- Carbon dioxide lifetime 50-100x longer than generally reported
- Improvements in CO2 monitoring
- British plan for “floodable” towns
- New technology enables electricity from slower water currents
- First “solar rooftop” completed, others in jeopardy
- Distributed book publication and printing, anyone?
There is a great deal of confusion regarding how long carbon dioxide (CO2) persists in the atmosphere. There are at least two reasons for this. The first reason is that there are multiple physical and biological processes that combine to remove CO2 from the air and they behave differently and at different speeds. The second reason is that the Intergovernmental Panel on Climate Change (IPCC) has changed how it describes the lifetime of CO2 in the Summary for Policymakers twice over the course of four assessment reports. And since most politicians and media don’t dive deeper into the assessment reports than the summaries, some confusion is reasonable, if unfortunate.
A new paper titled Atmospheric Lifetime of Fossil-Fuel Carbon Dioxide and reported on by Nature Reports aims to describe and understand the confusion over the lifetime of CO2. Continue reading
