Quote:CNN's Five Things:
Australia's Great Barrier Reef is suffering its sixth mass bleaching event due to heat stress caused by climate change, the reef's managers confirmed today. The update comes mid-way through a 10-day monitoring mission by scientists who are considering whether to add one of the world's seven natural wonders to their "in danger" list." According to a biologist monitoring the project, more than half of the living coral seen from the air is severely bleached completely white and are producing fluorescent pigments in an attempt to protect their tissue from the intense sun during marine heatwaves. This is the fourth mass bleaching event in six years and the first since 2020, when about one quarter of the reef showed signs of severe bleaching. Previous bleaching occurred in 1998 and 2002.

In actuality, according to our federal Emissions Reduction Minister, Angus Taylor, Australia has reduced emissions faster than 15 other members of the G20. Australia has delivered a 20% emissions reduction since 2005, which is a better performance than the US, Canada, and New Zealand. Our emissions now equate to only 1.3% of the global total.

Climate tech firm to launch scaled-up plant sucking CO2 from air

A system like that should have cutoff valves specifically for stopping gas escape if the piping gets breached. I don't understand why these valves haven't been closed already, even if it takes saturation divers to go down and close them. Or have the well heads themselves been blown up?

No, there are no shutoff valves along the length of the thing because of access problems if they were to malfunction. Those lines are always full of gas, liquefied gas for negative buoyancy, you don't want the things floating to the surface which they could do if empty. 100,000 tons of liquid gas will take months to boil off.

Saturation diving is routine, so that's gonna need further elaboration. As to bouyancy the lines can be anchored to not float when empty with such common devices as concrete. That the system wasn't designed for access or accident sounds very much like it was designed with its top priority that its total cost not exceed $5.95. Which wouldn't be surprising but definitely disgusting that so critical a system was permitted to be built so slapdash. Quote:Europe is warming at twice the rate of the rest of the world.

COP15 agreeent has been reached with member countries agreeing to protect 30% of their landmass to preserve biodiversity, an 11 hour agreement. Of course, much like the Paris Accord of 2015, it doesn't contain any mechanism to force countries to comply beside shame, but it's at least a positive statement to preserve our dying ecosystems.

It also privileges the worlds worst offenders, who have landmass to spare, that they aren't exactly sacrificing to continue not utilizing.
From this One Earth article:
"Ultimately, even relatively modest warming is expected to increase the risk that various climatic tipping points will be crossed—causing large changes in the future state of Earth’s climate system, thereby adding further amplifying feedbacks. Despite major recent progress in incorporating a host of interacting feedbacks, climate models may still be underestimating the acceleration in global temperature change that a large and interrelated set of amplifying feedback loops and tipping points could cause. In a likely short-term scenario, our lack of dramatic emission reductions could result in a future with ongoing and intensifying climate impacts. In the worst case long-term scenario, interactions among feedback loops could result in an irreversible drift away from the current state of Earth’s climate to a state that threatens habitability for humans and other life forms. In any case, the accuracy of climate models is of vital importance since they guide climate mitigation efforts by informing policymakers about the expected effects of anthropogenic emissions." The article identified 41 separate feedback loops, 27 of which are positive and amplify warming.

I am not a climate scientist. But I am an experienced gardener. It has become obvious to me that the average last frost date in Spring over the last couple decades has become at least a week earlier and the average first frost date in Fall is about a week or two later. I recognize that is not precise, but my garden reacts to the changes, so I am doing the same.
I have a detailed system of when to plant seeds inside under lights to grow them to where they succeed transplanted outdoors. I changed my schedule by a week a few years ago, and I may change it by another week soon. I understand that local conditions don't prove world-wide changes. But when they do for 20 years locally, it is not just random odd weather. I do dislike making planting plans from local events. But when things become consistent, I have to adjust to that. For this particular post, I won't even get into worldwide climatic events and measurements. I'll leave that to others. But after 50 years of gardening in the same general place, I can sure see a difference!
Never try to catch a dropped kitchen knife!

Pretty cool stuff. Your anecdotal experience matches up with first and final frost dates in the us - we have frost maps going back a century. The growing season has extended about a month - two weeks on each end, in that century. Alot of it just in the last two decades. On the surface that would seem like a good thing - but what really hurts (and I imagine especially hurts the smaller a garden - with less of everything to lose) are the "freak" weather events -in- the growing season. Air quotes there because they've become the new normal. Strong winds blowing over tall stands when it should be mild. Cold snaps, heat waves, wet when it should be dry, dry when it should be wet. Early and late bugs. Faster spread of disease in humid conditions. It's gotten to the point where a single 30x72 high tunnel has approximately the same productive output (and net income) as a field acre.

