The alarm comes from the fifth report on climate change, sets up by the United Nations and developed by 2000 scientists.
The study shows a dramatic picture of the climate chaos produced by the use of coal and oil, and deforestation: it is “virtually certain”, say the experts, that the cold and extreme heat, floods, tropical cyclones will increase.
The Italian head of WWF’s climate department said “Since 1990 the price paid for climate change continues to grow. In Durban, where, in a month the responsible of world government you will meet hopefully a new strategy on climate protection will be set”.
Also numbers show how during the 2011 climate disasters have increased: global temperatures have set a new record, heat waves have crippled Russia, floods have killed 2.000 people in Pakistan and India, a dust storm hit Beijing stifling 250 million people. And if it is not enough, Bangkok was flooded under water, hunger and drought have devastated the Horn of Africa, Hurricane Irene have mostly reached New York.
According to the report the increased energy involved in the atmosphere produced by the growth of Co2 emissions will aggravate these problems. If the use of fossil fuels and deforestation will not stop, the heat waves which in 2003 caused 70.000 deaths in Europe will become more frequent by 2050.
The temperature will be at least 3 degrees higher than the maximum temperature in 2050 and by 2100 more than 5 degrees; arid and semi-arid areas in Africa will expand by at least 5-8 per cent, we will lose up to 80 percent of the Amazon rain forest, the taiga of China, the Siberian tundra and tundra Canada will be seriously affected, the North Pole will soon become navigable in the summer, the world’s population subjected to increasing water stress will pass from one billion to 3 billion today.
“This devastation can still be avoided if we will invest on renewable energy and energy efficiency,” says Vincent Ferrara, climatologist Enea. “It is a passage complex but can be started immediately at no cost: it would be enough to close the incentives, about $ 400 billion a year, that, globally, still finance fossil fuels”.
We can not just count the victims of the climate changes without reacting.
