Abstract Using data series on atmospheric carbon dioxide and global temperatures we investigate the phase relation (leads/lags) between these for the period January 1980 to December 2011. Ice cores show atmospheric CO2 variations to lag behind atmospheric temperature changes on a century to millennium scale, but modern temperature is expected to lag changes in atmospheric CO2, as the atmospheric temperature increase since about 1975 generally is assumed to be caused by the modern increase in CO2. In our analysis we use eight well-known datasets; 1) globally averaged well-mixed marine boundary layer CO2 data, 2) HadCRUT3 surface air temperature data, 3) GISS surface air temperature data, 4) NCDC surface air temperature data, 5) HadSST2 sea surface data, 6) UAH lower troposphere temperature data series, 7) CDIAC data on release of anthropogene CO2, and 8) GWP data on volcanic eruptions. Annual cycles are present in all datasets except 7) and 8), and to remove the influence of these we analyze 12-month averaged data. We find a high degree of co-variation between all data series except 7) and 8), but with changes in CO2 always lagging changes in temperature. The maximum positive correlation between CO2 and temperature is found for CO2 lagging 11–12 months in relation to global sea surface temperature, 9.5-10 months to global surface air temperature, and about 9 months to global lower troposphere temperature. The correlation between changes in ocean temperatures and atmospheric CO2 is high, but do not explain all observed changes.

Solaktiviteten er på en nedadgående trend, og en britisk forsker mener det er 25 prosent sjanse for at sola blir like svak som under "den lille istid" for 400 år siden. Forskerne er uenige om konsekvensene.

Data fra iskjerner har tidligere demonstrert at atmosfæriske endringer i CO2 har etterfulgt temperaturendringer de siste hundretusener av år. Nå har vi funnet bevis for at dette også gjelder i moderne tid, forteller Ole Humlum, professor ved Institutt for geofag ved Universitetet i Oslo og professor II ved Universitetet på Svalbard. Artikkelen, som snart publiseres i tidsskriftet Global and Planetary Change, peker i retning av at det er temperaturendringene på Jorda som har styrt økningen i konsentrasjonen av karbondioksid i atmosfæren de siste tiårene. Forskerne bak artikkelen er, foruten Ole Humlum, Kjell Stordahl, statistiker ved Telenor og Jan-Erik Solheim, professor emeritus ved Institutt for fysikk og teknologi ved Universitetet i Tromsø
