Climate demonstration outside the parliament in Stockholm is held two days before the COP in Katowice. Under the heading "Fridays for future”, the demonstration is inspired by 15 year old climate activist Greta Thunberg, from Sweden.
Similar demonstrations are being held at more than 80 cities in Sweden to make their voices heard and demand that politicians take action on the climate and phase out fossil fuels.
