    As the world's oceans warm, their massive stores of dissolved carbon dioxide may be quick to bubble back out into the atmosphere and amplify the greenhouse effect, according to a new study.

    Around the world, people use quicklime to balance the pH of their fish tanks. Could governments do something similar to correct the pH of our acidifying oceans?

    Acidity is measured by its pH (power of hydrogen) value. Fresh water has a pH reading of 7. Readings below that are considered to be acidic. Those above 7 are alkaline. Surface sea water had a reading of 8.2 a century ago.

    Australia's meteorological service says its climate models indicate that the El Niño ocean-warming phenomenon may return later this year, replacing the stubborn La Niña that has altered global weather patterns for the past two years. El Niño brings its own set of weather disruptions, typically including drought from Australia to Indonesia and potent winter storms to the western United States.

    Lighter-coloured crops, aerosols in the stratosphere and iron filings in the ocean are among the measures being considered by leading scientists for "geo-engineering" the Earth's climate, leaked documents from the UN climate science body show.

    Layers of frozen sea water, known as sea ice, cap the Arctic Ocean. The ice grows dramatically each winter, and melts just as dramatically each summer. In the past decade, the melting has grown more dramatic, while growth has become less so, as you can see in our World of Change feature.

    If you want to see global warming's signature, look to the Arctic. Up north, the air is warming and the ice is melting. As all of that reflective ice goes away, the Arctic Ocean is soaking up more sunlight, further enhancing warming. Melting Arctic ice is also contributing significantly to sea level rise.

    As the world's climate warms, will the Pacific Ocean make matters worse by dumping extra heat into the atmosphere? Ancient fossils and the latest modelling both suggest such fears may be unfounded. But there is a downside: extreme weather caused by the Pacific's shifting waters might become more common.
