That is the point, myself nor you or anyone else can prove or disprove anything about the weather because it is ever changing. I am not mixing up weather and climate I would say you are, as weather leads to climate and settled climate is dismantled by unsettled weather. But mans unfluence on the weather and therefore the climate is paltry compared with natural events.
We learn to live with the weather not the other way round.
So technical language and figures can be twisted whichever way you want but no one can predict the weather or the climate.
We can however follow forecast trends but these are always volatile as we have seen this December. And they are short term forecasts.
Yet global warming is backed up by forecasts of weather and climate 40 to 100 years hence. As I said - what tosh.
In any case we are heading to a zero carbon emission world in the coming decades so mans affect on CO2 will be reduced to zero.
