change that only 35% of the public believes it is an important issue. The billions spent by the fossil fuel lobbies and the political right wing (opposed to new regulations) have been very effective.
Finally, it is obvious to anyone researching or just plain reading about Climate Change, that the natural phenomena overlaid the increase of carbon dioxide and other gases in the atmosphere is very difficult to study and predict. The precautionary principle tells us that if there are many signs pointing in a certain direction, it is a good idea to prevent its effects if they could be negative. The overwhelming majority of published works on this subject support Climate Change as the result of human activity.
