LONDON, April 13 (Thomson Reuters Foundation) — Climate activist Greta Thunberg this week said she would skip the United Nations climate conference due to be held in Scotland in November over concerns that inequality of access to COVID-19 vaccines will leave many countries unable to attend.

Thunberg shot to fame in 2018 when she began a solitary protest against global warming outside the Swedish parliament in Stockholm, skipping her Friday school classes to demand her government take action on climate change.

Here is a timeline of Thunberg's rise from a solo climate striker to a global campaigner against COVID-19:

Aug. 26, 2018: She is joined by fellow students, teachers, and parents at another protest and begins attracting media attention for her climate campaign.
