  - Tree planting is a prevalent strategy to mitigate urban heat. Tree cooling efficiency(TCE),
    defined as the temperature reduction for a 1% tree cover increase, plays animportant
    role in urban climate as it regulates the capacity of trees to alter the sur-face
    energy and water budget. However, the spatial variation and more importantly,temporal
    heterogeneity of TCE in global cities are not fully explored. Here, we usedLandsat-based
    tree cover and land surface temperature (LST) to compare TCEs at areference air
    temperature and tree cover level across 806 global cities and to exploretheir
    potential drivers with a boosted regression tree (BRT) machine learning model.From
    the results, we found that TCE is spatially regulated by not only leaf area index(LAI)
    but climate variables and anthropogenic factors especially city albedo, withouta
    specific variable dominating the others. However, such spatial difference is attenu-ated
    by the decrease of TCE with tree cover, most pronounced in midlatitude cities.During
    the period 2000–2015, more than 90% of analyzed cities showed an increas-ing trend
    in TCE, which is likely explained by a combined result of the increase in LAI,intensified
    solar radiation due to decreased aerosol content, increase in urban vaporpressure
    deficit (VPD) and decrease of city albedo. Concurrently, significant urbanafforestation
    occurred across many cities showing a global city-scale mean tree coverincrease
    of 5.3 ± 3.8% from 2000 to 2015. Over the growing season, such increasescombined
    with an increasing TCE were estimated to on average yield a midday sur-face cooling
    of 1.5 ± 1.3°C in tree-covered urban areas. These results are offeringnew insights
    into the use of urban afforestation as an adaptation to global warmingand urban
    planners may leverage them to provide more cooling benefits if trees areprimarily
    planted for this purpose.@eng
