Alaska sees record temperatures in heatwave
An "all-time high" temperature record has been set in the US state of Alaska, despite much of the country sitting in the Arctic circle. Temperatures peaked at 32.22 Celsius (90F) on 4 July at an airport

Contrasting patterns of early twenty-first-century glacier mass change in the Himalayas
Glaciers are among the best indicators of terrestrial climate variability, contribute importantly to water resources in many mountainous regions and are a major contributor to global sea level rise. In

Himalayan glaciers in the balance
A measurement by satellite altimetry shows the Himalayan glaciers to be losing mass at only moderate rates, but raises broader questions about other methods for estimating mass balance.

Arctic sea ice may vanish in 10 years
Due To Global Warming, Meltdown Is 50% Faster Than Estimates: Experts London: Arctic sea ice could vanish within 10 years as it is melting much faster than previously believed, thanks to global warming,

Relative outcomes of climate change mitigation related to global temperature versus sea-level rise
A modelling study shows that cutting greenhouse-gas emissions has the potential to stabilize global temperature increases, but predicts that sea level will continue to rise for centuries, and rapidly so,

Massive Greenland surface ice cover melt picked up by satellites
Greenland's surface ice cover melted this month over a larger area than ever detected in more than 30 years of satellite observations, NASA said recently. According to measurements from three separate satellites analyzed by NASA and university scientists, an estimated 97 per cent of the ice sheet surface thawed at some point in mid July, the agency said in a statement. “This was so extraordinary that at first I questioned the result: was this real or was it due to data error?” said NASA's Son Nghiem.

Govt oversight needed in religious tourism
Environmentalists are demanding greater environmental management of religious tourism. The death of 98 pilgrims in the Amarnath Yatra has highlighted the need to ensure better man-management in these ecologically-fragile regions. Already, three lakh pilgrims have visited the Amarnath shrine while the number in 2011 was around 7.5 lakhs. Environmentalist Prof. Vikram Soni of the Jamia Milia University points out that such large numbers of yatris are unsustainable given the high altitude and the danger of landslides hitting this area which could result in heavy loss of life.

“Indication of global warming”
A massive iceberg — twice the size of Manhattan — has broken off of a glacier in Greenland, according to NASA satellite imagery, in what could be the latest indication of global warming. The images released on Wednesday show the massive chunk of ice breaking off of the Petermann Glacier on the north-western coast of Greenland. The glacier produced a similar ice island twice as large in 2010.
