Sunset on Net Zero: A Heretic's Guide to the Futile CO2 Target
SUNSET ON NET ZERO describes in detail why Net Zero CO2 is pointless and unachievable. It explains in understandable terms the up-to- date thoughts of the greatest minds of today in physics, meteorology, economics, engineering, and the geosciences.
Net Zero CO2 is pointless because we have now confirmed by satellites that 90% of CO2 warming has already happened. CO2 is not an existential threat but clouds, El-Niño, and human habitation are significant drivers of global warming that are often ignored.
Net Zero CO2 is unachievable because the green technology alternatives are unreliable and unaffordable. Wind and solar power triple electricity costs, building fully electric vehicles produces at least one-half of CO2 emissions they are meant to avoid, and heat pumps will leave you dangerously cold in the winter. Green hydrogen, air capture CO2, and carbon capture and storage are prescriptions for national bankruptcy. The supply of key metals and minerals required to achieve Net Zero need to be at least doubled—some much more—and are often controlled by a very few. Net Zero comes with huge environmental and agricultural costs.
We have been through similar climatic temperature changes before, more recently than you think. Our efforts to control it are futile.

About the author
Ronald Paul Barmby
2 books10 followersRon Barmby is a Professional Engineer with a Master’s degree. His four-decade career in energy geoscience took him to over 40 countries on five continents, and included the key technical disciplines also used in climate science and net zero CO2 technology. His previous book, Sunlight on Climate Change: A Heretic’s Guide to Global Climate Hysteria resulted in advanced level scientific experts sharing their research, enabling Ron author Sunset on Net Zero: A Heretic’s Guide to the Futile CO2 Target. A twelfth-generation Canadian, Ron and his wife, Lysle, now divide their time between Celista, British Columbia and Calgary, Alberta.

An excellent follow-up to Ron Barmby’s first book, Sunlight on Climate Change: A Heretic's Guide to Global Climate Hysteria, which brilliantly addressed two central questions: (1) Do humans cause climate change? and (2) Is climate change catastrophic? In this outstanding sequel, Sunset on Net Zero, A Heretic’s Guide To The Futile CO₂ Target, Barmby advances the discussion to consider a new question: “Can we reduce human-emitted CO₂ to net zero by 2050?”
Drawing on insights from members of the CO₂ Coalition and his association with the Clintel Foundation, Barmby masterfully guides readers through a clear, evidence-based exploration of climate science. His underlying theme is that science itself does not lie, however, people can certainly misrepresent it, whether through agenda-driven motives, or simply a lack of rigor... readers must ultimately judge for themselves.
This author doesn’t pull any punches as he drives a stake into the heart of global misinformation as its had profound political and economic consequences. Much like Galileo unveiling his heliocentric model in a fiercely politicized climate, Barmby refuses to shy away from challenging those who distort the truth. This book is a must read for Canadian policy makers. Glen Thorne
