Human behaviour crisis drives earth overshoot
(Reprint from The Guardian)
Record heat, record emissions, record fossil fuel consumption. One month after Cop28, the world is further than ever from reaching its collective climate goals. At the root of all these problems, according to recent research, is the human “behavioural crisis,” a term coined by an interdisciplinary team of scientists.
“We’ve socially engineered ourselves the way we geoengineered the planet,” says Joseph Merz, lead author of a new paper which proposes that climate breakdown is a symptom of ecological overshoot, which in turn is caused by the deliberate exploitation of human behaviour.
“We need to become mindful of the way we’re being manipulated,” says Merz, who is co-founder of the Merz Institute, an organisation that researches the systemic causes of the climate crisis and how to tackle them.
Merz and colleagues believe that most climate “solutions” proposed so far only tackle symptoms rather than the root cause of the crisis. This, they say, leads to increasing levels of the three “levers” of overshoot: consumption, waste and population.
They claim that unless demand for resources is reduced, many other innovations are just a sticking plaster. “We can deal with climate change and worsen overshoot,” says Merz. “The material footprint of renewable energy is dangerously underdiscussed. These energy farms have to be rebuilt every few decades – they’re not going to solve the bigger problem unless we tackle demand.”
“Overshoot” refers to how many Earths human society is using up to sustain – or grow – itself. Humanity would currently need 1.7 Earths to maintain consumption of resources at a level the planet’s biocapacity can regenerate.
Where discussion of climate often centres on carbon emissions, a focus on overshoot highlights the materials usage, waste output and growth of human society, all of which affect the Earth’s biosphere. … Continue Reading
