How carbon dioxide is important to us as aquarists and concerned
citizens. Joshua Wiegert | By now, the concept of climate change
is taken as fact by all but a handful of scientists. But there
are a few holdouts to the concept of climate change, just as a
handful of individuals hold tight to the belief that the Earth
is flat, that Loch Ness holds a giant monster, and that the
growth on their back is nothing to worry about. Unfortunately, a
cold look at the evidence (or is that a warm look?) shows that
climate change is undeniable. Climate change is not a new
concept at all. Indeed, Svante Arrhenius suggested that
increased carbon emissions may result in a greenhouse-like
warming of the earth (in fact, he coined the term “greenhouse
effect”). If his name sounds familiar, it should be to all
aquarists. He is the guy who figured out what makes acids and
bases – and if this sounds ancient, it was. Arrhenius was born
in 1859 and proposed his greenhouse theory back in 1896. That's
