Is the warming a consequence of human activities?
In 1995, the IPCC concluded that the balance of evidence suggested that the recent observed warming of the Earths atmosphere was due to human activities. In 2001 (and again in 2007), it concluded that “most of the warming observed over the last 50 years is likely to be attributable to human activities.” Recent temperature rises can only be explained by human activities computer models that simulate climate demonstrate that it other variations, such as the suns output and changes in volcanoes cannot account for all the warming. Only when human activities are included in the models do they correlate with observed changes. Back to TOP Can we prevent climate change by reducing emissions of greenhouse gases? Experiments run on global climate models show us that when we reduce emissions of carbon dioxide, we reduce the rate of rise of average global temperatures and so lessen the rate and impacts of climate change. We can therefore slow the rate of warming by changing our behaviour. However,
