Pressure is growing on leaders of the G7 club of rich nations to provide more funding to deal with climate change and surplus COVID-19 vaccines for developing countries as an act of global solidarity when they meet this coming weekend in Britain.
Green groups, development agencies and international policy experts said those gestures would be effective in building trust ahead of November's COP26 climate talks in Glasgow, seen as crucial to putting the 2015 Paris climate accord into practice.
But persuading G7 leaders to dig deeper has been further complicated by Britain's decision to temporarily cut its overseas aid budget due to COVID-19 economic woes, even while doubling its climate finance in the next five years.
