I have been off-blog due PC crash after Christmas – just finding feet again –
checking a few URL’s – finding lost links It is not viagra generic sildenafil a process of occurring erection only once. This problem may also be genetic but wrong eating habits like eating processed food, junk food, fast food, oily food, viagra in usa and spicy food may be harmful to human body. viagra sale learningworksca.org Another most dangerous thing is that using ED medicines recreationally, while 50 percent men use them with alcohol and illicit drugs. While the general outlook is bright for men with ED, as during impotence, penile organ is left without suitable blood circulation with muscles and tissues tensed. samples of viagra etc. Chart of Antarctic sea ice extent
Can somebody please post the URL to BoM Time Series graphs page ?
Gee with all that ice creeping closer it is a good thing we have BoM & Chris Turney here in Australia to allay our fears of freezing/sarc.

That extra Queensland area worth of ice has a high reflectivity. The ice reflects about 60 percent of the solar heat that hits it but ocean only reflects about 6 percent. Around this time each year we are at perihelion so the solar irradiance is at it’s annual maximum. That means more of our annual total is being reflected. At this time of year the the south of our planet is tilted toward the sun illuminating the Antarctic all day. That means even more of our annual total is being reflected. The Arctic has no effect on reflectivity at this time of year due to it being in 24 hour darkness. The most heat is always radiated from the hottest parts of the planet. So the near El Nino conditions mean the warm equatorial oceans are also losing a lot of heat to space.
Big jump in the extent anomaly in late December.

There is still sea ice north of the Antarctic Circle, a good 500km north of the average extent.

Be interesting to see if we have an early minimum extent like last year.
Two questions that need to be answered.
Can the high deviation of Antarctic Sea Ice be sustained?
Next question (IMPORTANT) what level of high deviation is needed and for what duration of time in order for it to overcome noise in the climatic system and start to influence the temperatures of the S.H.?
Is it a deviation of above +1.50 million sq. km or does it need to be greater and for how long?
“Can the high deviation of Antarctic Sea Ice be sustained?”
The Antarctic was once a tropical rain forest. When Weddell went there…” in latitude 74 degrees 15 minutes, longitude 36 degrees, discovered a sea perfectly clear of ice, and literally covered with birds of the blue peterel kind. The advance of the season unfortunately obliged the voyagers to return, but very interesting conclusions may be drawn from this extraordinary fact. If there be no more land to the southward, the Antarctic Polar Sea is probably less icy than is imagined, and a clear field of discovery lies open to the Pole”

I would like to know what the “normal average long term GROWTH RATE is.
“Glossopteris trees lived in stands as thick as almost a thousand per acre just 20 or 25 degrees from the South Pole, latitude at which today they would have received no sunlight for half the year. This powerful evidence that when they grew the Antarctic was in a semi tropical zone.”

Note also the bit about the tree that was found to be fossilised five years after it was known to be alive.
I have heard stories about fence posts also.
According to both these sites the Blue Petrel does not go that far south.

It should be said that Glossopteris lived hundreds of millions of years ago – in the Permian according to Wiki –

I must admit I thought it was Mesozoic – this BBC article is discussing a late Mesozoic time –
