Penguins as Signs of the Planet's Future

Back when I was researching Antarctica for my research projects I often heard about the Antarctic being considered the early warning sign for global climate change. Today I found a recent article about Adelie penguins that talks about how they are being affected by climate change. It discusses the decreasing amount in the penguin populations that are in particular occurring on the Peninsula where most of the Antarctic warming is occurring. It also talks about the last Emperor colony on the Peninsula being in danger of disappearing. It is sad to see that these species of penguins could be heading towards the endangered list where 3 of the 17 world penguin species already are.
