Scientists questioning the accuracy of IPCC climate projections

These scientists have said that it is not possible to project global climate accurately enough to justify the ranges projected for temperature and sea-level rise over the 21st century. They may not conclude specifically that the current IPCC projections are either too high or too low, but that the projections are likely to be inaccurate due to inadequacies of current global climate modeling.

Scientists arguing that global warming is primarily caused by natural processes

Graph showing the ability with which a global climate model is able to reconstruct the historical temperature record, and the degree to which those temperature changes can be decomposed into various forcing factors. It shows the effects of five forcing factors: greenhouse gases, man-made sulfate emissions, solar variability, ozone changes, and volcanic emissions.[71]

These scientists have said that the observed warming is more likely to be attributable to natural causes than to human activities. Their views on climate change are usually described in more detail in their biographical articles.
