This is how big one tonne of CO2 is

Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
At standard temperature and pressure (STP) it looks like CO2 has a density of 1.96 kg/m^3. 1 tonne = 1000 kg, so a tonne of CO2 has a volume of (1000 kg)/(1.96 kg/m^3) = 510 m^3 at STP. A cube of that volume would have side length (510 m^3)^(1/3) = 7.99 m, so roughly 8 meters per side.
I don't know how tall that person is, but if we assume around 1.6 m (5' 3") then the cube side length should be about 5 of her. Seems pretty accurate to me.
Thank you, this helps, brain wrapping successfully now.
