Instrumental observations over the last SEMARNAT
38 years show that the annual average
temperature has risen 0.6 C in average
in the Mexican territory over this period.
The historical average temperature of the
period is 20.9 C, with the observations
after 1990 being all above this average.
Over the last 10 years, the trend
indicates an intensive warming of 0.7 C.
Standardized precipitation index
Drought could intensify in the Central region,
Jalisco region and Chiapas region. Under the A2
scenario, it would be worse than that experienced
in the fifties and seventies for the first two regions.
In general, meteorological drought leads to
hydrological drought, as well as reductions in
precipitation; increases in temperature would
increase evapo-transpiration.
