The planets are continually changing; Although this process happens quite slowly and goes unnoticed with the naked eye. However, for years, our planet has presented some changes that we can observe and notice. Will they go further for decades to come?
The state of the environment is no longer an accessory and secondary issue on the political agendas around the world. The constant warnings of the environmental groups and their alarm message have had the desired effect: to make the population, and the leaders, aware of taking action on the matter.
But despite the advances towards sustainability in all fields, undeniable, these are not enough yet. And the forceful consequences that the UN warned about last year could come true.
Below, we compile the most important predictions about what Earth will be like in 2050, made by different scientific teams.
The temperature will increase from two to three degrees
The gaseous pollutants, mainly responsible. Taking into account the current trend in emissions, the UN IPCC estimates that this increase in temperature is almost inevitable and that, at best, it will be one and a half degrees higher than now.
However, this problem would not end here. Other, longer-term studies have even raised the figure to seven and a half degrees by 2070. What is the same, if met, we will have temperatures typical of the Sahara?
The Arctic will run out of ice during the summer
From heat to ice, two very connected elements. In fact, perhaps the best-known aspect of climate change is the melting of glaciers. An event that, in numbers, scares almost more: the poles lose 300 gigatons of ice each year. Will they ever completely melt? ¿ What then?
To learn about its evolution, several scientific institutes have joined together to carry out exhaustive research on the future of the Arctic. Led by Dirk Notz, professor at the University of Hamburg, Germany, they propose 50 possible scenarios depending on the amount of polluting emissions that will be carried out in the coming years. Its conclusion is quite disturbing: the Arctic will run out of ice in the summer months from 2050. Even earlier, according to Notz.
What we now know as large blocks of ice will transform into one more sea and will freeze again, predictably, in the colder months.
The sea level will increase half a meter
What about all this amount of melted ice? That turns into water. The current level is estimated to have increased by half a meter by 2050.
Apparently, this amount is not too much and can seem harmless. However, the report that provides these data points out that hundreds of millions of families will lose their home, buried by water. In this context, Indonesia and India will be two of the countries most affected by the floods; leading to an unprecedented climate refugee crisis.
More floods, droughts and storms in the Indian Ocean
As if the floods that devastate entire cities are not enough, India and other areas near the Indian Ocean could also suffer an ancient pattern of storms, floods and sudden droughts, similar to that of the tropical Pacific. The phenomenon, known as El Niño, does not yet have a clear cause.
Pedro DiNezio, a climate scientist at the University of Texas Austin Institute of Geophysics and lead author of this study, warns that global warming could trigger it again.
More plastic than fish in the sea
To the previous situations, we must add, in addition, the pollution of the oceans, which is not small. The Ellen MacArthur Foundation believes that in 2050 there will be more plastic than fish in the sea, a surprise at least worrying.
For some years, environmental organizations have been warning of the huge amount of waste floating in the oceans, forming gigantic islands of garbage and killing animals and flowers, in addition to damaging our health with microplastics. Thus, there are other studies that suggest that by 2100, 60% of fish may be extinct due to the contamination in which they live.
Is there a solution or is it late?
These five predictions of what Earth will be like in 2050 are advance ideas of events that have not yet happened. Some experts assure that they will be fulfilled, while others are somewhat more optimistic about it and consider that we can still reverse the problem if we act now.
That citizens are more aware and careful with our consumption and change our habits for more sustainable ones is fine, for example, limiting the use of plastics. But the equation also requires – and, above all – the collaboration of large companies and governments to transform the most polluting industries.
Betting on renewable energies and sustainable solutions, in addition to cleaning nature from garbage, we will take care of our planet and prevent these situations from materializing.
