    Addressing Climate Change Will Not “Save the Planet”

    « Sauver la planète » c-à-d freiner l’extinction des espèces

    Mainstream climate activism of the Bill McKibben variety points toward a grandly hopeful end within the confines of acceptable capitalist discourse: decarbonization of the global economy, with technologies driven by profit-seeking corporations subsidized by governments. Taking up this banner of optimistic can-do-ism, the environmental movement has convinced itself, and sought to convince the public, that with a worldwide build-out of renewable energy systems, humanity will power its dynamic industrial civilization with jobs-producing green machines while also — somehow — rescuing countless species from the brink.

    “But this happens to be a lie,” Ashe told me. “The lie is that if we address the climate crisis, we will also solve the biodiversity crisis.”

    […]

    Yes, a warmed atmosphere is projected to be a significant factor in the #extinction crisis in future decades, but what’s destroying species today is habitat fragmentation and loss, overhunting and overexploitation, agricultural expansion, pollution, and industrial development. It isn’t climate change that caused a 69 percent loss in total wildlife populations between 1970 and 2018, according to a World Wildlife Fund study published this year. The cause is too many people demanding too much from ecosystems, or human overshoot of the biophysical carrying capacity of the Earth.

      Explainer: Can climate change and biodiversity loss be tackled together?
      ▻https://www.carbonbrief.org/explainer-can-climate-change-and-biodiversity-loss-be-tackled-together

      In 2021, the first joint report by the IPCC and IPBES concluded that the world must tackle climate change and biodiversity loss together if either issue is to be successfully solved.

      The group of 50 scientists warned that pursuing solutions narrowly focused on climate change risked harming biodiversity and vice-versa, but that there are many options policymakers can take to tackle both problems as one.

      The graphic below, taken from the IPCC-IPBES scientific outcome report, illustrates how (top) actions to tackle climate change could have positive (blue) or negative (red) impacts on biodiversity and (bottom) how actions to tackle biodiversity loss could impact climate change mitigation.

      [...] As well as demonstrating how some measures could effectively tackle both climate change and biodiversity loss, the diagram (above) also illustrates how some efforts to tackle warming could pose a risk to nature.
