Hurricanes are worse, but experience, gender and politics determine if you believe it

Objective measurements of storm intensity show that North Atlantic hurricanes have grown more destructive in recent decades. But coastal residents’ views on the matter depend less on scientific fact and more on their gender, belief in climate change and recent experience with hurricanes, according to a new study by researchers at Princeton University, Auburn University-Montgomery, the Louisiana State University and Texas A&M University.

A global reanalysis of storm surges and extreme sea levels

Extreme sea levels, caused by storm surges and high tides, can have devastating societal impacts. To effectively protect our coasts, global information on coastal flooding is needed. Here we present the first global reanalysis of storm surges and extreme sea levels (GTSR data set) based on hydrodynamic modelling. GTSR covers the entire world’s coastline and consists of time series of tides and surges, and estimates of extreme sea levels. Validation shows that there is good agreement between modelled and observed sea levels, and that the performance of GTSR is similar to that of many regional hydrodynamic models. Due to the limited resolution of the meteorological forcing, extremes are slightly underestimated. This particularly affects tropical cyclones, which requires further research. We foresee applications in assessing flood risk and impacts of climate change. As a first application of GTSR, we estimate that 1.3% of the global population is exposed to a 1 in 100-year flood.

Lessons from PPP2000: Living with Earth's Extremes-Report from the PPP2000 Working Group to the Office of Science and Technology Policy Subcommittee on Natural Disaster Reduction

This book is a series of reports summarizing discussions and recommendations from a series of forums about strategies to deal with natural disaster. The focus is on changing human behavior and development in order to coexist with natural phenomena rather than trying to control natural phenomena. Read More

The Interplay between Climate Change, Forests, and Disturbances

Library Holdings. Climate change affects forests both directly and indirectly through disturbances. Disturbances are a natural and integral part of forest ecosystems, and climate change can alter these natural interactions. When disturbances exceed their natural range of variation, the change in forest structure and function may be extreme. Each disturbance affects forests differently. Some disturbances have tight interactions with the species and forest communities which can be disrupted by climate change. Impacts of disturbances and thus of climate change are seen over a broad spectrum of spatial and temporal scales. Future observations, research, and tool development are needed to further understand the interactions between climate change and forest disturbances. Read More


In this USGRP Seminar, speakers try to answers questions like:What is the current status of hurricane track prediction? What caused the record number of Atlantic tropical storms in 1995? Are we witnessing a change in the number and frequency of tropical storms? Do these storms represent a changing climate? What will tropical storms be like in a greenhouse warmer world? Read More


EERL's mission is to be the best possible online collection of environmental and energy sustainability resources for community college educators and for their students. The resources are also available for practitioners and the public.
