Con base en el análisis de estudios realizados por diversos ingenieros, abogados y políticos estadounidenses, demostramos que desde principios del siglo XX se sabía de esta variabilidad. Específicamente se busca explicar el significado y consecuencias que tuvo el tema de la variabilidad en la minuta 319, firmada por la Comisión Internacional de Límites y Aguas (International Border and Water Commission), donde por primera ocasión se contempla de manera explícita el cambio climático, dado que diversos sectores han insistido en profundizar en el tema de definir &#8220;sequía extraordinaria&#8221;, argumentando que una cuota fija a México no tomó en cuenta el factor de cambio climático.]]></p></abstract>

Based on the analysis of studies carried out by various US engineers, lawyers and politicians, we have shown that since the beginning of the 20th century this variability was known. Specifically, it seeks to explain the meaning and consequences of the issue of variability in minutes 319, signed by the International Boundary and Water Commission, where for the first time, since several sectors have insisted on deepening the issue of defining &#8220;extraordinary gear&#8221;, arguing that a fixed quota for Mexico did not take into account the climate change factor.]]></p></abstract>
