Direct air capture is not currently viable strategy. Likely increases carbon pollution (more carbon energy required to than saved). See @mzjacobson.bsky.social's work: news.stanford.edu/stories/2019... & Joe Romm's review for our center (@penncssm.bsky.social): bpb-us-w2.wpmucdn.com/web.sas.upen...
Study casts doubt on carbon capture
Current approaches to carbon capture can increase air pollution and are not efficient at reducing carbon in the atmosphere, according to research from Mark Z. Jacobson.

You could also mention that the projected atmospheric CO₂ growth rate will be much lower in 2025 (2.6ppm, red dot on the figure).

You are confusing CO₂ emissions and CO₂ concentrations.

Keeping warming well below 2°C is still within reach, but with massive acceleration of emission mitigation.
It’s time to step up, not to give up.

The remaining carbon budget for 1.7°C or 2°C is 525 GtCO2 and 1055 GtCO2 respectively, equivalent to 12 and 25 years of current CO₂ emissions.

Time is up for 1.5°C. The remaining carbon budget for 1.5°C is virtually exhausted: 170 GtCO2, equivalent to 4 years at the 2025 emissions levels.

Last, we update the remaining carbon budget, that is the amount of CO₂ humanity can still emit in the future while limiting global warming to 1.5°C , 1.7°C or 2°C.

Since 1960, that climate impact leads to a loss of carbon from land and ocean (relative to what they would have been without climate change). We attribute that 8ppm (8%) of the observed atmospheric CO₂ increase of 100 ppm since 1960 is due to this weakening of the sinks.

We also analysed the effect of climate change on the sinks using our models separating the effect of increased atmospheric CO₂, from the effect of climate change.
Result: The land and ocean sinks would have been 25% and 7% larger in the absence of climate change.

and land sink to return to a stronger “neutral” state.
So the so called “collapse” of the land sink was a short term response to climate anomalies, not a long term response.
