No. The south pole is not expanding. How did you come up with that one?

To be pedantic sea ice doesn't count, as it is largely seasonal, and as made from sea water makes no difference when it melts.

What does count are the ice shelves which are made of ice from the mainland flowing outwards.

Those are the ones that make large icebergs when they break off.

IMO if sea ice is expanding it has to be because the sea is colder further out which sort of poses a problem for the "oceans are getting warmer" theories.

The Antarctic sea ice area expanded significantly during 1979–2015. This is at odds with state-of-the-art climate models, which typically simulate a receding Antarctic sea ice cover in response to increasing greenhouse forcing.

Pacific islands growing too.

 

"New research says hundreds of islands in the Pacific are growing in land size, even as climate change-related sea level rises threaten the region."

Ice melts yearly and reforms. It doesn't matter. In 10 years we will still hear the same warnings. Reality isn't matching the models. The 2nd law of thermo has been broken. These guys are guessing.

100% of the warming of the Earth came from or comes from the sun. Increased CO2 only results in more of that heat being absorbed by the planet.

Humans and volcanoes produce heat too, about 2%.

The rich will burn with us.

 

I'm old, and have no known offspring.

 

So I'm past caring. 

 

Since were all going to die no matter what the ice does, I just wanna drop in my tracks or in my sleep. 

 

Next topic...

Actual the topic is about the ice sheets on Greenland and Antarctica. It's not about the ice in your refrigerator and it's not about sea ice either.

And according to the authors, it is due to sea ice drift velocity, which was lower than expected.

Once again, sea ice is not the ice sheets of Antarctica or Greenland. Sea ice is ice that is formed from sea water.

"Sea ice covers the ocean surrounding Antarctica, forming a key component of the coupled ocean-atmosphere-cryosphere system in southern high latitudes that helps regulate climate, ocean circulation, and marine ecosystems. The extent of Antarctic sea ice varies greatly from year to year, but 40 years of satellite records show a long-term trend. "

And the reason is that health coral reefs are adding enough sediment to outpace rising sea levels. So what's your point?

Sea ice in Thailand? No

 

"Sea ice is frozen seawater that floats on the ocean surface. It forms in both the Arctic and the Antarctic in each hemisphere's winter; it retreats in the summer, but does not completely disappear."

By your understanding of the second law of thermodynamics, not only greenhouse gases but greenhouses wouldn't be possible.

A new generation of satellites and ocean bases sensors has confirmed that more energy is entering the earth's atmosphere than is leaving it.

Joint NASA, NOAA Study Finds Earth's Energy Imbalance Has Doubled

 "NASA's Clouds and the Earth's Radiant Energy System (CERES) suite of satellite sensors measure how much energy enters and leaves Earth's system. In addition, data from a global array of ocean floats, called Argo, enable an accurate estimate of the rate at which the world’s oceans are heating up. Since approximately 90 percent of the excess energy from an energy imbalance ends up in the ocean, the overall trends of incoming and outgoing radiation should broadly agree with changes in ocean heat content.

https://www.nasa.gov/feature/langley/joint-nasa-noaa-study-finds-earths-energy-imbalance-has-doubled

 

That imbalance is due to the fact that greenhouse gases are slowing the exit of infrared radiation from the planet.

Just because some a local phenomenon hasn't yet been figured out, doesn't mean that the large madel isn't working astonishingly well.

Always so negative.

What has sea ice got to with the South Pole? And the South Pole is not the same thing as Antarctica. Not even nearly.  Antarctica is a continent. How does the expansion of ice floating on the sea mean that the South Pole, or, for that matter, Antarctica are growing?

IMO you are confusing heat and temperature.

If the oceans on earth warm by 2 degrees C, it's an insignificant change in temperature. On the Kelvin scale, about 0.7 %. It's one hell of a significant change in the amount of heat stored in the oceans, which in turn causes melting ice, and more violent storms.

Well, what denialists do is to take a figure of speech, like "earth is in trouble" and take it literally instead. If someone has Asperger's syndrome, this is understandable. Otherwise, not so much.

Don't know what a denialist is but if you have to insult people with names it means you lost already.

What I was getting at is that taking figures of speech literally is obviously a ploy. A way of avoiding the issue. They're just playing at being dumb. Like claiming that they don't know what a denialist is.

How exactly am I cherry picking? This is an article about the acceleration of the melting of the ice sheets in Antarctica and Greenland. What's the good new here?

The good news is southern sea ice is expanding. Pacific islands are expanding. No warming since 2016.  The 2nd law of thermo broken.

 

Yet you cherry pick bad news to suit an agenda.
