March 4th week 2015 current affairs

1) IEA report on global CO2 emissions from energy sector

  • Global emissions of carbon dioxide in the energy sector stalled in 2014, breaking steady rises over the past four decades except in years with an economic downturn, the International Energy Agency said on 13th March. Emissions of carbon dioxide were flat at 32.3 billion tonnes in 2014 from 2013, according to the IEA.
  • The Paris-based IEA, which advises governments of developed nations, said the halt in emissions growth was linked to greener patterns of energy consumption in China, the top carbon emitter ahead of the United States, and in developed nations.
  • A summit in Paris is due to agree a deal to limit global emissions, blamed by a U.N. panel of climate scientists for causing more heatwaves, floods and rising sea levels. The IEA said that carbon emissions had been flat or fallen only three times since it started collecting data 40 years ago, previously always linked to economic slumps – in the early 1980s, 1992 and 2009. In 2014, however, the global economy expanded by 3 percent.

2) North Korea test fired missiles

  • North Korea on 2nd March fired two short-range ballistic missiles into the sea. North Korea regularly conducts such test firings of missiles, rockets and artillery. It launched two missiles from North Korea’s west coast flew about 500 kilometers (310miles) before landing in waters off the east coast. During the 2013 drills, tension rose amid North Korean rhetoric that included vows of nuclear strikes on Washington and Seoul.
  • North Korea last year conducted an unusually large number of missile and other weapons tests, drawing protests from South Korea. The North still proposed a set of measures that it said would lower tensions, but South Korea rebuffed them, saying the North must first take steps toward nuclear disarmament.
  • 1950-53 Korean War ended with an armistice, not a peace treaty. About 28,500 American soldiers are deployed in South Korea as deterrence against potential aggression from North Korea.

3) World’s first fully-electric Comm satellites launched

  • US-based Space Exploration Technologies (SpaceX) has successfully launched a Falcon 9 rocket carrying the world`s first all-electric communications satellites into orbit. Blasted off from the Cape Canaveral Air Force Station in California on March 1, the rocket carried two satellites, built by Boeing, for French satellite provider Eutelsat and Asia Broadcast Satellite (ABS). The satellites will rely entirely on energy-efficient electric ion engines to maintain their orbit for up to two decades.
  • The satellites are outfitted with all-electric engines rather than conventional rocket thrusters to reach and maintain orbit. This reduces the weight of the satellites to the point where both could be launched at once. The downside is that it will take the satellites months to reach geostationary orbit. SpaceX is scheduled to launch at least two more Falcon 9 rockets this year.
  • The next launch is scheduled for March 21 when a Falcon 9 will deliver a communications satellite into orbit for Thales Alenia Space and the government of Turkmenistan.



4) Mars ocean was bigger than the Arctic: NASA

  • Mars once had a body of water bigger than Earth`s Arctic Ocean and vast enough to cover the entire surface of the planet, NASA scientists said in a study released
  • The new research, providing estimates on the quantity of water on the Red Planet, is based upon detailed observations of two slightly different forms of water in Mars` atmosphere, and was published in the journal Science. The study said that the Red Planet was once covered in a liquid layer 450 feet (137 meters) deep, occupying almost half of Mars` northern hemisphere. In some regions, water depths were greater than a mile (1.6 kilometers), NASA scientists said. The study also showed that the vast majority of Martian water — 87 per cent — has been lost to space.
  • The new estimate is based on detailed observations of two slightly different forms of water in Mars` atmosphere. One is the familiar H2O, made with two hydrogen atoms and one oxygen. The other is HDO, a naturally occurring variation in which one hydrogen is replaced by a heavier form, called deuterium. By comparing the ratio of HDO to H2O, scientists were able to measure the enrichment and determine how much water has escaped into space.
  • NASA said its researchers were especially interested in regions near the north and south poles, because the polar ice caps are the planet`s largest known reservoir of water.

2) ISRO study on Sunderbans

  • The Indian Sunderbans has lost 3.71 per cent of its mangrove and other forest cover, while losing 9,990 hectares of its landmass to erosion in one decade, according to a satellite analysis conducted by the Indian Space Research Organization.
  • As much as 1,607 hectares of the eroded area had vegetation, says the study comparing satellite data from February of 2003 and 2014. During the 10 years, 216 hectares of landmass had been added, of which 121 hectares has green vegetation.
  • The Eastern Zone Bench of the National Green Tribunal, which is hearing a case of environmental violations in the Sunderbans, directed holding the study.
  • The study shows that about 95.14 per cent of the green cover has not undergone gone any change, while fresh vegetation has come up in 1.1 per cent of the entire area.
  • The satellite mapping, which has not gone into the details of the reason for loss of green cover, says the depletion may be due to natural and anthropogenic (human intervention) processes. The 9,600-sq.km Indian Sunderbans is highly susceptible to coastal erosion and coastal land dynamics. A recent World Bank report pointed out that the carrying capacity of the landmass had exceeded with the population density of over 1,000 a sq.km.

2) Norway declared climate action plan

  • Norway on 27th March jointed the race of rich nations including Switzerland and European Union (EU) countries in submitting their respective `climate action plans` well in time. Norway submitted its Intended Nationally Determined Contribution (INDC) to the UNFCCC promising to cut at least 40% of its greenhouse gas emissions by the year 2030 compared to 1990 level.
  • Norway`s INDC is at par with the EU`s promise but less than that of Switzerland that promised to reduce its greenhouse gas emissions by at least 50% by 2030 from its 1990 level. Switzerland was, in fact, the first country that had submitted its climate action plan to the UN body.
  • Norway, however, promised that the country will consider taking a commitment "beyond an emission reduction of 40% compared to 1990 levels" if it can contribute to a global and ambitious climate agreement in Paris..
  • The country also noted that the solution with the EU means that the 40% emission reduction will be implemented in Europe, without the use of international market mechanisms outside of the EU and Norway.
  • The EU had in its INDCs, submitted in the March 2015 pledged that this group of 28 countries would work to reduce domestic emission of greenhouse gases by 40% from their 1990 level by the year 2030.
  • Besides, the EU had also committed for a regular review and strengthening of its mitigation commitments consistent with a long-term goal to curb emissions.
  • Under the INDCs, all countries are expected to submit their `nationally determined contribution` in terms of their mitigation (emission cut) and adaptation goals well in advance ahead of the Paris climate talks, scheduled for December, where a new climate deal is expected to be signed.
