Climate change today is on everyone's lips, even if with a "slight" delay: for too many years they have been ignored, considered only a catastrophic theory, a problem of future generations. The last extraordinary meeting in Katowice for COP24 reveals a certain urgency in doing something globally, but it seems that even this meeting has managed to extract something effective and immediate to save the planet.
Drought anomalies of drought in northern Europe, polar ice caps that fracture for the first time after millennia, hurricanes and other climatic phenomena of unpredictable violence: these - along with many others - are the alarm bells that confirm as something very grave is happening to our planet.
The subject is now so important that it finally arrived on TV in the prime time slot, specifically in the Le Iene show. During an episode aired in October 2018, Nadia Toffa interviewed Simone Molteni (scientific director of LifeGate) about climate change, bringing out interesting (and rather worrying) aspects that probably the general public ignored. Let's see some.
About 150 years ago, with the start of the industrial revolution, the Earth's temperature began to rise at a pace never seen before. The massive use of fossil fuels has on the one hand given a strong impetus to the technological and economic development of humanity, but on the other hand has generated a very high price in terms of environmental destruction.
That huge amount of energy has in fact undermined the balance of the planet leading to drastic changes: if you think about it, we are realizing it in person, even in Italy!
Thunderstorms, typhoons and water bombs in typical tropical style are in fact making their entry into our normality; we witness the free migration of animals from tropical areas, which carry diseases and devastation to which we and our ecosystems are not prepared; the glaciers are disappearing, and within a century there will probably be no more in the Alps below 3,600 meters.
The costs will also pay a very high price. The Mediterranean Sea could grow by a meter within the century, covering enormous areas of the peninsula: certainly not only Venice (the first city we usually think of in these cases), but also Rome, part of Puglia and Tuscany and the whole Plain Padana up to Milan. People all over the world will be forced to move due to flooded or desertified areas, generating an estimated volume of 150 million climate migrants.
We are therefore one step away from reaching the "point of no return": according to the UN, the warming of 1.5 degrees that we expected in a century could take place in 12 years.
Unfortunately, the Kyoto Protocol and the subsequent Paris Agreements are not giving the desired results. There are many quibbles, many loopholes to cling to not submit to the rigid (but necessary) rules established at the international level. We have reached a historical moment in which we can not therefore rely entirely on institutions, but we must be the first to worry about our future.
The virtuous actions are the same that were recommended decades ago, but that few seem to have put into practice: avoid using the car, do not abuse the domestic heating and a thousand other small daily measures that, if multiplied by large amounts of citizens, they can make the difference.
Moreover, today, compared to some years ago, there are alternative and green solutions such as hybrid cars; or, because the house is a huge source of energy expenditure, you can easily decide to feed it with renewable energy: to do so it takes 5 minutes online and does not cost more.
In short, if on the one hand there are all the conditions for catastrophic consequences, on the other, today we have the technological know-how and the right services to try and stop them. The transition to renewable energy is the only way to go, and today is no longer just accessible to a wealthy society, but it is absolutely within the reach of ordinary citizens, the only ones who can make the difference given the inertia of governments.
