Current Affairs Quiz - November, 2024

Notes:
The first Climate and Health Africa Conference (CHAC 2024) is taking place in Harare, Zimbabwe, from October 29-31. This conference brings African nations into the global discussion on climate change and its health impacts, where Africa faces high burdens of climate-sensitive diseases. More than 400 participants, including government officials, health and climate experts, and researchers, attended the conference. It focuses on sharing innovations, best practices, and solutions to build climate resilience in health.

Notes:
NTPC has created a catalyst to produce methanol from gases emitted by fossil-fired power plants. This development was achieved in collaboration with the Indian Institute of Petroleum. CO2 mitigation is a major challenge for fossil-fired power plants. The focus is on capturing CO2 from flue gas and converting it into valuable fuels and chemicals. The catalyst produces methanol with a purity of over 99%.

Notes:
NASA’s Landsat 8 satellite captured images of ‘sea smoke’ rising from Antarctica’s Pine Island Glacier, a phenomenon where frigid air meets warm water, creating fog-like plumes. This rare atmospheric event highlights the glacier’s vulnerability and the impact of strong winds on polar ice sheets. Sea smoke forms when cold air cools and condenses over open waters, resulting in ghostly ice crystal plumes that can influence ice mass balance. Pine Island Glacier is known for its rapid retreat and significant role in ice flow dynamics.

Notes:
The International Day to End Impunity for Crimes against Journalists (IDEI) is observed on November 2, recognized by the United Nations to protect journalists and seek justice for crimes against them. IDEI was proclaimed by the UN in Resolution A/RES/68/163, marking the 2013 killing of two French journalists in Mali. It aims to tackle violence against journalists, crucial for freedom of expression and access to information. The 2024 theme, “Safety of Journalists in Crises and Emergencies,” focuses on protecting journalists in conflict zones. Journalists in high-risk areas face violence, restricted access, and detention, creating “zones of silence.”

Notes:
Scientists have discovered a lost Mayan city in the dense Mexican jungle using LiDAR technology. LiDAR stands for Light Detection and Ranging and is a remote sensing method that uses pulsed lasers to measure distances to the Earth’s surface. It can create high-resolution 3-D models of ground elevation with vertical accuracy of up to 10 cm. The LiDAR system includes a laser, scanner, and GPS receiver. The laser fires rapidly, hitting surfaces like vegetation and buildings, with the reflected light recorded by the sensor.

Notes:
The government plans to conduct the Census in 2025, widely welcomed for its policy-shaping role since 1872. Census 2025 will include key initiatives like potential caste enumeration, pending government approval. It will also assist in electoral delimitation and help create the National Population Register (NPR). The Census captures essential demographic, economic, and socio-political trends in India. The Ministry of Home Affairs is responsible for conducting the census in India. The Office of the Registrar General and Census Commissioner of India is responsible for planning, implementing, and conceiving the census.  The Directorate of Census Operations in each state and union territory (UT) is responsible for conducting the census in their respective jurisdictions.

Notes:
The Tamil Nadu government has declared a heatwave as a State-specific disaster to provide relief and compensation for heat-related casualties. Interim actions will be taken to manage the heat, funded by the State Disaster Response Fund. A heat wave is defined as a period of abnormally high temperatures above the normal maximum. In India, heat waves usually occur from March to June and can extend into July. On average, five to six heat wave events happen annually in northern India. A heat wave is considered if temperatures reach 40°C or more in plains and 30°C or more in hilly areas. Severe heat waves are classified by greater temperature deviations or higher maximum temperatures.

Notes:
Indian botanists have discovered a new leafless orchid species, Gastrodia lohitensis, in Arunachal Pradesh’s Lohit district. This orchid thrives in bamboo thickets around Tezu, relying on nutrients from fungi in decomposing leaf litter instead of sunlight. The discovery was led by Krishna Chowlu from the Botanical Survey of India during a May 2024 expedition. Gastrodia lohitensis stands 50-110 cm tall and has unique features, including linear calli and ridges on its flower lip. It is classified as “Endangered” due to threats from local land use, emphasizing the need for habitat protection in this biodiverse area.

Notes:
Cyclone Dana brought heavy rain to Kolkata, causing chhatim trees (Alstonia scholaris) to shed their strong-smelling flowers, offering relief for allergy and asthma sufferers. It is a tropical tree in the dogbane family (Apocynaceae). Alstonia scholaris, also called blackboard tree, scholar tree, or devil’s tree, is native to the Indian subcontinent, Southeast Asia, and southern China. Known as “saptaparni” in India, it has clusters of seven leaves and blooms small, fragrant greenish-white flowers in late autumn. The tree’s bark and leaves are used in traditional medicine for respiratory, skin, and digestive issues. Its wood was once used to make blackboards, hence the name “blackboard tree.”

Notes:
Haryana’s boxer Mandeep Jangra won the World Boxing Federation’s super featherweight world title by defeating British boxer Conor McIntosh. The title match took place in the Cayman Islands. Mandeep, 31, turned professional in 2021 and trains under American boxing legend Roy Jones Junior. He won silver at the 2013 Asian Championship and the 2014 Glasgow Commonwealth Games. Mandeep received the Arjuna Award from the Indian government in 2015.
