Mexico City. Facing Mexico, at least, 12 Consequences of Climate ChangeAccording to the 2021 report on climate change, there is a possibility of extreme drought, rising sea level on the coast, lack of oxygen in the sea, heavy rains, river flow, dust storms and fires. United Nations (UN).
One of the warnings relates to the volume of water seriously depleted in oxygen, primarily in the Gulf of Mexico, which means a loss of the ability to support biomass, the diversity of animals, plants, algae and microorganisms.
High concentrations of carbon in the Gulf of Mexico, combined with indications of marine acidity, reduce the buffering capacity of marine salts, which is another effect of climate change.
One of the effects of this phenomenon is that it destroys coral reefs. The United Nations has warned that between 2009 and 2020, 14% of the world’s coral has been lost. The worst affected areas are Mexico, the Caribbean and the Pacific.
In areas where data is highly reliable, long-term coral losses range from 5% in East Asia to 95% in the Eastern Tropical Pacific. In Australia, the Caribbean, the tropical East Pacific and South Asia, more than 75% of the areas that have been under repeated surveillance for more than 15 years and have experienced major problems have fully recovered. Failed to do and regain their previous status. Mess “, claims the United Nations
According to the United Nations, another effect of climate change is the rapid submergence of seabed in the Gulf of Mexico.
However, cities such as the Mexican capital have sought to reduce its impact. Environmental pollutionThe United Nations has warned that air quality will have an impact on the climate, including strong regional changes.
one of the Effects of pollution This is a rising temperature and the so-called heat islands are growing in cities.
According to the United Nations, rainfall irregularities are the order of the day, as hurricanes in recent years have been compared to the extremes recorded over the centuries and increasing in frequency. Heavy rains have mainly affected the country’s southeast and the Gulf of Mexico basin, but in recent years the country has not been spared the severe effects of hurricanes in the North Pacific, and the upward trend is expected to continue.
Included in this, United Nations It has been warned that Mexico will face constant flooding due to the effects of heavy rains. An example of this is what happened in Hedalgo with the overflow of the Tola River, due to the large amount of water that did not fit in the dams in the area.
Drought is another trend that has intensified in recent years. Last July, for example, 70 percent of the country experienced the worst drought in recent years and 20 percent experienced severe drought.
The United Nations estimates that this trend will continue in the coming years and will intensify in the north, the United States and Canada.
In all of North America, it is very possible that the upward trend in temperature will continue, with an increase of 0.5 degrees per decade, “the United Nations said.
Soil moisture loss is more widespread in North America, mainly in Mexico. In the years to come, drought will be another companion in the states of the country.
From 1948 to 2010, summer rainfall trends in the southwest and northwest of the country were significantly negative. Experts suggest that confirmation of this trend began in the 1970s.
But sea levels are also rising off the coast of Mexico. Although this phenomenon is found in many parts of the world, in Mexico it is most clearly seen on the beaches of Veracruz, where residents see how some of their beaches disappear from one day to the next. Their livelihood with them.
Extreme heat, pollution and lack of rainfall cause more forest fires, mainly in the west and northwest of the country.
According to Greenpeace, this year Mexico experienced one of its worst years in terms of fires, leaving important sources of carbon dioxide in addition to forest damage, which accelerated climate change.
Warm days increase year by year, according to the United Nations, especially in northern Mexico, but as a natural effect, cold days are fewer, though more severe.
This is another part of climate change. Wind speed and frequency In Mexico, it has been declining for the past four decades.
But droughts and droughts bring with them another trend: dust storms that, according to the United Nations, are on the rise, mainly in the southwest of the country, and could spread to other parts of the country. ۔
According to the United Nations, dust storms and desert dust loads are likely to decrease in most coastal and coastal areas, but will increase in Mexico and the southwestern United States.
