Effects of global warming in Mexico
vulnerable areas
Climate and vegetation
warmer climate than today, mainly in the north of the country. The
Humidity may decrease, resulting in drought due to evaporation.
Decrease temperate regions and the amount of rainfall is reduced by the
central region.
Conifer forests and oak suffer an increase in temperature of 2 ° C
and a decrease of 10% in precipitation. By contrast, the tropical rain forests
They will be favored, with a decrease in temperature of 2 ° C.
Northwest and north
from Mexico.
mountainous systems of the country.
Farming
Global warming affects vegetation, mainly in production
food, especially in agricultural regions temporary. The surface
suitable for the cultivation of maize would be reduced from 40 to 25 percent.
Super fi sown agricultural surface

temporal).
Water
Water availability will decrease by 10% by 2020 compared to 2000 due to
the decrease in rainfall.
Mainly central and northwestern
from the country.
coastal areas
The sea level rise will inundate part of the Gulf of Mexico coast,
the Yucatan peninsula and the northeast coast. Grasslands and lands
Agricultural be contaminated with the salinity of the sea.
Rising sea disrupt ecosystems and coastal lagoons
will cause irreversible damage to biodiversity.
With rising sea temperature it is likely as
Consequently, hurricanes reach higher categories

All coastal regions,
mainly in Veracruz,
Tabasco, Nayarit, Chiapas and
Yucatan Peninsula.
Population
The consequences are seen mainly in large cities. There will be
Water shortages caused by the reduced rainfall and decreased
in recharging aquifers also they are presented floods
caused by extreme rainfall.
A direct effect on health is the "heat stroke" that prevents people
release the excess heat when under the sun. In the northwestern states of
country will increase mortality from this cause.
A temperature increase may cause an increase in
concentrations of ozone in the atmosphere of cities. In crowded this

on the health of the population and the destruction of the nearby woods.
