Top news: Greenpeace leader Kumi Naidoo tells the WSJ about protecting people and the planet; melting sea ice is causing Arctic sea routes to open faster; Dolphins use a “conching” technique to catch fish.

#Kumi: A profile of our Greenpeace International Executive Director Kumi Naidoo in the Wall Street Journal includes praise for Naidoo from Anthony Van Jones, former environmental-jobs advisor to the Obama administration who says, “someone like Kumi, who has such impeccable human-rights credentials, says that protecting the people and the planet are twin duties. It showed a lot of foresight on Greenpeace's part to hire someone with that background." Thank you Mr Van Jones.

# Arctic: Richard Black in the BBC reports that Canada’s Northwest Passage and Russia’s Northern Sea Route are opening at the same time, according to data recorded by the European Space Agency’s Envistat. This was also confirmed by Greenpeace’s Arctic Sunrise expedition, while sailing through the Artcic archipelago, studying sea ice extent.  Halfway between Norway and the North pole, in  Longyearbyen, the ice edge that was supposed to be there, wasn’t. According to Leif Toudal Pedersen, senior scientist at the Danish Meteorological Institute, "the last five summers are the five minimum ice extent summers on record.” Some computer models show that the Arctic could be free of summer ice, within the next decade.

#Dolphins: Bottlenose dolphins in Australia’s Shark Bay are skillfully using conch shells to trap their prey. Though their exact methodology is not yet fully understood, it is believed that fish may swim into the shells, inadvertently trapping themselves. The shells may also be placed as traps on the seabed. This “conching” technique was most likely invented by single dolphin mothers, trying to feed their young and is not used as often by males. Another indication that the female sex is more resourceful?
