Bees represent vital natural assets contributing significantly to global food production and the maintenance of ecosystems. While studies on climate change effects impacting major pollinators like honeybees bumblebees raise concerns about diversity crop productivity, comprehensive global-scale analyses remain limited. This study explores repercussions warming 1365 bees across seven families worldwide. To compile a robust bee occurrence dataset, we utilized innovative ‘BeeBDC’ R package that amalgamated over 18.3 million records sourced from various repositories. Through species distribution models under SSP585 scenario in year 2070, assessed how influences suitability scale, examining impacts continents. Our findings suggested approximately 65% are likely witness decrease their distribution, with reductions averaging between 28% Australia 56% Europe. Moreover, our analysis indicated change’s impact is projected be more severe Africa Europe, while North America expected higher number (336) expanding distribution.
