If you see your scepticism as common sense, then say why. What is frustrating is to see sceptics like yourself paint their position as sensible, yet offer previously debunked reasons or no reasons as justification. This now seems to be the case with biosequestration, with Robert Merkel raising a couple of phoney arguments, which I will respond to.
"the fact is that natural gas fields have been storing CO2 for millions of years"
This is a bit like finding an intact ancient Greek olive jar on the seabed and concluding that ancient Greek olive jars last for thousands of years. The fact is that most natural gas escapes, and a gas field is the exception.
"There's evidence, for instance, that using biochar in forested areas can increase soil microbial activity. Guess what, that releases much of the CO2 back again."
Research has been done to compare the carbon loss from degraded agricultural soils with and without the addition of charcoal, and using natural forest as a control. The researchers found that while the agricultural land released more carbon than the forest, the charcoal treated soil released 2.75 t/ha/yr less carbon than the untreated soil.
