Projected climate impacts on pollinators show mixed responses across Europe but are greater under 3ºC GWL  . Increasing homogenisation of populations may increase vulnerability to extreme events . Geographical changes to the climatic niche of pollinators are similar to those of insects, with mixed trends, depending on group and location . In NEU, species richness may increase for some groups , with unclear trends for bumblebees . Future land use will have important effects on pollinator distribution  as habitat fragmentation in densely populated Europe decreases opportunities for range shifts and microclimatic buffering .
