First Sign of Coral Bleaching in Sydney

For the first time ever, coral population in Sydney Harbour is showing signs of bleaching due to warm waters.
The researchers discovered the first ever incident of 'paled coral colonies during routine monitoring at a number of locations in Sydney Harbour.
The researchers claimed that around 45% of harbour's hard corals has been devastated by warm waters.
Coral bleaching usually occurs when the temperature of sea water rises abnormally. Several factors are responsible for such warm waters like climate change, global warming, El Nino etc.

Early Melting of Ice Sheet

As per data, the seasonal melting of Greenland's vast ice sheet reached record levels this week with around 12 per cent of the ice sheet was melting, almost one month.
The record coincided with unusually warm weather in the Arctic territory, with temperatures at some weather stations on the ice reaching 10 degrees Celsius.
In Kangerlussuaq on Greenland's west coast, the mercury reached 17.8 degrees Celsius, one of the highest April temperatures in Greenland since records began in 1873.
Greenland ice loss contributed to a global average sea level rise of 25 millimetres (about an inch) between 1990 and 2010.

Greenland's ice Melt

As per geoscientists, Greenland sits over an area of abnormally hot mantle material that drives a widespread melting beneath the ice sheet and rapid ice flow over a distance of several hundred km.
The researchers had to go far back into the Earth's history to explain the reason for the melting base of the world's second largest ice sheet.

Illegal Gold Mining

Illegal gold mining in the Amazon has a devastating effect on indigenous people. First the miners bring disease, deforestation and even murder. Then communities are left to suffer deadly mercury poisoning.
In Brazil, new statistics reveal alarming rates of mercury poisoning.
Mercury poisoning is devastating tribal people across Amazonia.
Tribal people are especially susceptible to mercury poisoning due to the large amount of illegal gold mining taking place on their lands. Mercury is used to coalesce fine alluvial gold particles into an amalgam and separate it from sand and pebbles.
