Like all healthy wetlands, the Mississippi Delta was once a carbon sink, an ecosystem that sucks carbon dioxide out of the air and stores it in the ground. Now it’s unclear if it still is. As the delta rapidly sinks into the sea, it could release into the atmosphere thousands of years’ worth of stored-up […]
In the global effort to mitigate carbon dioxide levels in the atmosphere, all options are on the table — including help from nature. Recent research suggests that healthy, intact coastal wetland ecosystems such as mangrove forests, tidal marshes and seagrass meadows are particularly good at drawing carbon dioxide from the atmosphere and storing it for […]
Today, there are an estimated 370 million indigenous peoples across the world. Although they represent a relatively small portion of the global population, they account for the largest portion of linguistic and cultural diversity on Earth. The lands and waters traditionally occupied or used by indigenous peoples are also estimated to contain the majority of […]
Millions of pounds’ worth of funding to tackle global overfishing and protect coral reefs will be announced at a major conference in Indonesia this week. Politicians, marine experts and philanthropists will convene in Bali at the Our Ocean conference on Monday to agree commitments on how to address the pressures facing our oceans, including rising […]
On 106 acres in Fishlake National Forest in Richfield, Utah, a 13-million-pound giant has been looming for thousands of years. But few people have ever heard of him. This is “the Trembling Giant,” or Pando, from the Latin word for “I spread.” A single clone, and genetically male, he is the most massive organism on […]
At the Rio conference 25 years ago, the Union of Concerned Scientists – which included 1,700 leading researchers, a number of them Nobel prizewinners – issued a warning to humanity about the dire consequences of failing to curtail environmental destruction. Last year, world scientists issued a second warning, bemoaning the lack of progress since the […]
When Florence slogged ashore in North Carolina last week, coastal wetlands offered one of the best lines of defense against the hurricane’s waves and surge. A new study predicts such wetlands will survive rising seas to buffer the world’s coastlines against future storms and provide their many other ecological and economic benefits, but only if […]
IIASA researchers have developed a general decision-making framework to support policy decisions on the management of water resources, which, for the first time, explicitly takes into account the associated uncertainties. Reliable access to clean water is one of the key aspects addressed by the UN Sustainable Development Goals (SDGs). In fact, most of the SDGs […]
The Arctic is rapidly warming, with stronger effects than observed elsewhere in the world. The Arctic regions are particularly important with respect to climate change, as permafrost soils store huge amounts of the Earth’s soil carbon (C). Warming of Arctic soils and thawing of permafrost can have substantial consequences for the global climate, as the […]
Hurricane Olivia moved from the Eastern Pacific into the Central Pacific and is expected to affect Hawaii. NASA’s Aqua satellite the northeast and southwestern quadrants of the storm to be the most powerful on Sept. 10. Hurricane Olivia moved from the Eastern Pacific into the Central Pacific and is expected to affect Hawaii. NASA’s Aqua […]
