Hurricane Hilary

Syllabus

  • Prelims –Geography

Context: Recently, Hurricane Hilary caused extensive damage in the United States.

Background:-

  • Hilary is the first tropical storm to hit Southern California in 84 years.

About Hurricane Hilary:-

IMAGE SOURCE: dailybreeze.com

  • Location: near the west coast of Baja California.
    • Baja California: The long Mexican peninsula bound by the Gulf of California in the east and the North Pacific Ocean in the west.

Origin and Trajectory:-

  • It originated as a Tropical Storm off the shores of Mainland Mexico.
  • This weather phenomenon rapidly transformed into a Category 2 hurricane and then into a Category 3 storm
  • Soon, it was officially designated as a Category 4 hurricane, nearly a day before its projected timeline.
  • This rapid intensification is anticipated to continue, leaving open the possibility of a Category 5 upgrade before eventual weakening. ( Cyclones forecast)

Categories of Hurricanes:-

  • Hurricanes are categorized on the Saffir-Simpson Hurricane Wind Scale based on their maximum sustained wind speeds.
  • The scale ranges from Category 1 (weakest) to Category 5 (strongest).
  • Each category represents a higher wind speed and potential for damage.

Possible Factors behind its intensification:-

Scientists expected climate change to not only spike the occurrence of such hurricanes but also make them more intense due to the following implications:-

  • Rise of the surface temperatures of the oceans: global mean sea surface temperature has gone up by close to 0.9 degree Celsius since 1850 and around 0.6 degrees Celsius over the last four decades.
  • Higher sea surface temperatures: it causes marine heat waves, an extreme weather event, which can also make storms like hurricanes and tropical cyclones more intense.
    • Marine heatwaves: they are extended periods of anomalously warm sea surface temperatures in the ocean.
  • El Nino: The situation has been worsened by El Nino, developing for the first time in seven years.
  • This has weakened the vertical wind shear in the eastern Pacific, allowing more hurricanes in the region.
    • El Nino: a weather pattern that refers to an abnormal warming of surface waters in the equatorial Pacific Ocean.

Risk or Threat:-

  • Unlike hurricane-prone states on the Gulf of Mexico, California and Mexico’s west coast lack experience in dealing with such events. (Bomb Cyclone)
  • Its expected landfall in the Baja peninsula of Mexico poses risks of landslides, flooding, and extensive damage due to the region’s geographical features and population density.

About Hurricane:-

  • Hurricanes are tropical storms that form in the Atlantic Ocean.
  • Wind speeds: at least 119 kilometers (74 miles) per hour.
  • Hurricanes derive their energy from the heat released when moist air rises and condenses into clouds and rain.

Key characteristics of hurricanes:-

  • Hurricanes form over warm ocean waters when the sea surface temperature is typically above 26 degrees Celsius (79 degrees Fahrenheit).
  • Low-Pressure Centre: Hurricanes have a well-defined centre of low atmospheric pressure, known as the
  • Strong Winds: winds can reach sustained speeds of at least 74 miles per hour (119 kilometers per hour) or higher.
  • Heavy Rainfall.

Mains:

The Role of Emotional Intelligence in Effective Leadership

Syllabus

  • Mains – GS 4 (Ethics)

Context: Emotional intelligence, or the ability to understand and manage one’s emotions and those of others, is crucial for effective leadership in this technology driven modern era especially for the good governance.

About Emotional Intelligence (EI):

  • Emotional Intelligence (EI) refers to the capability of a person to recognize, understand and manage own emotions, as well as to understand, manage and influence emotions of others. It is not always virtuous and can be used as a tool for positive and negative ends.

Elements of EI (as given by Daniel Goleman)

  • Self-Awareness: It is the skill of being aware of and understanding one’s emotions as they occur and as they evolve.
  • Self-Regulation: It is about controlling one’s emotions i.e. instead of reacting quickly; one can reign in one’s emotions and thus will think before responding.
  • Internal Motivation: It includes one’s personal drive to improve and achieve commitment to one’s goals, initiative, or readiness to act on opportunities, and optimism and resilience.
  • Empathy: It is an awareness of the needs and feelings of others both individually and in groups, and being able to see things from the point of view of others.
  • Social Skills: It is applying empathy and balancing the wants and requirements of others with one’s. It includes building good rapport with others.

