Halliburton reaches $1B Gulf oil spill settlement Last Updated on 2014-09-03 10:40:08 EW ORLEANS (AP) — Halliburton's agreement to pay more than$1 billion to settle numerous claims involving the 2010 BP Gulf of Mexico oil spill could be a way for the company and victims of the spill to avoid years of costly litigation — if all the pieces fall into place. A federal judge still has to approve the settlement. That same judge has rulings pending on the extent to which parties, including Halliburton, were negligent in the deadly explosion of the Deepwater Horizon offshore oil rig. Those rulings could affect plaintiffs' decisions on whether to participate in the settlement, which was announced Tuesday. CLICK HERE TO READ MORE More »
EIA mapping tool shows which U.S. energy facilities are in areas at risk of flooding Last Updated on 2014-08-07 10:15:28 Source: U.S. Energy Information Administration A new component of EIA's Energy Mapping System allows users to view critical energy infrastructure that may be vulnerable to coastal and inland flooding. These new map layers enable the public to see existing energy facilities that could potentially be affected by flooding caused by hurricanes, overflowing rivers, flash floods, and other wet-weather events. The mapping tool combines flood hazard information from the Federal Emergency Management Agency(FEMA) with EIA's existing U.S. Energy Mapping System that shows power plants, oil refineries, crude oil rail terminals, and other critical energy infrastructure. The maps can help readers understand what energy infrastructure assets are currently exposed to flood risk. The maps show areas that have a 1% and 0.2% annual chance of flooding (essentially a 1-in-100 and 1-in-500... More »
Climate Central visualizations of sea level rise Last Updated on 2014-06-24 10:48:00 By 2300, these iconic cities could be underwater. By Eric Holthaus   Last week, researchers announced that six major glaciers in West Antarctica have “passed the point of no return” and have begun “early-stage collapse.” It’s the kind of news we’ve come to expect from climate change, but the stark language and eye-popping implications made the news feel a little bit different. To me, “collapse” and “point of no return” conjures up the mental image of humanity riding a freight train off a cliff. While those words are surely frightening, in this case the good news (if you can call it that) is that full-on collapse and the resulting 10 to 13 feet of sea level rise from an Antarctica with less ice will be a relatively slow process, at least on the scale that you or I could perceive in our lifetimes. Still, the... More »
Image Slideshow: 20 Big U.S. Cities that Should Worry About Sea Level Rise Last Updated on 2014-06-10 18:25:17 20 Images By Alana Range Sea level rise — we've heard about it, but what does it actually mean, and how will it affect you, and the community where you live? Independent research has already predicted that by 2100, sea level may rise by one meter, due to a combination of the melting of land-based ice sheets and the warming oceans (when water warms, it expands). That gives us about 89 years until high tide is lapping at the door of many residents of Virginia Beach, New Orleans, and Miami, where some may need to find new homes on higher ground. But we already knew that. A new study published by Climate Central's Ben Strauss and the University of Arizona's Jeremy Weiss and Jonathan Overpeck, takes a closer look at the problem of sea level rise. According to their research, rising sea levels could threaten an average of nine percent of the land within 180 U.S.... More »
Sea Level Rise Contributors Last Updated on 2014-06-10 18:13:21 This activity has been selected for inclusion in the CLEAN collection. This web page from the National Snow and Ice Data Center contains two related visualizations. The first visualization gives an estimate of the percent contribution to sea level change since the 1990s from three contributors - small glaciers and ice caps, the Greenland Ice Sheet and the Antarctic Ice Sheet. The second visualization shows the cumulative contribution to sea level from small glaciers and ice caps plotted with the annual global surface air temperature anomaly. Explore >> State of the Cryosphere   Teaching Tips Global sea level rise is a result of both ocean thermal expansion and glacier melt. This graphic could serve as a great introduction to help students identify how glaciers contribute to sea level rise via volume and area. An explanation of how scientists compute this is... More »
