A report released Monday at the UN climate summit showed that climate change threatens the survival of dozens of animal species from the emperor penguins to Australian koalas, AFP reported. The study from the International Union for the Conservation of Nature (IUCN), an intergovernmental group, warned that rising sea levels, ocean acidification and shrinking polar ice are taking a heavy toll on species already struggling to cope with pollution and shrinking habitats. Wendy Foden, an IUCN...

An international team of scientists led by the University of East Anglia (UEA) has developed a new method of measuring the absorption of CO2 by the oceans and mapped for the first time CO2 uptake for the entire North Atlantic. Published tomorrow in the journal Science, the peer-reviewed study will greatly improve our understanding of the natural ocean 'sinks' and enable more accurate predictions about how the global climate is changing. The new technique could also lead to the development of...

In a striking finding that raises new questions about carbon dioxide's (CO2) impact on marine life, Woods Hole Oceanographic Institution (WHOI) scientists report that some shell-building creatures"”such as crabs, shrimp and lobsters"”unexpectedly build more shell when exposed to ocean acidification caused by elevated levels of atmospheric carbon dioxide (CO2). Because excess CO2 dissolves in the ocean"”causing it to "acidify" "”researchers have been concerned about the...

First year-by-year study, 1765-2008, shows proportion declining The oceans play a key role in regulating climate, absorbing more than a quarter of the carbon dioxide that humans put into the air. Now, the first year-by-year accounting of this mechanism during the industrial era suggests the oceans are struggling to keep up with rising emissions"”a finding with potentially wide implications for future climate. The study appears in this week's issue of the journal Nature, and is expanded...

To have even a chance of saving the world's coral reefs from extensive damage caused by global warming, carbon emissions in industrialized countries need to be cut by 25% below their year 2000 levels by 2020 "“ and by 80-90% by 2050. That is the uncompromising warning delivered today by some of Australia's most eminent marine and environmental scientists in a briefing to Australian Members of Parliament and Senators, in Parliament House, Canberra. "The Great Barrier Reef (GBR)...

Australian marine scientists have issued an urgent call for massive and rapid worldwide cuts in carbon emissions, deep enough to prevent atmospheric CO2 levels rising to 450 parts per million (ppm). In the lead up to United Nations Copenhagen Climate Change Conference Professors Charlie Veron (former Chief Scientist, Australian Institute of Marine Science) and Ove Hoegh-Guldberg of the ARC Centre of Excellence for Coral Reef Studies and The University of Queensland, have urged the world's...

Stony Brook University researchers find elevated carbon dioxide concentrations impede growth and survival of bivalve larvae Relatively minor increases in ocean acidity brought about by high levels of carbon dioxide have significant detrimental effects on the growth, development, and survival of hard clams, bay scallops, and Eastern oysters, according to researchers at Stony Brook University's School of Marine and Atmospheric Sciences. In one of the first studies looking at the effect of ocean...

Humanity needs to act now to avoid threats to human well-being caused by irreversible damage to the Earth, its climate, species and life-supporting systems. Scientists say it has become essential to define what levels of such human-caused change are "Ëœsafe' and which are "Ëœunsafe', and to stay within these boundaries. The call comes from 28 of the world's most eminent environmental scientists, published today in the world's leading science journal, Nature. The...

Ocean Acidification
2013-04-01 10:32:20

Ocean acidification is the name that was given to the ongoing decrease in the pH of Earth’s oceans, a cause of the uptake of anthropogenic carbon dioxide from the atmosphere. About 30 to 40 percent of the carbon dioxide that is released by humans into the atmosphere dissolves into the lakes, oceans, and rivers. To maintain the chemical equilibrium, some of it reacts with the water to create carbonic acid. Some of these extra carbonic acid molecules react with a water molecule to provide a...

Rice Coral, (Montipora capitata), also known as Pore Coral, is a species of stony coral in the Acroporidae family. It is found in the tropical north and central areas of the Pacific Ocean at depths down to 66 feet. It is common in the waters near Hawaii, especially where the sea is turbulent. This is a reef-building species that forms colonies. As it matures, it develops tree-like branches. Its corallites are tiny and well separated by a calcareous (calcium carbonate) skeleton. The walls...

  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
