The signal of how the struggle to avoid catastrophic changes in the climate and the environment will still be long and difficult comes from the hatred with which some politicians and journalists commented on the initiative of Greta Thunberg.

The suspicions immediately launched due to its being “different”, due to the apparent ease with which it managed to mobilize crowds of boys around the world, even to get the support of Pope Francis. Everything confirms that there is no better blind than those who do not want to see.

Greta and the scientists launch the alarm

Yet it is not only the young Swedish activist who reminds us that the time to act is now if we want to avoid devastating consequences, even worse than the increasingly “extreme” climate of the last two decades. The same NASA researchers have recently confirmed the accuracy of the data obtained on rapid global warming, despite some like Donald Trump keep saying it's all a farce.

The threat of global warming

If we fail to slow down the ongoing process, in the next 50-60 years the water temperature in the upper layer (the first 2,000 meters) of the oceans will increase by almost 0.8 degrees Celsius and this will lead to irreversible consequences, with all due respect of those who do not want to see the catastrophe coming. First, sea levels will increase by 30 centimeters for thermal expansion, secondly, melting glaciers will further increase the ocean level by another 20-25 centimeters.

With the heat the height of the seas rises

Half an meter more than the height of the seas means that most of the coastal areas will end up submerged. Moreover, at the borders between land and water, storms, hurricanes and extreme rains will become more frequent and more violent. Not convinced yet? Then know that from 2003 to 2017 NASA researchers have measured the temperature of the air in contact with the surface of the sea, on the earth and with the help of the Aqua satellite, carrying the Airs (Atmospheric infrared sounder) probe.

NASA data confirm the fears

The data were then compared with the results of the analysis of surface temperature anomalies conducted by the Goddard Institute of Space Research. It has been noted that the data sets correspond to each other: the temperature of the earth's surface has increased throughout the world in the last 15 years, the hottest years of the observed fifteen years were, in ascending order, the years 2016, 2017 and 2015.

A little too much to be a coincidence, a plot or some mysterious climate manipulation of “aliens” or more or less devious secret services, don't you think? So all that remains is to decide: change our way of life, using technology to safeguard the climate and the environment, or meet a scenario like the one imagined by Hollywoon in The Day After Tomorrow.
