I haven't read the paper, but forests also have a cooling effect due to transpiration (and can benefit regional rainfall if the forest is large enough). Also, the soil is much cooler under a forest than when the forest is cut; not sure what this does beyond a regional level (i.e. maybe this effect is lost at a global scale?). Biodiversity losses from natural forests (as opposed to tree plantations) are another thing to consider, whether they 'count' as ecosystem service losses or some other valuation--e.g., without trees, soil erosion and even landslides can occur (depending on topography and other factors) and result in various short and long term costs.
