Past meta-analyses of the response of marine organisms to climate change have examined a limited range of locations1, 2, taxonomic groups2, 3, 4 and/or biological responses5, 6. This has precluded a robust overview of the effect of climate change in the global ocean. Here, we synthesized all available studies of the consistency of marine ecological observations with expectations under climate change. This yielded a meta-database of 1,735 marine biological responses for which either regional or global climate change was considered as a driver. Included were instances of marine taxa responding as expected, in a manner inconsistent with expectations, and taxa demonstrating no response. From this database, 81–83% of all observations for distribution, phenology, community composition, abundance, demography and calcification across taxa and ocean basins were consistent with the expected impacts of climate change. Of the species responding to climate change, rates of distribution shifts were, on average, consistent with those required to track ocean surface temperature changes. Conversely, we did not find a relationship between regional shifts in spring phenology and the seasonality of temperature. Rates of observed shifts in species’ distributions and phenology are comparable to, or greater, than those for terrestrial systems.

Figures

  1. Global distribution and regional location of marine ecological climate-impact studies.
    Figure 1: Global distribution and regional location of marine ecological climate-impact studies.

    a, Observed responses (n=1,735) of marine organisms to climate change from 208 single- and multispecies studies showing responses that are consistent with climate change (blue, n=1,092), opposite to those expected (red, n=225) or are equivocal (yellow, n=418). Each circle represents the centre of a study area. Where points fall on land, it is because they are centroids of distribution that surround an island or peninsula. Pie charts show the proportions within regions bounded by red squares and in the Mediterranean Sea; numbers indicate the total (consistent, opposite plus equivocal) observations within each region. b, Frequency of observations and ocean area by 5° latitudinal bins; red dotted line shows the proportion of ocean area within each latitudinal bin. cf, Observations from the Southwest Pacific (c), Northeast Atlantic, North Sea and Mediterranean Sea (d), California Current (e) and Northwest Atlantic (f).

  2. Global response rates to climate change by taxon.
    Figure 2: Global response rates to climate change by taxon.

    a,b, Rates of change (means±s.e.m.) of marine taxonomic or functional groups in distribution at the leading edges (red circles), trailing edges (brown triangles) and from all data regardless of range location (black squares) (a), with axis scale on square-root for display, so standard errors are asymmetric, and phenology during spring (red circles) and summer (brown triangles) (b). Negative phenological changes (generally earlier) and positive distribution changes (generally poleward into previously cooler waters) are consistent with warming. Sample sizes (n) are given above each taxon or functional group (a, leading edges upper row, trailing edge lower row; b, spring upper row).

  3. Marine biological responses as a function of the velocity of climate change and seasonal climate shift.
    Figure 3: Marine biological responses as a function of the velocity of climate change and seasonal climate shift.

    a, Magnitude of observed shifts in species distributions for marine taxonomic or functional groups against expected magnitude. Two hundred and seventy-nine observed shifts taken from 36 published studies (null responses excluded). b, Observed shifts in spring phenology (daysdec−1) for marine taxonomic or functional groups against expected shift in spring phenology taken as shift in seasonal sea surface temperatures. Fifty-one observed shifts taken from 17 published studies. Expected distributional and phenology shifts over 1960–2009 calculated using the Hadley Centre data set (HadlSST 1.1) and methods presented in ref. 8. April temperatures used for Northern Hemisphere spring phenology and October temperatures for Southern Hemisphere phenology.

  4. Proportion of marine observations consistent with climate change predictions using observations from both single- and multispecies studies (all,
n[thinsp]=[thinsp]1,323) and multispecies studies alone (n[thinsp]=[thinsp]1,151).
    Figure 4: Proportion of marine observations consistent with climate change predictions using observations from both single- and multispecies studies (all, n=1,323) and multispecies studies alone (n=1,151).

    ac, Mean and standard error of responses by taxonomic or functional group (a), latitudinal zone (b) and response type (c) show significantly higher consistency than expected from random as determined by binomial tests for each estimate against 0.5 (dashed line at 50% consistency). The vertical solid lines are the means across all observations. Significance of results is listed next to labels (***, p<0.001; **, p<0.01; *, p<0.05). Sample sizes are listed to the right of each row.
