That is silly because no one ever based any predictions on computer models.
We use computer models only to help us understand what already is happening.
Sorry guy, but the entirety of climate science and their predictions are based on computer models...Which is why I can state with perfect confidence that there is not a single shred of observed, measured evidence which supports the man made climate change hypothesis over natural variability....I can say it knowing without a doubt that no one will post any observed, measured evidence to contradict me because no such evidence exists...it is all computer modeling and it has littered the scientific landscape of the past 40 years with failed predictions.
And clearly the oceans, glacial and polar ice, are much warmer.
The British Admiralty noticed global warming over 100 years ago, because they were carefully measuring ocean temperatures in order to map currents.
Warmer than what? Warmer than it was during the little ice age and the early days when the earth was just exiting it? Duh? Of course the oceans and the climate were colder during that cold period. Is it warmer than it has been for most of the past 10,000 years? Not even close. Here, have a look at the gold standard (according to climate science) in temperature reconstructions of the past 10,000 years. It was derived from the GISP2 ice core extracted above the arctic circle in Greenland. It is the most pristine record of temperatures over the past 10,000 years that we have and according to it, it is colder now than it has been for most of the past 10,000 years except for the little ice age...
As you can see, the present is considerably cooler than it has been for most of the past 10,000 years. And you can also see that during the past 10,000 years, there have been temperature increases far greater than anything we have seen in a much shorter time than any changes we have seen...and temperature decreases that were both greater and faster than any that we have experienced... Today, it isn't even as warm as it was prior to the onset of the little ice age...what would make you think that it would't get at least that warm if not as warm as it was during the roman period...or the minoan period, or the holocene optimum? If you look closely at that graph, you see a cooling trend... You really should hope that it continues to warm...we know from the past that warm periods were great for life on earth....cold periods, however are killers.
If you look at things in history, like the USS Nautilus crossing under the North Pole in 1957, you will see that even in summer, there was no open water for a Northwest Passage, and it could only be traversed by submarine.
Now there is open water route across the pole, in summer.
It has changes tremendously.
Tell me...what do you think happens to ice as a planet exits a cold period? Here, have a look at a reconstruction of the arctic ice over the past 10,000 years...As you can see, except for the ice growth during the little ice age, there is more ice in the arctic now than there has been for the past 10,000 years. There have been periods in the past 10,000 years when it is likely that there was no ice to be found in the arctic at all during the summer months. You guys seem to think that the climate isn't supposed to change...ever...that it is supposed to remain static just because we are here. As you can see, we haven't even reached the temperature it was before the onset of the little ice age...what on earth would make you think that we shouldn't at least warm up to that point, if not the much warmer temperatures you see as you go back to the roman period, the minoan period, and the holocene optimum?
