Climate change In 2006, the public, politicians and industry have all shown significant signs that tackling global warming is on the agenda after scientific studies showed the pace of change gathering speed. John Vidal reports: Not before time, the west awoke in 2006 to the vast economic, political and social implications of climate change - and twigged that it presented as many opportunities as threats to humanity. As temperature and rainfall records tumbled, and unseasonal, intense heatwaves, droughts and floods struck many countries, local and national politicians scrambled to beef up their green policies and credentials, some businesses found they could make a packet from trading carbon, and a broad-based global social and ecological movement emerged, linking climate change to social justice, as well as to poverty and lifestyles.
