    In news: Opium Wars

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Opium Wars

    Mains level: World History: Decolonization in Asia

    opium war

    Central Idea

    • The Opium Wars, waged by European colonial powers on China, exemplify how opium, as an inanimate object, became a powerful historical agent under specific social and political circumstances.

    Possible mains question:

    Q. Discuss the historical significance of opium as a powerful agent in shaping world history, with a focus on its role in the Opium Wars and its impact on colonialism and Chinese society.

    Story of Opium and Tea

    opium

    • Tea’s Introduction to Europe: Tea, originating in China over 2,000 years ago, became popular among the British elite in the mid-17th century and transcended class barriers to become the quintessential British beverage.
    • Trade Deficit with China: However, the British East India Company faced a trade deficit with China due to the import of tea.
    • Opium as a Solution: In 1763, the British acquired a monopoly on opium production and trade, which was already in demand in China. Selling opium to China from their rapidly growing colony in India helped offset the trade deficit caused by tea imports.

    Opium Cultivation in India

    • Rapid Growth: Under the British Opium Department, opium production in India saw a massive increase, rising almost 800% within a century. India’s total opium exports to China increased a hundred-fold between 1780 and 1880.
    • Selective Selling: Interestingly, while India grew all the opium, the British avoided selling it in their own colony, choosing instead to push it into Chinese society.

    China’s Addiction and Socio-economic Crises

    • Addiction Spreads: The highly addictive and debilitating drug led to widespread addiction among China’s upper classes and literati, causing socio-economic crises.
    • Decline of Qing Dynasty: The ruling Qing dynasty’s inability to curb opium trade eroded the machinery of the state and legitimacy of China’s governance.

    The Opium Wars

    • Discovery of Opium: In 1839, after discovering his son’s opium use, the Qing Emperor launched a crackdown, leading to tensions with British opium traders in Canton.
    • First Opium War (1839-42): British forces arrived in China to protect “free trade,” leading to a series of defeats for China. The Treaty of Nanking forced China to compensate British opium traders, cede Hong Kong, and open more ports for European trade.
    • Second Opium War (1856-60): Triggered by a conflict between a Chinese official and British traders, the war further expanded European presence in China and legalized opium trade.

    Opium as a Historical Agent

    • Colonialism and Opium: The Opium Wars epitomized colonialism in Asia, generating immense profits for colonialists at the expense of Indian labor and Chinese sobriety.
    • Continued Impact: Opioid crises worldwide show opium’s capacity to transcend social classes, making it a historical force with tragic consequences.
  • Climate Change Impact on India and World – International Reports, Key Observations, etc.

    What are Marine Heat Waves (MHWs)?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Marine Heat Waves

    Mains level: Read the attached story

    heat wave

    Central Idea

    • MHWs have engulfed regions like the northeast Pacific, southern Indian Ocean, the Atlantic, and the Mediterranean, as reported by Mercator Ocean International.
    • In April, the Sea Surface Temperature (SST) peaked at 21.1 degrees Celsius, breaking the previous record set in 2016.

    What are Marine Heat Waves (MHWs)?

    • While we often associate heatwaves with the atmosphere, they can also occur in the ocean, known as Marine Heatwaves (MHWs).
    • These prolonged periods of excessively warm sea surface temperatures (SST) can have significant consequences for marine ecosystems and industries.
      • SST is the temperature of the top layer of the ocean, typically measured at a depth of 1 millimeter to a few meters using buoys.

    • MHWs can happen in both summer and winter, with “winter warm-spells” affecting specific regions and species.

    How are MHWs measured?

    • Threshold Criteria: A marine heatwave is characterized by seawater temperatures exceeding a seasonally-varying threshold (often the 90th percentile) for at least 5 consecutive days.
    • Continuity of Events: Successive heatwaves with gaps of 2 days or less are considered part of the same MHW event.

    heat wave

    Causes of Marine Heatwaves

    • Air-sea heat flux: Ocean currents and air-sea heat flux are common drivers of MHWs, leading to the build-up of warm water in specific areas.
    • Influences of Wind and Climate Modes: Wind patterns can enhance or suppress MHWs. They influence the likelihood of events occurring in certain regions.
    • Large-Scale Climate Drivers: Events like the El Nino Southern Oscillation (ENSO) can also contribute to the formation of MHWs.
    • Intensification with Global Warming: Rising global temperatures have resulted in longer-lasting, more frequent, and intense MHWs in recent decades.
    • Human Influence: 87% of MHWs can be attributed to human-induced warming, with the oceans absorbing significant amounts of heat due to greenhouse gas emissions.
    • Oceans as Heat Sink: Oceans have absorbed 90% of the additional heat caused by greenhouse gas emissions, increasing global mean sea surface temperature by nearly 0.9 degrees Celsius since 1850.

    Impacts of Marine Heatwaves

    • Ecosystem Structure: MHWs can disrupt ecosystem structure, supporting certain species while suppressing others.
    • Kelp Forest Destruction: MHWs along the Western Australian coast in 2010-2011 devastated kelp forests and fundamentally altered the ecosystem of the coast.
    • Economic Losses: MHWs can cause economic losses, particularly in fisheries and aquaculture industries.
    • Vulnerability of Temperature-Sensitive Species: Species such as corals are highly vulnerable to MHWs. The 2016 marine heatwaves in northern Australia caused severe bleaching of the Great Barrier Reef.

    Impact on Marine Ecosystems

    • Catastrophic Effects: MHWs have led to the death of numerous marine species, altered migration patterns, and caused coral bleaching, endangering coral reefs.
    • Coral Bleaching: High ocean temperatures in the tropical Atlantic and Caribbean in 2005 led to a massive coral bleaching event, impacting over 80% of surveyed corals, with severe consequences for marine life.
    • Invasive Species and Ecological Imbalance: MHWs fuel the growth of invasive alien species, disrupting marine food webs and posing threats to wildlife. Ex. Whale entanglements in fishing gear.

    Consequences for Humans

    • Amplifying Storms: Higher ocean temperatures associated with MHWs make storms like hurricanes and cyclones stronger, leading to severe weather events and flooding.
    • Threat to Coral Reefs: Half a billion people depend on coral reefs for food, income, and protection, but MHWs pose a grave threat to these ecosystems, impacting human livelihoods.
    • Socio-Economic Impact: Coastal communities are particularly vulnerable to the socio-economic impacts of MHWs, affecting fisheries and tourism.
  • Health Sector – UHC, National Health Policy, Family Planning, Health Insurance, etc.

    • It requested Twitter and other social media platforms to remove a video depicting the naked parade and sexual assault of two Manipur women.

    What is Section 69(A) of the IT Act?

    • Empowering Content Takedown: Section 69(A) allows the government to issue content-blocking orders to online intermediaries like ISPs, web hosting services, search engines, etc.
    • Grounds for Blocking: Content can be blocked if it is considered a threat to India’s national security, sovereignty, public order, or friendly relations with foreign states, or if it incites the commission of cognizable offenses.
    • Review Committee: Requests made by the government for blocking content are sent to a review committee, which issues the necessary directions. Such orders are typically kept confidential.

    Supreme Court’s Verdict on Section 69(A)

    • Striking Down Section 66A: In the case of Shreya Singhal vs. Union of India (2015), the Supreme Court struck down Section 66A of the IT Act, which penalized the sending of offensive messages through communication services.
