Contaminated water and drought in CDMX?: This is the degree of scarcity in the capital

In the middle of the dry season, Mexico City is going through a water crisis and, in addition to this, residents of the Benito Juárez mayor’s office have reported the presence of contaminated water in neighborhoods such as Christmas Eve, Del Valle Centro, Del Valle Norte and the Nápoles neighborhood.

Currently, the Mexican capital maintains the degree of severe drought (D2) according to the latest report of the Drought Monitor in Mexico (MSM) of the National Water Commission (Conagua) which indicates that at the end of March, the most affected area is the center-south, with 84.4 percent drought.

At the same time, this Sunday, April 14, CDMX broke a historical record for high temperatures, reporting, for the first time, 32.9 degrees at the Tacubaya Observatory and exceeding the 32 degrees reported on April 14, 1998.

Another of the hottest areas this afternoon was the Mexico City International Airport (AICM) where 30 degrees maximum were reported.

These factors in combination combined with the Lack of rain is seriously affecting damsmainly to the Cutzamala System, which has caused problems in the supply of drinking water for the residents of the capital.

Global warming on the planet: Greenhouse gas emissions records are broken

Graciela Binimelis de Raga, researcher at the Micro and Mesoscale Interaction Group at the National Autonomous University of Mexico (UNAM), shared during the conference ‘State of the global climate and in Mexico that GHG emissions such as carbon dioxide (CO2) and methane (CH4), and its concentrations in the atmosphere continue to increase.

He explained that the temperature of the planet “is the result of a balance between the energy that comes from the Sun and that produced by the planet”; However, “the growing concentration of GHGs emitted by human activities, “Since the beginning of the industrial era, it has resulted in an imbalance.”

He added that the above constitutes a “radiative forcing” and is estimated from the forcing of each of the different anthropogenic components (gases, aerosol particles, clouds and changes to the surface) which results in increase in global average temperature on the surface of the world. “As emissions have continued, the planet continues to warm.”

In the case of Mexico, experts pointed out that it has been observed that the annual air temperature, until the end of 2021, has risen 1.69 degrees Celsius with respect to the beginning of the 20th century.

The increase and rate of increase in average annual air temperature are greater than the global average.

“The rate of increase in average annual temperature is heterogeneous, with higher values ​​in the north and southeast,” detailed Binimelis de Raga.

The temperature “is not homogeneous throughout the year, being higher in autumn and spring, and lower in winter and summer.”

Regarding changes observed in precipitation in this country, the researcher noted that the average annual rainfall in the territory has increased at a rate of 3.1 millimeters per month (mm/month) per century since the beginning of the 20th century.

“The change in precipitation is highly heterogeneous; has decreased in northern regions and increased in the center and south,” he commented.
