I havent even seen spring, barely a hint of it actually. The trees gave blossum a few months ago and that was it.
Its been winter the whole way thorough here, especially over the last 3 or so weeks! A walk through town this Christmas was a strange sight, everyone dressed up in coats a beanies looking miserable at the traffic lights waiting to cross the road in icey gales and rain.
My partner who is German noted our temperatures were the same as in Frankfurt which really is having winter.
They can throw Al Gores movie straight into the cheap bin here if you ask me. |

No I wrote it off as disinformation as soon as I heard about. |

I saw Mr Gores movie about 6 months ago, it is full of lies
eg. Peoples of pacific Islands having to move to NZ(or else where i cant quite remember) because of flooding due directly to global warming.
The planet is heated by the sun! nothing else. The major cause of climate heating is moisture in the air not co2 which is produced mainly from agro farmers, but not to worry the earth is homostatic like all things nature and will try to maintain everything at a constant.
Heres one fact I love about the bull about melting ice caps!
"At what temperature does ice melt?" and at what temperature are the polar caps and some of the worlds high mountains? case closed.
Its just cover to introduce a form of tarrifing when we all go "free" trade...also its a means to put the brakes on new forming mega economies (asia)
Another case of dogmatic idiots. |

Nicely summed up satan.
I believe that it is all a part of the Chemtrail coverup as well. With all of the wild weather patterns resulting from technological manipulation of weather systems, global warming is the perfect bull$@#t coverup.
I was watching 3news 4-5 nights ago and the reporters were asking people around NZ on the streets..."What do you think is causing this unseasonal cold weather?"
Most of the answers given were the same..."I think its really cold right now because of global warming" !!!!!
Imagine, living in a world of people who are brainwashed so badly they will contradict themselves with a mantra that makes no sense taught to them by TV Radio and Al (illuminati bumboy) Gore. Seriously, if the planet is warming up, how does that make for record low temperatures all over NZ for summer.
Heres another point, if indeed the icecaps are melting we need not worry about rising sea levels and this is why......
When water freezes IT EXPANDS IN SIZE, i.e for the dummies that means it increases its volume and there is essentially more water if its frozen. Melt that ice and the volume becomes less. Most of the ice at the poles is in/on the water already so if it melts it wont make any bloody diffference.
Thats some science I learnt at primary school, back when schools still taught useful things to kids. |

Hi Smash,
I wouldn't have a clue what's happening with the climate, but there are a couple of points about ice that you make that I would like to comment on.
| Quote: | Heres another point, if indeed the icecaps are melting we need not worry about rising sea levels and this is why......

Quite right, water does expand in volume as it freezes. The problems with ice cap melting don't relate specifically to that issue however.
When Sea Ice (generally, any ice floating in the sea) melts, it does not affect sea levels - its already in the sea. It can however, depending on its origin, affect the density of the sea, as fresh is less dense than salt water at the same temperature. This causes fresh water to literally float on salt water.
The density of ocean water is not globally homogeneous, but varies significantly and discretely. The interaction between temperature and salinity is the engine driving Thermohaline Circulation (or the Global Conveyor), which has a direct effect on atmospheric climate.
Sea Ice can be composed of frozen sea water or frozen fresh water from glaciers.
The term Ice Cap refers to "a thick permanent covering of ice and snow on land" and because it is on land, it is composed of fresh water. Today, ice caps form over 80 percent of the fresh water on earth.
Ice Cap ice meting into the sea or falling into the sea (from glaciers for example) is a transfer of water from land to the oceans and does affect sea levels.
The northern ice cap covering Greenland, Baffin Island and Sptizbergen contains about 3,000,000 cubic kilometres of ice. It has been estimated that if all that melted, ocean levels would potentially rise by 6.5 - 7 meters.
The southern ice cap over the continent of Antarctica contains about 30,000,000 cubic kilometres of ice. It has been estimated that if all that melted, ocean levels would potentially rise by around 73 metres.
I'm not suggesting that we are in danger of the global ice caps completely melting.... but there is plenty of potential there to affect the Thermohaline Circulation and therefore, global climate. |

No such word. Satanzhand, your posts would make for better reading if you took more care with your spelling and grammar....I'm finding them pretty hard going at times :) |

Homeostasis is what I was trying to be so smart about.
My grammer/spelling is poor no doubt about it. It' has been an on going project for me, since I left school not being able to read 15 ish years ago. I'm 32 now. |

satanzhand,

Homeostasis may play a part in determining the degree to which the Earth's ice caps melt and on thermohaline circulation - but what does it have to do with "if indeed the icecaps are melting we need not worry about rising sea levels" - which was smashdracs point? |

| I cant see the ice caps ever completely melting. The place would really have to warm up alot for that to happen. |

I think the point is Homeostasis.
Eg. There is always something melting and something freezing.
The earth is always balancing its self (which we simply are a part of). We can not for the most part control that (well maybe we could to a degree).
Anyway this basic idea controls the temp of the earth, The hotter the equator (the hotest part of the earth) gets the more water evaporates (creating wind) the more water that evaporates the cooler the world becomes. Done issue solved. The poles(meaning polar ice cap/s) will not melt as they can not get hot enough.
Question if you had a block of ice frozen at -40 degrees then raised the temp to -20 degrees how much of that ice would melt?
Global warming or its new name "climate change"(what a joke when does the climate not change) is a have! a trick for more taxing nothing less.
Just another campaign to scare the crap out of people and give them something else to focus on, anything but why they(the people) are some unhappy |

Hi satanzhand,
smashdracs' original statement was:
| Quote: | | "If indeed the icecaps are melting we need not worry about rising sea levels", [coz the ice is already in the sea] |
I pointed out that there's a whole lot of polar ice that isn't in the sea and "if indeed the icecaps are melting" that water would end up in the sea.
To which smashdracs replied:
| Quote: | | I cant see the ice caps ever completely melting. The place would really have to warm up alot for that to happen. |
Your point satanzhand appears to be:
We need not worry about rising sea levels - because the ice caps can't melt due to homeostasis.
I'm not going to dispute that. As I said,
| Quote: | | "I'm not suggesting that we are in danger of the global ice caps completely melting." |
I agree that Earth is most capable of creating an equilibrium. There is no reason to suppose that in doing so however, homeostasis would take place in a perfectly benign environment for humans. The hurricanes we see in the Atlantic each year for example are part of the process of homeostasis. And there is plenty of evidence that the Earth has seen cataclysmic climatic and weather events on a scale that we haven't seen in the recent history of man. (The work of Immanuel Velikovsky on this topic is widely disputed but none-the-less very interesting.)
And to answer the question you posed - it was a bloody interesting one!
| Quote: | | If you had a block of ice frozen at -40 degrees then raised the temp to -20 degrees how much of that ice would melt? |
I'm not sure, but I guess the answer is none, because at atmospheric pressure, water remains frozen up to zero degrees Celsius.
The water would remain in its solid phase as ice, but 0.51 calories of energy per kilogram of ice would be required to raise the temperature each of those 20 degrees Celsius from -40C to -20C. So all that ice at the poles can absorb a hell of a lot of atmospheric heat energy, before it gets even close to melting.
And its a given that melting doesnt occur in an environment where the temperature is constantly well below zero. That's why there is a build-up of ice at the poles over hundreds or even thousands of years.
The freezing and melting occurs at the margins, where temperatures oscillate around zero degrees. Where glacial ice meets sea water for example. |

HA ha!!!! I reckon thats it in a nutshell..... It really is that plain isnt it?
Or have I missed something???

No threat from global warming melting polar ice caps. |
