How does global warming affect the animals that live in Antarctica?
The main way climate change can affect penguins, for example is though snow at their breeding colonies. When you have heavy snow that lasts longer the birds find it harder to breed as they prefer snow free areas to built their nests. What weather changes have been noticed over the last 5 years? Although everyone is talking about “global warming” and “climate change”, this is not possible to measure over a short time such as 5 years. If the climate was steady and unchanging, the weather (what happens every day) would still change from day to day, and from year to year. Sometimes you would get a very cold winter, or a dry summer, but this is what we call “natural variability”. Seeing a constant change in the same direction is not possible, so we must watch the weather for 10s or 100s of years….. So, I have noticed many “changes in weather” over the last 5 years, it was very wet this winter, for instance, but I would not say this is “global warming”. However, I have data from Halley, An
