I was referring to lyings icy lighthouse photo . . . we do have good friends down where you are now (Whitianga). They planned on moving back but love it there so stayed, enjoy!

ahhh North Island. I am about 135 km south of Christchurch in Geraldine, South Island. I may stay as well.

Mtn bike heaven...

You gotta take a spin on some of the trails out of Christchurch, I've heard there monumental.....

You reckon it's all melted since then.

Why not listen to what scientists have to say about it?

"If the Southern Ocean is warming, why is sea ice increasing? There are several contributing factors. One is the drop in ozone levels over Antarctica. The hole in the ozone layer above the South Pole has caused cooling in the stratosphere (Gillet 2003). A side-effect is a strengthening of the cyclonic winds that circle the Antarctic continent (Thompson 2002). The wind pushes sea ice around, creating areas of open water known as polynyas. More polynyas leads to increased sea ice production (Turner 2009).

Another contributor is changes in ocean circulation. The Southern Ocean consists of a layer of cold water near the surface and a layer of warmer water below. Water from the warmer layer rises up to the surface, melting sea ice. However, as air temperatures warm, the amount of rain and snowfall also increases. This freshens the surface waters, leading to a surface layer less dense than the saltier, warmer water below. The layers become more stratified and mix less. Less heat is transported upwards from the deeper, warmer layer. Hence less sea ice is melted (Zhang 2007).

Antarctic sea ice is complex and counter-intuitive. Despite warming waters, complicated factors unique to the Antarctic region have combined to increase sea ice production. The simplistic interpretation that it's caused by cooling is false."

That's a bit deep for these parts round here . . .

Looks a bit too shaley for me. Prefer nice hard pack but if you're running 29's with 2.5's on a plush ride then that could be fun. The scenery is amazing and the people are really friendly .

I remember when people smarter then those on this forum claimed without a doubt that eating fatty foods causes heart disease...

How much warmer is the ocean in the arctic?
If the simplistic interpretation that cooling causes more ice is incorrect in the antarctic, then why is the simplistic version of warming causing less ice in the arctic correct?
