‘The name’s Brick’ – COVID-19 and Climate Change

  • Reset

Despite the rumours, pandemic-caused restrictions have not been a ‘temporary reprieve’ or ‘silver lining’ for climate change. 

In this infographic, Kiwi science communicator and climate expert John Lang introduces the world to a new climate character: the name’s ‘Brick’. Together, they explain why temporary CO2 emission reductions caused by COVID-19 will not slow down global warming — unless, that is, another set of characters, namely governments, decide to intervene and make the reductions permanent.

So — you might be thinking, why is this relevant to NZ?

Personally, I think it’s a good way to break the issue down for the average Joe. Or for the average Judith. When Greta Thunberg says we have less than 10 years, Judith, she does not mean we have 10 years to save the planet. She means that we have 10 years to take the collective actions necessary to slash greenhouse gas emissions and give humanity a two-thirds chance of maintaining temperatures at about 1.5°C of global warming — the temperature target that science recommends, that countries have signed up to and that people want. 

And, just to clarify, Judith, it is not the planet that’s at risk; the risk is rather, as climate scientist Kate Marvel so chillingly puts it, ‘not about what climate change will do to us, but what we’ll do to each other because of it.’

New Zealand’s Brick

In NZ, the brick we plonked into the atmosphere in 2018 was 79 million tonnes of CO2e. In other words, our country is still putting the equivalent weight of about 1700 Titanics of greenhouse gases into the atmosphere every year. Much of these emissions are of course not just from carbon dioxide (only about 44%), but rather from methane (about 43%) — a much more potent, but much more short-lived greenhouse gas. 

To shrink the brick in NZ, it seems pretty simple. We need to prioritise two things: work out how to decrease the CH4 from the digestive systems of our cows and the CO2 from the cars we drive. But there is plenty of other stuff we could also be doing to help. For climate change, for our economy and for current and future Kiwis.

So in about three weeks, I will write a pre-election piece for Pure Advantage on what has been achieved over the past three years by the Ardern-led Government, but much more importantly, what ‘the right stuff’ for the next government has to look like to live up to our generation’s so-called ‘nuclear-free moment’. To shrink the brick and grow the economy in the Time of Covid. 

Bold decisions and legislation passed by Ardern and co mean our greenhouse gas emissions curve finally starts bending downwards in the mid-2020s. The next government will determine how steeply.
