Carbon dioxide levels are substantially higher now than at any time in the last 800,000 years, the latest study of ice drilled out of Antarctica confirms.
The in-depth analysis of air bubbles trapped in a 3.2km-long core of frozen snow shows current greenhouse gas concentrations are unprecedented. The East Antarctic core is the longest, deepest ice column yet extracted.
Project scientists say its contents indicate humans could be bringing about dangerous climate changes. ‘My point would be that there’s nothing in the ice core that gives us any cause for comfort,’ said Dr Eric Wolff from the British Antarctic Survey (BAS).
