A look at the temperature variation curves, especially on very short timescales, clearly shows that the climate varies constantly and sometimes very rapidly. The temperature during the Middle Ages was two degrees (Centigrade) warmer than it is currently, and was followed by the Little Ice Age. During the sixteenth century, the glaciers dipped dangerously close to the hamlets in Chamonix before a spell of milder weather set in. The glaciers in the Alps have been melting since the late nineteenth century.
Temperature variations are due primarily to astrophysical events.
They are anterior to the CO2 variations, meaning that the temperature variation induced the CO2 variation, and not the reverse. Still, it is no doubt possible that a substantial CO2 variation might have an influence on a temperature variation, but it has never been seen before.
The increase in anthropogenic CO2 is due to the burning of fossil fuels – coal, oil and gas. This accounts for only a fraction of the greenhouse effect, since 50% of the effect is already due to water vapor from the oceans.
So something doesn’t add up.
You might think that the nuclear lobby had succeeded in convincing greenies that nuclear-generated electricity is the best of the worst solutions. Amazing!
Literally, intelligence is the capacity to understand and to connect events. The Neanderthals and the Cro-Magnon had solid intellectual capacities to survive in the world that was theirs, and their perceptive and analytical capacities were probably as good as ours. What has changed is the state of knowledge. We benefit today from a vast accumulation of knowledge, but are we any more intelligent than they were? In view of our huge miscalculation with respect to exponential growth, the answer is definitely NO.
Money is no more than an abstract concept, a level of confidence in an exchange. For a long time, pieces of precious metal were used as a safe medium of exchange for goods. Later, when paper was used, it represented an amount of precious metal that was carefully guarded in a central bank reserve. At any time, the bearer of paper money could exchange it for the metal. In 1970, the United States went off the gold exchange standard, choosing to link the dollar to oil instead. It seems rather incongruous to assert one’s confidence in an exchange that is based on a product which gets burned!
Although it has no intrinsic value, money still reflects a level of wealth produced. This is why we can say "tell me how much you earn and I’ll tell you how much you pollute.”
Coltan is an ore that consists of the minerals colombite (containing niobium, row 5 in the periodic table of elementsand tantalite (containing tantalum, row 6 in the periodic table of elements).
Tantalum metal is highly corrosion and heat resistant, with a melting point of 2996°C[CN5] and a boiling point of 5800°C[CN6]. It is used in the capacitors of miniature electronic equipment, e.g. mobile phones. While only a few milligrams of this strategic metal goes into each piece of equipment, more than three billion pieces of equipment have been built. The Iraq and Afghanistan wars are being fought for oil, but the war in Rwanda was over coltan. The mineral is even mentioned in a number of UN reports on African conflicts – so one wonders how a certain foreign affairs minister could ask why we are unable to stop the wars in that region.
Cellphone pollution arises from the fabrication process, not from the use of such devices.
Bizarre individuals whose activity is purely recreational. They are the “cream” of the service sector and will disappear once the surplus from the primary and secondary sectors declines.
The non-materialistic human needs no sports activity to keep in physical shape.
The arts will be a matter for each individual.
A tourist has no particular need to travel, so when walking becomes the only way to go somewhere, he’ll stay in place.
