While it is good news that at least some species may evolve as oceans acidify, there is still much uncertainty. How will the complex environment of the real ocean with its multitude of interacting species affect this process? http://evolution.berkeley.edu/evolibrary/news/121001_acidicoceans
When the International Panel on Climate Change says “very likely” they mean greater than 90 percent. But researchers have found that to a non-scientist, “very likely” sounds more like a 62 percent chance. That’s a big difference.
A variety of factors can increase the vulnerability of specific demographic groups to health effects due to climate change. For example, older adults are more vulnerable to heat stress because their bodies are less able to regulate their temperature.
