“The importance of carbon dioxide in regulating the Earth’s temperature was confirmed by scientists working in eastern Antarctica. Drilling down into a glacier, they extracted a mile-long cylinder of ice from the hole. The glacier had formed as layer upon layer of snow accumulated year after year. Thus drilling into the ice was tantamount to drilling back through time.” (Tầm quan trọng của carbon dioxide trong việc điều chỉnh nhiệt độ Trái đất được xác nhận bởi các nhà khoa học làm việc ở phía đông Nam Cực. Khoan xuống một dòng sông băng, họ rút ra một khối băng dài hàng dặm từ lỗ. Sông băng đã hình thành như một lớp trên lớp tuyết tích tụ qua từng năm. Do đó, việc khoan vào sông băng đã tương đương với việc khoan ngược thời gian.)
