THE head of this year’s United Nations climate talks called today for governments and businesses to tackle global warming by reducing greenhouse gas emissions in all regions and sectors.

Sultan al-Jaber said that urgent action was needed if world leaders want to stop the planet from passing a key temperature limit agreed on more than seven years ago.

Mr Jaber of the United Arab Emirates, who also heads one of the country’s state oil companies, told senior officials from Europe, Canada and China gathered in Brussels that record-breaking heat seen across the world recently shows the need for urgent action to curb emissions.
