Don’t confuse weather and climate

Human-induced climate change deniers confuse weather and climate.  It’s actually simple…. Climate is the long term average state. Weather is ther short term state.

Climate models predict the average state. Weather models attempt to predict the instantaneous state. Chaos theory has it that instantaneous phenomena cannot be predicted far out. Yet, it does not take a sophisticated model to predict that if humans increase the concentration of an infrared heat-trapping gas, the climate will warm. It’s that simple. The chemistry of CO2, CH4, H2O are sufficiently well established. Climate models have reproduced observed warming. Climate models wiith human chemical transformations of our atmosphere left out have no warming. See below…

    [...] trends should only be deduced from decadal averages or longer, not picking out individual years. Climate and weather represent different time scales. Shown here, the instrumental temperature data are aggregated in other ways, e.g. northern [...]

    it is very evident that climate change is already taking effect in this decade:`.
