I love creationists. Who else can unblinkingly believe two penguins walked from Antarctica to the Middle East to get on Noah's' Ark?
Originally, the climate was created perfect, but sin changed everything (Genesis 3), and we no longer have a perfect climate. During the global Flood of Noah’s day about 4,350 years ago the climate was radically changed when the surface of the Earth was reshaped by the Flood. The Flood was followed by an Ice Age, which further changed our climate, and climates have gone up and down since.
