Sea Level Rise vs Atmospheric CO2

A map showing what the coast lines of Western Europe will look like with a 20-metre sea level rise.
Manmade Carbon CO2 Pollution Has Already Put Us on Track for 20 Metres of Sea Level Rise

The bad news is that we’re all but certain to end up with a coastline at least this flooded: 20 metres or 69 feet The “good” news is that this might take 1000 to 2000 years (or longer/shorter), and the choices we make now can affect the rate of rise and whether we blow past 69 feet to beyond 200 feet.

Why has the Sun been so quiet?

The Sun ought be awash with activity right now.  But space scientists are baffled…  The Sun has reached its solar maximum: the point in its 11-year cycle where activity is at a peak.  Yet it has hit a lull.  And to see when the Sun was this inactive last… you’ve got to go back about 100 years…

A Rambling Geomagnetic Pole

Magnetic North made an unusual and historic shift.  For the first time in more than 220 years of map making, Ordnance Survey has noted that North lies East, and not West, of Grid north for parts of Southern Britain.  But how does this shift in magnetic field affect map reading in Scotland’s hills?

http://www.roboearth.org/ – The Matrix is Everywhere…

A photograph showing an old-fashioned computer screen showing a lot of data in green font type on the black screen background and the words "The Matrix has you..." is displayed in the centre.
What is RoboEarth?

A world wide web for robots to learn from each other and share information is being unveiled for the first time.  The eventual aim of the system is that both robots and humans will be able to upload information to the cloud-based database, which would act as a kind of common brain for machines.

CSI Scotland: Murder by the Loch – Studying the Forensics…

A colour drawing of Ross Priory - an early 19th-century country house, located west of Gartocharn, West Dunbartonshire, on the south shore of Loch Lomond, Scotland. The scene of the crime? Forensic science and murder meet by the Loch.
