Arctic sea ice appears to have reached on March 7 a record low wintertime maximum extent, according to scientists at NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) in Boulder, Colorado. And on the opposite side of the planet, on March 3 sea ice around Antarctica hit its lowest extent ever recorded by satellites at the end of summer in the Southern Hemisphere, a surprising turn of events after decades of moderate sea ice expansion.

On Feb. 13, the combined Arctic and Antarctic sea ice numbers were at their lowest point since satellites began to continuously measure sea ice in 1979. Total polar sea ice covered 6.26 million square miles (16.21 million square kilometers), which is 790,000 square miles (2 million square kilometers) less than the average global minimum extent for 1981-2010 – the equivalent of having lost a chunk of sea ice larger than Mexico.

Yeah and the GOP still refuses to recognize the physical reality of our warming globe and who’s to blame. 
Short term profits and power, is all they care about, so sad, any Right Wingers paying attention to weather reports?  Its getting uglier.

Sorry for the errors. The system won’tallow me to make corrections without deleting the past as spam. Below is the corrected comment.

 


Republicans won’t accept any scientific evidence. They have convinced themselves that global warming is a liberal plot to interfere with capitalism.

This looks like a good thread to park this in, excellent talk, good update.
Mainly Greenland, but some Antarctic info.

We just had three years of record heat. Now what I am understanding is that due to the higher heat the poles will get more snow because the warmer air will bring more moisture to the poles. And the pole to watch is the South Pole. Because 80% of the ice is at the South Pole. We could be losing ice at Greenland but still gain ice overall because of the South Pole. The link is about how there has been an increase in snow since 1965 at the South Pole. One of the reasons the Ice Cores goes back in time so far is that there is very little snowfall at the South Pole because of the dry air.

This is important because of snow caps melting in the northern hemisphere will cause sea level rise. And this could be offset by the buildup in the South Pole. It is hard to figure the ice numbers. Ice melts to water. Much easier to follow water levels.

Mike, damn you to Doug.  smirk
Here mikie demonstrates that he neither understands, nor appreciates the difference between snow and millennia old glacial ice.
Oops, I let the key hint slip, I was going to see if he could guess it.

Mike also offers another example of his WHAT IF SCIENCE being used to ignore FACT BASED, WELL KNOWN SCIENCE.

Antarctic Ice Sheet Mass -
The Antarctic Ice Sheet, covering nearly all of the Antarctic continent, is the largest single mass of ice on Earth. The ice sheet has multiple regions, each with their own unique ice dynamics. West Antarctica and the Antarctic Peninsula have generally lost mass over the last 15 years, and increasing mass balance in East Antarctica has not been enough to keep the ice sheet from losing mass as a whole (Martin-Español, 2016).

Since their launch in 2002, NASA’s Gravity Recovery and Climate Experiment (GRACE) satellites have been able to measure the local gravity changes near the Antarctic Ice Sheet, determining an approximate amount of ice lost each year in GT (gigatons; 1x1012 kilograms). In 2016, the Antarctic Ice Sheet had lost 1508 GT since measurements began in 2002 (this is 842 GT below the average mass of the 2002-2016 mean, Watkins et al. 2015).

But then honest curiosity and fidelity to the facts means noting to the politically driven misinformers such as our own MikeYohe.

He goes on to display some idiotic right wing logic: if you can somehow add up some numbers that seem to cancel out other numbers, that makes everything okay.  No appreciation for Earth’s complexities and interdependences.

They have no conception of our climate engine, with its balances and flows, how everything links together within a climate regime that goes back thousands and tens of thousand, heck you can trace it’s evolution back to the meteor that killed off the dinosaurs and beyond,
but what’s truly hideous is the GOP and those like our mikie are doing their best not to learn about it and interfere with other’s right to honestly learn.
