International Year of Pulses 2016

Cryosphere Affects Global Climate

  • 70% water is stored as fresh water in glaciers

  • In terms of the ice mass and its heat capacity, the Cryosphere is the second largest component of the climate system (after oceans)

  • Its relevance for climate variability and change is based on physical properties, such as its high surface reflectivity (albedo) and the latent heat associated with phase changes, which have a strong impact on the surface energy balance.

  • Highly reflective and protect earth from getting warm

  • It reflects more sunlight than open waters

  • Changes in snow and ice cover affect air temperatures, sea levels, ocean currents, and storm pattern

  • Global-scale decline of snow and ice over many years, especially since 1980 and increasing during the past decade

  • Most mountain glaciers are getting smaller

  • Snow cover is retreating earlier in the spring

  • Sea ice in the Arctic is shrinking in all seasons, mainly in summer

Carbon Sequestration

Carbon Sequestration is the process by which CO2 is captured from the atmosphere for long term storage to slow down the accumulation of greenhouse gases

4 Colour Classification Scheme Based on Pollution Index

  • Red (severely polluting)

  • Orange

  • Green

  • White (least pollutant)


  • 1st flower grown in space

  • Red, blue, and green LED lights used to simulate sunlight - growth of the flower

International Solar Alliance

  • To bring solar rich 121 tropical countries located fully or partly between the Tropic of Cancer and Capricorn together to tap solar energy

  • Shared vision to bring clean, renewable solar energy within the reach of all

  • To augment solar power generation in these countries with a view to contribute global sustainable development

  • Achieve the objective of keeping global warming below 2 degree Celsius

  • Function from the Gurgaon based National Institute of Solar Energy (NISE)

6 Solid Waste Management Rules

  • Plastic Waste Management Rule, 2016

  • 15, 000 tonnes of plastic waste generated every day, out of which 9, 000 tonnes is collected and processed, but 6, 000 tonnes of plastic waste not collected.

  • Complete ban on polythene bags in 17 states and UTs

  • NGT imposed an ban on use of non-biodegradable plastic bags less than 50 microns in the entire national capital Delhi with a fine of Rs. 5, 000 on possession

  • First commitment period 2008 – 2012

  • Second commitment period 2013 - 2020

  • Target on GHG emissions

Kigali Amendment

  • India piloted the concept of two base lines and a differentiated phased down time schedule to factor in the needs of developing countries

  • First time in Montreal Protocol - concept of two baseline was adopted both for developed and developing countries

  • On India’s initiative, energy efficiency was included for the first time in the Montreal Protocol as an agreed finance solution while phasing down HFCs.
