Glossary
Queen Victoria - The Queen of the United Kingdom of Great Britain and Ireland from 1837 to 1901. Her reign is known as the Victorian era.
Greenhouse gases - Greenhouse gases, which increase the atmosphere's capacity to hold heat, are vital to life on Earth: without them the planet would be freezing. But human activity is disturbing the delicate balance that created the conditions for life as we know it. Carbon dioxide is responsible for 60% of the manmade greenhouse effect, but we also produce smaller quantities of methane, ozone and nitrous oxide, which are even more damaging.
Carbon dioxide - Carbon dioxide is a colourless gas formed during the combustion of any material containing carbon and is a significant greenhouse gas.
Methane - A particularly strong greenhouse gas produced by fossil fuels and cattle.
