Rising Temperatures in India’s Metro Cities Understanding the Urban Heat Island Effect

Rising Temperatures in India’s Metro Cities Understanding the Urban Heat Island Effect

Breaking News, Climate Actions, Environment
As the calendar flips to May, India's major metropolitan cities are experiencing a surge in temperatures, with Delhi, Mumbai, Chennai, and Bengaluru all recording high mercury levels. The phenomenon is not merely a seasonal shift but is closely linked to the urban heat island effect, significantly impacting urban environments. The urban heat island effect describes a situation where urban areas exhibit higher temperatures compared to their rural surroundings. This disparity arises primarily due to human activities and the infrastructure in cities, which absorb and retain heat more efficiently than natural landscapes. Causes and Effects Urban areas, with their abundance of concrete and asphalt, absorb heat during the day and release it slowly, leading to elevated temperatures, pa...
Record-Breaking April Temperatures Grip Eastern and Peninsular India Amid General Elections

Record-Breaking April Temperatures Grip Eastern and Peninsular India Amid General Elections

Breaking News, Climate Actions, Environment
As the nation remains gripped by the ongoing polling for the 2024 general elections, eastern and peninsular India has been facing an unprecedented heatwave, with temperatures soaring to record-breaking levels throughout April. Scientists attribute this scorching heat to the looming climate crisis, underscoring the urgent need for climate action. According to data from the Meteorological Department, April marked the warmest on record in eastern and northeastern India in terms of night temperatures since 1901, and the third warmest in mean temperatures. Similarly, it was the second warmest April in the peninsula in terms of maximum, minimum, and mean temperatures. The sweltering conditions have been exacerbated by factors such as El Nino and climate change, as explained by OP Sreejith,...
Indian Ocean Basin Faces Accelerated Warming, Alarming Research Predicts Dire Consequences

Indian Ocean Basin Faces Accelerated Warming, Alarming Research Predicts Dire Consequences

Breaking News, Climate Actions, Environment
A groundbreaking research paper has shed light on the alarming pace of warming in the Indian Ocean basin, projecting a rapid increase in temperatures with profound implications for global climate dynamics. Led by climate scientist Roxy Mathew Koll from the Indian Institute of Tropical Meteorology, the study warns of accelerated warming at a rate of 1.7°C-3.8°C per century from 2020 to 2100. This unprecedented rate of warming is expected to trigger a cascade of severe weather events, prolonged marine heatwaves, and extreme Indian Ocean Dipole (IOD) events, significantly influencing monsoon patterns and cyclone development. The research, utilizing observed data and simulations from the Intergovernmental Panel on Climate Change (IPCC), paints a grim picture of the future trajectory of the ...
El Niño Fades, ENSO-Neutral Conditions Expected in May

El Niño Fades, ENSO-Neutral Conditions Expected in May

Breaking News, Climate Actions
The recent observations from the Australian Bureau of Meteorology (BOM) and the Climate Prediction Center (CPC-NOAA) suggest a transition from El Niño to ENSO-neutral conditions in the tropical Pacific. Despite indications of El Niño persisting, the intensity has notably diminished since its peak in March 2024. Ocean surface temperatures in the equatorial Pacific have shown a gradual cooling trend, with negative sub-surface anomalies extending westward. Key indicators like the Nino 3.4 index, which reflects sea surface temperature anomalies, are steadily declining and are projected to reach the threshold for ENSO-neutral conditions within the next few weeks. Additionally, the Southern Oscillation Index (SOI) remains within the ENSO-neutral range, indicating a shift towards neutral co...
Drought Threatens Endangered Hippos in Botswana’s Okavango Delta

