Dispite constant bad news (May was the hottest on record in the contiguous USA and Edmonton), I remain hopeful:
Sucking carbon dioxide from air is cheaper than scientists thought
Estimated cost of geoengineering technology to fight climate change has plunged since a 2011 analysis.

The study, in Joule, was written by researchers at Carbon Engineering in Calgary, Canada, which has been operating a pilot CO2-extraction plant in British Columbia since 2015. That plant — based on a concept called direct air capture — provided the basis for the economic analysis, which includes cost estimates from commercial vendors of all of the major components. Depending on a variety of design options and economic assumptions, the cost of pulling a tonne of CO2 from the atmosphere ranges between US$94 and $232. The last comprehensive analysis of the technology, conducted by the American Physical Society in 2011, estimated that it would cost $600 per tonne.
