The ocean helps relieve our atmosphere of a lot of the excess carbon dioxide we've pumped into it. Here's how its "twilight zone" makes that happen, and how the impacts of climate change make it harder for the ocean to do its job.
Scientists have identified nine planetary boundaries that help regulate a livable planet. Human activities have pushed six of those nine critical Earth systems beyond safe limits, threatening the stability of life as we know it. Mongabay has consistently reported on all nine systems: Climate change,...

The Bleak, Defeatist Rise of “Climate Realism”
cross-posted from: https://slrpnk.net/post/20740784
Amid all the bad climate news flowing out of the Trump administration, you might have missed a quiet new consensus congealing in think tanks and big business. The targets set out by the Paris climate agreement, they argue—to limit global temperature rise to two degrees Celsius (3.6 degrees Fahrenheit)—are a lost cause. It’s time to prepare for a world warmed by at least three degrees Celsius.
Owing to “recent setbacks to global decarbonization efforts,” Morgan Stanley analysts wrote in a research report last month, they “now expect a 3°C world.” The “baseline” scenario that JP Morgan Chase uses to assess its own transition risk—essentially, the economic impact that decarbonization could have on its high-carbon investments—similarly “assumes that no additional emissions reduction policies are implemented by governments” and that the world could reach “3°C or more of warming” by 2100.

For 12 years, scientists thought they knew how much extreme heat human bodies could cope with. New research shows how wrong they were.

In the summer of 2023, a dozen people willingly walked into a steel chamber at the University of Ottawa designed to test the limits of human survival. Outfitted with heart rate monitors and temperature probes, they waited in temperatures of 42 degrees Celsius, or 107 degrees Fahrenheit, while the humidity steadily climbed, coating their bodies in sweat and condensation. After several hours, their internal body temperatures began ratcheting upward, as the heat cooked them from the outside in.
“Few people on the planet have actually experienced temperatures like this,” said Robert Meade, a postdoctoral researcher in epidemiology at the Harvard School of Public Health who led the study. “Imagine moisture condensing on the skin like a glass of water on a hot day. That’s how hot it was, compared to skin temperature.”
Their experiment tested the body’s ability to cope with extreme heat by exposing participants to temperatures
Inside Track x Food claims the UK food industry has 'reached a moment of threat to food security like none other we have seen'

The memo, shared with The Grocer, warns food businesses are woefully unprepared for challenges including soil degradation, extreme weather events, global heating and water scarcity and that yield, quality and predictability of food supply are all at severe risk.
It goes on to claim that companies’ risk mitigation strategies are being assured by major audit and assurance firms and giving false confidence to investors, whereas the true threat to the supply chain is far greater than companies have acknowledged.

Like heat waves, these periods of high atmospheric demand for water can damage crops and ecosystems and increase pressure on water resources. New research shows they’re becoming more severe.

Just as the pretension to ideally govern the climate failed, Biopolitics as a project to foster life also failed.
Pierre-Yves Cadalen calls for a new form of politics given the climate crisis:
“Ecopower, then, can be rewritten as the form of power from which humankind will decide if our time will be indefinitely transitory, or if it will abruptly end.”
The science is in. The choice is ours.
