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

Extensive dynamic thinning on the margins of the Greenland and Antarctic ice sheets
Mass loss from the glaciers along the margins of the Greenland and Antarctic ice sheets is increasingly contributing to sea level rise. However, ice loss as a result of accelerated flow, known as dynamic thinning, is so poorly understood that its potential future contribution to sea level remains unpredictable.

Understanding future changes in snow and glacier melt runoff due to global warming in Wangar Gad basin, India
Himalayas has one of the largest concentrations of glaciers and permanent snow fields. These are sensitive to climate change. Snow and glacier runoffs are important sources of water for the Himalayan rivers. Due to steep slopes, all these streams are potential sites for hydropower generation.

How prepared are we to face climate-induced calamities?
For more than 40 years, Earth has been sending out distress signals. We have responded through staging processions on Earth days, holding seminars, passing environmental laws and forging a few international treaties, like in the 1992 Earth Summit in Rio de Janiero.

Use of ICT for adaptation to climate change
Mango buds, honeysuckle and muster-flower are blooming earlier in the winter. Foggy days are longer than in the past and northern part of Bangladesh is no more cooler. Cyclone and flood are becoming common and frequent every year. These are indications of a warming climate.

Hard science
While relatively little is known definitively about the glaciers of the Himalaya and Hindukush, what facts do exist need to be acknowledged as such.

Beyond sun and dung
Rajendra Pachauri heads TERI, The Energy and Resources Institute, based in New Delhi. An engineer of the railways in his early career, Pachauri went to the United States to earn a PhD in industrial engineering and another in economics, after which he returned to India in 1981 to work with TERI.

The need for a Southasian perspective
Climate change has become the defining issue of our time. It is a quintessential global matter, since its effects respect no national or regional boundaries. Climate change is also a challenge that compels a global and collaborative response. We are all literally in the same boat, cast adrift in increasingly tumultuous seas. Unless we pull the oars together we may not make it to shore.
