The global warming fear mongers are at it again.
Twice recently they’ve been caught in the act-- not only are they lying, they're so desperate that they're starting to look ridiculous.
“Three years of observations show that the Antarctic ice sheet is now losing 159 billion tonnes of ice each year,” reports the UK’s University of Leeds, “twice as much as when it was last surveyed. A team of scientists from the UK Centre for Polar Observation and Modelling, led by researchers at the University of Leeds, have produced the first complete assessment of Antarctic ice sheet elevation change.”
Like you, I'm suspicious of any group of scientists that live in a “kingdom” that can’t even practice general dentistry correctly.
Or, apparently, math.
The press release goes on to say that the ice melt could contribute to an increase in “global sea levels by 0.45 millimetres each year alone.”
That's really not that impressive a figure when you understand that means about a 2 inch rise over 100 years. But what's really impressive about the figure is that it's just not true.
From Climatesanity: Conversion factors for ice and water mass and volume
If one cubic kilometer of water (i.e., one gigatonne of water) is spread evenly over the entire 361 million square kilomters, the thickness of the new layer of water will be given by:
1 km³ / 361 x 106 km²= 2.78 x 10-6 meters= 2.78 microns.
Or, in terms of gigatonnes:
1 Gtx(1 km³/Gt)/ 361 x 106 km²= 2.78 x 10-6 meters= 2.78 microns / Gt
That is, one cubic kilometer of water (i.e., one gigatonne of water) will add less than 3 millionths of a meter to the oceans!
From the press release, we are seeing about 159 billion tons/year of ice converted to meltwater (unless it sublimates), so the effect on sea level would be 159/1000 or 0.159 x 3 millionths of a meter, or 0.477 millionths of meter of sea level rise per year from this.
I'll leave it to the highly trained scientist at the University of Leeds to convert the millionths of a meter into inches for you. But it's my strong recommendation you not allow them to do your taxes.
But hold on there partners, we’re not done yet.
