A new study reveals that in the past large land animals, whales, seabirds and fish played a vital role in recycling nutrients from the ocean depths, spreading them far and wide across the globe and taking them deep inland. However, the paper says massive declines in their populations coupled with the extinction of most of […]
The fires that blazed in Indonesia’s rainforests in 1982 and 1983 came as a shock. The logging industry had embarked on a decades-long pillaging of the country’s woodlands, opening up the canopy and drying out the carbon-rich peat soils. Preceded by an unusually long El Niño-related dry season, the forest fires lasted for months, sending […]
Soil acidification from acid rain that is harmful to plant and aquatic life has now begun to reverse in forests of the northeastern United States and eastern Canada, according to an American-Canadian collaboration of five institutions led by the U.S. Geological Survey. The new research shows that these changes are strongly linked to acid rain […]
Annual snow accumulation on West Antarctica’s coastal ice sheet increased dramatically during the 20th century, according to a new study published today (Wednesday 4 November) in the American Geophysical Union journal Geophysical Research Letters. The last three decades saw more snow build up on the ice sheet than at any other time in the last 300 years. The […]
Germany’s Volkswagen said Tuesday (3 November) an internal probe had found that 800,000 more vehicles showed “inconsistencies” on carbon dioxide emissions, including the first petrol engines. Among the engines affected are 1.4, 1.6 and 2.0 litre motors of VW, Skoda, Audi and Seat vehicles, said a VW spokesman, adding that these cars had been found […]
Using in-season vegetables to lose weight works all year round. Slimming down after having my sons took some work, but I had the season on my side. Both of their birthdays are in May, so summer’s glorious bounty of vegetables made losing weight seem relatively simple: I’d pick whatever veggies looked fresh at the market […]
Imagine you are a parent, and that out of the blue, you get a letter from your child’s school telling you not to worry — that they’re ready to evacuate or shelter in place if an underground fire at a nearby landfill reaches radioactive waste on the same property. That’s pretty much what happened recently […]
Melting ice in West Antarctica is a major concern for global sea levels, and a key area may already be unstable enough to unleash three meters of ocean rise, scientists said Monday. The study follows research out last year, led by NASA glaciologist Eric Rignot, warning that ice in the Antarctic had gone into a […]
Genetic data show the grizzly bear population in the Greater Yellowstone Ecosystem has grown since the 1980s with no loss in genetic diversity, according to a report by the Interagency Grizzly Bear Study Team. Results indicate that the effective population size of Yellowstone grizzly bears, or the number of individuals that contribute offspring to the […]
As a result of increasing atmospheric carbon dioxide concentrations, the chemistry of the Southern Ocean is expected to change so fast over the next few decades that tiny creatures at the base of the food web may soon struggle to form their shells. New research by scientists from UH Mānoa and the University of Alaska, Fairbanks […]
