for example, we have a lower understanding of the effect of aerosols while we have a high understanding of the warming effect of carbon dioxide.

in 2000, hansen advanced an alternative view of global warming over the last 100 years, arguing that during that time frame the negative forcing via aerosols and the positive forcing via carbon dioxide (co 2) largely balanced each other out, and that the 0.74±0.18 °c net rise in average global temperatures could mostly be explained by greenhouse gases other than carbon dioxide, such as methane and chlorofluorocarbons.
