Species distribution changes associated with human-mediated climate change have important consequences on ecosyst ems and human well-being. Despite mounting evidence\, our knowledge of the redistribution of life on Earth is still incomplete with only 0.6% of the described biodiversity on Earth for which range shifts have been document ed. I will present the BioShifts database which contains 30\,534 observations of velocity of range shifts (VRS) for 12\,415 taxa\, coverin g 56 taxonomic classes and 20 phyla across both terrestrial and marine sys tems. This database is clearly biased towards more VRS data for mobile ect otherms\, iconic endotherms and seed-bearing plants. Similarly\, a strong geographical bias is noticeable towards the most developed regions in the World. Contrary to former meta-analyses and quantitative syntheses on clim ate-induced species range shifts\, I will show the extreme variability in the magnitude and direction of VRS values that is hiding behind averages a cross broad taxonomic groups (e.g.\, amphibians\, arthropods\, birds\, ins ects\, mammals\, molluscs and plants) or position within the geographic ra nge (i.e.\, trailing edge\, centroid of the range and leading edge). I wil l also show that VRS values do not necessarily conform to the observed val ues in the magnitude and direction of velocity of isotherm shifts (VIS)\, suggesting other determinants behind the great redistribution of life on E arth.