Development of EI among civil servants:

  • Training: through practice and feedback, civil servants can learn from their mistakes using real life examples and reflection opportunities.
  • Experiential learning: Emotional and behavioral changes require life activities, which are primarily outside of the traditional classroom, and is commonly referred to as experiential learning.
  • Learning transfer: it refers to how people use what they learn in training for performance improvement.
    • Learning transfer seeks to reinforce and apply the information learned on the job immediately.
  • Support: Coaching, encouragement and peer support can assist with lasting change and positive development of EI competencies.

Significance of Emotional Intelligence in Civil/Public Services:

  • Better decision making: Biological evidence suggests that decision-making is neurologically impossible without being informed by emotions.
    • Therefore, EI furthers neutrality and impartiality when there is conflict of interest.
  • Better Communication: Emotionally intelligent people listen to other people and know how to communicate effectively (Goleman 1997).
    • Hence, an emotionally intelligent Civil Servant manages to execute policies effectively through better communication with public at large.
    • Empathy and integrity takes precedence over personal biases when one is emotionally sorted out.
  • Management of disruptive emotions– A civil servant while working in high-pressure environment often becomes subject to political pressure, life threats etc.
    • Only a public servant who is Emotionally Intelligent would be able to handle such pressures without succumbing to anger, depression or compromise.
  • Better execution of Policies– According to a research working with colleagues who are not self-aware can cut a team’s success in half and, lead to increased stress and decreased motivation.
  • Fosters Leadership– Self-awareness is at the core of everything. It describes the ability to not only understand one’s strengths and weaknesses, but to recognize emotions and the effect they have on herself (public servant) and her team’s performance.
  • More efficient administration: Because Emotional intelligence helps to –
    • Respond to situations very flexibly.
    • Take advantage of the right time and right place.
    • Make sense of ambiguous or contradictory messages.
  • Build Trust with people: Emotionally intelligent people listen to other people’s emotions and can empathize with them.
    • Emotionally intelligent people act ethically and build trust through integrity and reliability.
  • Better Governance: All public service is people service. Relationships are at the heart of governance.
    • To the extent that public administration mirrors the hearts and minds of people, it is governance.
    • EI helps in building relationships with people and ensures better implementation of public schemes.

Negative side of EI:

  • Emotions are complex, and they cannot always be managed or controlled.
    • Emotional intelligence does not guarantee that one’s emotions will always work in their favour.
    • Example: Hitler speeches to play with Germans emotions
  • Emotional intelligence is not a substitute for critical thinking or problem-solving skills, and it cannot guarantee success in all situations.
  • Left wing extremism and Terror organisations manipulating innocent youth emotions and led them to fight against state.

Way Forward:

Thus, the leaders/bureaucrats who possess high levels of emotional intelligence are able to coach teams, control stress, give criticism, and work effectively with others. To improve emotional intelligence, leaders can practice self-reflection and regulate their emotions, remain motivated, show empathy, and develop social skills such as conflict resolution and effective communication.

Marine Heat Waves

Syllabus

  • Mains – GS 1 (Geography) and GS 3 (Environment)

Context: Extreme heat has plagued the Mediterranean for weeks ending with wildfires across nine countries in the region from Algeria to Greece. This increasing heat has affected the marine life as well.

About Mediterranean Sea:

  • The Mediterranean Sea is a sea connected to the Atlantic Ocean and almost completely enclosed by land:
    • on the north by Western and Southern Europe and Anatolia,
    • on the south by North Africa, and
    • On the east by the Levant.
  • The Mediterranean Sea covers an area of 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only 14 km (9 mi) wide.
  • The Mediterranean Sea encompasses a vast number of islands, some of them being of volcanic origin.
    • The two by far largest islands are Sicily and Sardinia.
  • In the extreme northeast, it is connected to the Black Sea via the Dardanelles Strait, the Sea of Marmara, and the Bosporus Strait.
  • The Mediterranean Sea is also connected to the Red Sea via the Suez Canal in the southeast.
  • 22 countries and one territory (Gibraltar – a British Overseas Territory) have coasts on the Mediterranean Sea.
  • The Mediterranean Sea offers a staggering 46,000 km (28,600 mi) long coastline and includes 15 marginal seas, such as the Balearic Sea, the Adriatic Sea, the Levantine Sea and the Ionian Sea.

