I've thought for decades that when methane hydrates start to melt in large quantities our ability to do anything meaningful is gone.

That cycle seems to be in full effect and accelerating at the same time we are also accelerating our greenhouse gas emissions.
I think the short and long term situation is worse than even recent reports suggest.

Not so much if you actually read (and comprehend) it, or listened to the authors.
They've said clearly that even using their revised estimates of CO2's effects that to meet a 1.5 degree rise (the tipping point where we loose all ability to mitigate the run away greenhouse effect and start the irreversible march towards mirroring Venus) we have to start decreasing CO2 emissions today and be at zero by 2040. They've also said clearly that anyone misusing their paper to imply climate change is a myth is a liar, a moron, or both, because it says and implies no such thing.

What we are doing is raising the amount we emit while people like you who clearly don't grasp the science argue, ignoring that the effects of warming are already being seen far earlier than predicted....effects like melting methane hydrates that make up the difference in CO2 effects and then some, effects like 3-500 year floods in under 2 years in places, effects like reefs bleaching worldwide.
So much for the climate science denier BS.

It likely is too late, as soon as these short-lived but potent gases are released it will get unpleasant very quickly. I know dumping iron in the ocean to stimulate algae growth which then sinks as acts as a carbon sink has been discussed. Also, spraying aerosols into the upper atmosphere constantly can decrease warming, but that doesn't reduce the CO2.

It's like the doctors have given you second and third opinions and told you your liver is failing, you have to stop drinking or you'll die. You won't die the next time you have a beer, but every beer takes you farther over the edge. You can say the bartender who knows this is blameless for serving you, because others gave you the alcohol that destroyed your liver and it took longer than one night, or you can work from now and realize that he's intentionally killing you in hopes of a tip before you stumble outside and keel over.
Working from today, our planet's liver is failing, there no transplant, and Trump just reopened the bar and is serving everclear. Chances are he can't accelerate things so much that Florida submerges in the next 3 1/2 years, that doesn't mean he can't make things be far worse, beyond the point of possible mitigation.

You may hold that theory, but climatologists disagree. We are past, but still near the tipping point, and every ton of CO2 takes us farther from a survivable rise. It's ridiculous to think that we're already past holding at 3.5 degrees global rise (edit: the maximum assumed to be survivable by civilization), so we might as well make it 5 degrees.

Island nations, people who live South of New Orleans, and millions of others are already being displaced. It only takes one high tide (edit: or one extended drought) to wipe out low lying farmland permanently, and erosion has become an unstoppable force.

Trump is moving towards raising the level of multiple greenhouse gases we produce, Obama had us lowering those levels. Time can only tell what that actually means in tonnage, but 180 degree turnaround is awful enough. I agree, we also didn't do enough under Obama.

? Reversible means it can be reversed, not that it's easy. I don't know where you get that idea. Irreversible in this context means sending the temperature trend the other way before civilization becomes unsustainable. Eventually the planet should normalize unless we really follow Trump's lead wholeheartedly, then we might go full Venus. There WAS a magic bullet, being responsible with our atmosphere, but we argued over climate change until it was useless.

If, before it reverses (which it may not do at all, btw) the planet becomes inhospitable to humans, then for humans, it's irreversible. In 4 years we can do enough damage to 1) make the effects longer and harsher enough to make long term survivability impossible and or 2) go beyond the next tipping point where feedback loops reinforce each other, leading to a Venus like runaway greenhouse effect. We're damn close to massive methane releases (already happening) and if we don't avoid that, nothing will save civilization.
All that said, Clinton probably wouldn't do enough to avoid disaster either, but at least she accepted the science and agreed we should make efforts to mitigate the coming damages.

I'm definitely a pessimist, mostly because I understand the systems and human nature, and so I think we're totally hosed as a species.

The problem is the actual live stock themselves. There are over 80 billion of them burping and farting methane as they grow each and every year. Methane traps 2500 percent more heat than c02. The other problem is land, water use, pollution etc (feces from 80 billion animals doesnt play well with the eco system).Tranport is a small fraction of the problem. Look up cowspiracy.com/facts

@coolhund @JustSaying

Not just CO2 production. Also use of fresh water resources. Polluted water from feces collection (and yes, conventional agriculture is polluting water with chemical runoff.) In places, the cutting down of rain forest to create areas for beef production. The huge overhang of methane over New Zealand from all the farting sheep (that would be part of the CO2 mentioned. But I can't pass up the opportunity to actually type "farting sheep.")

"Beautiful creatures" are in danger. Not just these.

And I do eat meat. And drive my car. And am a hypocrite.

