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 …
THREE BRITISH explorers have set out on a 90-day skiing expedition to the North Pole, measuring sea ice thickness the whole way to find out exactly how fast it is disappearing, according to the Catlin Arctic Survey. The data gathered will complement satellite and submarine observations and help ice modelling …
The marine environment is one of the most fascinating realm. Due to the physical and chemical conditions of the marine environment, almost every class of marine organism exhibits variety of molecules with unique structural features, which are not found in terrestrial natural products. Today researchers have isolated approximately 11,000 marine-derived …
chemical sciences Sugars preserve organs longer Growth of ice crystals during organ preservation at low temperatures leaves them unfit for transplantation. Several carbohydrates have the ability to prevent the growth of ice crystals. This ability correlates with the hydration number which is the number of water molecules bound to one …
The asynchronous relationship between millennial-scale temperature changes over Greenland and Antarctica during the last glacial period has led to the notion of a bipolar seesaw which acts to redistribute heat depending on the state of meridional overturning circulation within the Atlantic Ocean. Here we present new records from the South …
The bipolar see-saw hypothesis provides an explanation for why temperature shifts in the two hemispheres were out of phase at certain times. The hypothesis has now passed a test of one of its predictions.
The Atlantic meridional overturning circulation (AMOC) transports warm salty surface waters to high latitudes, where they cool, sink and return southwards at depth. Through its attendant meridional heat transport, the AMOC helps maintain a warm northwestern European climate, and acts as a control on the global climate. Past climate fluctuations …
Published: February 2, 2009 A leading idea to fight global climate change is to permanently remove some of the carbon dioxide building up in the atmosphere. Here
This new UNEP report focuses on East Asia's economically viable coastal habitats and ecosystems under threat from pollution, alien invasive species and other factors. Suggests a systematic and integrated approach to managing coastal & oceanic issues and economic incentives to encourage private sector involvement in environmental protection efforts. The economic …
Amit Bhattacharya | TNN New Delhi: Ending days of suspense and anxiety for the Indo-German team of scientists sailing in the cold and desolate waters off Antarctica, the German government on Monday gave the go-ahead to a controversial ocean-seeding experiment that experts say could lead to a way of fighting …
Special Correspondent THIRUVANANTHAPURAM: What does global warming portend for the monsoon that sweeps over India during the four-month period from June to September sustaining life in the subcontinent? Discouraging signals have already started becoming visible, according to the former Director of India Meteorological Department (IMD) P.V. Joseph.
Roy Mathew THIRUVANTHAPURAM: The Indian Biodiversity Forum has protested against the involvement of the National Institute of Oceanography (NIO) in the expedition to fertilise sea near Antarctica with iron sulphate. The NIO is conducting the operation in collaboration with the Alfred Wegener Institute of Germany as part of a project …
For while the tired waves, vainly breaking, Seem here no painful inch to gain, Far back through creeks and inlets making Comes silent, flooding in, the main.
This publication is targeted at the general public to highlight an important but often overlooked issue, and to serve as a source of information and inspiration. The material presented in this publication is based on a large volume of work by many institutions and scientists around the world researching marine …
life sciences It is the small ones Smaller mosquitoes are better at transmitting diseases than larger ones. Researchers in the US fed mosquitoes blood contaminated with dengue virus and tested them for infection. Smaller-sized mosquitoes showed higher infection rates and greater potential to transmit the virus. Even a slight difference …
A team of scientists has come up with a new definition of seawater which is set to boost the accuracy of projections for oceans and climate. Oceans help regulate the planet's weather by shifting heat from the equator to the poles. Changes in salinity and temperature are major forces driving …
