' Circles in Europe represent 1 to 7,500 data series.
Figure SM-1.3. Observed changes in physical systems (cryosphere, hydrology and coastal processes) and biological systems (marine and freshwater biological systems, terrestrial biological systems) for studies ending in 1990 or later with at least 20 years of data used in chapter sysnthesis assessment in Section 1.4. Dots represent about 75 studies, which have >29,000 data series (of which ~27,800 are from European phenological studies of flora and fauna). Observed trends in surface air temperature and sea-surface temperature 1970-2004 (HadCRUT3 Brohan et al., 2006). White regions do not contain sufficient observational climate data to estimate a trend.
