Future of Hydropower in a Changing Climate Challenges, Innovations, and Strategies for Sustainability

Breaking News, Environment, Opinions

The history of hydrocarbons traces back millennia, with early civilizations recognizing their natural occurrence and limited applications. Ancient cultures utilized natural tar and bitumen for waterproofing and adhesive purposes, while early records suggest hydrocarbons were employed for lighting and heating. However, it was during the Industrial Revolution that hydrocarbons gained prominence, particularly with the emergence of coal as a primary fuel source. The mid-19th century witnessed a pivotal shift with the discovery of oil deposits, leading to the rapid expansion of the petroleum industry and the development of refining technologies. Subsequently, the widespread adoption of petroleum-based fuels, such as gasoline and diesel, during the early 20th century fueled industrialization ...

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...

Surprisingly Improved Air Quality of Delhi in April 2024

Breaking News, Environment

Delhi experienced a notable improvement in air quality during April 2024, recording the maximum number of 'Good to Moderate' air quality days in comparison to the last six years, with the exception of the lockdown year 2020 due to COVID-19. This improvement can be attributed to favorable meteorological conditions and the concerted efforts of the Commission for Air Quality Management in NCR and Adjoining Areas (CAQM) along with various stakeholders to control air pollution in the National Capital Region (NCR). Key Highlights Number of Good to Moderate Air Quality Days: Delhi witnessed 23 days with 'Good to Moderate' air quality in April 2024, compared to 17 days in 2023, 0 in 2022, 18 in 2021, 30 in 2020 (during the lockdown period), 12 in 2019, and 8 in 2018. Control of Poor to Se...

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

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 ...

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

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...

Moon’s Influence on Coral Reef Sounds Reveals Ecosystem Activity: Study says

Breaking News, Climate Actions, Environment

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...