I agree that the tech exists, but to implement enough of that tech (in the time left) to change how humanity abuses our resources would take more resources than exist, leaving the tech swap 2/3 finished and the planet barren.....if you could convince everyone to go along.
Had we started moving in that direction 35+ years ago, maybe, but at this point the greenhouse gasses already in the atmosphere will cause climate change that's already decimated the forests and will continue to get worse, even if we go 100% green today. It's too late for tech, population control, or much else.....and the methane is just starting to be a factor.
If we just moved into the forests and abandoned tech, the forests wouldn't last one year.
If we eradicate 9/10 of the population, we don't have to change so much and the planet can absorb our damages without destroying the systems life relies on, then we just need to mitigate the damage already done instead of continuing to add to it. The best way imo was as you suggest, have people get fixed and quit having children the planet can't support...but it's too late for that even if we cut 3.2 billion nutsacks today. As I see it, we need to be fully invested in numerous plans to both stop making things worse (population, food issues, climate change, pollution, etc) and make some painful sacrifices to repair the damage done by the "greatest generation" and their spawn.

Because I'm broken, so I have free time but no real physical capabilities, and because I don't think most of the world deserves or wants my help.

I did my good here at home, where being a good citizen starts. I grow much of my own food at home using poo, not artificial fertilizers, I make my own electricity (mostly, by solar), and most important of all, I got fixed without having children. That's far more good for the world than 99.99% of people can be expected to do in their lifetimes, so I'm waiting for the rest of you to catch up. ;-)
Besides, I'm of the opinion that it's all over at this point, that global warming is far beyond solvable at this point, not that humans are trying. I firmly believe that land, water, and food shortages are in the near future for most people, so all these little arguments are moot. The animals have less of a chance than man, and man has no chance. The methane is melting, in my eyes that's game over, out of time. It's time to party like it's 1999.

If you read my other reply two posts up, it's clear that I'm not left leaning.

Your linked slaughter statistics are for the USA alone, and as far as I know GLOBAL warming affects the whole globe....so we should count the global amount of farmed animals.

Your statistics also only count slaughtered animals, and not farmed animals like dairy cows, which there are more of at any one time. Around 9 billion dairy cows in the USA. So already in the US alone we have 13.9 billion farmed animals(4.9b slaughtered + 9b dairy cows). It's not hard to see worldwide that figure reaching 50 billion.
And that's still not counting a bunch of animals (read the small print of your link).

The thing with methane too, it traps over 29 times more heat that co2....and most trees don't absorb methane. So even if we had enough trees to absorb co2 (which we don't) then all of methane from farmed animals would remain up there anyway.


80% of tree's aren't gone, 80 % of forests are gone:
https://www.google.com.au/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=how%20much%20of%20the%20world%27s%20forests%20have%20been%20destroyed


How much renewable energy tax do you pay BTW? Where I live I pay $0. But the government does give some $4 billion of our tax money to the coal industry. So if anything the big tax scheme is from non-renewable.


EDIT:
Oh I forgot the most important bit. Scientists can tell between natural co2 and man-made co2. They have differing amounts of carbon. So it's actually really easy to tell between how much carbon dioxide humans have put into the atmosphere vs naturally occurring carbon dioxide.


Also lions and bears are going to live in nature regardless of human activity - we've added 50 billion large, methane producing animals to the world that wouldn't be there otherwise. Granted the destruction of habitats might have reduced the lion and bear populations, but not by 50 billion. Perhaps a few million at most.

Are you sure that 50 billion farm animals releasing methane would have no affect on the planet?

Are you sure that cutting down 80% of forests (trees absorb co2) would not have an effect?

You don't need know anything about maths or science to see that these huge numbers are significant regardless of what the sun is doing.

Just to make sure you can appreciate how much 50 billion is - it would take you 31 years to count 50 billion.

Human activity in the last 100 years (especially in the last 50) has drastically changed the earth.

But....we already do that.
Pollution; soot, sulfur, etc, already cause global dimming, which is exactly what you're describing, blocking 10% or more of sunlight and mitigating as much as 5%, but averaging 2-3% of warming already. I have said repeatedly that instantly switching to real clean energy would actually accelerate global warming exponentially because of this little known effect. That makes most plans to do something actually worse than doing nothing in the short term, and now in the long term too because that rapid temperature rise would absolutely accelerate methane releases (among other cycles) which starts feedback loops, possibly turning us into Venus.
Sadly, because of the size of the areas where the methane is escaping, there's no way possible to capture it. You would have to cover about 1/5 of earth with a sealed plastic sheet or something. It's not possible to tap the deposits and siphon them off, they are not centralized gas pockets for the most part.

There have been some interesting suggestions to solving the methane hydrate issue, but the none are very realistic. The closest thing to a possible plan would be that we introduce particulate, natural or man made, into the atmosphere to partially block the solar heating cycle. That would seal the methane back into the permafrost and give us time to try to reverse the effects of climate change or find another method of neutralizing it.

That is the main issue. We don't have a way to remove the methane safely. Basically the situation is primed, we have a methane bubble that is going to happen at some point, there is no stopping that without removing the methane deposits in a safe fashion.
