Max temperatures MCentral America - migration from climate-heat
Hello Eric,
It seems clear that climate is causing much of the migration from Central America into Mexico and then into the United States in recent years.
Climate is also responsible for temperature rise in the Sonoran desert, especially impacting the USA southern border state of Arizona and Mexican northern border states of Baja California and Sonora.
Children with disability, and children who become disabled by the trauma of migration, are thus impacted, with their lives disrupted and school attendance disrupted or eliminated. See graphs below, but these thoughts are just thrown together and need more careful wording, especially as to issues around walking and/or riding to school by children and youth with disabilities, which is a concern we are working on through a report on USA & Mexico border state school transportation issues.
