I have a new paper, led by Jess Raff,
that analyzes sediment transport and sediment budgets
in the Ganges-Brahmaputra-Meghna delta, and assesses the implications of
sediment flow for sustainability in the face of sea-level rise and the
diversion and damming of major rivers.
I am very excited to announce that I have been selected for a Fulbright Scholar
Award, which will allow me to spend a large part of the next academic year at
the University of Calgary’s
Werklund School of Education
as the Fulbright Canada Research Chair in Digital Technologies and
Sustainability.
A short film about my collaborative interdisciplinary research project in Bangladesh is featured at the AGU Cinema at the 2019 Fall Meeting of the American Geophysical Union, and is also available on YouTube. The film, by Andre Leroux, focuses on interdisciplinary research on the changing river systems of Bangladesh and the prospect of sustainably managing the delta in the face of climate change and sea-level rise.
I have a new paper in the journal
Energy Efficiency, co-authored with Alex Maki, Emmett McKinney,
Mike Vandenbergh, and Mark Cohen,
about employers who offer employee benefits to promote energy efficiency.
Cities face challenges on many fronts as they work to assure their residents of safe and reliable access to water.
Changes in both supply and demand are driven by complex interactions among many human and natural factors, such as
drought, infrastructure, population growth, and land-use. Climate change adds new complexities and uncertainties as
cities plan for the future. In the past, challenges to water security were addressed by
Promethean energy- and technology-intensive infrastructure projects,
such as long-distance transfers, desalination, and artificial aquifer recharge;
but in recent years, attention to soft approaches has grown.
Soft approaches
to water security focus on improving efficiency in obtaining and consuming water, and as John Fleck
documented in his book,
Water Is for Fighting Over,
a number of cities have made impressive progress toward resilience and sustaniability.
Comparisons of observed trends of energy and carbon intensity in the global
economy to trends implied by emissions scenarios used in policy analysis
suggested that those scenarios were severely over-optimistic about the rate at
which the world would spontaneously decarbonize its economy.
I update these analysis, using global emissions since 2005, and find
that observed rates of decarbonization are not far behind those implied by
the RCP 4.5 policy scenario. This suggests that the policy challenge may not
be as difficult as previous work has reported.
It is important to keep outright falsehoods out of journalism and the scientific literature. Creationism and fear-mongering about vaccine safety do not deserve equal time with biological and medical science. But in matters of regulatory science, where there is not a clear consensus on methods and where it is impossible to strictly separate factual judgments from political ones, the literature on science in policy offers strong support for keeping discourse open and free, even though it may become heated. But it also calls on individual scientists to consider how the results of their research and their public statements about it are likely to be used.
With President Trump’s announcement to pull the United States out of the Paris Agreement, many other countries around the world—and cities and states within the U.S.—are stepping up their commitments to address climate change.
But one thing is clear: Even if all the remaining participating nations do their part, governments alone can’t substantially reduce the risk of catastrophic climate change.
