The UN climate report pins hopes on carbon removal technologies that barely exist

The planet is on track to exceed very dangerous warming levels, leaving us with fewer and fewer options.

The UN’s long-awaited climate report, released on Monday, offered a stark reminder that removing massive amounts of carbon dioxide from the atmosphere will be essential to prevent the gravest dangers of global warming. But it also underscored that the necessary technologies barely exist—and will be tremendously difficult to deploy.

Global temperatures will continue to rise through midcentury no matter what we do at this point, according to the first installment of the Intergovernmental Panel on Climate Change’s sixth assessment report. How much hotter it gets, however, will depend on how rapidly we cut emissions and how quickly we scale up ways of sucking carbon dioxide out of the air.

Climate scientists say we’ll need to do carbon removal, in part, to balance out the emissions sources we still don’t know how to eliminate or clean up, like flights and fertilizer. The other, more ominous reason is we may well need to pull the planet back after it blows through dangerous temperature thresholds.

The UN report found that greenhouse gases are likely to drive worldwide temperatures at least 1.5 ˚C above preindustrial conditions within the next 20 years, fueling more common and more severe heat waves, floods, and droughts. Once that happens, carbon removal is essentially the only way to bring the climate back to a safer zone, because the greenhouse gas persists for hundreds to thousands of years in the atmosphere. (A last alternative is, perhaps, some form of geoengineering that reflects heat back into space, but that controversial idea presents all sorts of concerns.)

The secret for the panicked is to eliminate (first) all cows and other animals that fart, then all human beings.

I guess barnyard humour in the face of existential threat is one way to go.

Here we go again: New UN ‘IPCC report is apocalyptic, catastrophic’ – ‘It’s really staring us in the face’ – Certain doom unless – we follow UN central planning dictates!

 

Morano: “We already know these reports are designed to scare the world into climate action. (See:Gore admits UN IPCC report was ‘torqued up’ to promote political action – ‘How [else] do they get the attention of policy-makers around the world?’)The UN is now scaring people to vote the way using the UN’s unscientific extreme model-based scenarios!” [Also see the real motivation behind the reports:New UN IPCC report ‘will motivate all nations to deliver urgent emission reductions’ & commit to ‘climate finance’]

Dr. Roger Pielke Jr.: “So this is a BIG problem. The scenarios IPCC admits are unlikely [to] dominate the report w/ 41.5% of all scenario mentions. The scenarios judged most likely under current trends get only 18.4% of mentions. Implausible scenarios (8.5 + 7.0) total 53% of mentions, more than half!” “The literature is heavily biased to extreme scenarios,” Pielke added. 

“From AR5 WG1 to AR6 WG1 the emphasis on 8.5 scenarios increased dramatically,” he explained. “The IPCC AR6 WG1 is not in fact neutral w/ respect to scenario assumptions because it has an overwhelming emphasis on unlikely (it’s word), implausible (our word) scenarios,” Pielke added.

According to the global warming cultists the East coast was supposed to be under water by now. These people are worse than the rapture people who claim the end times are here.

If these cuckoos get everything they want, precisely how soon will hurricanes not form, fires not start, and ice caps stop melting in all arctic and antarctic areas?  Inquiring minds want to know.
