IPCC’s latest recommendations based on dangerous “magical thinking”: observers
OCT 31, COPENHAGEN — It’s hallowe’en at the Intergovernmental Panel on Climate Change (IPCC)’s 40th plenary session, but as the world’s premiere climate science body releases its latest report, observers are wondering if the planet has been played a very nasty trick indeed. The IPCC appears to have embraced carbon geoengineering in the form of CCS and BECCS (Bioenergy with Carbon Capture and Storage), which it now claims can achieve “net zero emissions” somewhere in the second half of the century. But critics are calling the move a case of dangerous “magical thinking”.
“IPCC’s AR5 synthesis report doesn’t quite say that a herd of magical unicorns can save the climate, but it may as well have,” said Neth Dano, Asia Director for ETC group. “Frankly, based on what we know about unicorns and BECCS, magical unicorns are a kinder bet to reduce the carbon in the atmosphere.”
“BECCS is magical in the worst way: it likely won’t work, and it’s leading climate policymakers down a dead-end road that gives oil companies an excuse to keep pumping CO2 into the atmosphere.”
Reuters reported on October 31 that a permissive approach to “overshoot” is a theme emerging from the AR5 report. This thinking proposes that countries can exceed their emissions targets on the risky assumption that new technologies will be invented in the years to come that will mop up excess carbon from the atmosphere. This “pollute now, clean up later” principle is a radical departure. Previous IPCC reports more sensibly recommended reducing emissions enough to keep global levels of atmospheric carbon within safe limits.
BECCS, which is largely a hypothetical technology, is the poster child for this new “overshoot” approach. It is part of a suite of imagined geoengineering approaches called Carbon Dioxide Removal (CDR) techniques. The hype surrounding BECCS provoked at least one media outlet to declare last year that “burning trees 'may help reverse global warming'.”
The idea behind BECCS is to grow trees and other biomass (which will absorb carbon) and then burn that in special power plants that capture the carbon emissions before they escape into the atmosphere. In this way, energy can theoretically be generated with “net zero” emissions, and even take CO2 out of the atmosphere.
Critics have poked many holes in the concept:
- Where would billions of tonnes of captured carbon be stored? The likely destination would be “enhanced oil recovery” techniques, increasing, not decreasing, the flow of fossil fuels that cause climate change.
- To reduce overall CO2 by 1 billion tons using BECCS would require a landmass of 218-990 million hectares of land which is 14-65 times as much land as the US uses to grow corn for ethanol. This would requiring landgrabbing on an enormous scale.
- BECCS proponents assume that 10 billion tonnes of wood can be harvested per year without any carbon from soil or ecosystems escaping into the atmosphere. And yet, land use change and emissions from soil are widely acknowledged as leading drivers of climate change.
- Today, the only schemes that are labelled as BECCS extract CO2 from biofuels such as ethanol, tying this scheme to their many associated problems, starting with land grabs and food price hikes.
- Would the hundreds of billions of tonnes of stored carbon leak into the atmosphere or pollute local ecosystems?
“The fossil fuel lobbyists are likely popping champagne after this move,” said Pat Mooney, ETC Group’s Executive Director who was in Copenhagen for the IPCC plenary. “The fossil fuel lobby has 55 trillion dollars in infrastructure and 28 trillion dollars in investment to defend.”
“They would rather have governments chasing after BECCS, unicorns or anything else instead of taking meaningful action to reduce fossil fuel use,” Mooney added. “By redirecting attention toward these magical nonexistent technologies, they hope to send the climate negotiations on a long and costly technological snipe hunt.”
“By reccomending a nonexistent technology and using it to justify emissions ‘overshoot," the IPCC risks undermining its own credibility,” said Jim Thomas, Programme Director of ETC Group. “This is dangerous territory, because the IPCC is a globally-respected reference point for policymakers–the IPCC report is strong on the effects of climate change and the need for action, but lending support to BECCS is a step backwards.”
“If we lose the IPCC to corporate magical thinking fuelled by a cash-rich oil sector, it would set back efforts to reduce climate emissions by decades,” Thomas added. “Adopting BECCS could also pave the way for other crazy geoengineering schemes such as shooting sulphur dioxide into the atmosphere.”
