In response to claims made by Bob Carter that the Intergovernmental Panel on Climate Change had not uncovered evidence that global warming was caused by human activity, a former CSIRO climate scientist stated that Bob Carter was not a credible source on climate change and that «if he [Carter] has any evidence that [global warming over the past 100 years] is a natural variability he should publish through the peer review process.»

These activities can be grouped under the following areas: improve our knowledge of Earth's past and present climate variability and change; improve our understanding of natural and human forces of climate change; improve our capability to model and predict future conditions and impacts; assess the Nation's vulnerability to current and anticipated impacts of climate change; and improve the Nation's ability to respond to climate change by providing climate information and decision support tools that are useful to policy makers and the general public.»
