Climate Change Could Choke Oceans for 100,000 Years
According to a simulation of planetary warming trends, failure to drastically cut greenhouse gas pollution within the next half century could choke Earth's oceans for the next 100,000 years.
With warmer temperatures reducing its ability to absorb oxygen, much of the water would become barren and lifeless. Oceanic food chains could be profoundly disrupted.
"What mankind does for the next several decades will play a large role in climate on Earth over the next tens of thousands of years," said geochemist Gary Shaffer of the University of Copenhagen.
New Science Could Help Solve Climate Crisis
A new science that seeks to fight climate change using methods like giant space mirrors might not work on its own, but when combined with cuts in greenhouse gases it may help reverse global warming, a research report said.
In the report published on Wednesday, researchers at Britain's University of East Anglia assessed the climate cooling potential of "geoengineering" schemes that also include pumping aerosol into the atmosphere and fertilizing the oceans with nutrients.
"We found that some geoengineering options could usefully complement mitigation, and together they could cool the climate, but geoengineering alone cannot solve the climate problem," said Professor Tim Lenton, the report's lead author.