Drought Threatens Endangered Hippos in Botswana’s Okavango Delta

Breaking News, Climate Actions, Disasters
In Botswana's northern region near the vast wetlands of the Okavango Delta, herds of endangered hippos are facing a dire situation as severe drought grips the area. The dried-up Thamalakane River, exacerbated by the El Nino weather phenomenon, has left these magnificent creatures stranded in dried-up ponds, raising concerns about their survival. Conservation authorities have sounded the alarm, warning that the hippos, already endangered, are at risk of dying if immediate action is not taken. The scarcity of water has forced the animals to seek refuge in natural water reserves near the tourist town of Maun, further highlighting the severity of the situation. Lesego Moseki, spokesperson for Botswana's Department of Wildlife and National Parks (DWNP), expressed concern over the compromi...
Climate Change to Shrink Global GDP by Almost a Fifth by 2050, Study Warns

Climate Change to Shrink Global GDP by Almost a Fifth by 2050, Study Warns

Breaking News, Climate Actions, Environment
In a stark warning, researchers revealed on Wednesday that climate change caused by carbon dioxide emissions already present in the atmosphere will lead to a substantial contraction of global GDP by 2050, amounting to nearly US$38 trillion, or almost a fifth of the total. Published in the journal Nature, the study underscores the urgent need for aggressive carbon emission reduction efforts to mitigate the economic fallout. Even under the most aggressive emission reduction scenarios, the researchers caution that significant economic losses are inevitable. The study predicts that economic repercussions from climate change could escalate to tens of trillions of dollars annually by 2100 if global warming exceeds two degrees Celsius above pre-industrial levels. With Earth's average surfac...
Antarctic Ice Shelf Reveals Daily Movement Triggered by Elastic Waves from Whillans Ice Stream

Antarctic Ice Shelf Reveals Daily Movement Triggered by Elastic Waves from Whillans Ice Stream

Breaking News, Climate Actions, Environment
In a fascinating revelation, researchers studying the Ross Ice Shelf in Antarctica have uncovered a phenomenon where elastic waves cause the entire sheet to lurch forward once or twice a day. This unexpected discovery sheds light on the dynamic nature of ice shelves and their response to changing environmental conditions. The Ross Ice Shelf, the largest in Antarctica and roughly the size of France, experiences these significant movements triggered by the Whillans Ice Stream, a fast-flowing belt of ice in the West Antarctic Ice Sheet. Geophysicist Doug Wiens from Washington University in St. Louis explains that the entire shelf suddenly moves about 6 to 8 centimeters (2.4 to 3.1 inches) due to a slip on the ice stream that flows into it. These slip events, akin to movements along faul...

Water Crisis Looms as Rivers Run Dry and Reservoirs Dwindle Across India

Water Crisis Looms as Rivers Run Dry and Reservoirs Dwindle Across India

Breaking News, Climate Actions
An alarming water crisis is unfolding across India as rivers run dry and reservoirs reach critically low levels. According to data released by the Central Water Commission (CWC), at least 13 east-flowing rivers between Mahanadi and Pennar currently have no water. These rivers, including Rushikulya, Bahuda, and Vamsadhara, play a crucial role in supplying water for irrigation and domestic consumption in Andhra Pradesh, Telangana, and Odisha. The storage in the basin has witnessed a continuous decline, with the current storage standing at zero. Last year, the storage was 32.28 per cent of the basin's capacity, highlighting the severity of the current situation. Furthermore, Andhra Pradesh and Telangana have experienced large rainfall deficits since March 1, exacerbating the water scarcity...

A recent study has shed light on how the Moon's movements influence the sounds emanating from coral reefs, providing valuable insights into ecosystem activity. Researchers discovered that as the Moon rises and sets, the soundscape of coral reefs undergoes rapid changes, indicating shifts in ecosystem interactions. Conducted by scientists from the Naval Undersea Warfare Center (NUWC) and the Advanced Research Projects Agency – Energy (ARPA-E) in the US, the study monitored three different coral reef sites off the west coast of Hawaii. Using hydrophones, they captured one-minute snapshots of the underwater soundscape at regular intervals over two years. The findings revealed that high-frequency pulse train sounds from fish increased during moonlit hours, while low-frequency fish vocali...
