[Our expedition leader on board the Arctic Sunrise looks back on our weeks at Petermann Glacier] After spending more than five weeks waiting for Petermann Glacier in northwest Greenland to calve a 100km2 ice island into the sea, at around midnight Wednesday night the Arctic Sunrise began its transit down the west coast of Greenland. Our primary goal at Petermann Glacier was to document the calving of the ice island with remote time-lapse cameras perched on 1000m cliffs overlooking the glacier. Even though the ice island has not yet calved, our time-lapse cameras remain in place, ready to document the glacier's disintegration, should it happen this summer.
People have been asking if I am disappointed that Petermann Glacier did not calve the large ice island while we were there. My honest answer is no. From the early stages when we first started planning this expedition, I was keenly aware that ice conditions in Nares Strait meant the ship had only a 50/50 chance of reaching Petermann Glacier in the first place. In reality, our passage north was virtually clear of sea ice – we sailed right to the top of the strait, reaching the an ice bridge holding back the Arctic Ocean's thick, multi-year sea ice on June 29th, just 445 nautical miles from the North Pole. The fact that we actually reached Petermann Glacier at all, and then had more than five weeks to conduct research into the dynamics that influence it and nearby Humboldt Glacier's sensitivity to global warming, was truly an unexpected bonus. Together, Petermann and Humboldt glaciers drain a full ten percent of the ice that flows from the immense Greenland Ice Sheet into the sea, with serious implications for sea level rise the world over. The independent science team on board gathered a lot of important data in a part of the world that is remote and challenging to reach. With the support of the Arctic Sunrise and her crew, the scientists were able to conduct glacier and oceanographic studies that will help fill the gaps in their and the greater scientific community's understanding of how Greenland's glaciers and ice sheet react to global warming. In the last seven years, the Greenland Ice Sheet's contribution to sea level rise more than doubled, due to a surprisingly rapid and unpredicted loss of ice. Against this backdrop, there is still so much that scientists do not understand about how Greenland's glaciers and ice sheet react to global warming. It's a stunning example of how the impacts of global warming on the ground are outpacing scientific models, which is the case throughout the Arctic and in much of the world. Ironically, while the Arctic Sunrise was conducting research on glaciers in northwest Greenland, the G8 met in Italy and failed to make any meaningful progress toward a climate deal. There is a huge gap between what countries are willing to do and what climate science is saying the planet needs. Not one head of state is prepared to do what's necessary to prevent climate catastrophe. At the end of the day, if the Copenhagen Treaty forged in December does not include science-based targets of at least 40 percent reductions in greenhouse gas emissions by 2020, then it will fall far short of what is needed. Even emissions reductions of 20 or 30 percent by 2020 won't cut it; it's just not possible to save the climate a little bit at a time. Obama, Merkel, Sarkozy and other heads of state can't shut their eyes and hope this issue will somehow go away. It won't. In coming years and decades we will all wonder what the heck they were thinking when they failed to address the problem with meaningful action. I know it's naïve, but I wish these heads of state could spend just one day with us on board this ship, talking with the independent science team on board about how climate change is affecting Greenland's glaciers and ice sheet, and in turn, what it means for the US and the rest of the planet. They would leave the ship understanding that anything less than science-based targets in US and global climate policy condemns the world to the worst impacts of climate change, which, by the way, will ravage their national and the global economy in incalculable ways. The economic recession that started with sub-prime mortgages and bank failures in the US will seem like child's play compared with what continued and unabated global warming will cause. The Arctic Sunrise is now heading south toward the next stages of this expedition. Independent science teams will be joining us to conduct research on Greenland's east coast glaciers as well as sea ice. We will continue our work here in Greenland, using every tactic we can to amplify the voices of scientists who are on the cutting edge of global warming research. Our hope is that both their work and voices will form part of the impetus for heads of state across the planet to take real action on global warming in the four months that remain before the Copenhagen climate talks in December. - Melanie

Hi Melanie...,
...and im my humble opinion, I feel it is you that is on the 'cutting edge' of holding Love in your hands for this earth, and the people and creatures in it. Because of people just like you, Greenpeace is the finest organization this world has ever known. Finer words, and a greater Love, I have never known. Thank you so much Melanie.
And congratulations to all of you on board and in administrative places for this significant and enlightening contribution to our planet, ...bourne of Love and to bringing about our ultimate understanding and awakening to these very real threats, we so blindly, ...and because of the absence of Love, ...we do unto ourselves. My grateful appreciation to you all so far away from home who have given so much, to give so much to us all. In the future, history will remember it was your Love that changed the world, and you will be remembered as the Warriors of the Rainbow, ...GC
