Increase in ocean acidity affects the marine nitrogen cycle
More carbon dioxide in the atmosphere (CO2) means more carbon dioxide dissolves in the oceans. As that happens the acidity of the oceans increases (technically, the pH decreases). This process is chemically obvious and the data indicates that ocean acidification is occurring and increasing. The impact on life in the seas is complex. Many studies [...]

The problem with grasping the ocean acidification problem
Sometimes the scale of a problem defies attempts to precisely define its reality and impact. Global warming is one such problem. Acidification of the oceans is another. These both represent tangible changes, one to the earth’s atmosphere; the other to the seas. Scientists have for years taken measurements, made comparisons, and generally (as in a [...]

New report: Ocean acidification worsens
The good news for the climate is that the oceans can absorb an enormous amount of carbon dioxide, a huge buffer against global warming. The bad news is for the oceans. When sea water absorbs CO2 it has the nasty habit of turning some of it into acid. This has been going on for decades [...]

Study: Oceans may be losing capacity as carbon sink
As the December Copenhagen climate summit approaches, it’s not surprising that a spate of new climate studies is appearing. In this case a new study presents data and interpretation for the ability of the Earth’s oceans to absorb CO2 – to act as a carbon sink.

Update: New figures for CO2 and global warming
Very near the heart of the global warming crisis are the figures relating to the output of carbon dioxide from human sources, the increase of CO2 in the atmosphere, and the ability of the Earth to absorb it through carbon sinks such as the oceans, land masses, and biotic materials. Gathering the massive amount of [...]
New study: Atmospheric carbon-dioxide unchanged since 1850
Anything that remotely implies scientific studies have miscalculated factors in global climate change is fodder for those who oppose the notion of global warming. So when a respected scientist, Dr. Wolfgang Knorr from the University of Bristol publishes a paper with results that indicate the level of carbon dioxide in the atmosphere has remained virtually [...]

Ocean acidification – fewer shellfish
Oceans are mighty, big, and wide – but they are not indestructible. We’ve known for some time that Earth’s ocean ecology is threatened. Overfishing, pollution, warming have all come under the spotlight. Scientific studies continue to arrive that document various aspects of the decline of the oceans. Here’s a pioneer study that spotlights the delectable [...]
