Climate Changes ..nonsese or the real threat?

Many people including for example our previous president Vaclav Klaus think that global warming and climate changes are nonsense. But scientists say something different and I think that they are right because I can see these changes on my own.

The first consequences of climate change can already be seen in Europe and worldwide. And scientists say that it is going to intensify in the coming decades. Temperatures are rising, rainfall patterns are shifting, glaciers are melting, sea levels are getting higher and extreme weather resulting in hazards such as floods and droughts is becoming more common.

Everyone could notice these changes during this year. Winter was long and cold while summer was very dry. It was really interesting to observe the end of this winter. At the beginning of one week it was about 3 degrees below zero and at the end of the week we were wearing T-shirts! Moreover, first weeks of summer holidays were in the sign of changes. Half a week there was a very hot weather while second half of the week there were so heavy rains that they caused floods. It repeated three times during one month. Isn’t it strange? 

Extreme weather events pose a direct risk to the health and safety of people. Damage to property and infrastructure imposes heavy costs on society and the economy. Flooding in the EU killed more than 2 500 people and affected more than 5.5 million over the period 1980-2011 and caused direct economic losses of more than €90 billion.

Moreover, climate change is happening so fast that many plant and animal species will struggle to cope. Warming would put as many as 20-30% of plant and animal species at increased risk of extinction.

Well, what do you think? Is it nonsense or the real threat??
