“Consistent with" is a very weak statement and could apply to many things. It does not even make a claim of correlation, and all us scientific logical types know correlation does not imply causation. So is the rise in CO2 emissions the culprit in causing an incipient bumblebee apocalypse? The answer is not clear when a slew of other causes from habitat loss, toxic substance pollution, and invasive species are thrown in the mix. All in all, this says a lot less than it meant to. Without a few plausible candidate mechanisms to explain how more CO2 and climate change can harm theses adaptable insects, it all remains very speculative.
