[Episode #112] – Climate Science Part 11 – Climate Confusion
What do the various emissions scenarios published by the IPCC really mean? Is the worst-case RCP8.5 scenario “bollox,” as some have asserted, or it useful? Are we already doomed to experience seven feet of sea level rise and five degrees Celsius of warming globally, or is there still a chance that we can limit warming to two degrees? And if so…how likely is it that we can hit that target? How much can our energy transition efforts, both now and in the foreseeable future, do to mitigate that warming? Should our scenarios err on the side of being too extreme to account for unknown feedback effects and tipping points that may come in the future, or should we try to be as accurate as possible with our modeling, given the available data and scientific tools?
In this 11th part of our miniseries on climate science, we attempt to answer these questions and help our listeners sort out the various perspectives, from the tame to the apocalyptic, that feature in the current debates about our climate future. We hope that it will leave you with a much better understanding of what the climate scenarios really mean, how likely they are, and what the actual trajectory of climate change might be. We’re not out of the woods by any means, but our prospects may be better than you think!
