How is cutting emissions different from preparing for floods?

Reducing the causes of climate change and reducing harm from its effects solve related but different problems. A hypothetical town might cut emissions from its buildings while improving flood warnings. Calling both actions climate policy is reasonable, but their purposes, timescales, and measures of success differ.

Why can a city be warmer than nearby countryside?

The trip from a leafy edge of town to a dense street can also be a trip between different temperatures. Buildings, pavement, vegetation, and waste heat all affect the balance, and the contrast changes with weather and time of day.

A trip through a wastewater treatment plant

Water disappearing down a drain begins another journey before it reaches a river or the sea. Uisce Éireann's description of treatment in Ireland separates several different jobs, from screening out objects to biological treatment; the resulting effluent is not drinking water.
