Northern Hemisphere series is also expressed in standard deviations rather than temperature anomalies. # March 2009, v 1.0.0 # # Year Anomaly 2000 1.66 1999 1.24 1998 2.45 1997 0.45 1996 1.44 1995 1.79 1994 2.82 1993 1.61 1992 1.22 1991 0.82 1990 1.60 1989 1.41 1988 0.85 1987 0.36 1986 1.32 1985 2.23 1984 1.02 1983 1.03 1982 0.57 1981 0.01 1980 1.45 1979 1.97 1978 0.95 1977 0.98 1976 -0.03 1975 -0.07 1974 -0.01 1973 0.04 1972 -0.18 1971 0.82 1970 -0.39 1969 0.93 1968 0.25 1967 0.77 1966 0.08 1965 -0.73 1964 -0.03 1963 0.45 1962 0.32 1961 1.06 1960 0.92 1959 0.97 1958 1.48 1957 1.32 1956 1.28 1955 1.54 1954 1.46 1953 1.64 1952 0.65 1951 1.08 1950 1.94 1949 0.13 1948 1.70 1947 1.01 1946 1.92 1945 1.53 1944 1.38 1943 1.31 1942 1.20 1941 0.85 1940 0.17 1939 1.38 1938 0.17 1937 1.04 1936 1.54 1935 0.86 1934 1.22 1933 0.31 1932 0.52 1931 0.98 1930 1.73 1929 0.14 1928 0.62 1927 0.38 1926 0.15 1925 0.09 1924 0.38 1923 0.92 1922 0.05 1921 0.79 1920 0.44 1919 -0.11 1918 0.36 1917 -0.84 1916 -0.47 1915 -0.32 1914 -0.44 1913 -1.37 1912 -1.65 1911 -0.82 1910 -0.61 1909 -0.33 1908 -0.21 1907 -1.06 1906 -0.65 1905 -0.34 1904 -0.69 1903 -0.36 1902 -0.60 1901 -0.22 1900 -0.67 1899 -0.85 1898 0.27 1897 0.75 1896 0.67 1895 -0.03 1894 0.45 1893 -0.43 1892 -0.25 1891 0.20 1890 0.17 1889 0.28 1888 0.06 1887 -0.83 1886 0.29 1885 -0.75 1884 -0.56 1883 -0.45 1882 -0.29 1881 -0.20 1880 -0.20 1879 0.31 1878 0.78 1877 0.05 1876 0.32 1875 0.21 1874 0.11 1873 -0.22 1872 -0.68 1871 -0.58 1870 -1.16 1869 -1.58 1868 -0.89 1867 -1.25 1866 -1.30 1865 -0.70 1864 -1.14 1863 -0.12 1862 -0.24 1861 -0.28 1860 0.19 1859 -0.12 1858 -0.31 1857 -0.86 1856 -0.89 1855 -0.56 1854 -1.39 1853 -0.80 1852 -0.36 1851 -1.13 1850 -1.35 1849 -1.19 1848 0.13 1847 -1.08 1846 -0.41 1845 -1.26 1844 -1.27 1843 -1.58 1842 -0.76 1841 -1.27 1840 -1.33 1839 -1.82 1838 -1.65 1837 -2.42 1836 -1.09 1835 -1.84 1834 -0.30 1833 -1.49 1832 -1.39 1831 -1.18 1830 -0.39 1829 -0.07 1828 -0.43 1827 -0.26 1826 -0.60 1825 -1.46 1824 -0.70 1823 -0.66 1822 -1.00 1821 -1.82 1820 -2.20 1819 -3.08 1818 -2.57 1817 -2.90 1816 -2.26 1815 -2.46 1814 -2.03 1813 -2.13 1812 -2.23 1811 -0.19 1810 -0.93 1809 -0.02 1808 1.12 1807 0.24 1806 0.11 1805 0.27 1804 0.95 1803 -0.61 1802 -0.51 1801 -0.33 1800 -0.31 1799 0.20 1798 1.00 1797 0.43 1796 0.55 1795 0.09 1794 0.48 1793 0.13 1792 0.29 1791 -0.07 1790 -0.22 1789 -0.04 1788 -0.27 1787 0.99 1786 0.15 1785 0.43 1784 -0.32 1783 -0.49 1782 0.49 1781 0.38 1780 0.16 1779 0.70 1778 0.58 1777 0.93 1776 0.31 1775 0.60 1774 0.53 1773 -0.05 1772 -0.22 1771 -0.10 1770 0.04 1769 -0.46 1768 -0.66 1767 -0.15 1766 0.04 1765 -0.53 1764 -0.16 1763 0.40 1762 -0.34 1761 0.49 1760 0.56 1759 0.27 1758 0.29 1757 0.18 1756 0.79 1755 -0.38 1754 0.45 1753 0.31 1752 0.04 1751 -0.69 1750 -0.12
