Is it already too late?
If so, will we reach tipping points no matter what policies we enact?
Will we actually turn ourselves into Venus?
If it's not too late, what exactly can we do to contribute to mitigating it?
Is there ANYONE out there who still doesn't consider this the issue of our times? — Xtrix
Geothermal isn't a resource for every place,and so is tidal. They can assist, but basically one has to remember that energy production is and will be determined by demand and supply of today. The fact is that we can have those long term plans, but the economic situation of today has a huge impact of just what actually will happen.Where is geothermal? Where is tidal energy? When the sun don't shine and the wind don't blow there's trouble a'brewin. — jgill
Coal usage has rebounded in the past year, wiping out declines in 2020 and interrupting a decades-long downward trend of use in advanced economies.
Trying to bounce back from Covid, the world has run headlong into an energy crisis. The last spike of this magnitude popped the 2008 bubble.
Crude oil is up 65% this year to $83 per barrel. Gasoline, above $3 per gallon in most of the country, is more costly than any time since 2014, with inventories at the lowest level in five years.
Meanwhile natural gas, which provides more than 30% of all U.S. electricity and a lot of wintertime heating, has more than doubled this year to $5 per million Btu.
Even coal is exploding, with China and India mining as fast as possible. The price of U.S. coal is up 400% this year to $270 per ton.
The situation is considerably worse in Europe, where electricity prices have quintupled and natgas prices have surged to $30/mm Btu—the energy equivalent of paying $180 for a barrel of oil.
All this is feeding into the inflation loop, pushing up the prices for energy-intensive metals like nickel, steel, silicon. Fertilizer, mostly made from natural gas, has ramped past 2008 record highs to nearly $1,000 a ton, obliterating the $300 to $450/ton range of the past few years. China announced this week it would halt fertilizer exports. Copper, perhaps the most vital raw material in building out a wind and solar industry, is near a record at $4.50 per pound. We’ll have to deal with inflation after surviving the challenge of not freezing to death this winter. “Only some form of government intervention that mandates large-scale power cuts and rationing to certain sectors can curb gas demand and temper gas prices materially this winter,” wrote Amrita Sen of Energy Aspects last week.
Whom can we blame for this mess? A combination of factors. It starts with central banks persisting with artificially low interest rates and a flood of cheap money despite record levels of consumer spending and a 30% surge in Chinese exports—all of which is straining against pandemic-constricted supply chains. Add to that Russia not flowing nearly as much gas into Europe as expected (perhaps as a passive-aggressive tactic to force approval of Nord Stream 2).
But the roots go deeper. The ESG and carbon divestment craze has so demonized fossil fuels (and nuclear power) that institutional investors and governments have cut them out of portfolios entirely, and have instead been flowing capital to more socially acceptable low-carbon alternatives.
[...]Let’s be clear. The planet is not in jeopardy. We are in jeopardy. We haven’t got the power to destroy the planet—or to save it. But we might have the power to save ourselves. — Ian Malcolm (Jurassic Park)
Are we, by ignoring, glossing over, deprioritizing climate change, committing mass suicide? — Agent Smith
https://theconversation.com/ancient-antarctic-ice-melt-caused-extreme-sea-level-rise-129-000-years-ago-and-it-could-happen-again-131495We found that the mass melting of the West Antarctic Ice Sheet was a major cause of high sea levels during a period known as the Last Interglacial (129,000-116,000 years ago). The extreme ice loss caused more than three metres of average global sea level rise – and worryingly, it took less than 2˚C of ocean warming for it to occur..
https://agu.confex.com/agu/fm21/meetingapp.cgi/Paper/978762The Thwaites Eastern Ice Shelf is the floating terminus of the Thwaites Glacier, one of the fastest changing glaciers in Antarctica and contributing as much as 4\% of global sea level rise today. This floating ice shelf is stabilized offshore by a marine shoal and acts as a dam to slow the flow of ice off the continent into the ocean. If this floating ice shelf breaks apart, the Thwaites Glacier will accelerate and its contribution to sea level rise will increase by as much as 25\%. Over the last several years, satellite radar imagery shows many new fractures opening up. Similar to a growing crack in the windshield of a car, a slowly growing crack means the windshield is weak and a small bump to the car might cause the windshield to suddenly break apart into hundreds of panes of glass. We have mapped out weaker and stronger areas of the ice shelf and suggest a “zig-zag” pathway the fractures might take through the ice, ultimately leading to break up of the shelf in as little as 5 years, which result in more ice flowing off the continent.
http://nsidc.org/greenland-today/Two near-record melt events occurred in the 2021 melt season for the Greenland Ice Sheet, in late July and in mid-August. During the second event, an unprecedented occurrence of rain at the National Science Foundation’s Summit Station took place, the first to be observed in the satellite era. Overall the melt season was unexceptional, owing to a modest start; however, the mid-August heat wave was both strikingly intense and late in the season by several weeks compared to similar events in the record.

1 human produces around 2 tons of CO2 per year. — Agent Smith
As the economy’s energy-starved productive sector atrophied, this corrosive catabolic sector metastasized rapidly. It profits from conflict, crime, and disaster; scarcity, hoarding, and speculation; isolation, desperation, and prejudice; fear, anger, and chaos. We can see catabolism at work in today’s fractured media landscape. Cable and Internet giants manipulate and monetize users. Their algorithms customize and sensationalize content, enticing us to keep clicking and scrolling. Curiosity draws us down rabbit holes that feed our anxieties and prejudices by marketing wild conspiracies, xenophobia, religious fanaticism, crackpot patriotism, and racial hostility. Weapons manufacturers are also well positioned to reap catabolic profits by selling expensive firepower to governments and small arms to terrorists, über patriots, white supremacists, drug gangs, criminals, and a fearful public. The catabolic contractions ahead will drive the demand for their lethal merchandise to record heights.
