Ironically, where I live in Canada, I've been noticing more and more monarchs (and their close cousin the viceroy) each year in my gardens and the milkweed fields. Perhaps some change in environment/temperature is causing this. Or maybe they just like free healthcare.

It stands to reason that, if temperatures are rising, insects will benefit in cold climates such as yours.

I feel the need to point out that global warming doesn't warm every area and is calculated as a global average increase in temperature. Some areas may actually get colder due to the environment changes, not warmer.

Interestingly enough however, Canada are one of those areas that is getting warmer more than average.
