Arctic ice melt may cause “bromine explosion,” depleting ozone and releasing mercury

By The State Column A new study conducted by NASA finds that Arctic ice is melting at a rate far faster than previously expected, increasing the rate of release of a number of deadly chemicals. The study, published and conducted by NASA’s Goddard Space Flight Center, finds the oldest and thickest arctic sea ice is … Continue reading Arctic ice melt may cause “bromine explosion,” depleting ozone and releasing mercury

Ocean acidification may be worse now than during last four major mass extinctions

By Agence France-Presse High levels of pollution may be turning the planet’s oceans acidic at a faster rate than at any time in the past 300 million years, with unknown consequences for future sea life, researchers said Thursday. The acidification may be worse than during four major mass extinctions in history when natural pulses of … Continue reading Ocean acidification may be worse now than during last four major mass extinctions

Oceans becoming increasingly acidic as carbon emissions are absorbed

By Katharine Gammon The oceans have already absorbed about one-third of the 500 billion tons of carbon dioxide that human activity has added to the atmosphere since the industrial revolution. Absorbing carbon dioxide reduces the pH of seawater, indicating an increase in its acidity. While more attention has been focused on the ecological fragility of … Continue reading Oceans becoming increasingly acidic as carbon emissions are absorbed

Marine Biodiversity Loss Due to Global Warming Will Be Severe

The biodiversity loss caused by climate change will result from a combination of rising temperatures and predation — and may be more severe than currently predicted, according to a study by University of British Columbia zoologist Christopher Harley. The study, published in the current issue of the journal Science, examined the response of rocky shore … Continue reading Marine Biodiversity Loss Due to Global Warming Will Be Severe
