A letter in the latest Science by P.E. Hulme argued that "it even more important for governments to design robust policy and regulatory frameworks to combat both the current and potential future threats of biological invasions" under climate change for a couple of reasons:
1. "The spread rates of alien invasive species in terrestrial and marine ecosystems are between 20 and 30 times as high as the maximum velocities of climate change."
2. "the range expansions of alien invasive species are facilitated by increasing human trade, transport, and travel."
