See how much the sea ice is increasing in Antartica! /s

As always with CBC articles it's important to read them from the bottom up.

"Big icebergs break off Antarctica naturally, meaning scientists are not linking the rift to man-made climate change. The ice, however, is a part of the Antarctic peninsula that has warmed fast in recent decades."

Now, did you notice the sneaky "However" in the quote above.

"The ice, however, is a part of the Antarctic peninsula that has warmed fast in recent decades."

So basically they're insinuating we aren't really talking about climate change, but we are. The are inferring the warming of the antarctic peninsula is a result of humans warming the planet with their horrible fossil fuel driven technologies.

CBC will always lay a little 'lie of omission on you, so let's look at what they're not telling you.

First of all let's check out a better map.



Notice how the area they're talking about - the antarctic peninsula juts out to seemingly almost touch the tip of South America.

Now let's go to NOAA and get a graphic of how the warm currents flow.

This animation shows the path of the global conveyer belt. The blue arrows indicate the path of deep, cold, dense water currents. The red arrows indicate the path of warmer, less dense surface waters. It is estimated that it can take 1,000 years for a "parcel" of water to complete the journey along the global conveyor belt.

Ice shells calf. They have ever since there have been ice shelves. They calf. Sometimes much of the broken off ice reseals. Sometimes it doesn't. Ocean born ice shelves like this one do not raise sea level when they break off any more than a melting ice cube will raise the water in your drink glass. They can create slack for land ice to push outward though, and that can raise sea level a smidge.

Without searching I can tell you and you may remember this is not the first ice calving in recent memory. And yet over the last several years the Antarctic ice of the continent when viewed as a whole has risen to record levels over the last several years (yes there was a recent brief melt during the super-El Nino, but the ice is regrowing.)

So yes Doc, overall the Antarctic sea ice has been increasing. And me, not a scientist or anything, but I don't see any reason to believe this particular ice shelf calf is going to diminish that in any appreciable way.

Since it's more ice at sea then you're right!

It's got too much so it's just shedding some of it... or so I heard.

I'm gonna need a bigger glass.
