Arctic Report Card: Update for 2013 - Tracking recent environmental changes, with 18 essays on different aspects of the environment, by a international team of 147 scientists from 14 different countries, with an independent peer-review organized by the Arctic Monitoring and Assessment Programme of the Arctic Council.
Every day Mumbai produces enough sewage to fill 4,500 Olympic-size swimming pools. Despite the many modern comforts of Mumbai, the sewer system is outdated and is still cleaned by hand. At least once a year the manhole covers are removed and a worker is lowered down with only a helmet for protection. The worker then scoops out the sludge consisting of both human and industrial waste that has been collecting in the pipes. It is not uncommon for Indian sewer workers to become ill or die from the toxic fumes. Indian Parliament recently passed a law in an effort to improve these poor working conditions, but many are doubtful that the new measures will make a difference.
his visualization shows the position of the sun's magnetic fields from January 1997 to December 2013. The field lines swarm with activity: The magenta lines show where the sun's overall field is negative and the green lines show where it is positive. A region with more electrons is negative, the region with less is labeled positive. Additional gray lines represent areas of local magnetic variation.

Brilliantly executed with innovative gameplay and built from the ground up for the iPhone, iPad & Android, Plague Inc. evolves the strategy genre and pushes mobile gaming to new levels.
Blue curve: Global temperature reconstruction from proxy data of Marcott et al, Science 2013. Shown here is the RegEM version – significant differences between the variants with different averaging methods arise only towards the end, where the number of proxy series decreases. This does not matter since the recent temperature evolution is well known from instrumental measurements, shown in red (global temperature from the instrumental HadCRU data). Graph: Klaus Bitterman.
