Four Unusual Horsemen – Weird Consequences of Climate Change

While most of us can intuitively understand the relationship between a hotter planet and more intense tropical storms, droughts, forest fires and glacial melting, some of the effects of a hot, high carbon atmosphere are less tangible. A cursory glance at the geological record reveals that it doesn’t take much to upset the fine balance of processes that drive the climate, and the slightest shift can have a domino effect resulting in bizarre consequences that seem totally unrelated to the original cause. Here we look at four of the more unusual effects of anthropogenic climate change on the planet. Continue reading “Four Unusual Horsemen – Weird Consequences of Climate Change”
