So if CO2 isn't a well mixed gas
Then why do all the worlds CO2 measuring stations show that it is increasing?

Also remember that due to air being highly mobile due to winds, a CO2 station can effectively monitor CO2 levels over a huge area.

Could it be that most of the CO2 measuring station are in the Northern hemisphere.

Well mixed means thoroughly blended through out the whole atmosphere.

If it was a well mixed gas it would show the same reading all over the world, the same increase all over the world, it wouldn't fade in parts while elsewhere it increases and elsewhere nearly absent.

Satellite data, tells us that "IT'S NOT A WELL MIXED GAS".

Like I said where is your evidence that it is..........???

Sea Ice Extent Sinks to Record Lows at Both Poles
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.


The March 7, 2017, Arctic sea ice maximum extent was a record low, due to warmer-than-average temperatures, winds unfavorable to ice expansion, and a series of storms. Antarctic sea ice also broke a record with its annual minimum extent on March 3.

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.

Arctic and global sea ice totals have moved consistently downward over 38 years. Antarctic trends are more muddled, but they do not offset the great losses in the Arctic.

The ice floating on top of the Arctic Ocean and surrounding seas shrinks in a seasonal cycle from mid-March until mid-September. As the Arctic temperatures drop in the autumn and winter, the ice cover grows again until it reaches its yearly maximum extent, typically in March. The ring of sea ice around the Antarctic continent behaves in a similar manner, with the calendar flipped: it usually reaches its maximum in September and its minimum in February.

This winter, a combination of warmer-than-average temperatures, winds unfavorable to ice expansion, and a series of storms halted sea ice growth in the Arctic. This year’s maximum extent, reached on March 7 at 5.57 million square miles (14.42 million square kilometers), is 37,000 square miles (97,00 square kilometers) below the previous record low, which occurred in 2015, and 471,000 square miles (1.22 million square kilometers) smaller than the average maximum extent for 1981-2010.

“We started from a low September minimum extent,” said Walt Meier, a sea ice scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “There was a lot of open ocean water and we saw periods of very slow ice growth in late October and into November, because the water had a lot of accumulated heat that had to be dissipated before ice could grow. The ice formation got a late start and everything lagged behind – it was hard for the sea ice cover to catch up.”

The Arctic’s sea ice maximum extent has dropped by an average of 2.8 percent per decade since 1979. The summertime minimum extent losses are nearly five times larger: 13.5 percent per decade. Besides shrinking in extent, the sea ice cap is also thinning and becoming more vulnerable to the action of ocean waters, winds and warmer temperatures.

This year’s record low sea ice maximum extent might not necessarily lead to a new record low summertime minimum extent, since weather has a great impact on the melt season’s outcome, Meier said. “But it’s guaranteed to be below normal.”

In Antarctica, this year’s record low annual sea ice minimum of 815,000 square miles (2.11 million square kilometers) was 71,000 square miles (184,000 square kilometers) below the previous lowest minimum extent in the satellite record, which occurred in 1997.

Two members of the Climate Change Authority have resigned, with one accusing the government of being beholden to rightwing, anti-science “extremists” in its own party and in the media.

John Quiggin told Guardian Australia he informed the federal minister for environment and energy, Josh Frydenberg, of his resignation on Thursday. It follows the resignation of fellow climate change authority member, Danny Price, who quit on Tuesday.

“The government’s refusal to accept the advice of its own authority, despite wide support for that advice from business, environmental groups and the community as a whole, reflects the comprehensive failure of its policies on energy and the environment,” Quiggin said.

“These failures can be traced, in large measure, to the fact that the government is beholden to rightwing anti-science activists in its own ranks and in the media. Rather than resist these extremists, the Turnbull government has chosen to treat the vital issues of climate change and energy security as an opportunity for political point-scoring and culture war rhetoric.”