About Marine heat waves (MHW):

  • A marine heatwave is defined as when seawater temperatures exceed a seasonally varying threshold (usually the 90th percentile) for at least five consecutive days. Successive heatwaves with gaps of 2 days or less are considered part of the same event.
  • Due to increased greenhouse gas emissions, extended periods of extreme warming in seas and oceans have increased in frequency by 50% in the past 10 years and are becoming more severe.
  • According to a recent forecast by an organisation Mercator Ocean International, at present, MHWs have gripped:
    • the north-east Pacific,
    • the southern hemisphere in the southern Indian Ocean and the Pacific,
    • the north-east Atlantic, tropical North Atlantic, and the Mediterranean.

Reasons for Marine Heat Waves:

  • The main cause of marine heat waves is the increase in ocean temperature due to the absorption of greenhouse gasses from the atmosphere, which leads to global warming.
  • Natural climate variability can also contribute to marine heat waves, including changes in ocean currents, weather patterns, and atmospheric circulation.
  • The other common drivers of marine heatwaves include ocean currents, which can build up areas of warm water and air-sea heat flux, or warming through the ocean surface from the atmosphere.
  • Winds can enhance or suppress the warming in a marine heatwave, and climate models like El Niño can change the likelihood of events occurring in certain regions.

Impacts of Marine Heatwaves:

  • Coral bleaching: Marine heatwaves can lead to coral bleaching, which is the loss of photosynthetic algae, called zooxanthellae, from the coral. This can ultimately lead to the death of coral.
  • Ocean acidification: Marine heatwaves can exacerbate ocean acidification, which is the increase in acidity of seawater due to the absorption of carbon dioxide from the atmosphere.
    • This can have negative impacts on marine organisms that build shells or skeletons out of calcium carbonate, such as corals and some types of plankton.
  • Harmful algal blooms: Marine heatwaves can cause harmful algal blooms, which can produce toxins that are harmful to humans and marine life.
  • Ocean circulation: Marine heatwaves can also affect ocean circulation by altering the temperature and density of ocean water, which can have implications for ocean currents and the transport of nutrients and heat around the globe.
  • Marine biodiversity: Marine heatwaves can affect the composition and abundance of marine species, leading to changes in marine biodiversity.

Benefits to some species:

  • Jellyfish bloom: Jellyfish are thriving because of higher temperatures, as well as nutrient run-off from farms and sewage.
    • Overfishing and loss of fish habitat mean the jellyfish have few or no predators.
    • When currents push the animals together, the Mediterranean turns into a crowded jellyfish hotspot.
  • Invasive species: The sea also hosts around 1,000 invasive species — the highest number in the world.
    • While this is not directly linked to climate change or rising temperatures such conditions clearly favour species introduced from warmer seas.
    • For instance, invasive Rabbitfish native to the Indo-Pacific and Rea Sea feed on seaweed and have reshaped the habitat of the eastern Mediterranean.
    • Underwater deserts have replaced dense seaweed forests.

Way Forward: Suggestive measures

  • Mitigation: Reducing greenhouse gas emissions is crucial to slow down global warming and the frequency of MHWs.
    • Governments and industries should invest in renewable energy sources, promote energy efficiency, and adopt sustainable practices to mitigate climate change.
  • Adaption: National and sub-national governments should design and implement measures to protect communities and build regional ocean resilience.
    • Examples of such measures include creating and protecting marine protected areas to act as refuges for species of coral, kelp and seagrass; and enforcing catch management or fishing restrictions to help limit economic losses linked to MHWs.
  • Nature Based Solutions: Governments must invest in nature-based solutions alongside ambitiously reducing fossil fuel-based emissions to achieve the goals agreed to under the Paris Agreement.
  • International Collaboration: Foster international collaboration and networks, such as the Marine Heatwave International Group, to share knowledge, data, and best practices in addressing MHWs on a global scale.
  • Research and Monitoring: Invest in research and monitoring programs to better understand MHWs, their impacts, and their future projections.
