momentum, lol!

 

Oddly enough, it's still there.

But there is just a lot less of it.

Yes it's the same reason that there is less ice in recent northern summers than there was in past northern summers. Its getting warmer.

I checked again, it's still there.
This disappearing process seems to be taking it's time.

Correct.  The Earth has gone through many entirely natural warming and cooling phases throughout its 4 billion years of existence.

Ice Ages end through the Earth warming up, of course.

It's also a fact that, when the Romans were in Britain between 43AD and 410AD its climate was warmer than it is now.  That's why the Romans were able to plant vineyards over wide ranges of their province of Britannia.

Then, from the medieval times to the early 19th Century, Britain was in a period we now call the Little Ice Age, when winters were much colder than they are now.  In fact, during the Little Ice Age winters were so cold in Britain that the River Thames froze over almost every year allowing magnificent Frost Fairs to be held on the London section of the frozen river, the last of which was held in 1814.

But the Little Ice Age came to an end due to the natural warming of the Earth.

The Earth just goes through natural warming and cooling phases and has been doing so since long before humans came onto the scene.

And here are some stats about Antarctica which the Global Warming Brigade wouldn't want to hear:

The temperature record for Antarctica goes back to the 1950s. The record consists of data from a sparse network. Four comprehensive studies were conducted in recent years, collecting temperature data over Antarctica for the period since the 1950s until the 2000s. All of these studies have found slight warming in the earliest portion of the record (circa 1957–1965). Since the mid-1960s, all major studies have reported cooling over most of Antarctica. The only place that exhibits strong warming for the entire record is the Antarctic Peninsula, which amounts to 0.5% of the land mass of Antarctica.

In a paper published in the journal Nature in 2002, Doran et al. reported overall cooling over Antarctica. This study concludes there has been "a net cooling on the Antarctic continent between 1966 and 2000, particularly during summer and autumn.

Chapman and Walsh, (2007) in the paper published by Journal of Climate collected temperature in and around Antarctica from 460 locations including 19 manned surface observation stations located on the continent, 73 automated weather stations, and the 2° latitude by 2° longitude gridded sea surface temperature time series. They found little change in temperature over Antarctica in last 50 years (apart from the Peninsula). From the beginning of record until about 1965 they find slight warming, since 1965 slight cooling: "Trends computed using these analyses show considerable sensitivity to start and end dates with starting dates before 1965 producing overall warming and starting dates from 1966 to 1982 producing net cooling rates over the region."

Monaghan et al. (2008) in the paper published by Journal of Geophysical Research, similarly finds that "prior to 1965 the continent-wide annual trends (through 2002) are slightly positive, but after 1965 they are mainly negative (despite warming over the Antarctic Peninsula)."

Steig et al. 2009 in the paper published by Nature, unlike all other major works, find significant warming trend over Antarctica 1957–2006, of 0.1 C per decade, although Steig's reconstruction agree to greater extent with other studies in showing little temperature change since late 1960s

Frozen Planet was filmed over four years and is thought to have cost over 16 million pounds to produce.  I love watching the show and was interested to know what conclusions David Attenborough had come to during that time about global warming and our contribution to it.  Today I discover that America won’t see the last episode where Attenborough says he thinks we are responsible for the warming of the planet, they pulled it in case it hurt the sale of the series.  Not sure if the same applies to Oz.  Up to this point, he was a dedicated GW sceptic and what this respected icon thinks matters.

I'm not allowed to include the link but it's in The UK Telegraph and interesting reading.
