Cute, adorable animals are often used to garner support for environmental causes in places that are remote. After all, it’s hard to have concern for an area that is at the opposite end of the Earth from where you live and for which you have no plans to ever see. It’s why polar bears, for example, have been used as the poster children for the rapid loss of sea ice in the Arctic ever since “global warming” became a household phrase decades ago.
Today, scientists largely agree that humans have been major players in that loss. Recently, in fact, researchers have found that neither natural climate fluctuations nor self-acceleration can explain the observed Arctic sea-ice retreat. Instead, they’ve found a strong, plausible correlation with increasing greenhouse gas concentrations — increasing as a result of human activities.
What is surprising, though, is that at the opposite end of the Earth, no such link between greenhouse gas concentrations and retreating sea ice has been found. In truth, Antarctic sea ice is actually gaining ground.
So, if we’re losing ice at one end of the planet, but gaining at the other, is there cause for concern? Continue reading →
