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...

Breaking News, Climate Actions, Idea & Innovations
As climate change intensifies heat and drought conditions worldwide, the cultivation of common beans a staple food for millions is becoming increasingly challenging. Scientists are turning to the tepary bean, a desert-native legume, to develop more resilient bean varieties that can thrive under extreme conditions. The tepary bean, native to the Sonoran Desert, is uniquely adapted to hot and dry environments. “They are able to grow under drought and high heat conditions,” says Carlos Urrea, a dry edible bean breeding specialist at the University of Nebraska. Urrea and his team are working to harness the drought and heat tolerance of tepary beans by identifying and transferring their resilient genes into common beans. They’re also integrating disease resistance traits, creating hybrid ...

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...

Breaking News, Climate Actions, Environment
The India Meteorological Department (IMD) has forecasted the return of rainfall to Chennai and its suburbs by the middle of next week, as another low-pressure area over the Bay of Bengal is expected to approach the Tamil Nadu coast. This system is likely to trigger widespread rain across several parts of the state. The IMD has issued a yellow alert for Chennai and surrounding areas on Saturday, predicting light to moderate rain. The skies are expected to remain partly cloudy during the day, with similar weather conditions continuing on Sunday. The intensity of rainfall is likely to increase from December 16, culminating in heavy rainfall for districts like Chengalpet on December 17. On December 18, as many as 12 districts, including Chengalpet and Kancheepuram, are expected to receive h...
Greenland Experiences One of the Largest Documented Glacial Lake Outburst Floods

Greenland Experiences One of the Largest Documented Glacial Lake Outburst Floods

Breaking News, Climate Actions, Disasters, Environment
A massive glacial lake outburst flood, among the largest ever recorded, has been documented in East Greenland, releasing over 3,000 billion litres of meltwater. The event, which occurred between September 23 and October 11, was caused by the sudden release of water from Catalina Lake into the Scoresby Sound fjord, as reported by researchers at the University of Copenhagen's Niels Bohr Institute. Notably, this marks the first time such a phenomenon has been observed in real-time. The flood was triggered when meltwater from Catalina Lake, held back by the Edward Bailey Glacier for over 20 years, carved a 25-kilometre-long tunnel beneath the glacier. This process caused the lake’s water level to plummet by 154 metres. Researchers equated the released volume of water to three times Denmark'...

CHENNAI: With the northeast monsoon in full swing, Tamil Nadu is bracing for another bout of heavy rains. The Regional Meteorological Centre (RMC), Chennai, has predicted that a fresh low-pressure area will form over the Andaman Sea by Sunday, likely bringing intense rainfall back to the coastal and delta regions from December 16. On Thursday, vehicles waded through waterlogged roads near Thirumangalam Metro Station, as heavy rains continued to lash parts of Chennai and surrounding areas. However, meteorologists predict that the current weather system, a well-marked low-pressure area, will weaken by Saturday as it moves toward south Tamil Nadu and the Western Ghats. The RMC has issued an orange alert for Cuddalore, Mayiladuthurai, and Karaikal for Tuesday. Additionally, six districts...
La Niña Fails to Arrive Weather Models Miss the Mark

La Niña Fails to Arrive Weather Models Miss the Mark

Breaking News, Climate Actions, Environment
BENGALURU: As 2024 edges closer to its end it is on track to become the warmest year ever recorded, surpassing 2016. Among the key factors driving this record-breaking warmth is the unexpected absence of La Niña, a climatic phenomenon that global weather models had predicted to emerge earlier this year. Despite repeated forecasts, La Niña has failed to materialize, leaving experts scrambling to understand what went wrong. La Niña, a cooling phase of the El Niño Southern Oscillation (ENSO), typically brings colder sea surface temperatures in the central and eastern Pacific Ocean, stronger trade winds, and increased rainfall in regions like India. This phase is part of a larger cycle that includes El Niño, a warming phase, and the neutral phase, characterized by average sea surface temper...

Antarctic ‘Plastisphere’ A New Ecosystem with Hidden Dangers Surprisingly

Breaking News, Climate Actions, Environment, Fact Check
Antarctica, often considered the last pristine frontier, is no longer untouched by human activity and its environmental consequences. Plastic pollution, a hallmark of human impact, has given rise to a unique ecological phenomenon: the plastisphere—microbial communities colonizing plastic debris in the ocean. While offering intriguing scientific insights, this ecosystem poses significant threats to marine life and global ecological balance. When plastic enters the ocean, it provides surfaces for microbial communities to colonize rapidly, forming biofilms. This collection of organisms known as the plastisphere evolves through ecological succession into a complex network of microbes. These communities can carry harmful pathogens, such as Vibrio spp. and antibiotic-resistant bacteria, sprea...
