The upcoming COP26 UN summit in Glasgow must secure serious collective action to address the climate crisis. Failure could spell the loss of entire low-lying Pacific nations, and we can only fail if we shirk our responsibilities.

We have reasons to be hopeful. Momentum for action is growing. Since the Fijian presidency of COP23 in 2017, more than 100 countries have pledged to achieve net zero emissions by 2050, and many wealthy nations have strengthened their Paris targets for reducing greenhouse gas emissions by 2030.
