Hi Mauricio, This is just how I would write the same paragraph. Great work ((-:    -un saludo

Climate change is real. How can it be possible for some people to deny its existence. A few days ago I came across a magazine by chance that had been forgotten amongst some books. I read in it an article about climate change. I was surprised to read that Chile is amongst one of the five countries most affected by climate change. There is a lot of evidence about the changing climate around the world. Greenland had its highest temperature ever recorded during the past April. In the Arctic the ice cap has shrunk significantly over the last three or four decades. China in the past year has suffered one of its coldest winters in fifty years. In our country Chile, over the past three or four decades it can be seen how the Atacama desert has been gaining ground and how in the south of Chile, where rainfall levels are amongst the highest on the planet, there has been a gradual decrease in these rainfall levels. Perhaps the most important feature of climate change are extreme events. We have faced at times, long periods of drought, at other times torrential rains. We have also had extreme temperatures, for example this spring we had the highest ever recorded spring temperature of 38 degrees Celsius. The most likely cause of this change lies in human actions. So again I wonder, how can it be possible to deny climate change when there is so much evidence to prove its existence? I have only one answer: “economic interests” (I am convinced that certain “economic interests” don't care about respecting nature or with respecting the earth). 

Could someone take a look at my short text about Climate Change?
