A thick layer of smog covered parts of Mumbai and Delhi on Friday, as slow wind speeds and winter weather trapped pollutants close to the ground, pushing air quality levels into the ‘poor’ and ‘very poor’ categories. In Mumbai, the Central Pollution Control Board (CPCB) recorded an Air Quality Index (AQI) of 214 at Bandra Reclamation and 222 in Bandra Kurla Complex around 9 a.m., both falling under the ‘poor’ category. Other neighbourhoods reported similar trends, with Borivali East registering an AQI of 150 and Chembur at 132. Delhi saw an even sharper decline in air quality. The city’s overall AQI touched 312 on Friday morning, rising from Thursday’s 271. Several monitoring stations, including Anand Vihar and Ashok Vihar, recorded AQI levels above 300, placing them firmly in the ‘v...

Hurricane Melissa has caused extensive devastation across western Jamaica, leaving behind nearly 5 million tonnes of debris that is slowing critical relief and recovery operations. The hurricane, one of the most powerful to strike the Atlantic region in recent years, has resulted in widespread destruction of homes, roads, and essential services. According to the United Nations Development Programme (UNDP), the debris left behind is enough to fill approximately 480,000 truckloads. UNDP representative Kishan Khoday said the cleanup must be accelerated to prevent prolonged hardship. He warned that every delay in clearing roads and public spaces means extended power outages, stalled aid deliveries, and continued economic losses for communities already under severe distress. The storm has...

It offers immediate access to laboratory test protocols, specimen collection guidelines, test turnaround times, and diagnostic interpretation notes, allowing faster and more informed decision-making at the point of care. According to the NHLS, the app is especially valuable in situations where pr...

Belem, Brazil: Authorities are on heightened alert after a threat was issued against a power substation in Belem, the host city for the upcoming COP30 United Nations climate summit. The reported threat is believed to be linked to the Comando Vermelho, one of Brazil’s most powerful criminal gangs, and comes shortly after a major police operation in Rio de Janeiro that resulted in 121 deaths. Threat issued after police raids The Mines and Energy Ministry received information on October 30, just two days after the large-scale police operation in Rio. The operators of the Belem-Marituba substation, Verene Energia, said the message demanded that construction work be halted and daily operations be suspended from 3 p.m. onwards. Possible link to gang retaliation Federal police are inv...

Belem, Brazil: World leaders gathered in the heart of the Amazon rainforest for a major United Nations climate summit, where the urgency of addressing global warming dominated discussions. UN Secretary-General Antonio Guterres delivered a strong message, warning that continued dependence on fossil fuels was pushing the world closer to irreversible climate damage. Guterres criticized the influence of oil and gas interests in shaping climate policy, arguing that global inaction has already resulted in severe environmental disruptions. He urged governments to act decisively to keep global temperature rise within safe limits. Brazil’s President, Luiz Inacio Lula da Silva, appealed to nations to uphold past climate commitments and protect the Amazon, which plays a key role in regulating t...

A new study has raised serious concerns about the future of some of the world’s most cherished luxury crops. Coffee, chocolate, and wine products enjoyed globally and central to many farming economies are increasingly threatened by rapidly shifting climate conditions. Researchers warn that even with new climate-cooling strategies, many of these crops may struggle to survive in their traditional growing regions. What the study found A research team from Colorado State University examined 18 major crop-producing regions across Western Europe, northern South America, and West Africa, projecting conditions between 2036 and 2045. Their focus was on whether a proposed climate intervention method, known as stratospheric aerosol injection (SAI), could help preserve suitable growing condi...

Gerukamukh, a quiet village on the Assam–Arunachal Pradesh border, is emerging as a key site in India’s energy transition. Here, on the banks of the Subansiri river, work is nearing completion on the Subansiri Lower Hydroelectric Project (SLHEP) the country’s largest under-construction hydropower project with a capacity of 2,000 MW. Major milestone after years of delay Half of the project structures, including the main dam and water conductor systems, lie upstream in Arunachal Pradesh. The other half, including the power house where electricity will be generated, is located in Assam’s Gerukamukh.
