The effects of global warming can already be seen in the animal kingdom. Researcher Bill Fraser has been tracking the rapid decline of Adelie penguins that reside on Antarctica. In a 30-year time span, breeding pairs have been reduced from 32,000 to only 10,000. Additionally, some butterflies, foxes, and alpine plants have begun migrating further north into cooler climates. The spruce bark beetle is now thriving in Alaska, thanks to rising temperatures. The bark beetle has already chewed up over 4 million acres of spruce trees to date 2. There are many more examples of animal and plant species adapting to the changing state of the environment. Polar bears today are much thinner and less healthy than 20 years ago. Coral reefs globally are anticipated to increase by up to a third in size. Marmots are ending their hibernation three weeks earlier. Songbirds now consume leaves saturated with carbon dioxide rather than insects. Some plant species are beginning to thrive in environments that are warmer than before 3. The examples are too numerous to mention in this research. While we focus on the human effects of global warming, we cannot disregard the impact it has on local and global animal species.
