Ocean extinctions increase

A June 21 news story that appeared on the website at reuters.com discussed a study that may demonstrate that ocean life is at risk of “the worst spate of extinctions in millions of years due to threats such as climate change and over-fishing.”

The study, conducted by the International Programme on the State of the Ocean, said there was little time to address such issues as the collapse of coral reefs and the spread of low-oxygen “dead zones.”

Greenpeace executive arrested on arctic rig

The international executive director of Greenpeace, Kumi Naidoo, was arrested and flown to Greenland after breaching an exclusion zone and scaling a controversial Arctic oil rig about 75 miles out to sea.

At 6:45 a.m. on Friday, June 17, an inflatable speedboat carrying Naidoo was launched from the Greenpeace ship Esperanza. The rig’s operators, Cairn Energy, used water cannons to try to prevent him from climbing a 100-foot ladder up the outside of one of the rig’s giant legs, but Naidoo made it to the platform, where he demanded that Cairn immediately halt drilling operations and leave the Arctic.

He also sought a meeting with the master of the rig so he could present the names of 50,000 people from across the world who have emailed Cairn to demand they publish the rig’s secret oil spill response plan. The document has been at the center of a month-long campaign of civil disobedience in the Arctic.

The area where Cairn intends to drill is known as Iceberg Alley. According to a Greenpeace press release, the company intends to tow icebergs out of the rig’s path or use water cannons to divert them to avoid a collision as the rig drills for oil.

According to the website wordorigins.org, “Scuttlebutt is an early 19th century nautical term for an open cask of water kept on deck for use by the crew. The term comes from scuttle — to cut a hole in — and butt — a large cask. Sailors would gather about the cask and trade stories and gossip, much like modern office workers do at the water cooler or coffee pot. By the turn of the 20th century, American sailors began using the term scuttlebutt to refer to these sea stories and gossip. Eventually the term became associated with any gossip or rumor.”
