Neil deGrasse Tyson emphasizes the serious threats posed by climate change, particularly focusing on the impact of greenhouse gases and the severe consequences of melting polar ice caps.
He frequently highlights that the release of greenhouse gases can negatively alter the Earth's climate. A significant concern he often articulates involves the melting of the planet's vast ice sheets. Specifically, Tyson points out that if the enormous ice caps covering Greenland and Antarctica—the two largest ice sheets globally—were to disappear, the water levels of the ocean would rise dramatically.
To vividly illustrate the scale of this potential disaster, he explains that such a rise would be enough to bring the ocean's surface up to the Statue of Liberty's left elbow. This compelling imagery underscores his view that climate change is a tangible and urgent threat with profound and far-reaching environmental consequences for coastal regions worldwide.
