Climate change will cause Pacific’s low-oxygen zone to expand even more by 2100

WASHINGTON, November 29, 2022 — For thousands of kilometers along the western coasts of the Americas, low-oxygen waters known as oxygen minimum zones stretch out into the Pacific. In part due to climate change, this oxygen-starved region is likely to get wider and deeper, expanding by millions of cubic kilometers by the end of the […]

To prevent the next pandemic, restore wildlife habitats

Preserving and restoring natural habitats could prevent pathogens that originate in wildlife from spilling over into domesticated animals and humans, according to two new companion studies. The research, based in Australia, found that when bats experience loss of winter habitat and food shortages in their natural settings, their populations splinter and they excrete more virus. […]

NASA Study: Rising Sea Level Could Exceed Estimates for U.S. Coasts

By 2050, sea level along contiguous U.S. coastlines could rise as much as 12 inches (30 centimeters) above today’s waterline, according to researchers who analyzed nearly three decades of satellite observations. The results from the NASA Sea Level Change Team could help refine near-term projections for coastal communities that are bracing for increases in both […]

There’s room for improvement in a popular climate-smart agricultural practice, Stanford-led study shows

The promise for American agriculture is tantalizing: healthier soil, more carbon kept in the ground, less fertilizer runoff, and less need for chemicals. The reality of planting cover crops during the off-season – a much-touted and subsidized approach to climate change mitigation – is more complicated, according to new Stanford University-led research. The study, published Nov. 8 […]

New Audubon Study: Climate Change Threatens Bird Populations in the National Wildlife Refuge System

NEW YORK (October 26, 2022) – In a survey of all 525 refuges in the National Wildlife Refuge System, scientists with the National Audubon Society have found half of the birds throughout the system will see changes in the environmental suitability of their habitats if global temperatures are allowed to rise unchecked. The result could […]

Methane ‘Super-Emitters’ Mapped by NASA’s New Earth Space Mission

NASA’s Earth Surface Mineral Dust Source Investigation (EMIT) mission is mapping the prevalence of key minerals in the planet’s dust-producing deserts – information that will advance our understanding of airborne dust’s effects on climate. But EMIT has demonstrated another crucial capability: detecting the presence of methane, a potent greenhouse gas. In the data EMIT has […]

Seasonal changes in Antarctic ice sheet flow dynamics detected for the first time

Certain estimates of Antarctica’s total contribution to sea-level rise may be over, or even underestimated, after researchers detected a previously unknown source of ice loss variability. In a new paper published in The Cryosphere, researchers using Copernicus Sentinel-1 data, found that glaciers feeding the George VI Ice Shelf speed up by approximately 15% during the Antarctic summer. This is the […]

As Winters Warm, Nutrient Pollution Threatens 40% of U.S.

October 5, 2022 – Scientists are ringing alarm bells about a significant new threat to U.S. water quality: as winters warm due to climate change, they are unleashing large amounts of nutrient pollution into lakes, rivers, and streams. The first-of-its-kind national study finds that previously frozen winter nutrient pollution—unlocked by rising winter temperatures and rainfall—is […]
