A rise of 2 degrees Celsius could change the pattern of seafloor diversity in unpredictable ways, experiment suggests.
It's not humanity alone that threatens life on earth. The bigger culprit is an economic and political system that relies on endless global appropriation of cheap food, energy, raw materials and labor.
Researchers say it is already too late for Miami and New Orleans, which will be overcome by rising sea levels caused by man-made climate change. Under a worst-case scenario, New York could be unlivable by 2085.
It may sound a bit unpalatable, but pee may be a better option for the Golden State than the desalination of ocean water.
Scientists are making some headway in figuring out what is killing millions of sea stars in the waters off the Pacific Coast, from British Columbia to Mexico.
Some fish species in increasingly acidic tropical seas are losing their sense of smell and becoming easier prey for predators.
Several marine species are reacting badly to the increasing acidity of the world's oceans, caused by climate change as carbon dioxide dissolves in the water.
By 2100, the world’s oceans will be warmer and more acidic, with less dissolved oxygen and lower yields of fish and shellfish, making life very difficult for up to 870 million people who rely on the sea for food, jobs and income.
The ocean may be mitigating some of the effects of global warming, but scientists say marine life is mortally threatened as the ocean becomes increasingly acidic, less oxygenated and warmer. And it's happening at a much faster pace than previously known.
Climatologists are puzzled that greenhouse gas emissions continue unabated, while the atmosphere is warming more slowly than they expected. Now two scientists in the U.S. think they know why.
