Ecologists predict impact of climate change on vulnerable species

Think that climate change isn't happening, or that the risks are overstated? You haven't been paying attention. Species that have thought that Canada was too damn cold (and who can blame them) are now finding it hospitable. This doesn't happen in one year. Or even a few. To maintain a presence and to thrive the trend needs to be long term.

And its happening.

If a dominant species can thrive in a warmer environment and wipe out other species, climate change could significantly reduce the diversity of species in our lakes as well. Less diversity could also have economic repercussions for Ontario. According to a 2010 survey of recreational fishing, anglers contributed more than $2 billion to the province’s economy.
