Earth receives more solar radiation per unit area at the equator than at the poles. The resulting imbalance in heat energy results in a vigorous fluid circulation in both the atmosphere and oceans, redistributing the heat around the planet. Heat is transferred via the atmosphere, which mixes globally on a one-year timeframe, and via ocean circulation, which mixes globally on a thousand-year timeframe. Natural climate change, therefore, needs to be considered over timeframes of at least several thousand years. The longest useful series of instrumental weather measurements, from Europe, is only c. 200 years long, so researchers into past climate change must look to long term geological records which, fortunately, Zealandia has in abundance.
