What will the climate be like in 2050?

December 2050. We are experiencing a new heat wave. The maximums exceed 40 degrees in Santiago, droughts increase in the center-south, while rivers overflow in the southern zone. TV Tiempo reports electrical storms, water rationing, and power outages across the country.

What will the weather be like in 2050?

The forecast does not leave anyone indifferent, but so far it is fiction “although it could be a reality if conditions don't change”, Warns the meteorologist from the University of Magallanes and lead author of the Fifth IPCC Report, Jorge Carrasco.

The weather forecast, prepared in conjunction with the TV Tiempo de TVN team, is based on the latest Report of the Intergovernmental Panel on Climate Change. The study shows that by the middle of the 21st century, temperatures will rise in Chile between one and four degrees; Rainfall will decrease between 10% and 20% in the central and southern areas of the country and will increase by up to 10% in the southern and northern areas.

CLIMATE CHANGE IS ALREADY OBSERVED

“There is already a concentration in the atmosphere of 400 particles per million volume. You know that the normal is 280 ", explains Carrasco," it is a quantity never seen in the last 800,000 years of the planet”. And it is this concentration of greenhouse gases in the atmosphere, generated by “the increase in population and industrial activity”, which causes changes in temperature and rainfall.

In fact, in Chile, the phenomenon is already noticeable, indicates the meteorologist, in the reduction of glaciers, the decrease in rainfall in the Valdivia area and the increase in temperature in the valleys and foothills. A change that will have consequences for health, nature and economic sectors such as agriculture and mining.

INCREASE RENEWABLE ENERGIES

It is difficult to stop climate change. "Although today we stopped all greenhouse gas emissions in the world, it would take 50 years to clean the atmosphere”, But the longer you wait to start cleaning the atmosphere, the more time it takes.

Realistically, shutting down all industries is impossible even to imagine. For this reason, the challenge that international organizations acquired is to ensure that the global temperature rise does not exceed two degrees in the middle of this century. "For this, large global agreements are required," says Jorge Carrasco, "to reduce fossil fuels (major causes of greenhouse gases) versus promoting renewable energy."

Responsibility also rests with the state governments, which should generate public policies that mitigate greenhouse gases by promoting green energy. They must also prepare for a future with less water, new diseases and agriculture displaced south.

And the citizens they also enter into this fight against climate change. Using the car less and using it more efficiently, reducing the duration of daily showers or turning off the light and electronic devices are simple measures that, when added, are a great support for the environment.

Nature will take years to adapt to a temperature increase of one or two degrees, although for us it is enough to regulate the air conditioning. A gesture that could be expensive, because, after all, we coexist in and with the environment.
