Two hundred visitors who will attend a Royal Society of Chemistry event at the House of Commons tomorrow (26 June) will each be given coloured paper hand fans to underline the hotter times ahead for the world unless scientists and politicians work together to mitigate the threat of climate change.

The fans will be provided when guests arrive at Portcullis House for Parliamentary Links Day (10.30am-12.45pm), an annual event staged by the Royal Society of Chemistry to explore issues of major importance by bringing the scientific and Westminster communities together.

This year's theme is "Earth Air Fire Water: Science and the Global Challenge". Speakers from Government and Parliament include the Rt Hon David Miliband MP, Secretary of State for the Environment, and Alan Duncan MP, Shadow Secretary of State for Trade and Industry.
