Last July, Greenland broke the Northern Hemisphere record for July cold, and they are breaking cold records again.
Arctic sea ice volume continues as the highest in 13 years, and is melting the slowest on record. With cold weather forecast past July 4th, the odds of a big melt this year are close to zero.
With their Arctic scam falling apart, climate alarmists have returned to their Antarctic scam – claiming that Antarctica is melting in the middle of the Antarctic winter.
Climate alarmism is the most pathetic clown show on earth.
Sixty years after the New York Times predicted Arctic shipping, there are still no ships in the Arctic. Arctic sea ice volume is the highest in thirteen years, the ice is melting at the slowest rate on record, and continued cold is forecast for the rest of the month.
Ten years ago, Arctic sea ice was very thin and our top climate scientists announced the ice was screaming and was about to disappear.
Ice near the pole has doubled in thickness since then, ice volume is the highest in thirteen years, and is melting the slowest on record.
Climate scientists have absolutely no clue what they are talking about, but if you reject their junk science, you are an evil denier.
In a letter to the Washington Post, Sherwood Boehlert, a retired Republican congressman who once headed the house science committee, wrote: “I call on my fellow Republicans to open their minds to rethinking what has largely become our party’s line: denying that climate change and global warming are occurring and that they are largely due to human activities.”
As I have been saying for most of the last decade (including two days ago) climate scientists are incompetent hacks who have no clue how to interpret gravity data.
NASA glaciologist Jay Zwally first challenged the “consensus” on Antarctica in 2015 when he published a paper showing ice sheet growth in eastern Antarctica outweighed the losses in the western ice sheet.
Zwally will again challenge the prevailing narrative of how global warming is affecting the South Pole. Zwally said his new study will show, once again, the eastern Antarctic ice sheet is gaining enough ice to offset losses in the west.
So, why is there such a big difference between Zwally’s research and what 80 scientists recently published in the journal Nature?
There are several reasons for the disagreement, but the biggest is how researchers make what’s called a glacial isostatic adjustment (GIA), which takes into account the movement of the Earth under ice sheets.
Scientists use models to measure the movement of land mass in response to changes the ice sheet sitting on top. For example, Zwally said eastern Antarctica’s land mass has been going down in response to ice sheet mass gains.
That land movement effects ice sheet data, especially in Antarctica where small errors in GIA can yield big changes ice sheet mass balance — whether ice is growing or shrinking. There are also differences in how researchers model firn compaction and snowfall accumulation.
“It needs to be known accurately,” Zwally said. “It’s an error of being able to model. These are models that estimate the motions of the Earth under the ice.”
Zwally’s 2015 study said an isostatic adjustment of 1.6 millimeters was needed to bring satellite “gravimetry and altimetry” measurements into agreement with one another.
Shepherd’s paper cites Zwally’s 2015 study several times, but only estimates eastern Antarctic mass gains to be 5 gigatons a year — yet this estimate comes with a margin of error of 46 gigatons.
Zwally, on the other hand, claims ice sheet growth is anywhere from 50 gigatons to 200 gigatons a year.
I find it incredible that anyone would be stupid enough to report precision ten times greater than their error, but nothing from these incompetent hacks known as climate scientists surprises me any more. Nobody knows what is going on under the ice sheet, and claiming they can detect gravity changes in a two mile thick low density ice sheet sitting on top of five thousand miles of dynamic high density rock – is beyond the pale.
And the same problem also applies to fake Greenland graphs like the one below. People who make these graphs have absolutely no clue what they are doing, other than defrauding the public.
We are expecting another three inches of rain this week.
Arctic sea ice volume is highest in 13 years, and melting at the slowest rate on record. During most years, after July 25th volume melt rates drop off sharply, so Arctic alarmists have about 40 days to wipe out 20 trillion tons of ice.
Thick ice is blocking both the Northern Sea Route and Northwest Passage
The next two weeks typically have the highest volume melt rates of the year, and cold weather is forecast over the Arctic.
Rather than admitting their prophets are incompetent, clueless and wrong, Arctic alarmists will continue to whine, complain and nitpick. But their scam is just about out of steam – and the clock is ticking.
Graphs like the one above purporting to ice loss in Greenland and Antarctica are worthless, for several reasons.
- The are generated by people with a global warming agenda who don’t understand the mathematics and science underlying their calculations.
- Gravity data shouldn’t change as the ice grows or melts.
The Greenland ice sheet is two miles thick and is is very heavy. It’s weight depresses the crust and causes the mantle to be displaced to the sides. The mass of displaced mantle is approximately equal to the mass of the ice sheet. If the ice sheet was growing, it would cause an equal mass of mantle to be displaced to the sides. If the ice sheet was shrinking, it would cause an equal mass of the mantle to flow back under the ice sheet. Whether the ice sheet is expanding or shrinking, the total mass in a vertical column should be relatively constant.
Climate scientists aren’t very bright, and don’t understand the basics of geology and geophysics.
estimates failed to account for glacial isostatic adjustment
Unless you understand what is going on underneath the ice sheet, you can’t use gravity data – and no one really knows what is going on underneath the ice sheet. Rock is three times as dense as ice, and small changes in geology show up as imaginary large changes in ice.
Greenland’s largest glaciers have been expanding over the past six years.
The surface mass balance is rapidly growing. But let’s ignore all that and focus on junk science gravity interpretations by climate science hacks.
For the second year in a row, Greenland’s surface has gained well above average amounts of ice.
Climate experts have tried to blame this on warm sea surface temperatures, but the water around Greenland is record cold.
As we approach the summer solstice, temperatures in Greenland’s interior are -13C.
Desperate to keep their scam alive, climate experts have ramped up the BS to the highest level in at least four centuries.
