In recent years, the melting season in the Arctic has been ending later in the year, leading to less time for new ice to form. As a consequence, the total sea-ice extent in September 2016 was over 3m km² smaller than in September 1980, although not as small as in September 2012, the worst year on record. A recent graph tweeted by a PhD student showing a dramatic drop in global sea-ice area over the past three months has caused a stir in the climate science community, although the NSIDC reportedly takes issue with the way its Arctic and Antarctic data are combined. Less controversial but equally alarming is the NSIDC’s latest data release, which indicates that sea-ice extent in the Arctic is currently around 2m km² below average, the lowest November figure on record.
And we all know the reason - Climate Change. The man-made villain which has been causing extreme weather changes and rise in global temperature and sea-level. NASA has released a set of images that reveals the horrific images of climate change. See it for yourself.
Heavy monsoon rains have caused catastrophic flooding along the Ganges and other rivers in eastern and central India. At least 300 people died and more than six million were affected by the flooding, according to news reports. These images show a stretch of the Ganges near Patna.
Meltwater streams, rivers and lakes form in the surface of the Greenland Ice Sheet every spring or early summer, but melting began exceptionally early in 2016. Melting encourages further melting when ponds of meltwater develop, since they darken the surface and absorb more sunlight than ice does. Surface melt contributes to sea-level rise when the water runs off into the ocean and when it flows through crevasses to the base of a glacier and temporarily speeds up the ice flow.
Ice in the Beaufort Sea, off the Arctic Ocean, suffered significant fracturing and breakup by mid-April in 2016, considerably earlier than the late-May period when this usually happens. NASA ice specialists attribute the change to unusually warm air temperatures during the first months of the year and to strong winds caused by a stalled high-pressure system over the area. The thicker, multi-year ice that once covered the region has largely given way to seasonal, first-year ice that is thinner, weaker and more easily broken up by strong winds.
