  • This year Arctic temperatures continued to increase at double the rate of the global temperature increase.
  • The current observed rates of sea-ice decline and rising oceanic temperatures were higher than at any other time in the last 1,500 years; this year’s Arctic sea-ice maximum, measured in March, was the lowest ever observed—at 14.42 million sq km, it was the lowest in the 38-year satellite record, beating 2015’s maximum of 14.517 mn sq km and 2016’s maximum of 14.52 mn sq km.
  • The sea-ice minimum, measured in September, was eighth lowest on record—at 4.64 mn sq km on September 13. This was 1.58 mn sq km below the 1981 to 2010 median extent for the same day. The date of the minimum ice extent for 2017 itself was two days earlier than the average such date.
  • What is more worrying is that even if countries manage to keep the global temperature rise to under 2-degree C, they would still not be able to reverse the ice-melt cycle.


2 . NGT bans plastic in Haridwar, Rishikesh, Uttarkashi.
  • River Ganga is soon going to be plastic free, as National Green Tribunal (NGT) in a major development has took an important step in the matter.

  • A bench headed by NGT chairperson Justice Swatanter Kumar also banned the sale, manufacture and storage of such items till Uttarkashi.
  • Moreover, the special tribunal has also made a provision for  imposition of a fine of Rs 5,000 on those violating the order.
  • The NGT passed the direction after noting that despite its earlier order, plastic was being used in these areas causing pollution to the river.
  • Earlier in August, the green panel had imposed an interim ban on use of non-biodegradable plastic bags which are less than 50 microns in Delhi.

  • Tuirial HEPP is the biggest power project located in Mizoram and will feed the entire energy to be generated to the home State.
  • The State’s current demand of electricity is 87 MW and this is being met by the mini power projects and availability of its share of power from central sector projects.
