This article, implying the demise of the unique Mexico-Canada migration, seems too pessimistic. Monarchs have shown a great degree of adaptability. There are monarchs of the western United States, resident populations in Hawaii and on Caribbean islands, and a migrating population in Australia. I am betting that even if the weather forecast for 2050 is correct, the monarchs will find a way to survive it.
