Much debate in the last five years about the greenhouse effect has centered on interpreting temperature numbers generated at weather stations all over the world. The data from these thermometers are averaged and plotted in attempts to determine just how fast the earth has heated up since the measurements began. There is now no doubt the world is getting warmer. The thermometers show that the world is warmer now than at any time since the measurements started. The year 1990 was the hottest year in the last century. Together with 1991, the years of 1983, 1987, 1988, and 1989, have been measured to be the warmest 6 years in the last hundred years. 1991 was the second warmest year of the past century, perhaps due to the eruption of Mt. Pinatubo during that year. The ash from the volcano in the upper atmosphere blocks some sunlight to earth, and is expected to generate a temporary two or three year cooling effect. After that time, most ash particles will have settled back to earth, and most scientists expect to see the global warming trend continue.

Global warming
"Global warming will be the greatest environmental challenge in the 21st century."
- Vice President, Albert Gore.
Global warming is happening as we speak. Wether the main cause is man made or just another climate change as seen throughout history is a debate for itself that we will not enter much here.
The fact is, however, that the temperetures is rising continuously in this epoke of time.
We will look upon the worldly changes to expect as a reaction to this fenomenon.
