Public policy-makers and academic scientists both want solid science on climate change, but the medium for that science must suit each group's needs.

This series of interactive maps is truly one of a kind. Most sea level rise visualizations are based on increments of sea level rise and will let you see, for example, how the coast will look with 1 foot of rise, 2 feet of rise, etc. These maps let you visualize what the coast will look like in a given year in the future, which communities will be most affected, and how cutting our greenhouse gas emissions could help to avoid chronic flooding for hundreds of US communities.

This peer-reviewed paper accompanied the Union of Concerned Scientists' When Rising Seas Hit Home report (see below). While the data underlying this article and the UCS report are the same, this article is geared toward technical audiences while the report is geared toward non-scientific audiences.

This national analysis identifies when US coastal communities will face a level of disruptive flooding that affects people's homes, daily routines, and livelihoods. It identifies hundreds of communities that will face chronic inundation and possible retreat over the coming decades as sea levels rise.

Sea level rise is poised to bring more frequent, more extensive coastal flooding to communities up and down the East and Gulf Coasts of the United States. This peer-reviewed publication quantifies those changes. The data show that, within the next 30 years, many coastal communities could witness hundreds of minor floods each year.

The US military has 128 coastal installations. Dahl Scientific, in partnership with the Union of Concerned Scientists, evaluated the the growing exposure of military installations to both routine and catastrophic flooding. This project resulted in more than a dozen site-specific fact sheets and hundreds of exposure maps.

Sea level rise allows storm surge to reach farther inland increase the depth of flooding in affected coastal areas. In this report, Dahl Scientific partnered with the Union of Concerned Scientists to analyze the current and future impact of storm surge on critical electric power infrastructure.

Fossil fuel-based energy has long been a primary contributor to climate change since the Industrial Revolution, but it, like all people and industries, will also be on the receiving end of climate change. Oil companies face a future in which sea level rise will expose their infrastructure to more extensive, more severe storm surge. This Union of Concerned Scientists report, for which Dahl Scientific provided storm surge analyses, evaluates the physical exposure of US oil refineries to storm surge as well as the degree to which major oil producers have (or have not) disclosed that risk to shareholders.

Nuisance level flooding in US coastal communities has quadrupled (or more) in frequency since the 1970s. This UCS report shows that as sea level continues to rise over the next 30 years, that flooding will become both more frequent and more extensive. Many communities are projected to experience nearly 200 flood events per year by mid-century. Dahl Scientific performed the analyses underlying this report.
This work was later expanded and published by K. Dahl in PLOS-ONE.

At times in Earth's history, pulses of meltwater from glaciers and ice sheets are thought to have caused changes in ocean circulation as well as surface climate. In this study, we used a global climate model to simulate one of these pulses to the North Atlantic and found significant shifts in climate patterns far afield in the tropics. Such studies give us insight into the climatic implications of ice loss in the past and, potentially, in the future.
