Stupid strawman argument. No one denies the climate changes.
Smart people think you’re idiots for thinking today’s climate is optimum and thinking you can control the weather.
So climate changes and you propose to do...?
Today’s climate is optimal, for us, since we tend to build our ports where the water currently meets the land. Actually we can control the weather and have been for millennia. Burning forests to promote grassland is one example. Cutting down forests and changing the land into a desert is another.
