Ya think?
"Unless market constraints are put in place, growth in aviation emissions will result in the sector's emissions amounting to all or nearly all of the annual global CO
2 emissions budget by mid-century, if climate change is to be held to a temperature increase of 2 °C or less."

- ekianjo 7y agoGrowth is not something that continues forever. There's already constraints on the aviation industry (lack of pilots, congested routes) that will anyway slow down the growth significantly as time goes.
- ekianjo 7y agoThe same links says: "The central case estimate is that aviation's contribution could grow to five percent of the total contribution by 2050 if action is not taken to tackle these emissions, though the highest scenario is 15 percent." So which is it? 5%/15% or 100% by 2050?
- jupp0r 7y agoThe article you quote validates my point by assuming other emissions can be decreased to a minimum. If all emissions we have to worry about in 2050 was air travel, that would be spectacularly good news!
- easytiger 7y agoonce you get rid of other big thing, this now small thing becomes big, relatively speaking. Getting rid of air travel completely would give 0.03 degree tep benefit
- api 7y agoThat assumes vast reductions in emissions from every other sector except air travel, for physical energy density reasons. Air travel alone is not sufficient to affect climate much... if we were to get rid of fossil fuels on the ground.
- rsynnott 7y agoThat's in the scenario where fossil fuel use elsewhere is essentially eliminated; eliminating it for air travel is obviously particularly challenging.
