Last Wednesday, World Environment Day was celebrated. Campaigns against the consumption of plastic were launched from different corners of the world, in favor of a circular and sustainable economy and, in short, respect for the environment. It is a reality that citizens, platforms, associations and NGOs give more and more importance to respect for the environment and sustainability.
But sustainability is not a matter of a day or a week. This issue deserves much more attention than can be received in a single day. In this sense, there are several theories about the importance of reversing from and to the effects that cause climate change.
In the opinion of some experts we are very close to the point of no return, that is, there is the possibility that one day, sooner than later, we can live the beginning of the end. And is that the changes produced by humans on our planet, especially in the s. XX, they are transforming some of the essential elements for the survival of the planet, or of life on it.
Specifically, the document published in the magazine Nature It indicates a term of action of 3 years. Yes, you have read correctly, 3 years! or what is the same, by 2022 we must have managed to reverse the production and consumption model, the energies used by industries in the societies of the world.
This document, signed by important and prestigious scientists and diplomats, including the anthropologist and economist Christian Figueres, secretary of the United Nations Convention on climate change, warns of the little reaction time we have and the important steps to take.
It is necessary to reduce CO2 emissions immediately, that is, in 2020 we will aim to reduce the average temperature of the planet by half a degree. Experts have recorded record temperatures year after year, today the temperature is at 115.000 years ago (it was pre-glacier) where the sea level reached 6 meters more than today.
Among the skeptics and 'ecophobes' extends the mantra that sometimes it is also colder or that temperatures are softening depending on which locations. Nothing is further from this. Today there are patterns fully demonstrated and verifiable by anyone.
The poles are melting. But not only the outermost parts melt, but today entire glaciers disappear. According to satellite measurements, ice masses are reduced by 100 cubic km each year in Antarctica (recorded since 2002). In addition, due to the warming of the oceans, sea ice is also disappearing. Glaciers, meanwhile, are also reduced in size every year.
Stress in marine ecosystems is causing many species to see their standard of living diminished, many plant and animal species have disappeared and sea level does not stop growing.
The increase in extreme weather incidents (hurricanes, floods, tsunamis, fires, droughts ...) is alarming, both in terms of intensities and locations, as natural disasters are occurring in places that had never suffered before.
According to the researchers, there are keys to solving these problems:
-Energy: ensure that by 2050 30% of the energy is reusable.
-Infrastructure: Decarbonize buildings and infrastructure by 2050
-Transport: Ensure that 15% of all new vehicles are electric, increase the efficiency for heavy vehicle fuels by 20% and reduce emissions per km in the aviation sector by 20%.
- Land use: Reduce deforestation and associated emissions.
-Industry: Plan to reduce emissions by half by 2050.
-Finance: The financial sector mobilizes millions of euros in green bonds and is reconsidering a change of direction to combat climate change.
With this panorama, and maintaining an individual vision of the mechanisms to reverse these processes, there are several key elements so that in the coming years we will have solutions that make us get out of that alarming countdown.
There are also a series of concrete actions, raised so that among all citizens we also have the possibility of contributing towards change. Among the most important: consume renewable energy, live without a car, avoid airplanes, diets based on vegetables and legumes and not have more than one child.
