The Eco News Roundup brings stories and commentary about issues related to climate change, renewable energy and the environment.
In the wake of the Fukushima disaster, Japan has idled all 50 of its nuclear reactors. While the central government and business leaders are warning a prolonged shutdown could spell economic doom, many Japanese and local officials see the opportunity for a renewable energy revolution.
A physicist argues that if we allow our overblown and often irrational fears of nuclear energy to block the building of a significant number of new nuclear plants, we will be choosing a far more perilous option: the intensified burning of planet-warming fossil fuels.
WASHINGTON — The world’s air has reached what scientists call a troubling new milestone for carbon dioxide, the main global warming pollutant.
Monitoring stations across the Arctic this spring are measuring more than 400 parts per million of the heat-trapping gas in the atmosphere. The number isn’t quite a surprise, because it’s been rising at an accelerating pace. Years ago, it passed the 350 ppm mark that many scientists say is the highest safe level for carbon dioxide. It now stands globally at 395.
A clear change in salinity has been detected in the world’s oceans, signalling shifts and an acceleration in the global rainfall and evaporation cycle. In a paper just published in the journal Science, Australian scientists from the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Lawrence Livermore National Laboratory, California, reported changing patterns of salinity in the global ocean during the past 50 years, marking a clear fingerprint of climate change.
The influence of the ground beneath us on the air around us could be greater than scientists had previously thought, according to new research that links the long-ago proliferation of oxygen in Earth’s atmosphere to a sudden change in the inner workings of our planet.
Environmental scientists at Harvard have discovered that the Arctic accumulation of mercury, a toxic element, is caused by both atmospheric forces and the flow of circumpolar rivers that carry the element north into the Arctic Ocean. While the atmospheric source was previously recognized, it now appears that twice as much mercury actually comes from the rivers.
Scientists from the Woods Hole Oceanographic Institution (WHOI) have conducted a new study to measure levels of carbon at various depths in the Arctic Ocean. The study, recently published in the journal Biogeosciences, provides data that will help researchers better understand the Arctic Ocean’s carbon cycle — the pathway through which carbon enters and is used by the marine ecosystem.
When leatherback turtle hatchlings dig out of their nests buried in the sandy Playa Grande beach in northwest Costa Rica, they enter a world filled with dangers. This critically endangered species faces threats that include egg poaching and human fishing practices. Now, Drexel University researchers have found that the climate conditions at the nesting beach affect the early survival of turtle eggs and hatchlings.
LOS ANGELES (AP) — Years of ferocious storms have threatened to gnaw away the western tip of a popular beachfront park two hours drive north of Los Angeles. Instead of building a 500-foot-long wooden defense next to the pier to tame the tide, the latest thinking is to flee.
It took some 10 million years for Earth to recover from the greatest mass extinction of all time, latest research has revealed. Life was nearly wiped out 250 million years ago, with only 10 per cent of plants and animals surviving.
Australia is riding an unprecedented wave of resources investment due to booming demand from Asia, with projects worth Aus$450 billion (US$435 billion) in the pipeline.
The world’s largest coral reef is not yet at sufficient risk to be declared in danger but UNESCO said the sheer number and scale of proposals including liquefied natural gas (LNG), tourism and mining projects could threaten it.
