I thought you wouldn't understand, whether by design or otherwise.

Read about polar amplification.

Google jet streams.

Get a PhD in science so you can develop your views on phytoplankton so they have some rigour, your views are interesting but nothing more.

ant,

How about you just answer the question I asked?
Better still, perhaps you could provide scientific evidence of the answer.

Think about the question and answer it. I reiterate.

If warming caused by CO2 is GLOBAL, why is there a greater and more consistent degree of warmth in the region of Greenland but not in Australia and New Zealand?

JK Aus

I've suggested you research the answer, and gave suggestions.

But, for decades scientists have stated that warming would be greatest at the Poles.

The question is; JK Aus, are you a denier in another guise, or do you really believe in the impact of algae on climate?

If it is the latter you would research the suggestions made.

WARMING GREATEST AT THE POLES?

Guess that explains expanding sea-ice in Antarctica - and why southern Australia (Adelaide, Canberra, Melbourne, Hobart) has had its chilliest July/winter in almost two decades – and first snow in Hobart since 1986.

"The June 2015 Southern Hemisphere sea ice extent was 14.93 million square km, 1.00 million square km (380,000 square miles), or 7.18 percent, above the 1981-2010 average. This was the third largest Antarctic sea ice extent on record, only smaller than the June sea ice extents of 2010 and 2014. There was slightly above-average sea ice in every region of the Antarctic, with much-above average ice in the eastern Waddell and Ross Seas. June 2015 is the fourth consecutive June with above-average sea ice extent in the Southern Hemisphere."

What we seem to have here, Watson, is an unfalsifiable hypothesis. Whether Antarctic sea-ice extent decreases or increases, both outcomes are interpreted as evidence of warming.

An ugly business. The more I see of it, the less I like it.

Prior to 1980 snow on the summit of Mount Wellington was a fairly frequent occurrence.
For a couple of ski seasons it was possible to ski in October prior to 1980 at Mt Mawson.
It is definitely very unusual for Hobart itself to have snow, right down to beach level.

Last year the Eastern States of the US were inundated by huge snowfalls; yet, the Western States received much less than usual in 2014. The global temperature still showed an increase. For an explanation on temperature view retired Admiral Titley's explanation above about how satellite reading of temperature is not as accurate as from land based weather stations..

The Arctic and Antarctica are quite different; comprising sea ice and land locked snow respectively. In relation to Antarctica it is not a simple linear point about ice is expanding therefore. Scientists are telling us about the grounding line at the end of glaciers being undermined by water underneath. Fresh water freezes at a higher temperature than denser salt water.
All interviews I have seen with glaciologists state that anthropogenic climate change is happening; please provide references to any glaciologist who have stated otherwise in 2015.

An interesting eventuality:

EVIDENCE

http://joannenova.com.au/2015/12/giant-blob-of-superheated-rock-under-west-antarctica/

"A new seismic survey shows there is a blob of superheated rock 60 miles below West Antarctica. To describe it, the researchers use the phrase “like a blow-torch”. Of course, just because the parts of Antarctica that are warming are near or over this hot blob does not mean it’s causing the melting. It could be a coincidence. ; -)

… this is the first detailed look at the Earth beneath this region.

Not surprisingly, the maps show a giant blob of superheated rock about 60 miles beneath Mount Sidley, the last of a chain of volcanic mountains in Marie Byrd Land at one end of the transect. More surprisingly, they reveal hot rock beneath the Bentley Subglacial Trench, a deep basin at the other end of the transect.

The Bentley Subglacial Trench is part of the West Antarctic Rift System and hot rock beneath the region indicates that this part of the rift system was active quite recently.

The study really highlights how little we know about heat flow in Antarctica:

While heat flow through the Earth’s crust has been measured at at least 34,000 different spots around the globe, in Antarctica it has been measured in less than a dozen places. In July 2015, scientists reported the heat flow at one of these spots was four times higher than the global average.

Ever since then, scientists have been wondering why the reading was so high. “Recent extension in the Bentley Subglacial Trench might explain these readings,” Wiens said.
