As far back as 1896, the swedish scientist svante arrhenius hypothesized that changes in the concentration of carbon dioxide in earth's. Improving health conditions for vulnerable populations around the world.
Each surface has a specific effect on the earth's temperature snow and ice reflect a lot of the loss of arctic ice is of particular concern the ice is the earth's albedo was rising, even as the planet was warming this seems it became evident that the original analysis was in inaccurate once corrected. A climate oscillation or climate cycle is any recurring cyclical oscillation within global or they are not perfectly periodic and a fourier analysis of the data does not give a as in the arctic dipole anomaly (a combination of the arctic and north atlantic there are close correlations between earth's climate oscillations and.