How about a sun curtain?
Tow an asteroid to a proper distance from the sun, get it established in an orbit that keeps it permanently in eclipse between earth and sun. Then vaporize it with thermonuclear detonations such that the debris obstructs a calibrated percentage of the solar energy reaching earth. Obviously there are many logistical issues to resolve, and determine just what percent of what the sun sends to earth is ideal. But having established such a curtain, it could be adjusted, by adding another blasted asteroid, or using an intact asteroid to pass through the curtain and "vacuum" some of it away by gravitational attraction. The earth biosphere evolved across aeons with the natural quantity of sunlight, but we've artificially altered the biosphere such that what's natural is now too much, as atmospheric composition magnifies the sun's effects. A curtain would offer a solution that doesn't depend on universal cooperation from an anarchy of nations. (06-29-2023, 07:14 PM)airportkid Wrote: How about a sun curtain?

Glad you like it Chas, I got a 1st in economics and psychology at university and it's my baby/brainchild. I wish I knew how to publicise this reform/revolution. I wrote a "script" for the possible creation of a video espousing the benefits of SAUBI - they go faaaaaar beyond avoiding climate change apocalypse. Ah, what the hell, here it is:
1. Videos of climate protest roadblocks (scientists, doctors, the more respected the better), HS2 marching forward and planes chucking out pollution. Narrator: "The government has declared a climate emergency and yet very little has changed. A Status Adjusted Universal Basic Income could be the wider societal reform needed, fundamentally addressing our destruction of the planet and with many wider benefits to boot. " 2. Videos of “rats racing” (animated perhaps), clips of us using our luxuries. “As things stand, trying to make as much money as possible is the standard way of life – the rat race, if you will. This despite the fact that we in the West are overwhelmingly bathed in luxury, barring financial mismanagement, able to eat whatever we want whenever we want, smartphones, central heating, personal cars, snazzy trainers etc etc etc. The government's absurd definition of absolute poverty is simply meaningless, being based on relative measures alone, and utterly divorced from the World Health Organisation's definition of two dollars a day.” 3. Videos of environmental destruction and obscene wealth. “A Status Adjusted Universal Basic Income, status adjusted so, for example, children and millionaires get a far lower amount, SAUBI for short, could take the emphasis OFF boundless consumerism, economic growth and wealth acquisition. Given the damage we're currently doing to the planet through Climate Change and ecological destruction that has to happen, and could easily be paid for through harvesting just a fraction of the obscene levels of wealth held by the very wealthiest in society.” 4. Videos of beaming proud green SAUBI living people. Automated call-centres and factories. Somebody selling drugs and declining to claim unemployment benefit. “As automation of the goods and services industries continues apace, the level of economic inactivity is ever increasing. Successive governments have been revising down the unemployment figures for many decades by redefining the way they measure it, in order to appear to “out do” the previous administration. If you don't claim unemployment benefits, you're not unemployed, for example.” 5. Videos of a beaming “Green SAUBI person,” insurance sales, gambling advertising and cold calling. “There need be no pressure for those living solely on SAUBI to find paid work – living on SAUBI, consuming and polluting relatively little, would be praiseworthy. Much unnecessary, unpleasant, guilt ridden and damaging economic activity would stop under SAUBI, as SAUBI living would be preferable for the individual. Unnecessary, polluting government funded projects put in effect purely in the name of “creating jobs” would also no longer be necessary.” 6. Videos of something breaking/being broken, depression, anxiety, substance abuse (smack and alcohol), over-eating (obesity), “The way things stand if you're “not working” you are “broken” according to how the language operates. What a blow to anybody's self esteem, to be thought of as “broken” by society, let alone “dole scum.” All those unable to find work due to having a criminal record? All those unable to work due to disability? Broken, one and all. Many suffer depression and anxiety due to this, many more abuse substances. 7. Videos of crimes being committed and a happy prisoner back on the block. “Why is there such a high reoffending rate for released prisoners? It's not only that they struggle to find satisfying work which provides decent self-esteem once free, but also because there's a sense of community and belonging in prison, sorely missing in our dog eat dog rat race society. At base, when people are told they're societal down and outs, people feel like rubbish, and when people feel like rubbish, we behave badly.” 8. All positive videos, people with friends and family, relaxing in beautiful nature, playing sport, painting, reading, partying, watching films and cooking. “SAUBI is a caring policy, looking after people's well-being, self-esteem and the environment by taking the onus off dog eat dog rat race boundless greed, consumption and materialism. Who knows what further knock on positive effects that "shift" from the current socio-economic system might have for society at large. After all, the best things in life are free, and true happiness comes from having good relations with fellow human beings and decent self esteem, not boundless consumerism.” ETA: just re-read it (wrote it several years ago) and it could be improved a lot I think.
