  • Evidence of High Rainfall during Deccan Traps Volcanism

    deccan

    Central Idea

    • A team of scientists from IIT Kharagpur has discovered evidence of exceptionally high annual rainfall during the volcanic activity that formed the Deccan Traps in India around 66 million years ago.
    • Using a new technique called Nanoscale Secondary Ion Mass Spectrometry (NanoSIMS), the researchers analyzed the isotopic composition of fossil trees from the Cretaceous period.
    • They determined the isotopic composition of the rainfall-derived lake water.

    Nanoscale Secondary Ion Mass Spectrometry (NanoSIMS)

    • NanoSIMS is an advanced analytical technique to determine the composition and distribution of elements and isotopes at a microscopic scale.
    • It allows for high-resolution imaging and quantitative analysis of samples.
    • The technique involves bombarding the sample surface with a focused beam of primary ions.
    • This causes the ejection of secondary ions from the sample surface.
    • The secondary ions are collected and analyzed using a mass spectrometer.
    • The mass spectrometer separates the ions based on their mass-to-charge ratio and measures their abundance.

    Analysis and Findings

    • New Technique: The team used Nanoscale Secondary Ion Mass Spectrometry to analyze oxygen isotopes in fossil trees and measure the isotopic composition of the lake water derived from rainfall.
    • Depleted Oxygen Isotopes: The analysis revealed depleted oxygen isotope values, indicating higher tropical rainfall in India during the terminal Cretaceous period.
    • Link to Paleoclimatic Changes: The increase in rainfall closely corresponded to changes in paleo-atmospheric carbon dioxide levels, suggesting a potential underlying link between the two.

    Implications and Comparison

    • Atmospheric Carbon Dioxide Concentration: The eruption of Deccan Trap lavas released a significant amount of carbon dioxide, raising atmospheric levels to as high as 1,000 ppm.
    • Comparison to Modern Rainfall: The data from fossil trees indicated an annual rainfall of 1,800-1,900 mm, exceeding the average modern rainfall of 1,000-1,200 mm in most parts of peninsular India.
    • Climate Change Predictions: The findings align with predictions made by the Intergovernmental Panel on Climate Change (IPCC) for extreme warming scenarios, suggesting a correlation between high carbon dioxide levels and increased rainfall.

    Climate Models and Future Projections

    • Rising Carbon Dioxide Levels: Fossil fuel emissions have raised carbon dioxide levels from 280 ppm to about 420 ppm in 2023.
    • Impact on Rainfall: Climate models indicate that doubling carbon dioxide levels will intensify atmospheric circulation and subsequently increase rainfall.
    • IPCC AR6 Report: The report warns of a significant increase in the wettest day precipitation and tropical cyclone-associated rainfall if carbon dioxide emissions continue to rise unabated.

    Conclusion

    • The study provides evidence of high rainfall during the volcanic activity that formed the Deccan Traps in India millions of years ago.
    • The findings suggest a correlation between elevated carbon dioxide levels and increased rainfall, supporting predictions made by climate models for future climate change scenarios.

     

  • The challenge of Antimicrobial Resistance (AMR), and how to confront it effectively

    What’s the news?

    • Antimicrobial Resistance (AMR) is today reckoned among the most ominous threats confronting Global Public Health. There is an urgent need for a collective and comprehensive approach to address the global threat of AMR and the role of various stakeholders in prevention, control, and surveillance efforts is crucial.

    Definition

    • Antimicrobial resistance, means that certain drugs that were once effective in treating infections caused by bacteria, viruses, fungi, or parasites no longer work because the pathogens have become resistant to them.
    • In simpler terms, it is when the germs that make us sick become “immune” to the medicines we use to treat them.

    Prevalence of AMR

    • According to recent estimates, in 2019, 1.27 million deaths were directly attributed to drug-resistant infections globally. By 2050, up to 10 million deaths could occur annually.
    • If unchecked, AMR could shave US$ 3.4 trillion off GDP annually and push 24 million more people into extreme poverty in the next decade.
    • A 2022 study by the Indian Council of Medical Research (ICMR) revealed that resistance to broad-spectrum antimicrobials increases by 5% to 10% every year.

    AMR: A concern for global public health

    • Rising Resistance: The infections caused by the pathogens including bacteria, viruses, fungi, and parasites, are increasingly developing resistance to antimicrobial drugs which is becoming more challenging to treat effectively.
    • Treatment Failures: AMR can lead to treatment failures, as commonly used antibiotics, antivirals, antifungals, and antiparasitic drugs may no longer be effective against resistant strains.
    • Healthcare Impact: AMR increases the complexity and cost of treatment, prolongs hospital stays, and requires the use of stronger and more expensive drugs. Healthcare-associated infections caused by drug-resistant pathogens are a particular concern.
