Tally of Antarctic Sealife Sheds Light on Changing Climate
 The British Antarctic Survey (BAS) presents the results of its ongoing census of marine life in the Antarctic at a meeting of the American Association for the Advancement of Science. The BAS census has been documenting the diversity of marine life in Antarctic waters and the way it is changing in response to climate change.Marine Biologist Huw Griffiths from British Antarctic Survey (BAS) is involved in this major international investigation into the distribution and abundance of Antarctica’s vast marine biodiversity - the Census of Antarctic Marine Life (CAML).More than 6,000 different species living on the sea-floor have been identified so far and more than half of these are unique to the icy continent. A combination of long-term monitoring studies, newly gathered information on the marine life distribution and global ocean warming models, enable the scientists to identify Antarctica’s marine “biodiversity hotspots”.Researcher Griffiths describes how krill populations (the shrimp-like invertebrates eaten by penguins, whales and seals) are reducing as a result of a decrease in sea-ice cover. A much smaller crustacean (copepods) is dominating the area once occupied by them. This shifts the balance of the food web to favour predators, like jellyfish, that are not eaten by penguins and other Southern Ocean higher predators. Sea-ice reduction is also affecting penguins that breed on the ice.Images of marine life counted in the census are truly amazing.

A Little Green Math Challenge For You–(because my calculator watch just broke)
OK–as a new signer upper for Ameren’s Pure Power Plan I am curious about 1 thing: How can I present this to my wife as an economical decision? Two things are apparent from that question: 1. I signed up without telling my wife–not usually my style, I guess I was just hoping she wouldn’t notice. 2. She won’t be down with supporting modern energy. Not true–she’s down. It’s just that she is more fiscally conservative than I. So here is my math problem for you: Ameren’s Pure Power Plan asks the customer to pay 1.5 cents per kWh. Let’s say. |

Rethinking renewable energy strategy
Researchers suggest that policy makers examine greenhouse gas emissions implications for energy infrastructure as fossil fuel sources must be rapidly replaced by windmills, solar panels and other sources of renewable energy. |
