The Eco News Roundup brings stories and commentary about issues related to climate change, renewable energy and the environment.
One of the world’s top economists has written an expert court report that forcefully supports a group of children and young adults who have sued the federal government for failing to act on climate change.
Joseph Stiglitz, who was awarded the Nobel Memorial Prize for economics in 2001 and has written extensively about environmental economics and climate change, makes an economic case that the costs of maintaining a fossil fuel-based economy are “incalculable,” while transitioning to a lower-carbon system will cost far less.
The government, he writes, should move “with all deliberate speed” toward alternative energy sources.
Earth’s global warming fever spiked to deadly new highs across the Northern Hemisphere this summer, and we’re feeling the results—extreme heat is now blamed for hundreds of deaths, droughts threaten food supplies, wildfires have raced through neighborhoods in the western United States, Greece and as far north as the Arctic Circle.
At sea, record and near-record warm oceans have sent soggy masses of air surging landward, fueling extreme rainfall and flooding in Japan and the eastern U.S. In Europe, the Baltic Sea is so warm that potentially toxic blue-green algae is spreading across its surface.
There shouldn’t be any doubt that some of the deadliest of this summer’s disasters—including flooding in Japan and wildfires in Greece—are fueled by weather extremes linked to global warming, said Corinne Le Quéré, director of the Tyndall Centre for Climate Change Research at the University of East Anglia.
One of the longest and most consequential campaigns against science in modern history is becoming more extreme—and turning against its originators
A domino-like cascade of melting ice, warming seas, shifting currents and dying forests could tilt the Earth into a “hothouse” state beyond which human efforts to reduce emissions will be increasingly futile, a group of leading climate scientists has warned.
This grim prospect is sketched out in a journal paper that considers the combined consequences of 10 climate change processes, including the release of methane trapped in Siberian permafrost and the impact of melting ice in Greenland on the Antarctic.
To the chagrin of the tourist industry, the Great Barrier Reef has become a notorious victim of climate change. But it is not the only Australian ecosystem on the brink of collapse.
Our research, recently published in Nature Climate Change, describes a series of sudden and catastrophic ecosystem shifts that have occurred recently across Australia.
These changes, caused by the combined stress of gradual climate change and extreme weather events, are overwhelming ecosystems’ natural resilience.
FORT MYERS, Fla. – Hundreds of sea turtles have washed up on Southwest Florida beaches this year in a mass mortality event that researchers say will impact the recovery of the protected species.
Seventeen have been recovered off Sanibel and Captiva islands near Fort Myers in the past week.
“Our average for the entire year is usually around 30 or 35, but we’ve had 53 in June and July alone,” said Kelly Sloan, a sea turtle researcher at the Sanibel-Captiva Conservation Foundation on Sanibel.
Sloan said foundation has picked up 91 sea turtles on the islands since a red tide bloom started in October.
“Most of them have been mature adults, and only one in 1,000 make it to adulthood,” Sloan said. “It takes a loggerhead 25 to 30 years to mature, so that really does have a significant impact on their recovery.”
Scorching weather across the globe makes fields too dry for crops, rivers too warm to cool power plants, and leaves wind turbines idle – and it’s pushing commodities prices higher
At BPI Campus our Progressive Agenda is:
1. People matter more than profits.
2. The earth is our home, not our trash can.
3. We need good government for both #1 and #2.
