  • Global Spread of H5N1 Bird Flu

    Why in the news?

    • Since 2020, the highly pathogenic H5N1 bird flu has been spreading globally, posing a significant threat to both birds and mammals.

    H5N1 Bird Flu: Details

    • H5N1 originated from a virus outbreak on a goose farm in China in 1996 and has since evolved into a highly pathogenic strain.
    • The virus quickly spread from Europe to Africa, Asia, North America, and South America, and most recently, it reached mainland Antarctica.
    • H5N1 is a subtype of the influenza A virus that causes severe respiratory disease in birds, known as avian influenza or “bird flu”.
    • Influenza A viruses are classified by subtypes based on the properties of their surface proteins, with H5N1 being one subtype.

    How widespread is it?

    • The virus has affected birds in over 80 countries, resulting in mass culling of poultry and wild birds.
    • Furthermore, it has now begun infecting mammals, including seals, sea lions, and marine mammals.
    • While humans rarely contract bird flu, those at risk are typically individuals who have extensive contact with infected birds at poultry farms.
    • Bird flu first broke out in Maharashtra in 2006.
    • The H5N1 virus led to the culling of millions of poultry so as to contain the virus. But it has resurfaced from time to time.

    Impact on Animals

    • Bird Species Affected: Numerous bird species, including Great Skuas and Barnacle Geese, have experienced significant mortality rates due to H5N1.
    • Endangered Species Threatened: Endangered birds like the California condors have been severely affected, with a notable percentage of the population succumbing to the virus.
    • Mammalian Casualties: H5N1 has crossed species barriers, infecting mammals such as foxes, pumas, skunks, and marine mammals like sea lions and dolphins.
    • Devastating Consequences: Mass mortalities of marine mammals, particularly elephant seals, have been reported, raising concerns about the long-term ecological impact.

    Factors behind Spread

    • Climate Change: Some scientists attribute the large-scale spread of bird flu to climate change, which alters bird behavior and facilitates the transmission of the virus.
    • Warmer Seas: Warmer sea temperatures have weakened marine mammal populations, making them more susceptible to disease outbreaks.

  • How much should developed countries pay for climate action?

    Why in the news? 

    As the climate bomb ticks, Global Climate negotiators are working on a new global climate finance budget ahead of COP29 in Baku this November.
    • In 2009, developed countries committed to paying $100 bn every year. However, they failed to do so.

    Context:

    • The 2022 climate change conference (COP 28) held in Sharm el-Sheikh decided to establish a Loss and Damage Fund. 
    • These funds would work as a “transition away” from fossil fuels, and a promise to triple global renewable energy capacity by 2030.
    • On March 22, a two-day meeting was concluded in Copenhagen, Denmark, the first minister-level climate meeting for this year, and a ‘New Collective Quantitative Goal’ was finalized.

    What is the New Collective Quantitative Goal (NCQG)?

    • NCQG represents the yearly sum that developed countries must gather from 2025 onward to finance climate action in developing nations.
    • It has to be higher than the $100 billion that developed countries, collectively, had promised to raise every year from 2020, but had failed to deliver.

     

    Collective Funds need to ensure effective Climate Action:

    • UN Climate Change Report (2021): According to a report by UN Climate Change, developing countries would need approximately $6 trillion annually between 2021 and 2030 to implement their climate action plans.
    • Estimation in Sharm el-Sheikh Agreement: The final agreement at Sharm el-Sheikh included estimates suggesting that a global transition to a low-carbon economy could require about $4-6 trillion annually until 2050.
    • Global GDP Percentage: While these estimates vary, an approximate range of $5-7 trillion annually is suggested to effectively address climate change. This would require deploying about 5-7% of the global GDP towards climate action.
    • Renewable Energy Capacity: Meeting the target of tripling renewable energy capacity, as agreed in Dubai, is estimated to cost $30 trillion by 2030, according to the International Renewable Energy Association (IRENA).

    Prospects for a Realistic New Annual Climate Finance Target:

    • Current Funding Shortfall: The UNFCCC, responsible for organizing climate meetings and facilitating the implementation of climate agreements, is facing a severe shortage of funds. Its budget is currently less than half funded, which hampers its ability to fulfill its mandate effectively.
    • Call for Increased Climate Finance: There is a call for developed countries to commit to significantly higher levels of climate finance. India, for instance, has called for the New Collective Quantitative Goal (NCQG) to be set at least at $1 trillion per year 
    • Need of Innovative Funding Sources: Simon Stiell, Executive Secretary of UN Climate Change, emphasized the need for innovative funding sources to meet the substantial financial requirements for climate action.  
    • Dependence on Contributions: The UNFCCC relies heavily on contributions from countries and voluntary organizations to carry out its work. 

