The Navy takes climate change seriously

The 2018 National Defense Authorization Act has ordered the Pentagon to identify the top 10 military bases threatened by climate change for the Navy and the other service branches by November. The congressional mandate requires the Defense Department to examine each threatened military installation for the effects of rising sea tides, increased flooding, drought, desertification,…

Protected marine areas: expensive and misplaced

Many marine protected areas are often unnecessarily expensive and located in the wrong places, an international study has shown. The University of Queensland was part of research which found protected areas missed many unique ecosystems, and have a greater impact on fisheries than necessary. A collaboration with the University of Hamburg, Wildlife Conservation Society and…

NOAA’s Acting Chief Ignoring Climate Change

Environmental and science advocates called the shift among the starkest examples to date by the Trump administration to undermine federal work on global warming. President Donald Trump and many of his top advisers deny manmade climate change, which has led to his high-profile decisions such as pulling the United States out of the Paris climate…

Nanomaterials = more algae outbreaks?

The last 10 years have seen a surge in the use of tiny substances called nanomaterials in agrochemicals like pesticides and fungicides. The idea is to provide more disease protection and better yields for crops, while decreasing the amount of toxins sprayed on agricultural fields. But when combined with nutrient runoff from fertilized cropland and…

A rebound promotes ice-sheet stability

The unexpectedly rapid rebound of the Amundsen Sea Embayment (ASE) may help stabilize the West Antarctic Ice Sheet against catastrophic collapse, says a new study offering a rare silver-lining in glacier research. The marine portion of the WAIS accounts for a quarter of the world’s ice contribution to global sea level rise and is currently…

US oil & gas methane emissions 60 percent higher than estimated

The U.S. oil and gas industry emits 13 million metric tons of the potent greenhouse gas methane from its operations each year, 60 percent more than estimated by the U.S. Environmental Protection Agency, according to a new study published today in the journal Science. Significantly, researchers found most of the emissions came from leaks, equipment…

Clean water from seeds and sand

Carnegie Mellon University’s Biomedical Engineering and Chemical Engineering Professors Bob Tilton and Todd Przybycien recently co-authored a paper with Ph.D. students Brittany Nordmark and Toni Bechtel, and alumnus John Riley, further refining a process that could soon help provide clean water to many in water-scarce regions. The process, created by Tilton’s former student and co-author…

Climate change becoming the major threat to biodiversity

The pace of change is set to outstrip loss to vertebrate communities caused by land use for agriculture and settlements, which is estimated to have already caused losses of over ten per cent of biodiversity from ecological communities. Previous studies have suggested that ecosystem function is substantially impaired where more than 20 per cent of…

Limiting Asia’s growing water shortages

To examine the risk of water shortages on the continent, the researchers conducted detailed simulations of many plausible economic and climate pathways for Asia in the future, evaluating the relative effects of both pathways on water supply and demand. By studying cases in which economic change (or growth) continues but the climate remains unchanged —…

Start Treating Climate Change as a Real Emergency

For the Climate Mobilization Project, the climate crisis demands not incremental changes or gradual reductions in emissions, but an emergency response led by government that is on the scale of the response to World War II after the attack on Pearl Harbor. The group just picked up a grant from the Unitarian Universalist Congregation of…
