De volledige oplossing voor klimaatverandering

The full global warming solution
Door Joe Romm, Climate Progress, 10 januari 2011

Stabilizing atmospheric concentrations of carbon dioxide at 450 ppm or lower is not politically possible today — not even close — but is certainly achievable from an economic and technological perspective.

This is what the entire planet must achieve:

Here are additional wedges that require some major advances in applied research to be practical and scalable, but are considered plausible by serious analysts, especially post-2030:

  • 1 wedge of geothermal plus ocean-based renewables (i.e. tidal, wave, and/or ocean thermal)
  • 1 of coal with biomass cofiring plus carbon capture and storage — 400 GW of coal plus 200 GW biomass with CCS
  • 1/2 to 1 of cellulosic biofuels for long-distance transport and what little aviation remains in 2050 — using 8% of the world’s cropland [or less land if yields significantly increase or algae-to-biofuels proves commercial at large scale].
  • 1 of soils and/or biochar– Apply improved agricultural practices to all existing croplands and/or “charcoal created by pyrolysis of biomass.” Both are controversial today, but may prove scalable strategies.
