Detailed explanation-1: -Temperature is expected to increase in Mexico by 1.1–3.0 °C by 2060 and 1.3–4.8 °C by 2090. As such, scientists, including the IPCC, have classified the entire Central American region as a “climate change hot-spot” and “highly vulnerable” to climate change.

Detailed explanation-2: -Mexico faces a number of very serious environmental challenges. The provision of clean water to Mexico City, air pollution in the capital and other major cities, deforestation and erosion in rural Mexico are some of the most pressing problems.

Detailed explanation-3: -Worldwide, Mexico is responsible for emitting 1.33% of GHG worldwide.

Detailed explanation-4: -CDMX, as the city of 21 million styles itself, pumps more water from the aquifer below it than it replenishes: the city sank some 12 meters in the last century and may sink another 30 meters before hitting rock bottom. The drier land also puts buildings at greater risk for earthquake damage.

Detailed explanation-5: -Meanwhile, Mexico is exposed to a range of physical risks, including acute risks associated with floods and tropical cyclones, by virtue of the exposure to both the North Atlantic and Eastern Pacific hurricane basins, droughts, and heatwaves, and chronic risks.
