Your problem is that you don't have the background to understand the issue itself and just take misreadings and misleading from others. Try to think of it yourself.

And note that the scientists don't say that there is a significant change in AGW. They just say that the chart of air temperature has 'paused' but that it is 'statistically insignificant'. Two disconnects from saying that AGW has stopped. One is that it is a chart of AIR temperature at two meters (meterology data), not the SURFACE. And any chart is based on incomplete information. The 'pause' in the HADCRUT data is larger than any other because it misses the heat that flows to the polar regions (inadequate coverage of polar sites). And all of them miss the increased heat in the deep ocean because they don't incorporate total thermal content.

AGW is the 'rise in global average surface temperature'. Now to debate this you need to understand what the 'surface' is and how much of it is warming and where. Obviously the sun warms the 'surface' over land and ocean and this energy is then convected to the air (this is the basic physics of solar isolation). The heat that affects the land and ocean then must be conducted to deeper layers before an equilibrium can occur. Science shows from boreholes that the 'surface' on land is affected to about 150 meters. In the oceans the 'depth' is more variable since there is a lot more mobility but it is at LEAST 600 meters of ocean that must be warmed to change 'surface' temperature.

This is where the 'insigificance' of the proxy meterology chart is determined. The land interface is pretty solid but the oceans can have 'upwellings' and 'downwelling' currents that bring a different temperature ocean mass to the air interface. Most of these are driven by 'climate oscillations' that have about a ten year period. So to prevent aliasing of the data you need about THIRTY years of air temperature anomaly before the air temperature is a valid proxy for what is happening to the SURFACE. It is almost guaranteed that LaNina will turn to an ElNino and have a high value before another ten years is passed like 1998.
