The global warming phenomenon has been extensively studied over the last decades, and remains at the top of the environmental agenda in almost every country of the world.
What does that mean? The more carbon dioxide in the atmosphere, the more pronounced the greenhouse effect becomes, that is, the more radiation emitted by the earth is trapped in the lower atmosphere, producing an increase in temperature.
The climate of Greece will become drier due to the decrease in rainfall by 20-30% in the summer and by 10% in the winter.
According to the predictions of IPCC (2007), by the end of the century sea levels are expected to rise by 20 to 59 centimeters.
The impact for this is dramatic because Greece has a 16,000 km coastline. One third of all Greeks live at a distance of up to 2 km from the coast. Ninety percent of the country's tourism infrastructure are on coastal areas, and the same holds true for the 35% of productive arable land, all ports and most large cities.
The health of millions of Greeks will be in danger because of the rapid increase in the number of days with very high temperatures.
