EXTREME WEATHER EVENTS
Those which until a decade ago were considered rare and abnormal events, from long we’re getting used to consider them normal. The weather, once predictable and repetitive, now it no longer is, and we are at the mercy of a climate which strangely shows us his madness and often at the same time, in different ways and in different places.
One example is the cold never registered in China, while at the same time a heat wave has hit Brazil. Last September in Siberia the temperature reached-47 °C, while in Pakistan a new and more devastating flooding, as in 2010, caused 400 deaths.
|In Jerusalem, where the snow is a rare phenomenon, this year there has been more abundant snowfall ever.|
|In Italy, the tornado has always been a little-known phenomenon, but lately some tornado of some importance have become common in Apulia and in the Po Valley.|
|Never so many fires had affected Russia, with a 2010 summer hottest ever.|
|In the last five years, in Britain we can count at least three extreme events, with an exceptionally dry 2011 and a particularly rainy 2012, which caused serious flooding.|
|In the last 10 years in Romania there were floods of biblical proportions, like that of 2006.|
|In Australia, the fires have a yearly basis, but those occurred from 2009 to the present day have been the most devastating, with the last summer officially became “the warmest ever,” while a tsunami of sand has also been recorded.|
|In the U.S., drought has always been a natural phenomenon, but the last episodes occurred between 2010 and 2012 are to be counted among the worst ever recorded.|
There is no town or city that annually will not record a climatic anomaly albeit brief, as exceptional waves of heat or cold, or wind or rain of extraordinary scope. Weather events which, by their scope and unpredictability, take us unprepared and inevitably cause damage.
Once, we were accustomed to configure a nation basing on its geographic location, from which its climate depended on. And in this it was logical to assume that an African community or country, for instance, was not used and designed to withstand snow and floods, as well as a country to the polar extremes can’t withstand heat and drought. Climate geography, for one reason or another, has changed and we are now all in the same boat, even if not yet trained and equipped for such different or extreme events.
Many countries in the U.S. are accustomed to tornado and over the years have acquired a culture and preparation that in other countries, where tornadoes are non-existent, there is not, as well as different countries are accustomed to heavy snowfall and extreme cold, or as Japan is prepared in earthquakes theme. The opposite happens, of course, in other countries with respect to different climatic and environmental situations. As just one example, if here in Naples a tornado came, half the city would be razed to the ground, or if it snowed so much and long, most of the houses (with horizontal roof) would be at grave risk of collapse.
According to the International Institute for Climate & Society at Columbia University study, the “vagaries of the climate” will increase over the next ten years. Temperatures will rise again and these weather phenomena are determined both by natural and human beings causes. Finally, according to a study of the organization Australian Global Carbon Project, the temperature increase that we should expect by the end of the century, if things do not change, is between 4 and 6 ° C, well above the 2 ° C which, according to most climatologists, already represent the critical threshold beyond which it is difficult to predict what others changes we can assist.
