“Temperature Trends in the Lower Atmosphere: Steps for Understanding and Reconciling Differences,” tackles difficulties that have impeded understanding of changes in atmospheric temperatures and the causes of these.

According to the report, there is no discrepancy in the rate of global average temperature increase for the surface compared with levels in the atmosphere. This discrepancy had previously been used to challenge the validity of the causes of observed climate change. This is an important update of the conclusions of earlier reports from the U.S. National Research Council and the Intergovernmental Panel on Climate Change. From...
