"I don't see any future for whale species except extinction." A
report (pdf) released Thursday by
Ocean Alliance noted high levels of cadmium, aluminum, chromium, lead, silver, mercury and titanium in tissue samples taken by dart gun from nearly 1,000 whales over five years. Concentrations of chromium found in some whales was several times higher than the level required to kill healthy cells in a Petri dish. Mercury in some whales was 16 times higher than a typical shark or swordfish, both known for their high mercury levels.
Beyond whales, "You could make a fairly tight argument to say that it is the single greatest health threat that has ever faced the human species."

The Polar Discovery team has documented science in action from pole to pole during the historic 2007-2009 International Polar Year, and
covered five scientific expeditions. The science projects explored a range of topics from climate change and glaciers, to Earth’s geology, biology, ocean chemistry, circulation, and technology at the icy ends of the earth. Through
photo essays and
other multimedia, they explain how scientists collected data and what they discovered about the rapidly changing polar regions. From the awesome folks at
WHOI.

Most people have heard about how rising CO2 levels are resulting in a
changing global climate. Fewer have heard about the other consequence of rising CO2 levels- when the CO2 is absorbed into the oceans, it disassociates into carbonic acid. This alters the pH of our world's oceans, and it's called "
Ocean Acidification". This changing ocean chemistry has many important and devastating consequences.

Time to pull out the giant salt shaker - Evidence supporting Abrupt Climate Change theory builds (from a new study published in
Nature Magazine, April 22 2004) : "Rate of Ocean Circulation Directly Linked to Abrupt Climate Change - A new study strengthens evidence that the oceans and climate are linked in an intricate dance, and that rapid climate change may be related to how vigorously ocean currents transport heat from low to high latitudes....(From the ever superb
