Climate evidence finds us guilty as charged

The article presents a study on the extent and pattern of the rise in ocean temperatures. The oceans eventually absorb 84 percent of the Earth's extra heat and the distribution of that heat closely matches what climate models predict would be the effect of human activity. The human component included both the warming effect of greenhouse gases and the shading effect of the aerosols in urban smog and forest fires, which prevent radiation from reaching the Earth's surface. The upper layer is almost certainly a result of the thick brown haze of pollutants over southern Asia, which has largely cancelled out atmospheric warming in the region.
