It is true actually! In the Global Carbon Budget we do not usually show the LUC like this, because of interannual variability & uncertainty. But it is what the data says!

4. If you're at a funeral "I'm sorry for your loss" is a perfectly fine thing to say. The family aren't marking people on originality.

So lets take stronger action to cut SLCPs; lets just not do it in a framework that allows more CO2 emissions. Because ultimately its CO2 that is driving long-term warming of the climate system. SLCP's alone cannot credibly neutralize CO2 emissions; they need to be coupled with future carbon removal.
