Earth is currently experiencing a period of global warming enhanced by greenhouse gases. Based on your knowledge of the effects of major climate change throughout geologic time, such as the global warming leading up to the end of the Permian period, which of the following is a reasonable hypothesis for the effect this global warming will have on Earth's ecology.

• Earth's ecology will only benefit from the warmer climate.

• Many species will be unable to adapt and will go extinct.

• The effects of global warming will not have any long-term effects on the human species.

• Global warming will likely have no effect on Earth's ecology.
