Thunberg expects 'meaningless' pledges at COP26

The COP26 summit, taking place next month in Glasgow, Scotland, aims to secure pledges by the world’s nations to limit the global temperature from rising more than 1.5 degrees Celsius above the preindustrial average.

In just three years since she started skipping school on Fridays to protest alone outside the Swedish parliament, Thunberg has become a global figure, giving voice to her generation's fury at the world's failure to tackle a problem known about for decades.

Next month's COP26 summit is billed as the last big chance for leaders to announce firm targets to cut climate-warming industrial emissions this decade. Thunberg says she will probably go to the conference, but expects to be disappointed once again.
