The Swiss company hoping to capture 1% of global CO2 emissions by 2025 #DAC

With a backdrop of green farmland and solar-clad barns, the plant is also a stone’s throw from the Gebrüder Maier fruit and vegetable company, which uses the captured CO2 to boost the growth of cucumbers, tomatoes and aubergines in its large greenhouses. Continue reading →

Judi Bari: Revolutionary Ecology and Biocentrism

"Anyone who has ever dealt with the Forest Service, California Department of Forestry, the Endangered Species Act, or anything like that knows that science is used as the authority for the kind of relentless assault on nature in this society. And science is presented to us as neutral, as an objective path to knowledge, as something that's value-free." --Judi Bari Continue reading →

Gradual CO2 buildup can trigger sudden climate tipping points

“Our simulations indicate that even small changes in the CO2 concentration suffice to change the circulation pattern, which can end in sudden temperature increases,” said Zhang. Continue reading →

Human race is doomed if we do not colonise the Moon and Mars, says Stephen Hawking

Hawking is right about the threat from an extinction-level meteorite strike, and it is certainly true that we are ruining this planet through overpopulation and global warming, but if we follow his advice, several thousand people will survive while billions will be left on Earth to die abruptly or slowly as events unfold.

Billions to face ‘deadly threshold’ of heat extremes by 2100, finds study | Carbon Brief

In the current climate, around 30% of the world’s population get 20 or more days per year above the “deadly” threshold. This percentage is increasing as global temperatures rise, the researchers say, and will rise further through the century – depending on how successfully we cut our carbon emissions.

Antarctica Is Melting, and Giant Ice Cracks Are Just the Start

Totten [glacier on E. Antarctica] will lose its ice more slowly than West Antarctica. The worst case coming out of Antarctica still seems to be centuries away. But it would mean abandoning many of the world’s largest cities, including New York, Los Angeles, Copenhagen, Shanghai, and dozens of others—and it’s looking less crazy all the time. “The fuse is lit,” says Blankenship. “We’re just running around mapping where all the bombs are.” Continue reading →

Climate Change Is Shrinking the Colorado River

"The Colorado River Basin and other areas around the globe at essentially the same latitudes, such as the Mediterranean region and areas of Chile, South Africa and Australia, are especially at risk for drying because they lie immediately poleward of the planet’s major deserts. These deserts are projected to stretch polewards as the climate warms. In the Colorado River basin, dry areas to the south are expected to encroach on some of the basin’s most productive snow and runoff areas." Continue reading →

We’ll Soon Be Using More Than Earth Can Provide: How Myopic Humanity Committed Suicide

This year we will begin overdrawing our resource bank account on August 2. Continue reading →

This Summer’s Gulf ‘Dead Zone’ Could Be Bigger Than Connecticut

Marine and coastal dead zones are the result of a phenomenon called hypoxia—a state of low dissolved oxygen that occurs when excess pollutants, such as nitrogen and phosphorus, accumulate in bodies of water. These nutrients feed blooms of algae that, when they die and decompose, deplete the oxygen in the surrounding water. Hypoxia is a silent killer, suffocating organisms that can't escape the low-oxygen zone quickly enough, and causing others to flee. Continue reading →

U.S. Quietly Removes 17 Sites From UN Biosphere Reserve Network

There has been no explanation for the removal. "As detailed by the conservation nonprofit George Wright Society, the biosphere program was launched in the 1970s to establish internationally designated protected areas, help minimize the loss of biological diversity, raise awareness on how cultural diversity and biological diversity affect each other, and promote environmental sustainability."--Lorraine Chow Continue reading →
