Case study: Climate change in Barbados
The 2009 Junior 8 team investigate the effects of climate change on the island's coral and wildlife.

Copenhagen Climate Change Forum
Four young people were selected to attend the Children's Climate Forum hosted by UNICEF and the city of Copenhagen in December. Along with other children from around the world they drew up a declaration with recommendations on how governments can take action on climate change.
Children and climate change
Boys carry containers of water that they have collected from a well in the remote, mountainous village of Dora in Djibouti. The UNICEF-provided well is the only source of water for the village, where it has not rained for three years.

Did you know that the average UK citizen releases the same amount of carbon dioxide (CO2) in 2.5 days as a Malawian does in a year?
Last year, UNICEF UK released a report highlighting the serious impact climate change has on children and their rights, and calling for the UK government to make children a priority on the issue.
To combat this global crisis, UNICEF is helping children in the countries most vulnerable to climate change, by helping them to prepare for and respond to the increase in natural disasters, providing clean water and disease protection, and enabling the concerns of children to be heard by decision makers. UNICEF UK is working to raise funds for this, as well as joining other organisations to call for political action on climate change.
What is climate change?
The climate of the earth is always changing, and in the past this has been due to natural causes.

Climate change refers to the recent (in the last 50 years or so) massive rise in average global temperature as a result of human activity.
This rise in temperature has been attributed to greenhouse gas emissions from a huge increase in fuel use. Carbon dioxide is one of the main greenhouse gases, and is caused by the burning of fossil fuels like coal, oil and gas, and chopping down trees.
Nearly half of UK emissions are due to individual people's actions (such as transport, energy and food choices).

The effects
Some of the effects of climate change can already be seen. In the UK, spring is arriving earlier, summer is drier and the rise of sea levels is eroding the coastline. Globally, sea levels and temperatures are predicted to rise further, and extreme weather is likely to become more frequent.
A 4°C rise in global temperature could lead to up to 300 million more people suffering from coastal flooding each year as sea levels rise, most of them in developing countries.
Natural disasters such as floods and hurricanes will become more frequent, and higher temperatures could lead to the spread of diseases such as malaria to regions that are not prepared to deal with them.
Extreme weather can also lead to droughts and famine in developing countries. The World Health Organization estimates that each year 150,000 lives are already being lost as a direct result of climate change.
