Environment and climate

We live in a climate that is defined as temperate, meaning that it changes every hour of the day and from day to day. Near the equator, it is different. I have lived in the Philippines where the temperature does not vary much around twenty-six degrees Celsius, except during typhoons. Our planet offers all possible climates, between the two cold poles. Each year, the northern hemisphere has its seasons in opposition to the southern hemisphere. Every day, our noon corresponds to the midnight of China and the opposite. In short, the climate changes all the time on our blue planet. So why are we so eager to fight against this climate change? Why has this issue become the main motivation for the election of the political party that wants to govern our country? Why do we believe that the climate is changing so much that we have to do everything we can to stop these changes? Professor Lu's theory from the University of Waterloo ON Canada answers these questions.
