The amplitude of the pattern defined by the leading empirical orthogonal function of
winter monthly mean NH MSLP anomalies poleward of 20 ° N (Thompson and Wallace, 1998, 2000).
The warming trends in looking at numerous 100 year temperature plots from northern and high elevation climate stations... i.e. warming trends in annual mean and minimum temperature averages,
winter monthly means and minimums and especially winter minimum temperatures and dewpoints... indicate climate warming that is being driven by the accumulation of greenhouse gases in the atmosphere — no visible effects from other things like changes in solar radiation or the levels of cosmic rays.
