CLIMATE CHANGES
I wish when they do these stories they would specify the "record" they are refering to. Yellowknife is about sixty years old so for this area the record is 60 years long. There are some trading posts that go back a couple hundred years but I'm not sure what sort of records they kept.
There are ways we geologically and biologically that we can get a feel for the climate in general terms over longer periods of time, but they are in general terms.
So if someone says its the warmest or coldest year on record and the record is only fifty years long, its interesting but every few years you are going to get a record warm or cold year.
Since the last ice age melted around 16,000 years ago (the ice left the north around 10,000 years ago) no doubt we have had record warm and cold years which would make our recorder records seem fairly tame. Apparently during the period when the Norse settled in Greenland it was a warm phase because they were growing crops etc not able to do now, however there was a mini ice age later as shown it paintings of people skating on lakes in england which dont freeze now.
In various places some use climate shifts to explain the rise and fall of certain civilizations. The anastazi (sp) in the Us lived in fair size towns and grew corn in the midwest but suddenly it seems a climate change made the area un farmable.
Globally most of the planet for most of its time was a rather tropical temperate zone (hence tropical forests at high latitudes) then a couple million years ago the ice ages started. Right now they recon we are in an interglacial period. So what caused the ice ages to start. That is one of the great geological debates. One theory has it when through continental drift antarctic seperatred from south america the ice ages started. Its an interesting theory.
What causes individual glacial periods to start and stop is still not known.
So when they talk of record warm or cold years I really wish they would specify just what record they are referring to, how long is it and how accurate is it.
Personally a mild winter is great. Fuel and electrical bills are down, its alot more pleasnt at 20 below then 40 below C. And if we have have a real thaw I have some claims with great sand beaches on them which could be prime beach front property. On the other hand if a glacial period starts again its going to make all the land claims etc seem pretty silly because everyone in the top two thirds of North America will be heading south.

Great info Terry, i like this part best :

"Yellowknife Dene elder Joe Martin,..(said)

"It's been like spring and I asked (my angel) what was going on," Martin said.

"He told me 10 years from now things are going to be very different. The changes are starting right now -- this year."

He said the next decade will be a time for nature to reassert herself.

"All kinds of animals are going to rise up and when the winds come, they'll be over 300 km/h. Everybody is going to leave our town," Martin said.

"Freezing ice is going to fall, even in summer. It's going to hit windows, smashing them... Darkness is coming."
