| Coastal Wetlands Could Disappear this Century Posted: 13 Dec 2010 10:46 PM PST “Using a rapid sea-level rise scenario, most coastal wetlands worldwide will disappear near the end of the 21st century. In contrast, under the slow sea-level rise projection, wetlands with low sediment availability and low tidal ranges are vulnerable and may drown. ” Quoted from the USGS press release.

| Arctic Environment is Lost Forever Posted: 13 Dec 2010 09:42 PM PST NOAA tracks environmental change in the Arctic and communicates their conclusions annually in their “Arctic Report Card.” This year they report that a “return to previous Arctic conditions is unlikely”. |
| Predicting Solar and Lunar Eclipses – in 100 BC Posted: 13 Dec 2010 09:40 PM PST Sometime around 100 BC, Greek “watchmakers” built a device that predicted the date and time of future lunar and solar eclipses. To build such a device they had to understand the math associated with the relative movement of earth and moon in relation to the sun – then build that into a clock-like mechanism. All of this was done while much of the rest of the world still believed in a “flat earth”. Who would have had the time or funding to build this in 100 BC? The device, now known as the Antikythera mechanism was lost at sea and discovered by divers in 1901. For decades investigators tried to figure out what it was used for. Now a guy builds one from Lego…… |

| Posted: 13 Dec 2010 09:20 PM PST National Geographic website has an article that reviews theories for the origin of Saturn’s rings. A new theory favored by many involves a moon crashing into the planet with the debris from the impact forming the rings. |
| The Great Solar Superstorm of 1859 Posted: 13 Dec 2010 09:18 PM PST “Between August 28 – September 6, 1859, humans experienced one of the most spectacular solar storms in the last 450 years. Reconstruction of this event from historical data has led space weather researchers in recent years to classify it as a Superstorm. Here’s what it was like:….” Quoted from the NASA article. |
| The Challenge of Flood Prediction Posted: 13 Dec 2010 09:12 PM PST A USGS hydrologist explains some of the challenges of predicting the stage of a flood and why predicting as accurately as possible is important. Related: Stream Discharge Monitoring and Hydrographs. |
