Students and youth groups in Aberystwyth and Borth today took part in the worldwide 350 campaign. The campaign is aimed to highlight the 350 parts per million judged by scientists to be the safe upper limit for carbon dioxide in the atmosphere. The current figure is 390. The event is being held across 181 countries today ahead of the UN Climate Negotiations in Copenhagen in December.
