Seed banking not an option for over a third of threatened species

In paper published today in Nature Plants, researchers at the Royal Botanic Gardens, Kew, detail for the first time the scale of threatened species that are unable to be conserved in seed banks. The paper reveals that when looking at threatened species, 36 percent of ‘critically endangered’ species produce recalcitrant seeds. This means they can’t…

Global Warming effect  on Jet Stream Means More Extreme Weather.

Greenhouse gases are increasingly disrupting the jet stream, a powerful river of winds that steers weather systems in the Northern Hemisphere. That’s causing more frequent summer droughts, floods and wildfires, a new study says. The findings suggest that summers like 2018, when the jet stream drove extreme weather on an unprecedented scale across the Northern…

Manure is better for soil health

Ozlu and his team concluded that long-term annual application of manure improved most soil quality properties compared to inorganic fertilizer. “Increased electrical conductivity is one of the few negative impacts of manure,” Ozlu said. The team also measured the effects of larger and smaller doses of each treatment at different soil depths. This will provide…

Frequency of ocean storms may alter kelp ecosystems

A large-scale, long-term experiment on kelp forests off Southern California brings new insight to how the biodiversity of coastal ecosystems could be impacted over time as a changing climate potentially increases the frequency of ocean storms. Researchers at the University of Virginia and the University of California, Santa Barbara experimentally mimicked the loss of undersea…

World hunger and climate change

The total number of people who face chronic food deprivation has increased by 15 million since 2016. Some 821 million people now face food insecurity, raising numbers to the same level as almost a decade ago. The situation is worsening in South America, Central Asia and most regions of Africa, the report shows. It also…

Experts say it’s time to reflect on local food systems planning

Governments across the U.S. and Canada have made strides in their food systems planning efforts, with many recognizing within the past decade that the issue of food insecurity is just as important as maintaining other public infrastructure like roads and water systems. Still, questions remain: How are local governments engaging in the food system? Who…

Climate Denial a War on Health.

The list of crimes Donald Trump has committed against the planet, in just two years, is already so impeachably long that his slippery-fish climate denial registers as hardly more than a footnote. “I have a natural instinct for science,” the president bragged to the Associated Press Tuesday, a week after the U.N.’s IPCC raised the…

Correcting forest carbon stock estimates

It may be a small correction, but it is far from negligible as far as forest ecologists and carbon cycle specialists are concerned. The error lay in a formula established almost 50 years ago (in 1971) for calculating basic wood density. Given that basic density is used to assess the amount of carbon stored in…

Climate change – billionaires to blame

70% of global emissions come from 100 companies: Koch Industries’ annual carbon emissions bill is 24 million tons. Just like Exxon (who spent years and millions denying the climate change their own research told them was happening), Peter Thiel knows climate change is real, but he plans on Seasteading his way through it with a…

Costing out climate change

All of that wealth comes, ultimately, from the planet, and the climate. Specifically, it has come from a stable climate. William Nordhaus points out in his 2013 book “The Climate Casino” that “the last 7,000 years have been the most stable climatic period in more than 100,000 years.” The last 7,000 years have also seen…
