Global warming powered an empire that dwarfed the Vikings

In the Cauvery Delta — the empire’s heartland — this favorable climate transformed the region into the “Rice Bowl of the South.” Three harvests a year became common. Granaries overflowed. Revenues surged.
That surplus freed labor from subsistence farming and redirected it toward imperial ambition. Chola trade guilds thrived, exporting textiles, spices, and grain to the Chinese Song Dynasty — another civilization that prospered during this warm epoch.
Today, we find ourselves in another warming phase, emerging from the depths of the Little Ice Age that ended in the mid-19th century. Global crop yields have repeatedly reached record highs. India has re-emerged as a major grain exporter. The planet is experiencing a measurable “greening” effect as higher atmospheric carbon dioxide levels fertilize plants and warmer temperatures expand cultivable land.
Yet, we are told to feel guilty.
Coal, oil, and natural gas — fuels that protect humanity from the elements and power modern economies — are vilified. Environmental extremists implicitly argue for a colder world, despite the historical record showing that colder periods brought famine, disease, and social collapse.
The Chola Empire stands as a reminder of what human ingenuity can achieve when the climate cooperates. Its ships sailed on prosperity sustained by warmth. Its temples rose from a society rich in calories and confidence. Its civilization commanded respect across continents.
We face a similar opportunity today. A modern golden age remains within reach — provided we do not cripple ourselves with fear of the very conditions that have so often underwritten human prosperity.
