North American communities that are on the front lines of managing excess stormwater flows need strong engagement from governments and civil society to develop and implement sustainable solutions to this widespread problem. “The steps we take now will help future generations. One of the first steps policy makers should take is to properly assess how vulnerable our communities are to the damaging effects of excess stormwater,” stated Gustavo Alanís-Ortega.

“The Value of Green Infrastructure for Urban Climate Adaptation is intended as a resource for planners and decision makers at all levels of government. The innovative examples we review indicate that green infrastructure investments can provide a cost-effective way to enhance community resilience and prosperity,” said Steve Winkelman.

“While the costs of adapting to climate change will be in the billions of dollars, New York City’s working philosophy is that the costs of not adapting will be far greater,” writes Bruce Stutz.

“The report brings together messages on water and climate change from the “World Water Development Report 3: Water in a Changing World”. Carbon is a measure of the anthropogenic causes of climate change; water is a measure of its impacts,” writes Olcay Ünver.

Evidence of the impact of climate change on the earth’s hydrological cycle is mounting in many regions of the world, in the form of increased frequency of floods, droughts and other water hazards and changes in long-term trends in precipitation.

“The debate about Climate Change has generated a policy war between proponents of “hard caps” versus those who favour “intensity unit” approaches to regulating discharges of greenhouse gases. The author argues that intensity units are an effective tool for measuring performance in reducing pollution and ensuring that the public interest is protected,” wrote Peter Krahn.
