They release large amounts of carbon dioxide when generating

They are intermittent and depend on the weather or time of day

They use up finite uranium fuel

They produce long-lived radioactive waste

It keeps all materials in use indefinitely

It wastes land, releases methane and leachate, and loses materials permanently

It produces no greenhouse gases at all

It recovers more energy than any other method

The natural warming that has always kept Earth habitable, with no human input

The extra warming caused by human-added greenhouse gases such as carbon dioxide and methane

The cooling of the planet caused by air pollution particles

The thinning of the ozone layer by CFCs

Rising atmospheric carbon dioxide measured directly and in ice cores, alongside rising temperatures

A steady fall in global average temperatures since 1900

Growing thickness of polar ice sheets each year

A decrease in atmospheric carbon dioxide since industrialisation

Building sea walls to hold back rising seas
