Penguin numbers suffering with krill decline due to Global Warming

A new study of declining penguin populations shows a strong correlation between penguin numbers and krill availability. Krill availability is affected by reduced sea ice conditions due to global warming and climate change.

"For penguins and other species, krill is the linchpin in the food web. Regardless of their environmental preferences, we see a connection between climate change and penguin populations through the loss of habitat for their main food source," said Dr. Wayne Trivelpiece, lead author and seabird researcher of the National Oceanic and Atmospheric Administration's Antarctic Ecosystem Research Division. "As warming continues, the loss of krill will have a profound effect throughout the Antarctic ecosystem."

Arctic Sea Ice extent winter maximum continues sea ice decline

Arctic sea ice extent has just passed it's maximum - estimated to be March 7 this year. Only this year it has tied with 2006-2007 as the lowest on record according to satellite records that began in 1979.
