Antarctic Ice Bridge Shatters

Here’s an inconvenient truth: A bridge to the Wilkins ice shelf, an Antarctic peninsula the size of Jamaica, has shattered. Scientists think the shelf is now on the brink of breaking away, a development that could be a direct effect of global warming in this part of Antarctica. Temperatures in Antarctica have risen up to 5.4 degrees Fahrenheit in the past 50 years, and shattering ice there has a big effect on sea levels worldwide.
