Wobbly Earth Shifts in Molten Core Could Be Altering Day-Length Fluctuations

Breaking News, Environment, Learning & Developments

Earth's day-night cycle, defined as a precise 24-hour period, serves as the cornerstone of our daily routines. Yet, the reality of our planet's rotation is far from precise. As Earth hurtles around the Sun at a staggering 107,000 kilometers per hour (67,000 miles per hour), its wobbly, molten interior and interactions with the Moon introduce subtle irregularities to the planet's rotation. Decoding Earth's Wobbly Spin While many short-term fluctuations in Earth's day-length have well-known causes such as the Moon's gravitational pull and shifting water volumes geophysicists have observed minute variations over millennial timescales that remain enigmatic. These fluctuations, amounting to just 3 to 4 milliseconds every thousand years, have perplexed scientists for decades. A team of ...

Kolkata’s Air Pollution Woes: Is It the Next Delhi?

Breaking News, Climate Actions, Disasters, Environment

KOLKATA – As Delhi grapples with hazardous air pollution levels, Kolkata’s deteriorating air quality raises pressing questions about its future. Though Kolkata has not reached Delhi’s alarming Air Quality Index (AQI) highs, its current AQI of 150-200 (classified as "very unhealthy") highlights an escalating problem that demands immediate attention. With Delhi’s AQI peaking at an unprecedented 700 in some areas this year, emergency measures were implemented, including school closures and a return to masks reminiscent of the COVID-19 era. The crisis has underscored the urgent need for sustained action not just in the capital but across the nation. Kolkata, while geographically distinct, faces its own set of challenges that could lead to a similar scenario if not addressed proactively. ...

NASA Juno Uncovers the Secret of Io Volcanic Activity

Breaking News, Environment, Learning & Developments

NASA’s Juno mission has resolved a 44-year-old mystery about Io, Jupiter’s fiery moon. New research reveals that each of Io’s volcanoes is powered by its own localized magma chamber, dismissing the long-held theory of a global magma ocean beneath the moon's surface. The groundbreaking discovery was unveiled in a study published in Nature on December 12 and was also a highlight of the American Geophysical Union’s annual meeting in Washington. The finding deepens our understanding of Io, the most volcanically active body in the solar system, and its role in planetary science. Io, about the size of Earth’s Moon, hosts over 400 volcanoes that constantly spew lava and gas. While the moon was discovered by Galileo Galilei in 1610, its volcanic activity wasn’t observed until 1979, when NASA...

World Largest One Trillion Iceberg Melt Down After Decades of Stillness

Breaking News, Climate Actions, Disasters, Environment

The world’s largest and oldest iceberg, A23a, has broken free after decades of being grounded on the seabed near Antarctica. This colossal "mega-berg," weighing over a trillion tonnes and spanning an area twice the size of Greater London, is now drifting into the Southern Ocean. A23a was calved from Antarctica’s Filchner Ice Shelf in 1986, marking the beginning of its extraordinary journey. For over 30 years, it remained grounded on the seabed of the Weddell Sea. In 2020, it began to shift northward, but its progress was slowed by a Taylor Column, an oceanographic phenomenon that kept it spinning in one spot for months. Dr. Andrew Meijers, an oceanographer at the British Antarctic Survey, remarked, “It’s exciting to see A23a on the move again after periods of being stuck. We are curi...

Delhi Air Quality Hits ‘Severe Plus’ as GRAP Stage 4 Restrictions Return

Breaking News, Disasters, Environment

Delhi air quality deteriorated further on Wednesday, with the Air Quality Index (AQI) surpassing 440, marking another day in the ‘severe’ category. By 7 am, several monitoring stations reported AQI levels above 450, pushing parts of the city into the ‘severe-plus’ category. Areas like Anand Vihar, Nehru Nagar, and Jahangirpuri recorded AQI levels near 480, signifying hazardous air. The Central Pollution Control Board (CPCB) defines AQI above 450 as “severe-plus,” with serious health implications for all age groups. In response, authorities have reimposed Stage 4 of the Graded Response Action Plan (GRAP), banning construction, restricting diesel trucks, and recommending work-from-home for 50% of employees. Public health experts warn breathing Delhi’s air is akin to smoking 10 cigarett...

Delhi Chokes Again AQI Hits ‘Severe’ Levels Amid Winter Smog

Breaking News, Disasters, Environment

Delhi’s air quality plummeted further on Tuesday, December 17, 2024, breaching the hazardous threshold with the Air Quality Index (AQI) soaring to 421 at 7 a.m., according to the Commission for Air Quality Management (CAQM). Key areas like Anand Vihar, Ashok Vihar, Bawana, Jahangirpuri, and Alipur reported AQI levels ranging from 400 to 470, marking a dire escalation in the city's ongoing battle with toxic air. The Central Pollution Control Board (CPCB) classified Delhi’s air as “Very Poor,” though localized areas ventured into the more alarming “Severe” zone. Such levels pose significant health risks, particularly for vulnerable groups such as children, the elderly, and those with respiratory conditions. Adding to the city’s challenges, the India Meteorological Department (IMD) reco...

Study Warns Claims that Pet Cats May Trigger New Bird Flu Pandemic

Breaking News, Disasters, Environment, Learning & Developments

A recent study has raised alarms about pet cats potentially becoming carriers of the deadly H5N1 bird flu virus, which has devastated poultry farms in the U.S. over the past two and a half years. Published in the journal Taylor and Francis, the study warns that just one or two mutations in cats could allow the virus to jump to humans, posing significant public health risks. Bird Flu’s Hidden Threat H5N1, responsible for the deaths of over 100 million birds, has remained a limited threat to humans due to its difficulty in transmitting between people. However, scientists fear cats common household pets could serve as a bridge for the virus to evolve and spread more easily. The warning comes after the deaths of 10 cats in South Dakota earlier this year. Researchers found that the cat...

Amazon Fires Intensify as Groundwater Depletion El Niño Fuel Catastrophic Events

Breaking News, Climate Actions, Disasters, Environment

A groundbreaking study has demonstrated a clear link between climatic phenomena and the rising propensity for fires in the Amazon rainforest. Researchers have identified compromised groundwater storage, exacerbated by El Niño-driven droughts, as a critical factor in escalating fire risks. The findings, backed by satellite data and fire reports, could pave the way for more effective prevention strategies. Role of Groundwater and El Niño in Amazon Fires The study highlights that regions with depleted groundwater storage are at greater risk of fires during extreme droughts. Researchers observed that during El Niño events, prolonged dry conditions impact three key water reservoirs: topsoil, the tree root zone, and groundwater, with groundwater being the slowest to recover. El Niño, chara...
