Arctic Sea Ice Hits Smallest Extent In Satellite Era
Satellite data reveal how the new record low Arctic sea ice extent, from Sept. 16, 2012, compares to the average minimum extent over the past 30 years (in yellow). Sea ice extent maps are derived from data captured by the Scanning Multichannel Microwave Radiometer aboard NASA’s Nimbus-7 satellite and the Special Sensor Microwave Imager on multiple satellites from the Defense Meteorological Satellite Program.

NASA satellite data reveals how 2011’s minimum sea ice extent, reached on Sept. 9 as depicted here, declined to a level far smaller than the 30-year average (in yellow) and opened up Northwest Passage shipping lanes (in red).

Sunday morning I stopped by the local Ikea store to pick up a table for my laptop computer. What was supposed to be a short 20-30 minute trip ended up taking me two hours. If you’ve ever been to an Ikea store, one thing you quickly recognize is they are masters at merchandising. Arrows on the floor direct you through the maze of each department and almost every product is displayed to “help you” see just how affordable and easy it is to furnish any living space with put-it-together-yourself furniture. I know I’m being marketed to and I’m ok with that. I still enjoy browsing and window shopping at Ikea. Plus, if I’m hungry, they have a pretty good deal on breakfast and Swedish meatballs.
As I walked through the store this particular day, I took a good look at their lighting display. What I appreciated about the display is how effective it was at showing the benefits of converting standard incandescent light bulbs to energy efficient CFL bulbs.
This is just another story I’ve come across recently paints a stark picture of the impact humans are having on the earth:
From “The Register” – Published Friday 15th February 2008 13:00 GMT
40 per cent ‘heavily affected’ by human activities
“A new global map compiled by analyzing 17 different factors including
fishing, global warming and pollution has revealed that 40 per cent of
the world’s oceans are heavily affected by human activities, while just
a small percentage of seawater has completely escaped the effects of
man’s heavy hand.”
Not very cheerful, is it? For the Register’s full story, click here
