The World Meteorological Organization’s State of the Climate in Asia 2024 report warns that the region is warming nearly twice as fast as the global average, driving more extreme weather and posing serious threats to lives, ecosystems, and economies. In 2024, Asia experienced its warmest or second warmest year on …
As the land of the Thunder Dragon is all set to host the seventh edition of the Mountain Echoes Literary festival, global issues, including climate change and women's voices, will top the agenda. The three-day festival from Friday is an initiative of the India Bhutan Foundation, in association with Siyahi, …
"This is the first discovery of its kind in the Indian Ocean that has the potential to be producible," USGS said in a statement. A large natural gas discovery has been made in the Indian Ocean following a joint expedition by India and the U.S., opening up a new resource …
Tropical cyclones play an important role in modifying the tropopause structure and dynamics as well as stratosphere–troposphere exchange (STE) processes in the upper troposphere and lower stratosphere (UTLS) region. In the present study, the impact of cyclones that occurred over the north Indian Ocean during 2007–2013 on the STE processes …
If researchers are right, a quake would probably turn urban areas in eastern India "into ruins," according to a sesismologist. A huge earthquake that can turn urban areas in eastern India into “ruins” may be building beneath Bangladesh, a new study has warned. The study was published in journal Nature …
A cyclogenesis index (CSGP) is introduced and its variations have been evaluated for the period 1979 to 2008. It is found that CSGP is able to distinguish different categories of storms over North Indian Ocean. The relative roles of contributing parameters are analyzed to study the influence of CGSP with …
The Indo-Pacific warm pool (IPWP) has warmed and grown substantially during the past century. The IPWP is Earth’s largest region of warm sea surface temperatures (SSTs), has the highest rainfall, and is fundamental to global atmospheric circulation and hydrological cycle. The region has also experienced the world’s highest rates of …
Lightning is one of the major threats to multimegawatt wind turbines and a concern for modern aircraft due to the use of lightweight composite materials. Both wind turbines and aircraft can initiate lightning, and very favorable conditions for lightning initiation occur in winter thunderstorms. Moreover, winter thunderstorms are characterized by …
EI Nino refers to warming of the eastern tropical Pacific, whichdisrupts the local climate and has a wider effect on general weatherpatterns. The opposite of this term is La-Nina. The La Nina implies tocooling of the eastern tropical Pacific, occurring in certain years. “La Nina” also casts larger effects on …
The Indian summer monsoon rainfall had a threedecade long alternate dry and wet epochs during about 150 years from 1840 to 1989. The dry epochs resulted in frequent drought monsoons affecting agriculture, power generation and the overall economy of the country. A high percentage of severe cyclones in the Bay …
The longest global coral bleaching event in history is now devastating reefs in the crystal clear waters of the Maldives, with images released exclusively to the Guardian powerfully illustrating the extent of the damage there. Photographed by the XL Catlin Seaview Survey, the images captured the event in May as …
Fish biomass is a primary driver of coral reef ecosystem services and has high sensitivity to human disturbances, particularly fishing. Estimates of fish biomass, their spatial distribution, and recovery potential are important for evaluating reef status and crucial for setting management targets. Here we modeled fish biomass estimates across all …
Oxygen-poor waters occupy large volumes of the intermediate-depth eastern tropical oceans. Oxygen-poor conditions have far-reaching impacts on ecosystems because important mobile microorganisms avoid or cannot survive in hypoxic zones. Climate models predict declines in oceanic dissolved oxygen produced by global warming. The researchers constructed a 50-year time series of dissolved-oxygen …
The global carbon cycle is highly sensitive to climate-driven fluctuations of precipitation, especially in the Southern Hemisphere. This was clearly manifested by a 20% increase of the global terrestrial C sink in 2011 during the strongest sustained La Niña since 1917. However, inconsistencies exist between El Niño/La Niña (ENSO) cycles …
PANAJI: Rapidly decreasing presence of marine phytoplankton, a micro-algae consumed by small fish and responsible for reducing carbon dioxide in sea water, in the western Indian Ocean due to global warming may reduce the oceanic region to an ecological desert, scientists have warned. A joint study conducted by scientists at …
Countries export much of the harm created by their greenhouse gas (GHG) emissions because the Earth’s atmosphere intermixes globally. Yet, the extent to which this leads to inequity between GHG emitters and those impacted by the resulting climate change depends on the distribution of climate vulnerability. Here, we determine empirically …
This study unravels the physical link between the weakening of the monsoon circulation and the decreasing trend in the frequency of monsoon depressions over the Bay of Bengal. Based on the analysis of the terms of Genesis Potential Index, an empirical index to quantify the relative contribution of large scale …
Marine plastic pollution is an ever-increasing problem that demands immediate mitigation and reduction plans. Here, a model based on satellite-tracked buoy observations and scaled to a large data set of observations on microplastic from surface trawls was used to simulate the transport of plastics floating on the ocean surface from …
Precipitation associated with the South Asian summer monsoon has decreased by approximately 7% since 1950, but the reasons for this are unclear. Now research suggests that changes in land-cover patterns and increased emissions from human activities have contributed to this weakening, which is expected to continue in the coming decades.
Expedition will have 20 countries and 40 ships participating; countries will collate and analyse data to study different climatic challenges and changes PANJIM: Almost 50 years after the first International Indian Ocean Expedition was conducted, National Institute of Oceanography (NIO) is set to launch the second expedition to study the …
Determining the links between the behavioural and population responses of wild species to environmental variations is critical for understanding the impact of climate variability on ecosystems. Using long-term data sets, we show how large-scale climatic anomalies in the Southern Hemisphere affect the foraging behaviour and population dynamics of a key …
