Climate change in Mexico is expected to have widespread impacts: with significant decreases in precipitation and increases in temperatures. This will put pressure on the economy, people and the biodiversity of many parts of the country, which have largely arid or hot climates. Already climate change has impacted agriculture,[1] biodiversity, farmer livelihoods, and migration,[2][3] as well as water, health, air pollution, traffic disruption from floods, and housing vulnerability to landslides.[4][5]
Altered precipitation patterns and warming temperatures have led to economic insecurity in Mexico, particularly for smallholder farmers who grow Mexico's economically and culturally important crops: maize and coffee. Climate change impacts are especially severe in Mexico City, due to increases in air pollution.[6][clarification needed] Ecological impacts of climate change within Mexico include reductions in landscape connectivity and shifting migratory patterns of animals. Furthermore, climate change in Mexico is tied to worldwide trade and economic processes which relate directly to global food security.[clarification needed]
