Climate change
The weather has a permanent influence on our lives. The sky is often the first thing we look when we wake up in the morning. Pressure and humidity affect our body and mood; who has never said “today I am depressed: I should probably blame it on the rain?”. At least once a day most of us want to see or hear a weather forecast and ever since we were born we are used to season cycles that regulate the biologic cycles of all living beings. Popular sayings have been invented about the weather that often sound silly; but the sentence “seasons no longer are the way they used to be”, no matter how old a complaint, because Virgil said it 2000 years ago, has never seemed so a propos as in the past years. In the last years, in fact, we have had springs that seemed like summers, winters that seemed like autumns and meanwhile the media keep telling us about greenhouse gasses and global warming, environmentalists give catastrophic forecasts for the future, while scientists and politicians are obviously trying to calm the alarmism. In all this great confusion it is always us “normal people”, to be left without any clear ideas and so it is our duty to at least try to understand a little bit better the way how things actually stand.
