> I don't think I've ever seen a study which has said that the amount of carbon produced by these local changes in biomes is anywhere near the carbon saved by the move to renewables.

I recommend you read the paper for a review of research evidence that this might be true for large-scale wind energy installations.

4.2.4. Increase in Biological CO2 Emissions Caused by Wind Farms

"Typically, the annual emissions from soil respiration are roughly balanced by the absorption of CO2 via photosynthesis ... However, the total emissions from soil respiration are known to increase with temperature. Estimates of the exact rates of increase vary between studies, and there are many complexities in extrapolating from the results of e.g., a mid-latitude forest or a tropical region to global estimates ... Nonetheless, most studies suggest that the warming of soils generally leads to an increase in biological CO2 emissions from soil respiration. Therefore, given that the global CO2 emissions from soil respiration are an order of magnitude greater than anthropogenic emissions, we suggest that the increase in biological CO2 emissions caused by wind farms warming the night-time soil temperatures could potentially be similar in magnitude to the reduction in anthropogenic CO2 emissions from the wind farms."
