Why, yes....yes we are. But we'll be right back. Laundry day.

this winter's polynya had an area of open water close to 80,000km2. This marks the second year in a row in which the polynya has formed, although it was not as large last year.


This also from the article. Though it is said it is the largest in that sea, this appears to be a common occurrence and is smaller than the hole from last year.

Though something also tells me you don't feel this way when it comes to The National Weather service issuing you flood and wind advisory warnings for upcoming hurricanes landings in your area? Something tells me you don't label that fake news.
Ironically, these alerts are often wrong, and we're talking about alerts for events that are happening within 24-48 hours, yet we are expected to trust this same methodology when talking decades or centuries from now.

Why was the a hole in the ice in the 1970s?

I live at an elevation of 1089 ft.

No floods or hurricanes bother me at all

Temperature collection and the infrastructure underlying it is one of the most stable and well established constructs in human civilization. Even during WWII when we were at war, adversaries and the underlying weather infrastructure remained cooperative and operational. I have no reason to doubt that the temperature in Denver right now is 68 with little deviation.



Oh my goodness. Do you really think this is a matter of lack of confidence in thermometers? Get real man. Even the most ardent climate change alarmists would cringe at this ridiculous simplification.

While forecasting is not a 100%, temperature gathering is pretty straightforward. Measuring basic thermal expansion has been known about and going on since at least ancient Alexandria.

A "hole" in sea ice comprising about 15/1000ths of a percent of the Earth's surface in 24hr/d subfreezing temperature and near darkness is "leading to significant impacts on climate"?

That is quite a trick!

You failed to spell out the whole specific "why" and "what" aspect is of issue in your response.

The poster claimed we can't trust the average temperatures calculated and gathered from the incredibly decentralized, scrutinized, and well established global temperature gathering infrastructure. Which is just nonsense. Further compounded by the simple fact that we already know what the underlying science tells us. Which is enshrined in the basic foundational principles of atmospheric science. The most relevant aspects known since the 1860's.

I remember being told in elementary school in the 1970's that a new ice age was coming.

University of Toronto atmospheric physicist Kent Moore has told Motherboard: “This is hundreds of kilometers from the ice edge. If we didn’t have a satellite, we wouldn’t know it was there.”


So we don't know if this is reoccurring or how long its been there.

A mysterious, massive hole, as large as Lake Superior or the State of Maine, has recently been spotted in the winter sea ice cover around Antarctica.
But is it that mysterious because it's maybe been there for a while:
quote:

This opening, known as a polynya, is the largest observed in the Weddell Sea since the 1970s.
But has it always been there - because it hasn't been observed (this big?) since the 1970s?
quote:

Ocean convection occurs within the polynya bringing warmer water to the surface that melts the sea ice and prevents new ice from forming.
But if new ice can't form, how does its size change (from smaller to bigger since the 1970s?)?
quote:

Due to the harshness of the Antarctic winter and the difficulties of operating within its pack ice, there exist few direct observations of these polynyas and their impacts on the atmospheric and oceanic circulation.
Wait - didn't they just say something about changes in 'observations' from the 1970s?
quote:

With these new ocean measurements, along with space-based observations and climate models, comes the possibility that these polynyas' secrets and their impacts on the climate may finally be revealed.
Perhaps the technology machines can make the unpossible connections implied in this convloluted lead-up come true!

Did you decide to stop learning in the 70's and call it a day?

I think the implication was pretty clear: there have been hyperbolic assertions going back at least to Rachel Carson and the only things they have had in common are their vapidity and an unerring ability to completely miss the target...

Keep beating up on that strawman.

He's talking about how temperatures are analyzed and presented to the public. Referring to it as a "shell game", which I can only conclude means that there is an attempt to show data that supports a particular hypothesis while obfuscating data that doesn't. At no point did he say raw measurements are unreliable or impossible. This isn't a debate about the accuracy of thermometers, though I'm sure that's much easier for you to address.
