Six months to Cop28: will the most vital summit yet make meaningful progress?

Every year, the world’s leaders gather for the UN climate change
conference. At Cop28, they will be faced with two stark warnings
from scientists: we are likely to breach 1.5C warming above
pre-industrial levels in the next five years, and we are on course
to reach 2.7C of warming by the end of the century. Progress has
never been more critical and this year it lies in the hands of the
United Arab Emirates, a country that has plans to expand its
already extensive oil and gas productions. With six months to go,
Madeleine Finlay talks to environment correspondent Fiona Harvey
about Cop28’s hosts and president, why this year is particularly
key, and how close we are getting to irreversible climate tipping
points. Help support our independent journalism at
