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 …
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 …
The impact of the Indian and Atlantic oceans variability on El Niño–Southern-Oscillation (ENSO) phenomenon is investigated through sensitivity experiments with the SINTEX-F2 coupled model. For each experiment, we suppressed the sea surface temperature (SST) variability in either the Indian or Atlantic oceans by applying a strong nudging of the SST …
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 …
Among the tropical oceans, the western Indian Ocean hosts one of the largest concentrations of marine phytoplankton blooms in summer. Interestingly, this is also the region with the largest warming trend in sea surface temperatures in the tropics during the past century—although the contribution of such a large warming to …
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 …
PANJIM: Monsoons in the country may be in for bad news as scientists predict a significant decreasing trend in the monsoon rainfall over central India. Dr Roxy Mathew Koll, scientist at the Indian Institute of Tropical Meteorology in a recent paper published in the Nature Communications journal said that rapid …
Says El Nino weather pattern has strengthened over the last two weeks The Australian Bureau of Meteorology said the recently emerged El Niño is now the strongest such event in nearly 20 years. Tropical Pacific Ocean temperature anomalies are at the highest levels since the El Niño that occurred between …
Forty years after the ocean floor was first mapped by hand, a team of Australian researchers has created the first digital map of the entire sea floor. Made by the University of Sydney's School of Geosciences and National ICT Australia (NICTA), the map can be used to plot the planet's …
After several tsunami events with disastrous consequences around the world, coastal countries have realized the need to be prepared to minimize human mortality and damage to coastal infrastructures, livelihoods and resources. The international scientific community is striving to develop and validate methodologies for tsunami hazard and vulnerability and risk assessments. …
The Regional State of Coast Report for the western Indian Ocean (WIO) is the first comprehensive regional synthesis to provide insights into the enormous economic potential around the WIO, the consequential demand for marine ecosystem goods and services to match the increasing human population, the pace and scale of environmental …
Global climatic conditions have turbocharged the monsoon and given it the momentum to take it up to Kashmir in three to four days, a week ahead of schedule, and accelerate agricultural activity in the grain-bowl states of Punjab and Haryana on the say. Rainfall in June is almost certain to …
Washington: Rapid warming of the Indian Ocean in the past century has led to a significant decrease in summer Monsoon rainfall over the central-east and northern regions of India, a new study led by an Indian scientist said on Tuesday. An international team of researchers led by Dr Roxy Mathew …
This new study led by an Indian scientist Dr Roxy Mathew Koll, from the Indian Institute of Tropical Meteorology (IITM) Pune, points out a significant decreasing trend in the summer monsoon rainfall over the central Indian subcontinent during the past century. It suggests an important role of the rapid warming …
