Arctic Biome

  • Arctic Tundra as a Carbon Source: The Arctic Boreal Zone (ABZ), including the Arctic tundra, is shifting from a carbon sink to a carbon source due to increased wildfires and permafrost thaw.

  • NOAA’s 2024 Arctic Report Card: Confirms that frequent fires and fossil fuel pollution are turning the Arctic tundra into a carbon source.

  • Nature Climate Change Study (2025): Found that over 30% of the ABZ has stopped sequestering carbon and is now releasing it.

  • Permafrost Thaw: Rising temperatures cause permafrost to thaw, releasing carbon dioxide and methane, accelerating global warming.

  • Wildfire Feedback Loop: Wildfires release carbon, increasing global warming, which thaws more permafrost, leading to more fires and emissions.

  • Key Areas of Carbon Emission: Alaska accounts for 44% of new ABZ emissions, with northern Europe and Siberia contributing 25% and 13% respectively.

  • Loss of Carbon Absorption: Carbon emissions from the longer, non-summer months in the ABZ have surpassed carbon dioxide absorption during the summer.

  • Extreme Weather Events: Wildfires are increasing in frequency and intensity, releasing large quantities of carbon into the atmosphere.

  • India’s Involvement: India studies climate impacts in the Arctic via its Himadri research station and participates in the Arctic Council, focusing on sustainable development.

  • Global Wildfires: Fires in Texas, Oklahoma, California, and Japan released substantial carbon, highlighting the global scale of carbon emissions from wildfires,

Ottawa Treaty

  • Withdrawals from the Ottawa Convention: Several NATO members, including Poland, Finland, Estonia, Latvia, and Lithuania, are withdrawing from the 1997 Ottawa Convention (Landmine Treaty).

  • Reason for Withdrawal: Increased security threats from Russia, amid the Russia-Ukraine war, are the primary reason. Countries fear Russia may re-arm during a ceasefire and pose a greater danger. They also want to level the playing field with Russia, which is not a signatory to the treaty.

  • Ottawa Convention (1997): It bans the use, production, stockpiling, and transfer of anti-personnel landmines. Signatories must destroy stockpiles within 4 years, clear mined areas, and assist victims.

  • Impact of Withdrawals: Countries can resume producing, using, stockpiling, and transferring landmines.

  • Funding Cuts: Global demining efforts are suffering from significant cuts in US funding. The US has historically been the largest funder of mine action.

  • Civilian Victims: Over 80% of landmine victims are civilians. Ukraine is now the most mined country globally, with a high number of civilian casualties.

  • Stockpile Obligations: The convention requires countries to destroy landmine stockpiles within four years, but compliance is not universal.

  • Cluster Munitions: Some countries withdrawing from the Landmine Treaty are also considering leaving the Convention on Cluster Munitions. The US, which is not a signatory, transferred cluster munitions to Ukraine in 2023.

Bear Market

  • Definition: A bear market is characterized by a sustained decline of 20% or more in a stock market index or individual security from a recent peak.
  • S&P 500: The S&P 500 recently briefly entered bear market territory for the first time since 2022.
  • Investor Sentiment: Bear markets are typically associated with widespread investor pessimism and large-scale selling of assets.
  • Causes: Bear markets can be triggered by weak economic conditions, anticipated slowdowns, overvalued markets, or external events like wars or oil supply shocks.
  • Recession Link: Bear markets often precede recessions (economic slowdowns), but not always.
  • Frequency: Historically, US stocks have entered bear market territory roughly every 6 years.
  • Duration: In the US, bear markets have lasted about 18.9 months on average.
  • Global Examples: The Indian stock market experienced a severe bear market during the 2008 global financial crisis, with the Nifty 50 index dropping over 35%.
  • Investor Action: A “bear” is an investor who expects prices to decline and sells borrowed securities hoping to buy them back cheaper later (selling short).
  • Market Correction: A market correction is a decline of at least 10%, while a bear market is a decline of at least 20%.

Akash SAM

  • India offers Akash SAM to UAE: India has offered its indigenous Akash air defence missile system to the United Arab Emirates (UAE)
  • Increased Defence Cooperation: India and the UAE aim to strengthen bilateral defence cooperation, including military exercises, training exchanges, defence-industrial collaboration, joint projects, R&D, and technology transfer.
  • Export Push: India is actively promoting the export of Akash, Pinaka, and BrahMos missile systems to friendly nations, particularly in the Gulf and ASEAN regions.
  • Akash SAM Features: Akash is a short-range surface-to-air missile with a range of 4.5 to 25 km, designed to protect vulnerable areas from air attacks, capable of engaging multiple targets and has ECCM features.

The Universe’s Mirror

  • CP Violation Confirmed in Baryons: CERN’s LHCb experiment has confirmed Charge-Parity (CP) violation in baryons, specifically the lambda-b (Λb) particle. This is the first discovery of CP violation in baryons to surpass the five-sigma statistical threshold.

  • What is CP Violation? It’s a difference in the behavior of matter and antimatter under combined charge conjugation (C) and parity transformation (P). Ideally, matter and antimatter should behave identically.

  • Lambda-b Baryon Decay: Scientists observed the lambda-b baryon decaying into a proton, a kaon, and two pions. A difference in decay rate between the lambda-b baryon and its antimatter counterpart signifies CP violation.

  • Matter and Antimatter Basics: Matter has mass and occupies space, composed of atoms and molecules. Antimatter consists of particles that are mirror counterparts of matter, with opposite electric charge.

  • Matter-Antimatter Interaction: When matter and antimatter collide, they annihilate each other, producing gamma rays.

  • Baryon Asymmetry Importance: The universe’s dominance of matter over antimatter (baryon asymmetry) remains a significant unsolved puzzle in physics.

  • Antimatter Uses: Positrons are used in PET scans for cancer detection. CERN produces nanograms of antimatter annually for research.
