In the previous issue of Phoresta News we talked about the web site of the US National Academies of Sciences, Engineering and Medicine (NASEM) that analyzes the climate change from all points of view.


It is a complex and long report in which it is easy to get lost because the phenomenon is extremely diversified. For clarity, the report is divided into four chapters. The title of the first chapter is ‘Understanding the Climate System’. In this part it is observed that the earth climate is changing and that human activities make a decisive contribution to this change. Is there scientific evidence and proofs of this? Now in abundance: from the decline of  Arctic sea ice, to the reduction of the snow cover in the northern hemisphere up to the rise of the average sea level. And let us move on to the second point: how to assess and adapt to climate impacts? Here the answer is more difficult because the rise of temperatures and the change of the rain patters are altering the life cycle of many animals and plants. In addition, abrupt climate changes – called turning points – could already be underway. Then a possible solution could be the one indicated in chapter three: “Limiting future climate change”. There seems to be only one way: to take measures to reduce emissions of CO2 and other greenhouse gases. In practice: energy could be used more efficiently by switching to fuels that produce less greenhouse gases and by capturing emissions before they enter the atmosphere. What are these clean energies? We know them: solar, wind, geothermal and hydroelectric.

Finally, a fifth point that for us is extremely important: to inform people about decisions that refer to the climate. We need to understand the needs and requirements of individual people and involve them in the choices that are made in relation to the climate. Phoresta News tries to give its contribution to this aspect. Each of the four mentioned points is subject to further investigation. Perhaps the battle is still at the beginning, but it can be won, with the help everyone. Certainly the research of NASEM is a useful starting point.
