Researchers urge governments to help worst afflicted countries, such as Nigeria and Algeria, which rely on oil revenues for public services

Conflict, migration and economic upheaval will accompany the global move away from oil, unless governments act urgently to help the worst afflicted countries to cope, research has found.

Nigeria, Iran, Angola and Algeria are among the countries that will be severely affected, as they rely strongly on oil revenues for their government and provision of public services, but have little diversification and too little capital to cushion the blow.

As well as being quieter, cheaper to run and easier to clean, induction cookers can cut kitchen temperatures by up to 10C

Leaping flames, searing heat, copious sweat and scorchingly inventive swearing – restaurant kitchens are never a place for the faint-hearted, but this summer they have been sweltering in successive heatwaves to a dangerous degree.

Some restaurants, cafes and bakeries in the UK grew so hot that they were forced to close, or reduce their hours, for the safety of their staff. There is still no maximum working temperature, despite calls from the TUC, and tens of thousands of kitchen staff are thought to have carried on working in “furnace-like” conditions.
