Nature, climate and weather are very complex to understand. The word „climate“ is derived from the Greek word „klinein“ which means „to slope“. Climate can be defined as the probability of deviations from average values, including the probability of extreme values. Climate does not change our weather and humans cannot control the nature. Today, we don’t know why certain things happen and we talk about as we know everything, but the truth is: we believe too often without actually knowing.
