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 monetary value of the world’s oceans has been estimated at US$24tn in a new report that warns that overfishing, pollution and climate change are putting an unprecedented strain upon marine ecosystems. The report, commissioned by WWF, states the asset value of oceans is $24tn and values the annual “goods …
Strong ocean currents promote the release of the potent greenhouse gas methane in the Arctic, according to new research, shedding light on how they may contribute to climate change. According to Ocean and Earth Science researchers from the University of Southampton, these currents inhibit the growth of marine bacteria that …
Anthropogenic climate change is predicted to decrease oceanic oxygen (O2) concentrations, with potentially significant effects on marine ecosystems. Geologically recent episodes of abrupt climatic warming provide opportunities to assess the effects of changing oxygenation on marine communities. Thus far, this knowledge has been largely restricted to investigations using Foraminifera, with …
European continental shelf seas have experienced intense warming over the past 30 years. In the North Sea, fish have been comprehensively monitored throughout this period and resulting data provide a unique record of changes in distribution and abundance in response to climate change. We use these data to demonstrate the …
It is one of science's enduring mysteries: what caused the worst mass extinction in Earth's history. And, no, it is not the one that wiped out the dinosaurs. Scientists said on Thursday that huge amounts of carbon dioxide spewed from colossal volcanic eruptions in Siberia may have turned the world's …
Naturally occurring climate change lowered oxygen levels in the deep ocean, decimating a broad spectrum of seafloor life that took some 1,000 years to recover, according to a study that offers a potential window into the effects of modern warming. Earth's recovery from the last glacial period, in fact, was …
Last week, we learned about the possible destabilization of the Totten Glacier of East Antarctica, which could unleash over 11 feet of sea level rise in coming centuries. And now this week brings news of another potential mega-scale perturbation. According to a new study just out in Nature Climate Change …
This paper presents key results from analysis of surface meteorological observations collected in the Northern Arabian/Persian Gulf (N Gulf; Kuwait, Bahrain, and NE Saudi Arabia), which spans a 40-years period (1973–2012). The first part of this study analyzes climate variability in the N Gulf, and relates them to teleconnection patterns …
In a recent letter, Ricke and Caldeira (2014 Environ. Res. Lett. 9 124002) estimated that the timing between an emission and the maximum temperature response is a decade on average. In their analysis, they took into account uncertainties about the carbon cycle, the rate of ocean heat uptake and the …
Victoria — The Seychelles minister for Environment, Energy and Climate Change, Didier Dogley, has announced that Seychelles is all set to become the first country in the world that has implemented a comprehensive spatial plan for its entire ocean territory. The Indian Ocean archipelago of 115 islands, scattered through almost …
SANGSAD BHABAN : The Jatiya Sangsad yesterday unanimously passed the “Oceanographic Research Institute Bill, 2014″ aimed at setting up a research institute to extract sea resources and ensure their proper usages, reports BSS. State Minister for Science and Information and Communication Technology (ICT) Architect Yafes Osman proposed the bill for …
On a summer day in 1885, three Hawaiian princes surfed at the mouth of the San Lorenzo River at Santa Cruz in California on crudely constructed boards made from coastal redwoods, bringing the sport to the North American mainland. Today their wave-riding successors consult satellite weather forecasts on smartphones before …
When it comes to carbon dioxide emissions, the first environmental problem that comes to mind is climate change. As humans pump more of this greenhouse gas into the air, the Earth gets warmer, and the climate changes in ways that could damage the economy, public health, infrastructure and society. But …
It's no secret that ocean acidification is wreaking havoc on the corals, sea stars, sharks and others that live beneath the waves. But now new research shows that this phenomenon is hitting closer to home and threatening US coastal communities, too. A lot of marine life may face extinction in …
Ocean acidification is a global, long-term problem whose ultimate solution requires carbon dioxide reduction at a scope and scale that will take decades to accomplish successfully. Until that is achieved, feasible and locally relevant adaptation and mitigation measures are needed. To help to prioritize societal responses to ocean acidification, we …
Since the end of the twentieth century, global mean surface temperature has not risen as rapidly as predicted by global climate models (GCMs). This discrepancy has become known as the global warming ‘hiatus’ and a variety of mechanisms have been proposed to explain the observed slowdown in warming. Focusing on …
In this article, we pointed out that understanding the physiology of differential climate change effects on organisms is one of the many urgent challenges faced in ecology and evolutionary biology. We explore how physiological ecology can contribute to a holistic view of climate change impacts on organisms and ecosystems and …
It turns out that our world's seas are quickly becoming ecosystems where species are at risk for extinction. Scientists have discovered that 20 to 25 percent of species in our oceans are now threatened with extinction. In order to better understand the state of species in our world's oceans, the …
The world's oceans are heating at the rate of two trillion 100-watt light bulbs burning continuously, providing a clear signal of global warming, according to new study assessing data from a global fleet of drifting floats. The research, published on Tuesday in the journal Nature Climate Change, used data collected …
Increasing heat content of the global ocean dominates the energy imbalance in the climate system. Here we show that ocean heat gain over the 0–2,000 m layer continued at a rate of 0.4–0.6 W m−2 during 2006–2013. The depth dependence and spatial structure of temperature changes are described on the …
