"Earth is now well outside of the safe operating space for humanity," says report in journal Science Advances. This update of planetary boundaries framework may serve as renewed wake-up call to humankind that Earth is in danger of leaving its #Holocene-like state. It may also contribute to guiding substantial human opportunities for sustainable development
Really important #paper in @Nature which includes @envagency#invertebrate monitoring data along with European datasets showing that recovery of #freshwater invertebrates has come to a halt since 2010
#Water pumped from deep underground helps #alfalfa grow at the Saudi-owned Fondomonte farm in the Butler Valley, in western Arizona
Saudi Arabia bans industrial scale farming of alfalfa, to protect its limited water supplies.
So they grow it in a #US desert and ship it back home, using AZ’s scarce water.
Perspective: The prior republican admin even blocked efforts to track the amount of water being used. #Arizona get saudi the fuck out. #natsec

Can I get some follow recommendations? I’m acutely aware that of the people I follow who post about our planet’s systems, most of them are climate people. I’d love to follow more people posting at a #systems level. Y’know, the people who distill down expert knowledge into consumable packets for the rest of us. Think #hydrology/ #freshwater/ #oceans, #biodiversity, #ecology, #biology, #agriculture, #energy, #economics, #geology#planetaryBoundaries … these kind of topics. Boosts appreciated!
The sea pinks/pink thrift in bloom. Mermaid Rock has been steadily eroding over the past couple of years and despite photographing this view repeatedly it now looks very different compared to the last time that Steve (my husband ) took it.
The sea is often this beautiful colour during the late spring and early summer. The clear sky gave little detail in the sunset but a vivid sky might have been a bit hectic for this scene! #Photography
"Overall, there is almost no ice over four years old remaining—it now comprises just 3 percent of the total ice cover. This is the same percentage as last year and contrasts starkly with the late 1980s when 30 to 35 percent of the Arctic Ocean’s ice was older than 4 years."
"... over the #SouthernHemisphere in recent decades. Increased contributions of meltwater from the #Antarctic#IceSheet, mostly from melting at depth due to increased warm deep water reaching the edge of the continent, has added #freshwater to the sea currents, making the water less dense. This lighter water flows up to the surface, increasing the stratification in the near-surface layer.
