Ice-free areas of Antarctica to increase by 2100

In News

Ice free areas may increase in Antarctica by 25% due to climate change, leading to drastic changes in the continent’s biodiversity, a study warns.

About the Study

  • Researchers, including those from University of Queensland (UQ) in Australia, investigated how ice-free areas in Antarctica may be affected by climate change.
  • Melting ice could create up to 17,000 square kilometre of new ice-free area across Antarctica – a 25% increase on current levels.
  • The majority of this melting would occur on the Antarctic Peninsula where the climate had already rapidly warmed.

Effect of ice-free area

  • Expansion of ice-free habitat could lead to new opportunities for Antarctic biodiversity.
  • The warmer conditions will also encourage invasive species to establish.

India gives $100,000 to UN Tax Fund

In News

India has contributed $ 100,000 to a UN fund to help developing countries actively participate in the discussion of tax issue.

Becoming the first country

UN Trust Fund for International Cooperation in Tax Matters (the UN Tax Fund) received its first financial voluntary contribution from India. Voluntary contributions for the fund have been called for by the UN and the committee since its establishment in 2006. Call for contributions was also emphasised in the Addis Ababa Action Agenda adopted at the third International Conference on Financing for Development in 2015.

Addis Ababa Action Agenda and the UN Tax Trust Fund

  • The Addis Agenda provides a global framework to ensure the effective mobilization of resources at the national and international level for sustainable development.
  • Implementation of the Addis Agenda  supports the implementation of the Sustainable Development Goals (SDGs) and is an integral part of the 2030 Agenda for Sustainable Development.
  • In Addis Ababa, UN Member States committed to work together to enhance the UN Tax Committee’s resources to strengthen its effectiveness and operational capacity.
  • The Addis Agenda also specifically called on the Member States to support the UN Tax Committee and its subsidiary bodies through the voluntary Trust Fund.
  • It is to supporting the increased participation of developing country experts at subcommittee meetings.

Uranus’ unusual rotation creates light switch effect

In News

A discovery was made based on the data from NASA’s Voyager 2 spacecraft that flew closely past Uranus the seventh planet from the Sun more than 30 years ago in January 1986.

The Study

  • Uranus’ magnetosphere, the region defined by the icy planet’s magnetic field and the material trapped inside it gets flipped on and off like a light switch every day as it rotates along with the planet.
  • When the magnetised solar wind meets this tumbling field in the right way, it can reconnect and Uranus’ magnetosphere goes from open to closed to open on a daily basis.
  • Magnetosphere is open in one orientation, allowing solar wind to flow into it.
  • It is later closed, forming a shield against the solar wind and deflecting it away from the planet.
  • Uranus’ rapid rotational change in field strength and orientation lead to a periodic open-close-open-close scenario as it tumbles through the solar wind.

Reconnection of magnetic fields is a phenomenon throughout the solar system. It is one reason for the Earth’s auroras.

Relation History

Relations between India and Portugal began amicably in 1947 after India’s independence and diplomatic relations were established in 1949. Bilateral ties however went into decline after 1950 over Portugal’s refusal to surrender its enclaves of Goa, Daman Diu and Dadra and Nagar Haveli on India’s west coast. By 1955, the two nations had cut off diplomatic relations, triggering a crisis which precipitated in the Indian annexation of Portuguese India in 1961. Portugal refused to recognise Indian sovereignty over the annexed territories until 1974 when, following the Carnation Revolution, the new government in Lisbon recognised Indian sovereignty with the signing of a treaty in New Delhi in December 1974, bilateral relations were restored.
