UN Intergovernmental Panel on climate change (IPCC) yesterday published its sixth report on the state of the planet’s climate, examining more than 14,000 articles of scientific literature and synthesizing them, in the most thorough way, in one document. Without further ado, the conclusions regarding what is happening to the Earth’s climate and its projections in the near future can only be described as follows: disaster.
In a very short time, humans have given fire to this planet. Even the cold and technical style of scientific communication could not mask the anxiety about what was happening.
Concern for the condition of the earth shines through in every chapter of this report hot and how much more it will be, how much it will be polar ice has melted and how much will melt in the coming years, how many areas of the earth will experience drought, storms, floods, fires until they are no longer habitable.
A long and painful catalogue horror the only undeniable cause of which is us, men. “AND firm that human influence has warmed the atmosphere, oceans and earth”: this is the beginning of the report and at the same time expounds the main theme. It is humans who are causing all this. In contrast to previous IPCC reports, for the first time, human responsibility is “clear”.
It may seem like a paradox, but if we want to find good news throughout the document, it lies precisely in that adjective: firm. Without uncertainty, clearly and beyond doubt, today we know that global warming this is caused by human activity.
Whether this is due to geological cycles or variations in solar activity, or due to many imaginative causes beyond our actions, tell us about denier in recent decades, things would have been much worse. The fact that it depends on us is good news: it means we can fix it. Starting from the conference next November on climate change United Nations (Police26) where Italy can and must do everything possible to ensure that the resolutions adopted are more effective than in the past.
Of course the pace maintained in recent decades is no longer tolerable. To ensure its effectiveness, just look at the concentration CO2 in the atmosphere. This is significant data, similar to the number of deaths per year Covid. As long as it doesn’t decrease, it means the solution taken is ineffective. The same thing happens with global warming: as long as CO2 continues to rise, this means we are not doing what is necessary. In the decade 1990 to 2000, CO2 in the atmosphere the average increase was 1.5 ppm (parts per million) per year, from 2000 to 2010 it increased by 2 ppm per year and from 2010 to 2020 around 2.5 ppm per year. It seems to be a trend disinterest completely of all our resolutions. It is clear that use fossil fuels it should no longer be tolerated. But this path, however unavoidable, can take too long. And time is what we lack.
For this reason, I again propose that planting be carried out in sufficient quantities tree (which removes CO2 from the atmosphere) is a fundamental solution. We will have to plant a trillion trees (perhaps fewer) and it will take years, perhaps decades, for the results to become apparent, but we are confident that the results will be realized.
Decades are not the expected time politicalI understand, but we have no serious alternative if we want to reduce the impact of global warming on the lives of billions of people. Let’s propose it firmly Glasgow: that every country in the world plants its own trees. A miracle happened.
We won the 100 meters at the Olympics, invited 200 countries to plant one trillion trees it certainly won’t get any harder.
