This is big news.
Shell has just, for the first time, published a 1.5C scenario.
"Sky 1.5 is a highly ambitious pathway that is still technically possible but extremely challenging."

It's worth re-reading @DrSimEvans article for @CarbonBrief from 2018 when he *cough* drilled into Shell's then-new "well below 2C" Sky scenario https://www.carbonbrief.org/in-depth-is-shells-new-climate-scenario-as-radical-as-it-says
If you want to go back further to see Shell's "journey", read Simon's 2015 interview with Jeremy Bentham, who oversees Shell's scenarios...
Asked why Shell wouldn't then publish a 2C compatible scenario:
"I’m not sure how helpful it would be." https://www.carbonbrief.org/the-carbon-brief-interview-jeremy-bentham

Here's what the world's energy consumption profile looks like under Shell's new 1.5C scenario out to 2100.
Note how the whole world's energy consumption goes carbon negative around 2055?!

By relying so heavily on negative emissions sucking CO2 out of the atmosphere in the second half of this century, this is what Shell's 1.5C scenario would mean for global temps...
Temps overshoot 1.5C and only *just* return to that level by 2100
