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 …
VELLORE: Calling on engineers to come up with technologies which will aid in the development of a fleet of robots for underwater exploration, Mohd Rizal Arshad, Director of the Underwater Robotics Research Group, at Universiti Sains, Malaysia, on Tuesday said engineering must act as a tool for oceanographers to study …
This policy brief was prepared by the UN Department of Economic and Social Affairs (UNDESA), Division for Sustainable Development, and reviews the topic of ocean acidification and current UN actors that are considering oceans issues. It also presents policy options related to: international action on mitigating carbon dioxide emissions; information …
The surface ocean plays a critical role in the global carbon cycle, absorbing approximately one quarter of the carbon dioxide emitted to the atmosphere from the burning of fossil fuels, deforestation, and other human activities. As more and more anthropogenic CO2 has been emitted into the atmosphere, the ocean has …
So far, the oceans have protected us from the full force of anthropogenic climate change. The global ocean is the largest active carbon sink on Earth, and since the industrial revolution it has soaked up around one third of all anthropogenic carbon dioxide emissions.
With water level falling by a metre a year and no measures has been taken yet to reverse the decline, the Dead Sea may soon shrink to a pond or even dry out completely by 2050. According to officials, the political strife in West Asia has been undermining measures to …
In a clear sign of the growing faith of the US in Indian space programmes, two top US agencies - the National Aeronautics and Space Administration (NASA) and the National Oceanic and Atmospheric Administration (NOAA) - signed a letter of intent (LoI) on Wednesday to obtain data from the Oceansat-2 …
The ocean takes up 20 to 35 per cent of anthropogenic CO2 emissions, but uncertainties remain as to the distribution of this CO2 in the ocean, its rate of uptake over the industrial era, and the relative roles of the ocean and terrestrial biosphere in anthropogenic CO2 sequestration. An observationally …
In the tortured history of climate-change negotiations, enlightened thinking has translated into positive action all too rarely. But governments have recently seen the light on a crucial issue: they have recognized the vital role that intact natural ecosystems have in limiting the build-up of atmospheric greenhouse gases.
Efforts to control climate change require the stabilization of atmospheric CO2 concentrations. This can only be achieved through a drastic reduction of global CO2 emissions. Yet fossil fuel emissions increased by 29% between 2000 and 2008, in conjunction with increased contributions from emerging economies, from the production and international trade …
The study of stable oxygen isotope ratios (delta18O) of Precambrian cherts suggests that ocean temperatures during the Archaean era (about 3.5 billion years ago) were between 55
This article reviews the various available methodologies to estimate submarine groundwater discharge (SGD) and demonstrates the utility of radon with a case study. An attempt has been made to identify the existence of submarine groundwater discharge (SGD)and semi-quantitatively estimate its rate in the coastal area of Vizhinjam, Thiruvananthapuram, Kerala.
This document provides an overview of the interactions between the ocean and climate and describes the impacts of climate change on the marine ecosystems and the goods and services they provide human society. Further, it outlines a set of recommendations for marine-related mitigation and adaptation policy and implementation actions. The …
MUMBAI: The Mumbai coast guard's pollution response team (west) is set to purchase three modern pollution control vehicles (PCVs) to ensure a cleaner sea off the western shores. Induction of PCVs in the Coast Guard's fleet, along with other modern equipment to control oil spills and pollution, will be complete …
OCEANS ARE DYING: Ocean deserts where very few organisms can survive due to scanty supply of nutrients are expanding. These vast stretches of barren sea could affect the marine food chain, and in turn the global fish stock, said scientists from North America who analyzed satellite data between 1997 and …
THE INTERNATIONAL LAW OF THE SEA by O P Sharma, Oxford University Press, Rs 795 The law of the sea has undergone more changes in the last 60 years than in the past 100. This book deals with some of the changes. The author analyzes concepts like ocean governance, the …
