Gulf Stream becomes confused

The main thing that keeps us Northern people warm are the giant oceanic plumes like the Gulf Stream.

We are lucky by plate tectonics that there is a perfect ramp with South America deflecting the warm water up to Britain.  We, in Canada, mainly benefit from the Gulf of Mexico and Pacific plumes.  For some reason, the Gulf Stream plume is confused and may not be working at full capacity.  There is a bit of a backwash.  In my fertile imagination, I think of the main equatorial current shifting a bit more south and missing the ramp completely.  That would be a true mini ice age for the North.

My working hypothesis is that we enter our Snowball Earth phase when all the continents are well separated.  At that point, the oceanic heat pumps work to dump heat towards the poles.  My problem is demonstrated here, in that an efficient heat pump like the Gulf Stream would make the Arctic warmer.  I can only conclude that all the heat is deflected to the south.

PS.  The Gulf of Mexico is heated by this current, as well.  Should it turn off, we would get continental glaciation up here in Canada.  It wouldn't be successful because the land is depressed by the last glaciation.  But in 5000 years, if it turns off, we get another ice age.  If the equatorial current dips below the South American prow, we would just get another mini-ice age.

Cottage Report - Friggin Freezing

This is the weekend before final closing.  We have lake only access, so I had to push the boat against a NE gale at near freezing temps.  The water is drawn down 4 feet, so I had to tilt the motor way up to leave the dock.  Right now we are surviving in the uninsulated shack with a nice fire.  This place is a summer thing, and tomorrow it'll take a day to split firewood for a day.

Still, the colours are just starting, and next weekend they should be at a peak.  It's great weather to put everything to bed and not miss it, since I would never want to be here any later.  Although it is nice to think of a sunny winter day with white fluffy snow, there is a lot of really nasty weather to get there.  :)

El Nino Beaten Back Again

The El Nino backwash made one lunge earlier, which flooded Los Angeles.  Now it has been beaten back to sit under Hawaii.  This mass of hot water affects our NA weather by sucking in hurricanes, and mucking with October chills.  As well, it is spinning typhoons to China.

We must wait for another lunge to Central America to have any effect on the Callie drought.  I think until then we should only call it a Baby El.  :)  Many other good prospects have failed at this point.
