Dear friends, I'm writing to you with an urgent message as the Prime Minister of Tuvalu: Our country is sinking! My homeland could be one of the first nations to be wiped off the map due to climate change. But we won't give up. We will fight! In a few hours, I'm addressing the climate summit in Egypt to call for a new global treaty to phase out fossil fuels and help vulnerable countries cope with climate devastation. Join my urgent call to world leaders now!
