Thunberg’s organisation, Fridays For Future, has released the minute-long spot call “Our house is on fire” and is named after the activists’ famed speech at the 2019 World Economic Forum in Davos in Switzerland where she called for a reduction in carbon emissions.

The work of Los Angeles-based Creative Agency FF, the ad shows a family waking up in the morning and getting ready for school while flames spreading around them are completely unnoticed by the parents and children.

The Swedish teenager began her “Fridays For Future” movement in 2018 when she began protesting in front of the Swedish Parliament on that day each week.

Her actions later sparked similar climate demonstrations across the globe.

Thunberg recently said that it was “extremely likely” she had contracted the coronavirus after a recent trip to Central Europe.

Undeterred, she has rallied her supporters to continue the push for climate change despite global lockdowns.

In a tweet, Thunberg urged her followers to “do as the experts say” and “unite behind experts and science” by avoiding gathering in crowds in an effort to “#flattenthecurve” of coronavirus cases around the world.

“We young people are the least affected by this virus but it’s essential that we act in solidarity with the most vulnerable and that we act in the best interest of our common society,” she said.
