There is no conceivable way to get around the fact that we eventually will have to retreat. There are several ways to retreat, including buying out homes in low-lying, flood-prone areas and returning those areas to a more natural state; demolishing or moving buildings; and not rebuilding storm-damaged buildings. Simply fleeing from the beach by moving buildings one by one away from immediate danger won’t be enough. Planning should include keeping a community as intact as possible. Individual responses won’t maintain the recreational value of the beach and the all-important tourist industry.
A new air capture technology, developed by the University of Twente, captures CO2 from atmospheric air in a cheap and efficient way. The CO2, in turn, is used for growing algae, as a promising feedstock in the bio based economy. Another application is a closed cycle for storing solar and wind energy.
Between 1990 and 2015, due largely to a set of sweeping initiatives by the global community, the proportion of undernourished people in the world was cut in half. In 2015, U.N. member countries adopted the Sustainable Development Goals, which doubled down on this success by setting out to end hunger entirely by 2030. But a recent U.N. report shows that, after years of decline, hunger is on the rise again.
Epic disasters like Hurricanes Harvey, Irma and Maria (like Katrina and Sandy before them) illuminate the extraordinary vulnerability of our cities and towns. Yet those named storms represent just a fraction of the problem. The US now averages 129 disasters each year, up from 51 per year before the turn of the 21st century.
Now, according to USC scientists, it turns out that metal-organic frameworks can conduct electricity in the same way metals do. This opens the door for metal organic-frameworks to one day efficiently store renewable energy at a very large, almost unthinkable scale. “For the first time ever, we have demonstrated a metal-organic framework that exhibits conductivity like that of a metal. The natural porosity of the metal-organic framework makes it ideal for reducing the mass of material, allowing for lighter
Donald Trump began his presidency by purging the White House website of any references to climate change. In March he signed an executive order to review the Clean Power Plan, an Obama-era legislation that regulates greenhouse gas emissions. And over the summer Trump discussed removing the U.S. from the landmark 2015 Paris Climate Accord, an agreement among some 195 countries to moderate climate change.
Pruitt followed up on the March EO on Tuesday, announcing the EPA would repeal the Clean Power Plan…
Noah Diffenbaugh, a professor of earth system science at Stanford, studies the links between single extreme events and climate change. Notably, in several earlier papers, he and his coauthors concluded that human-influenced global warming “very likely” contributed to California’s recent five-year drought.
The Northern California fires are an ongoing event that he hasn’t analyzed and can’t draw any firm conclusions from yet, he stresses. But he notes that the drought killed “millions of trees”…
Dr Wesselbaum says the research makes clear that global migration patterns are increasingly being driven by climate change, and this raises crucial issues for policy makers. “It is clear climate migration is a global issue that needs cross-country discussion. Both developed and at-risk countries need more planning and policy to prepare for what is likely to be a growing trend of people wanting to move from countries experiencing climate change. “Climate refugees have yet to be recognised officially…
STORM enables scientists to examine, over multiple decades, the details of where rainfall occurs and how much fell on a per-minute basis. To date, Singer and Michaelides have used it to identify real climate change over a broad region, but they are in the process of coupling STORM to a runoff model to explore scenarios of climate change and how they might really affect the magnitude and the frequency of runoff.
At the tide pools, Hartney was on a mission to tell the story of the photogenic goosenecks, whose formerly sturdy shells are being compromised by dropping pH levels in the Pacific Ocean. Telling that story with punch, he learned in Science & Memory, meant capturing an amazing image of the barnacles. Determined, he took another step, carefully avoiding the slippery kelp.
