Thanks But I’d Prefer Not To Be Able To Take the Shortcut




I’ve excerpted a portion of an article from the European Space Agency’s website describing the emergence of the "Northwest Passage", which eluded explorers for millenia.  Now, thanks to unbridled carbon emissions and global warming, it is emerging.  In my view, the implications of this for mankind are staggering and are not good:

The area covered by sea ice in the Arctic has shrunk to its lowest level this week since satellite measurements began nearly 30 years ago, opening up the Northwest Passage – a long-sought short cut between Europe and Asia that has been historically impassable.

In the mosaic image [below], created from nearly 200 images acquired in early September 2007 by the Advanced Synthetic Aperture Radar (ASAR) instrument aboard ESA’s Envisat satellite, the dark gray colour represents the ice-free areas while green represents areas with sea ice.
 

Leif Toudal Pedersen from the Danish National Space Centre said: "We have seen the ice-covered area drop to just around 3 million sq km which is about 1 million sq km less than the previous minima of 2005 and 2006. There has been a reduction of the ice cover over the last 10 years of about 100 000 sq km per year on average, so a drop of 1 million sq km in just one year is extreme.

Again, this is not good.It may already be too late to reverse this course of melting ice, but the collective "We" need to do something about it, now.  Suggestions welcome.
