Mexico City has reached temperatures of 31 degrees, which would have been unimaginable in the past, however, since last April 17, the Secretariat of the Comprehensive Administration of Risks and Civil Protection Activate yellow alert due to heat wave which will be available in the next few days.

Which is that for several years, it’s been getting hotter in the metropolitan metropolis and today we’re going to show you how science interprets these temperatures and what direction it’s going to be in the future.
Why is it so hot in CDMX?
According to the United Nations system in Mexico, greenhouse gas concentrations have reached their highest level in two million years.
This has resulted in the Earth’s temperature now 1.1°C warmer than it was at the end of the 19th century, making the last decade the warmest on record, and thus our urban capital suffered devastation.
Similarly, the World Meteorological Organization (World Meteorological Organization) It shows that carbon dioxide (CO2) increased by 147%, methane (CH4) by 259%, and nitrous oxide (N2O) by 123%. These increases make climate change more severe, temperatures rise and extreme weather events multiply.
“The future well-being of mankind is at stake”, WMO Secretary-General Petteri Taalas confirmed it on Monday.
temperature rise trend
Report from NASA and the National Oceanic and Atmospheric Administration (NOAA for its English acronym) detail that the temperature of the Earth’s surface and oceans over the past year was 58.5 degrees Fahrenheit, which means 33.5 degrees Fahrenheit above the twentieth century average.
in this way, 2021 was the sixth hottest year since records began in 1880, Slightly higher than 2018 and surpassed in 2015, 2016, 2017, 2019 and 2020.
So far the two warmest years have been 2015 and 2020, But experts cautioned that this does not mean breaking the upward trend in 2021, but on the contrary.
That last year was one of the hottest years despite its record La Niña phenomenon, Which means cooler Pacific waters and lower temperatures.
“Even with La Niña, being among the hottest years allows us to see that 2021 has followed the pattern of the last decade on the planet,” Sepulveda stressed.
Edel Sepulveda, a scientist at NASA’s Goddard Space Flight Center, He explained to EFE that global warming is caused by the emission of gases into the atmosphere such as carbon dioxide that trap radiation and produce the so-called greenhouse effect on Earth.
“There is a broad consensus that humans are causing global warming and there is no doubt about it. The effects of this warming are not in the future, but are already recognizable.” .
According to the world, High temperature “Main Ingredient” for heat waves Like the ones the US experienced last summer, so did wildfires and droughts.
Higher temperatures also generate more vapor in the atmosphere which leads to heavy rains and floods. Like what happened in Germany, or sea level rise due to the melting of the poles.
NASA warned in its report that The amount of heat stored in the upper levels of the ocean hit a record high in 2021, surpassing the 2020 mark.
“Greenhouse gases will be in the atmosphere for decades, so the important thing is that action can be taken in the coming years,” The expert is finished.
