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 temporal and spatial dynamics of primary and secondary biomass/production in the Barents Sea since the late 1990s are examined using remote sensing data, observations and a coupled physical-biological model. Field observations of mesozooplankton biomass, and chlorophyll a data from transects (different seasons) and large-scale surveys (autumn) were used for …
Researchers have found that increasing ocean temperatures due to climate change will soon see reefs retaining and nurturing more of their own coral larvae, leaving large reef systems less interconnected. The study brought together an international group of researchers from NSU's Oceanographic Center; the Australian Research Council Centre of Excellence …
El Niño is a local warming of surface waters which takes place in the entire equatorial zone of the central and eastern Pacific Ocean and which affects the atmospheric circulation and direction of winds world-wide.
Change is taking place in the tropical Pacific Ocean, where NOAA (National Oceanic and Atmospheric Administration) researchers have found that carbon dioxide (CO2) concentrations have increased as much as 65 percent faster than atmospheric CO2 since 1998. Rising CO2 concentrations of this magnitude indicate that tropical Pacific waters are acidifying …
China remains under pressure to contain pollution in its offshore areas, although water quality of 95 percent of the country's territorial waters met standards in 2013, a report said on Wednesday. According to the report issued by the State Oceanic Administration (SOA), the quality of 44,000 square kilometers of sea …
Data and analysis from the Bureau of Meteorology and CSIRO show further warming of the atmosphere and oceans in the Australian region, as is happening globally. This change is occurring against the background of high climate variability, but the signal is clear. Air and ocean temperatures across Australia are now, …
An assessment of ocean acidification, presented at the UN Climate Change Conference in Warsaw in November 2013, starkly concluded that acidity is on track to rise 170 percent by the end of this century. As many key species are sensitive to changes in acidity, this would drastically impact ocean ecosystems, …
Despite ongoing increases in atmospheric greenhouse gases, the Earth’s global average surface air temperature has remained more or less steady since 2001. A variety of mechanisms have been proposed to account for this slowdown in surface warming. A key component of the global hiatus that has been identified is cool …
Ocean surface waves can be major hazards in coastal and offshore activities. However, there exists very limited information on ocean wave behavior in response to climate change, because such information is not simulated in current global climate models. This study made statistical projections of changes in ocean wave heights using …
Even the most remote deep-sea ecosystems are affected by climate change according to a study conducted by the National Oceanography Centre at the University of Southampton, UK. According to the study, seafloor dwellers will decline by up to 38% in the North Atlantic and over 5% globally over the next …
A new paper shows that global warming has continued over the past decade, and been manifested in different ways New research by Kevin Trenberth and John Fasullo of the National Center for Atmospheric Research investigates how the warming of the Earth's climate has behaved over the past 15 years compared …
We assess climate impacts of global warming using ongoing observations and paleoclimate data. We use Earth’s measured energy imbalance, paleoclimate data, and simple representations of the global carbon cycle and temperature to define emission reductions needed to stabilize climate and avoid potentially disastrous impacts on today’s young people, future generations, …
The indiscriminate disposal of plastic to the environment is of concern. Microscopic plastic litter (<5 mm diameter; ‘microplastic’) is increasing in abundance in the marine environment, originating from the fragmentation of plastic items and from industry and personal-care products. On highly impacted beaches, microplastic concentrations (<1mm) …
New research has found that the middle depths of the Pacific Ocean have warmed 15 times faster in the last 60 years than they did during apparent natural warming cycles in the previous 10,000 years. Published in the journal Science, the study supports the idea that oceans are taking up …
The El Niño–Southern Oscillation (ENSO) drives substantial variability in rainfall, severe weather, agricultural production, ecosystems and disease in many parts of the world. Given that further human-forced changes in the Earth’s climate system seem inevitable, the possibility exists that the character of ENSO and its impacts might change over the …
Failure to protect Antarctic waters long-term could leave it vulnerable to oil drilling and fishing within 15 years Talks to create the world’s two largest marine reserves in the Antarctic could be undermined by a last-ditch push for a “sunset clause” that would allow protections from fishing and oil drilling …
The world's oceans are under greater threat than previously believed from a "deadly trio" of global warming, declining oxygen levels and acidification, an international study said on Thursday. The oceans have continued to warm, pushing many commercial fish stocks towards the poles and raising the risk of extinction for some …
Monsoons, cyclones & extreme events – Role of oceans - a presentation by M. R. Ramesh Kumar at CSE Annual South Asian Media Briefing Workshop on Climate Change, 2013 held in New Delhi from September 18-19, 2013.
Worldwide, 2012 was among the 10 warmest years on record according to the 2012 State of the Climate report released by the American Meteorological Society (AMS). The peer-reviewed report, with scientists from NOAA’s National Climatic Data Center in Asheville, NC serving as lead editors, was compiled by 384 scientists from …
One purpose of wind turbines is to provide pollution-free electric power at a reasonable price in an environmentally sound way. In this focus issue the latest research on the environmental impact of wind farms is presented. Offshore wind farms affect the marine fauna in both positive and negative ways. For …
