COVID-19 enforced restrictions will dent global CO2 emissions in 2020 compared with 2019. But this decline will not, by itself, put a dent in climate change. To help explain why, we're introducing a new climate character: the name's 'Brick'.

Brick shows us why temporary CO2 emission reductions will not slow down global warming — unless, that is, another set of characters, namely governments, decide to intervene and help emission reductions become permanent.
