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 …
The meridional overturning circulation (MOC) of the Atlantic Ocean is considered to be one of the most important components of the climate system. This is because its warm surface currents, such as the Gulf Stream, redistribute huge amounts of energy from tropical to high latitudes and influence regional weather and …
GANDHINAGAR: In a major step towards putting the Kalpasar project on fast track, the Gujarat government last week commissioned a bathymetric and geotechnical study of the entire oceanic space in order to ascertain its different layers, including fault-lines. The study, to be completed by January 2012, will closely study tidal …
Emissions of a broad range of greenhouse gases of varying lifetimes contribute to global climate change. Carbon dioxide displays exceptional persistence that renders its warming nearly irreversible for more than 1,000 y. Here we show that the warming due to non-CO2 greenhouse gases, although not irreversible, persists notably longer than …
Floating Windmills Will Harness Energy Where Winds Are Strongest Danny Fortson Agroup of companies has come up with a radical proposal that it claims will open up thousands of kilometres of coastline to zero-carbon power: floating windmills. Project Deepwater was launched last year by firms including BAE Systems, the defence …
Phytoplankton biomass and productivity have been continuously monitored from ocean color satellites for over a decade. Yet, the most widely used empirical approach for estimating chlorophyll a (Chl) from satellites can be in error by a factor of 5 or more. Such variability is due to differences in absorption and …
Coral reefs worldwide are in decline. Much of the mortality can be attributed to coral bleaching (loss of the coral's intracellular photosynthetic algal symbiont) associated with global warming. How corals will respond to increasing oceanic temperatures has been an area of extensive study and debate. Recovery after a bleaching event …
The need to have quantitative means of probing anticipated rainfall is essential and inevitable for the purposes of planning and policy formulation. This paper attempts to present some results of an ongoing experiment on empirical prediction of seasonal rainfall in Nigeria. Rainfall in Nigeria is characterized by both latitudinal and …
The World Meteorological Organization (WMO) and the Convention on Biological Diversity (CBD) have released a report titled "Climate, Carbon and Coral Reefs," outlining the threat to coral reefs caused by climate change and subsequent coral bleaching, as well as by ocean acidification. The report outlines the role of meteorological services …
Polymetallic nodules found on the deep seafloor (>4000 m water depth) have been recognized as an alternative source for certain metals, when land deposits get exhausted. Spread over millions of square kilometres on the seafloor of all the oceans, these deposits contain as much as 40% of combined metals (Mn …
Washington: Moses might not have parted the Red Sea, but a strong east wind that blew through the night could have pushed the waters back in the way described in biblical writings and the Quran, US researchers reported. Computer simulations, part of a larger study on how winds affect water, …
Climate change is often associated with an increase in the frequency of extreme weather events, such as heat waves or intense precipitation. Here, however, downscaled climate model simulations have been used to show that the frequency of North Atlantic polar lows
Viju B and Simit Bhagat | TNN Mumbai: Environmentalists have asked the government to find ways to curb the impact of oil spill that has been systemically destroying the beaches of Alibaug and Mumbai.
The sea evokes awe in most of us. It inspires some to poetry and literature. This artistic imagination is showcased in an exhibition at Washington’s Folger Shakespeare Library. Its subtitle, The Ocean in the English Imagination, 1550- 1750, might suggest a lulling drone of academic solemnity, but its main title, …
When three Chinese scientists plunged to the bottom of the South China Sea in a tiny submarine early this summer, they did more than simply plant their nation
It will assess ocean current patterns and will be completed by middle of 2011 SCIENTIFIC SPIRIT:Rajendra Kumar Pachauri, Director-General TERI, laying the foundation stone for MARG Science Park near Marakkanam on Thursday. G.R.K. Reddy, chairman and managing director of MARG Group, is in the picture. CHENNAI: A year-long Environmental Impact …
At the end of the last ice age, rising atmospheric CO2 levels coincided with a decline in radiocarbon activity, suggesting the release of highly radiocarbon-depleted CO2 from the deep ocean to the atmosphere. These authors present radiocarbon records of surface and intermediate-depth waters from two sediment cores and find an …
Humans have reduced the abundance of many large marine vertebrates, including whales, large fish, and sharks, to only a small percentage of their pre-exploitation levels. Industrial fishing and whaling also tended to preferentially harvest the largest species and largest individuals within a population. We consider the consequences of removing these …
