Tides wait for no man

Everybody is going on about how Venice is climate change.

Yet, even the guard doesn't blame UK flooding on climate change.

That's because of the cold.

There was also a risk of seeing a very cold start on Tuesday, according to Yeomans, with potential temperatures of -5C (23F).

You can't have anything to do with climate change when it is the coldest and wettest autumn ever.

The Met Office said its Sheffield weather station had recorded its wettest ever autumn.

If it is climate change then it is sea level rise due to global carbon warming.

So, I looked at the Bermuda tide gauge.

Bermuda is sinking.  That's the problem with 'sea level change', every piece of dirt is either rising or sinking.  If we take out the trend.

then we get a lovely flat plot which shows the effect of El Ninos.  I magnified the last bit, since 2013.

It reflects exactly the global temperatures as determined by satellite.  And there is a bit of a lag.  Sea level changes reflect the overall temperature of the oceans.  Warm water expands.  You can see our last El Nino (after 2016-17) and the plunge now.  So, is Venice carbon warming?

To remind people here is the global temp chart.

Had Venice flooded at the peak, then maybe.  But it was a combination of huge rains and high tides.

Cold, miserable weather for Canada


Now, weather chan is the warmiest thing there is.  They had to throw in a climate comment. 

We have a pattern of 'short plumes' going like soldiers over the Pacific.

These will slam into Canada, and drive away the Gulf air.  Between these plumes we should get Arctic air.

These are being driven by a reverse current in the Pacific, which isn't that warm, and is not part of any El Nino.  It's just one of these weird things that nobody measures.

Ocean currents -- Nov 15, 2019

Today's big story is the massive Arctic current.  For the first time, that I have seen, there is net flow into the Bering Straight.

This is the current coming around Greenland.  It stops the Gulf Stream and plunges all the way to the equator.

I had thought it was just rejected saline from the Arctic ice build-up, but there is net flow into the Arctic.  Last week it seemed to be much more.

This flow is causing the ice-free zone around Alaska, which the warmies are holding up as a warm thing.

They are also making hay on the lag in this chart.  It was building up very fast, but now has resumed the normal rate.  You can see the big chunk taken out around Alaska.  We've had a lot of tropical plumes hitting that zone, and there are strong currents.  It should fill in soon, as all the warming influences have stopped.

ps.  Yeah, vw is going from the diesel disaster straight to the lithium disaster.  I love it.
