It is probably too late with record high temperatures, every few years, for centuries to come.

It is probably too late with record high temperatures, every few years, for centuries to come.
- tejohnso 3y agoAnd maybe record high atmospheric CO2 concentration every few years as well. We're still on an increasing trajectory. The 2007 IPCC climate change synthesis report specified a deadline of 2015 for peak CO2 in order to meet the lowest mitigation scenario. Of course we've blown past that date and it's still full speed ahead with business as usual. Alas, I try not to blather on about the severity of the climate situation in every thread.
- midnitewarrior 3y agoI'm hopeful that superconductors leading to practical fusion reactors can provide the energy to start pulling some carbon out of the air and ocean. I'm thinking this is the only way to reverse the damage on the human timeframe. I admit it's a longshot, but I think it's the only chance we have. The superconductor news is welcome, we just need to see it get truly confirmed without a doubt.
- highwaylights 3y agoNot to be a bummer but by far the most likely outcome here is that we don’t currently have a room temperature super-conductor, we never pull a consequential amount of carbon out of the atmosphere, and we don’t get significantly workable sustainable fusion in a timeframe that makes a difference. You’d need a bunch of jackpots to come up, in a row, immediately, at this point for technology to provide a way out of the current debacle. To paraphrase Paul Lieberstein’s character on the Newsroom: If we stop drilling globally right this second AND Everyone stops driving their car and starts biking everywhere AND We invest immediately in clean renewable energy THEN I still don’t see a way out of this. edit: found it on YouTube https://m.youtube.com/watch?v=pNYp6oc37ds https://m.youtube.com/watch?v=pNYp6oc37ds

- Filligree 3y agoLots of us won’t.
- CamperBob2 3y agoDarwin will have his due, all right. Sad but true.
- influx 3y agoWhat’s your thoughts on nuclear power?
- darkclouds 3y agoWhat ever came about from the CRU hack [1]? I was walking my dog there most days when that happened, and to my knowledge they never caught the spooky hackers did they? For now, just call me spooky Patsy. Anyway, whilst more and more cars and buildings with air conditioning expel heat without a considerable lag, thus amplifying the thermal heat island effect [2], and the reduction of aerosols that were contributing to global dimming [3] making it possible to warm up the sea and land to new record highs since records began [4], have the climate scientists adjusted their models yet, or are they still in full on fatalism and alarmism mode?

- cyrillite 3y agoAt least room temperature superconductors will be easier to achieve if room temperature keeps rising :’)
- bedhead 3y agoNo group of people are literally more miserable than the conspiracy theory climate doomsday cult.
- pstuart 3y agoIf only we could live in a fantasy world where such a problem is just a "liberal conspiracy" to be mocked.
- hidelooktropic 3y ago"Conspiracy"? Who is theorized to be conspiring to create climate change?
- incrudible 3y agoBig oil, which surely must have paid off everyone who entertains the thought that perhaps we can not Just Stop Oil.
- BurningFrog 3y agoTemperatures can be lowered by pumping SO2 into the stratosphere. The effects are well understood. The practical details should be figured out in a decade or so. The political side may be harder. https://marginalrevolution.com/marginalrevolution/2023/07/superfreakonomics-on-geoengineering-revisited.html https://marginalrevolution.com/marginalrevolution/2023/07/su...
- SketchySeaBeast 3y ago> The effects are well understood. Are they all understood? Sure, it seems like a rational suggestion, and we know that if we add it to the atmosphere it should cool, but what other effects will it cause? How many times have we tried this trick where we introduce something new to an environment and it doesn't turn out like we'd like it to? Feels like we're hoping to apply a band-aid but not deal with the wound.
- luma 3y agoCool, then what practical solution do you propose? Wait around while things get worse?
- SketchySeaBeast 3y agoWell, that's not much of a rebuttal of concerns, and as I'm not in the field I don't have suggestions.
- BurningFrog 3y agoFirst of all, the SO2 goes into the stratosphere, not the atmosphere. We know a lot about it because volcanoes do this occasionally. Temperatures cool down for about 2 years, which is how long it takes for the S02 to break down.
- SketchySeaBeast 3y ago> First of all, the SO2 goes into the stratosphere, not the atmosphere. Considering that the stratosphere is part of the atmosphere, that's both pedantic and incorrect. > We know a lot about it because volcanoes do this occasionally. Temperatures cool down for about 2 years, which is how long it takes for the S02 to break down. Volcano's don't pump pure SO2. Yes, the science may be entirely valid, and it's not for me decide, but I think it warrants heavy consideration before we try to solve problems we're creating due to adding excess by adding additional excess.
