JBowyer, South of Greenland there is a body of extra cold water. Some questions are how did it get there, what impact is it having, is the AMOC slowing down?

Elsewhere, in lower latitudes to the cold area, the North Atlantic Ocean is quite warm, as is the Pacific. In relation to the PDO the question is whether the temperature of the Ocean is higher than previous PDO events. For the last few years waters from California to Alaska have been termed "the blob" through showing anomalous warmth. Many marine creatures died as a result; a huge algal bloom has been a feature.

As discussed above, increased temperature is a feature of the climate as indicated above, it had been acknowledged by ExxonMobil scientists in the 1970s. Permafrost does not thaw unless there is a constant higher than normal temperature, the top surface of ice sheets do not melt without a higher than normal temperature. More moisture carried in the atmosphere allows for larger deluges than previously experienced; for example, Mount Pleasant in South Carolina received 26.88 inches of rain between the 1-4 October. Further inland, Greer received 6.33 inches of rain in the same period.

Quote, from source provided above:

"EXTREMELY HIGH MOISTURE WILL BE ASSOCIATED WITH THIS SYSTEM PARTLY BECAUSE OF MOISTURE FROM THE TROPICAL PACIFIC AND HURRICANE JOAQUIN OFF THE SOUTHEAST COAST. FORECAST MODELS HAVE BEEN CONSISTENT DISPLAYING AN EASTERLY 50-KNOT LOW-LEVEL JET ABOUT 5000 FEET ABOVE THE SURFACE FEEDING TROPICAL MOISTURE INTO OUR AREA. THE PATTERN SUPPORTS HEAVY RAIN WHICH MAY BECOME EXTREME WITH PARTICULARLY DANGEROUS FLASH FLOODING RESULTING."

Sadly, the models used by Meteorologists have been far too accurate.

Ant I have been fishing for over fifty years and in fact have a little dam in my back garden so I observe water all the time. It is never still. It is always moving. Moving means temperatures will change. In fact as water warms and cools it moves up and down, simple physics.
A blob of water?
When anyone but you nutjobs talk about an "event" (heavy rain) we are accused of confusing climate with weather. So my confused friend have another cuppa and the increased ice in the Ice Age, from what I have read, was confined to the Northern Hemisphere.

JBoy
thanks for the tea. Tasmania, Oz Alps , Argentina and cruise ships in Antarctica had an Ice Age. Your dam had frost on it and the Roaring Forties were nippy.

Oh Nurse! Nick has got out of bed again.
Back to beddie Byes Nick and leave thinking to the grown ups.

"increased ice in the Ice Age, from what I have read, was confined to the Northern Hemisphere."
Just 1 nice grown up site or reference, oh abusive one.

JBowyer, pull your head in you silly twat. People are laughing at you.
