Sucking Away the Greenhouse Gases?

Experts have claimed that we only have a very limited time (less than 5 years?) to curb the effects of 'greenhouse gas' emissions to an extent that limits the average global temperature increase to the 1.5 degrees Centigrade rise agreed at the Paris summit (and this was very much a 'guesstimate'). After that, our fate could well be sealed by the effectiveness of as yet unproven technologies such as carbon capture (https://www.seeker.com/earth/climate/humanity-shouldnt-rely-on-negative-emissions-technology-to-curb-climate-change).
