Comparing two spatio-temporal processes are often a desirable exercise. For example, assessments of the difference between various climate models may involve the comparisons of the synthetic climate random fields generated as simulations from each model. We develop rigorous methods to compare two spatio-temporal random processes both in terms of moments and in terms of temporal trend, using the...

The policy problem posed by climate change is daunting. Absent evidence that climate change is not a risk to human and natural systems, the world faces an unending series of difficult international negotiations about measures to limit greenhouse gas emissions. To be successful, the resulting climate regime must be able to survive over many decades, adapting to changing economic conditions, to e...

Unlike peer nations’ residents, Americans are less accepting of, and concerned by, (especially anthropogenic) climate change. Reinforced Theistic Manifest Destiny theory (RTMD; e.g., Ranney, 2012) explains many such “U.S.exceptionalist” phenomena by combining geopolitical history with six belief constructs: afterlife, deity, nationalism, creation, evolution, and global warming. We assess predic...

Climate change has become the preeminent sustainability issue, receiving significantly more political, corporate, media and public attention than other pressing environmental and social issues. Around the world, a diverse movement has emerged seeking stronger action to respond to climate change. However, this movement lacks cohesion and has failed to build sufficient political power to trigger ...

Natural unforced variability in global mean surface air temperature (GMST) can mask or exaggerate human-caused global warming, and thus a complete understanding of this variability is highly desirable. Significant progress has been made in elucidating the magnitude and physical origins of present-day unforced GMST variability, but it has remained unclear how such variability may change as the c...
