On a three-day trade mission to Mexico, California governor Jerry Brown talked most frequently about climate change and immigration, and spoke passionately about the link between the two, according to the Wall Street Journal.

“We can see how some are fearful of children walking across the border,” Brown said at the signing of a voluntary climate-change agreement with Mexico’s Ministry of Environment and Natural Resources, according to the Journal. “What will they think when millions of people are driven north from the parched landscapes of a world degraded by intensifying climate change?”


Brown reportedly spoke of California’s relationship with Mexico as older than the one his state has with the “government in Washington.” Brown pledged to do whatever he could do to aid the Central American unaccompanied alien children arriving in his state and proclaimed his support for additional shelters for the illegal-immigrant children in California.