    How will this money be used?

    • On-time Delivery: Ensuring effective delivery of the new funding is essential for achieving meaningful impact.
    • Transparent and Inclusive Monitoring: Developing countries emphasize the need for a transparent and inclusive process to monitor and measure the agreed-upon amount.  
    • Distribution Across Needs: The new funding is distributed across different climate action areas such as mitigation, adaptation, and addressing loss and damage as per need 

    Conclusion: Developed countries must commit to higher climate finance, possibly $1 trillion annually, for effective action. Innovative funding sources and transparent monitoring are crucial for impactful distribution across climate action areas.

    Mentor comments: The spectre of electricity shortages rises again as hot weather descends across the country. In recent years, increasingly unpredictable weather patterns and a fast-growing economy have led to big increases in electricity demand, the meeting of which reliably becomes a challenge. But some of the discourse in this context deserves greater scrutiny.

    Let’s learn. 

    —

    Why in the News?

    The recent unpredictable Weather Discourse and increase in Energy Demands around the coal sector in India needs a course correction.

    What are the recent challenges highlighted with coal?

    • Challenge with Logistics:
      • Shortage of Domestic Thermal Coal: It is the kind of Coal used in electricity generation, which is primarily blamed for the electricity shortage. Electricity shortage last year was about 840 million units due to poor monsoon, in turn leading to increased demand and reduced supply from some sources. 
      • Shortage of Logistics: According to the Ministry of Power advisory, the core challenge is insufficient logistics to move the coal to power plants. This leads to the second conflation, that the only alternative source is imports. 
    • The issue of imports:
      • Some thermal coal imports to blend with domestic coal may be required even if auctions are used. The question then is about how much of imports for which coal plants. 
      • India has been the major demand side driver of the global coal market. The higher imports is an indication of the preparations to meet the rise in demand of power. 
      • A mandatory blending of 6% imported coal, instead of the current blending levels, can increase the variable cost of coal-based electricity by 4.5%-7.5%. 
      • Indeed, as in the report on Annual Rating of Power Distribution Utilities, power purchase costs increased by 15% in FY23 due to increases in demand, coal imports, and prices of imported coal. 
    • The Issue with Generation and Location:
      • The plants that generate the most (pit-head plants) are situated close to mines, far away from ports, and do not face coal shortages. Shortages in periods of high demand are more likely in plants far away from mines which typically do not generate as much. 

    Way Forward:

    • Reducing Coal dependency: The discourse around coal shortages in the country needs course correction. It cannot be assumed that coal imports are the default way to address shortages. 
    • Increasing Accessibility: The fundamental challenge is to overcome the logistics bottlenecks that are preventing coal from reaching the locations where required. 
    • Government Interventions needed: In the interim, regulatory commissions and distribution utilities must ensure that all coal-based plants are alert to the possibility of coal shortages and identify the cheapest alternative sources which may not be imports to bridge the gap.

  • Discovery of Amino Acid unveils How Light makes Stomata Open in Plants

    Why in the news?

    Scientists from Nagoya University have made a discovery about the regulation of Stomatal opening in plants, a process vital for efficient photosynthesis by a type of amino acid threonine (Thr881).

    What are Stomatal Openings?

    • Stomata are microscopic pores on plant leaves crucial for gas exchange.
    • They particularly uptake carbon dioxide necessary for photosynthesis.

    How does Light make Stomata Open?

    • Research unveiled a novel regulatory mechanism involving the phosphorylation of the 881st threonine residue (Thr881) of the plasma membrane proton pump in response to red and blue light.
    • Phosphorylation, a process involving the addition or removal of a phosphate group from amino acids, acts as a regulatory switch, influencing protein structure and function.
    • The researchers focused on the phosphorylation of Thr881 and its role in stomatal opening.
    • They observed phosphorylation in response to both red and blue light conditions, highlighting the interplay between photosynthesis and light signaling.

    Significance of Thr881 Phosphorylation

    • Mutant studies confirmed the critical role of Thr881 phosphorylation in stomatal opening.
    • Plants expressing a mutant proton pump lacking Thr881 phosphorylation exhibited reduced stomatal aperture and transpiration rates, emphasizing the regulatory significance of this amino acid residue.
    • The study identified Thr881, along with Thr948, as crucial phosphorylation sites for the activation of the enzyme H+-ATPase, essential for stomatal opening.
    • Manipulating Thr881 could offer avenues for promoting plant growth, enhancing carbon dioxide absorption, and reducing fertilizer usage.
