The ice is melting. Faster than ever before. That is not a prediction. It is an observation. The ice takes longer to reform each winter. Another observation. Polar bears are coming into contact with Kodiak or Brown bears in Alaska when that used to hardly ever occur in the past (due to a lack of an ice barrier). Another observation. The melted ice will raise sea levels, just as when there is an abundance of ice the sea levels drop concurrently. Yet another observation. The only 'prediction' that I will make is that the trend will not reverse on its own. It will require direct action. Not political fighting.
'The ice', whatever you mean by that, is not melting as fast as the models predict. Ice in some places is even growing.
The question is not whether climate change happens, of course it does. The questions are: what causes it, how much of what causes it is human, and what are the things that we do that contribute to climate change and by how much? These questions are the ones that the models are failing to accurately predict. That makes the whole issue difficult.
Example, if the models predict that an increase of x% in the output of Q will result in a temperature change of T and we see an increase greater than x% in the output of Q and the temperature change is less than T, then we know that the models are flawed.
Have you ever looked into the issue of sensitivity for example? This is a measure of how much the climate will change due to a change in output.
If the models keep predicting that changes CO2 will result in a certain increase and it does not happen, then we need to look at the models. We need to determine if the 'problem' is being caused by CO2 before we politicize the issue and start taking actions that can cripple the economy.
Incidentally, climate change could potentially work out very well for us in the long run. It is not necessarily a problem. It could just be a short term inconvenience.
I am not saying that man-made changes to the climate are negligible. I am not saying that they won't cause severe problems. I am just saying that it is not as cut and dried or as decided as a lot of people like to think.
