Global warming: something must be done, time is running out

If we stop the massive emission of greenhouse gases, we will be able to contain the temperature increase to the limit of two degrees by the end of the century. If, on the other hand, we do nothing and the increase in temperature, by 2100, will be 5 degrees: a catastrophic scenario for future generations.

By Gianfranco Gatta

07/29/2021 was the "Earth Overshoot Day" or rather we ran out of Earth's resources for 2021. From 29th, therefore, until the end of 2021, humanity will only increase the ecological deficit, they will consume many more resources than are renewed in nature. And our "debt" to the Earth is growing more and more.

No one would ever have bet a penny on the fact that, after the alarm launched a month ago by the World Meteorological Organization WMO, where it indicated that the global temperature is about to exceed 1-1.5 degrees, it would soon become aware of the gravity of the situation, with related measures.

Luckily it didn't happen that way. Biden, who had just taken office, immediately said he wanted to join the Paris accords, reneged by his predecessor, Trump. The recently concluded G7 and the same preliminaries as the next G20 have had and have, as a priority, the reduction of CO2 emissions.

Europe itself is deciding, starting from 2025, that by 2050 only electric cars will circulate. In two months, enormous steps have been taken, as intended, as many as had not been taken since the Kyoto Protocol of 1997.

Not only has the cultural debate we hoped for has ignited, thanks to Greta Thunberg, but a real political resolution is underway. That the resolution then turns into a fierce battle due to the resistance of various economic lobbies is part of the logic of human misery.

Car manufacturers, airlines, the cement, steel, fertilizer and aluminum industries, some states such as China and India, feel penalized by these measures and have been fighting them with all possible means since the Kyoto agreements.

The CO2 produced by human activities is the main factor of global warming. In 2020, the concentration in the atmosphere was 48% above the pre-industrial level (before 1750), thanks to the combustion of coal, oil and gas; if you add to this deforestation, the development of intensive livestock farming and the massive overbuilding after the war, you have a clear picture of the causes of global warming.

The 2011-2020 period was the hottest decade on record, with an average global temperature of 1.1ºC; human-induced warming is currently increasing at a rate of 0.2ºC per decade.

The Paris Agreement clearly says that if we stop emitting such massive greenhouse gases, we will be able to keep the temperature rise to the limit of two degrees by the end of the century.

If, on the other hand, we do nothing and continue to adopt a predatory and polluting economic model, the temperature increase, by 2100, will be 5 degrees. This would be a catastrophic scenario for future generations.

Luca Mercalli, climatologist and president of the Italian Meteorological Society says: In about thirty years, those who live in the Po Delta or in the Venetian lagoon will have to escape because they will have the sea in their living room. Also in Italy, as in many other areas of the planet, there will be climate refugees. We must cut down on the consumption of fossil fuels or we risk a catastrophe”.

To the recent disasters that have occurred in Canada, China and Germany, with hundreds of victims and thousands of missing, is added the anomaly that records spring temperatures both at the North Pole and at the South Pole.

Last but not least, the rise in temperature favors the spread of pandemics and it is reasonable to think that at Covid 19 others will follow in the years to come.

So as not to miss anything, a recent study by the French Ademe, the Agence de la transition écologique, reveals that: “The network will also be a virtual space but the pollution it produces is real. Eight emails emit as much carbon dioxide as that of a car traveling a kilometer and the email traffic of a company with 100 employees who send an average of 33 emails a day for 220 days a year, produces about 13.6 tons of carbon dioxide, like 13 round trips from Paris to New York”.

A “cultural reconversion” is needed that only the new generations can implement, bearing in mind what Einstein said: “Problems cannot be solved at the same level of knowledge that created them”, and then add: “Two things are infinite: the universe and human stupidity, but I still have doubts about the universe”.
