METHANESAT, A SATELLITE WHICH WILL ‘NAME AND SHAME’ METHANE EMITTERS

TOPIC: (GS3) ENVIRONMENT – SOURCE: INDIAN EXPRESS

MethaneSAT, a cutting-edge satellite designed for global methane emission tracking, successfully soared into space aboard a SpaceX Falcon 9 rocket from California. This launch signifies a crucial stride in combatting climate change, focusing particularly on the potent greenhouse gas, methane.

Significance of Tracking Methane Emissions:

  • Methane ranks as the second most prevalent greenhouse gas, following carbon dioxide, significantly impacting climate change.
  • Over the last two centuries, its atmospheric concentration has doubled, contributing to about 30% of climate warming since the Industrial Revolution.
  • Given its heat-trapping potency, addressing methane emissions is pivotal in tackling climate change and its detrimental effects on the environment and public health.

Objectives and Purpose of MethaneSAT:

  • Developed by the Environmental Defense Fund (EDF) in collaboration with Harvard University and partners, MethaneSAT focuses on tracking methane emissions, especially from fossil fuel operations, a major contributor to human-caused methane emissions.
  • By offering real-time data, MethaneSAT aims to pinpoint emission sources, monitor changes, and empower stakeholders to take targeted actions to effectively reduce emissions.

Technical Features and Capabilities:

  • Equipped with advanced technology, including a high-resolution infrared sensor and spectrometer, MethaneSAT can detect methane concentrations as low as three parts per billion.
  • Its sensitivity allows it to identify and track smaller emissions sources, previously unnoticed, while also identifying “super emitters” and monitoring emission changes over time.

Addressing Challenges in Methane Emission Monitoring:

  • Traditional satellite limitations in technology have historically hindered accurate methane emission tracking.
  • MethaneSAT overcomes these challenges by providing high-resolution data and advanced monitoring capabilities, offering a more accurate and comprehensive understanding of global methane emissions.

Data Analysis and Accessibility:

    • Data collected by MethaneSAT will be analyzed using Google’s cloud computing and AI technology.
    • The information will be made publicly accessible through Google’s Earth Engine platform, facilitating informed decision-making by researchers, policymakers, and the public.

Sources of Methane Emissions:

  • Human Activity: Approximately 60% of methane emissions are linked to human activities.
  • Wetlands: Natural sources, primarily wetlands, contribute about 40%.
  • Agriculture: Responsible for a quarter of emissions, with livestock and rice cultivation being major contributors.
  • Energy Sector: The second largest source, involving methane leaks from coal, oil, and gas infrastructure.
  • Household Waste: Decomposing household waste, especially in landfills, releases substantial methane quantities.

NOAA WARNS WORLD’S CORAL ON VERGE OF ‘WORST BLEACHING EVENT IN HISTORY OF THE PLANET’

TOPIC: (GS3) ENVIRONMENT – SOURCE: COMMONDREAMS

The National Oceanic and Atmospheric Administration (NOAA) has issued a warning about an imminent fourth mass coral bleaching event, putting marine biologists on high alert. This comes after months of extraordinary ocean heat due to climate change and the El Niño climate pattern.

Global Coral Bleaching Risk:

  • NOAA’s Coral Reef Watch experts suggest the entire Southern Hemisphere is likely to experience coral bleaching this year, indicating a severe global event, possibly unprecedented in history.

Causes and Impact of Coral Bleaching:

  • Coral bleaching occurs when corals expel symbiotic algae due to heat stress, leaving them pale and vulnerable to starvation and disease.
  • The consequences extend beyond coral health, affecting ocean ecosystems, fisheries, and tourism-driven economies relying on vibrant coral reefs.

Historical Context:

  • Previous global mass coral bleaching events occurred in 2010 and 1998, causing devastating effects on coral reefs worldwide.
  • The Great Barrier Reef, from 2014 to 2017, suffered significant coral loss, losing nearly a third of its corals.

Assessment Methods:

  • Scientists use sea surface temperature data and satellite imagery to assess coral bleaching risk.
  • Monitoring reef pixels helps identify regions experiencing widespread bleaching by surpassing critical heat stress thresholds.

Implications and Concerns:

    • The looming fourth mass coral bleaching event raises concerns about the long-term viability of coral reef ecosystems and associated socio-economic impacts.
    • Urgent action is needed to mitigate climate change and reduce stressors on coral reefs to safeguard these vital marine habitats.

What are Coral Reefs

  • Corals are marine invertebrates forming colonies, with each individual called a polyp.
  • They share a symbiotic relationship with algae (zooxanthellae), providing food through photosynthesis.
  • Australia’s Great Barrier Reef is the world’s largest, hosting diverse marine life.

What Causes Coral Bleaching?

  • Change in Ocean Temperature: Increased Ocean temperature due to climate change is the leading cause.
  • Runoff and Pollution: Storm-generated precipitation and runoff carry pollutants, bleaching nearshore corals.
  • Overexposure to Sunlight: High solar irradiance during high temperatures contributes to shallow water coral bleaching.
  • Extremely Low Tides: Exposure to air during extremely low tides can cause bleaching in shallow corals.

100 TALUKS IN KARNATAKA HIT BY DRINKING WATER CRISIS, SAYS CHIEF MINISTER

TOPIC: (GS2) POLITY AND GOVERNANCE– SOURCE: THE HINDU

Approximately 100 talukas in Karnataka are currently facing a severe drinking water crisis, leading to the deployment of water tankers for supply. Chief Minister Siddaramaiah, in response to the situation, conducted a videoconference, revealing that 98 out of 236 talukas are grappling with drinking water shortages due to drought.

Current Situation in Karnataka:

  • The State declared 223 talukas as drought-hit, impacting 7,408 villages and 1,115 urban local body wards with impending drinking water scarcity.
  • Private borewell owners have entered agreements to provide water to drought-affected villages and towns.
  • Chief Minister disclosed the allocation of ₹631 crore to aid 33.25 lakh affected farmers, recognizing extensive crop losses.

India’s Water Crisis:

Severity:

  • Limited Resources: India holds only 4% of the world’s freshwater despite a population exceeding 1.4 billion, causing immense stress.
  • Millions Affected: Over 160 million lack access to safe drinking water, and 200 million lack improved sanitation facilities.
  • Health Impact: 21% of communicable diseases are linked to unsafe water, with around 500 children under five dying from diarrhoea daily.
  • Polluted Rivers: More than half of India’s rivers are highly polluted, further reducing usable water sources.

Reasons:

  • Water Scarcity: Uneven rainfall patterns and reliance on monsoons worsen water shortages, especially in drier regions.
  • Overexploitation: Excessive groundwater extraction for agriculture and industry depletes aquifers faster than they can be replenished.
  • Pollution: Industrial waste, agricultural runoff, and untreated sewage contaminate surface water sources.
  • Infrastructure Gaps: Leaking pipes and inefficient water distribution systems result in significant water loss before reaching homes.

Way Forward:

  • Water Conservation: Public awareness campaigns promoting water-saving practices in homes and agriculture.
  • Infrastructure Upgrade: Investment in modern water treatment plants, leak detection, and efficient distribution systems.
  • Sustainable Management: Promotion of rainwater harvesting, groundwater recharge, and wastewater treatment for reuse.
  • Policy & Regulation: Enactment of stricter regulations on pollution control and water usage across different sectors.
  • Public-Private Partnerships: Collaboration between the government and private entities to develop innovative water management solutions.

By addressing these challenges, India can progress towards a more secure water future, ensuring the well-being of its citizens and the environment.
