Pollution: consequences of the greenhouse effect

Climate change and consequences of the greenhouse effect: worrying coincidences.

By rejecting the pollutants defined above into the atmosphere, man does not only destroy himself, he would upset the natural balance of regions, then on an even larger scale, of the entire Earth. The main consequence is the greenhouse effect, which results in a very sudden increase, on a geological scale, in temperatures. But given the novelty of the greenhouse effect, scientists and meteorologists can only formulate more or less plausible hypotheses about the consequences of this greenhouse effect.

Inundations in the sum (spring 2001)

The main climatic consequences (disasters) of the increase in average temperatures (greenhouse effect and human activities) on the planet would be:

- numerous storms, exceptional in their intensity or frequency (little known phenomena like "el niño" and "la niña")

- floods (or droughts): frequent in France. More than 600 dead in Algeria in November 2001.

- ice melting: at the current rate of temperature increase, 95% of the mass of alpine glaciers will have melted in 2100 (92% of the mass of Mount Kenya glacier has already disappeared). For the first time (Summer 2000) liquid water was observed at the North Pole.

- Weather aberrations: rainy periods in summer and heat waves in spring, temperatures playing with yoyo ...

- Reduction in snow duration ... (with the tourist consequences that this induces, in the Vosges for example, snow has been absent for 10 years)

-… or, on the contrary, the duration of snowfall considerably increased by the deregulation of sea currents, in particular the Gulf Stream. If it no longer existed there would be a period of 4 to 6 months per year of snow cover on Europe up to Greece. And on the contrary, a sharp rise in temperature in America (New York, which is however at the lattitude of Spain has always known long periods of snowfall)

- spread of tropical diseases in temperate countries

- disappearance of many species, sensitive to temperatures (insects) but above all whose ecosystem or food chain is threatened by climate change

- rising sea levels, more by the expansion of ocean water than the melting of terrestrial or polar ice

- ultimately 92 million humans potentially victims of a 50 cm rise in sea level. (broken food chain, flooded delta, etc.); imagine this number for 2 or 3 meters elevation

This list is not exhaustive and certain consequences of the greenhouse effect are still unknown. Be that as it may, the human and financial costs will be enormous.

Estimation of the cost of pollution in CO2.

The Kyoto conference estimated the preventive cost of a ton of CO2 between $ 20 and $ 40. This cost has been estimated in anticipation of the potential damage caused by CO2. In France, this preventive and virtual cost amounts, just on transport, to 1.7 billion francs / year.

For example, the storm of December 1999 "cost" in France: 88 dead and 150 billion francs.

How to counter this ecological suicide?

Solutions that are quickly implemented, inexpensive and do not upset the current financial challenges must absolutely be developed in order to hope to limit the almost irreversible damage (on a human scale) that we are causing. These solutions are as much behavioral as technological…

Because pollution will not affect, like some very publicized diseases, that a part of the population, but all humanity, nobody will be spared even if the poorest populations will be the hardest hit (as we have seen with the murderous floods in Honduras and Algeria).

Obviously, nothing is scientifically proven yet but common sense makes it easy to feel the major risk towards which we are going… and that it might be high time to develop and apply solutions instead of continuing to defend certain corporatisms ...
