Youth activist leaders from around the globe gathered in Stockholm, Sweden, ahead of their journey to the United Nations climate summitwhere they will let their voices be heard.

Thousands of people marched in the city on Friday for the last Global Climate Strike before the 2021 Climate Change Conference, COP26, opens in Glasgow, Scotland.

People planned strikes in more than 500 locations around the globe, organized by Fridays for Future, a youth climate movement started by Swedish activist Greta Thunberg. She said that she was fearful that Glasgow would not provide the action needed to solve problems. However, youth activists¡® presence from around the world would remind politicians that their actions were being scrutinized.

The activist added that young people were watching the world leaders, and they were not going to let them get away with just talking, doing nothing and only pretending that the situation was under control.

Difficult words: activist (a person who works to change politics or society), climate summit (a conference where world leaders discuss how to prevent the rising of world¢¥s temperature), scrutinize (to examine something very carefully and thoroughly).
