When methane clathrate dissociation caused the tempurature spike during Paleocene–Eocene Thermal Maximum the global mean temperature spike was like 2 degrees Celsius higher than before. I think humanity will survive the next thirty years just fine really.

>99%
>massive extinction of all marine life
None of the extinction events got more than about 50% of marine life. And this particular extinction was one of the smaller ones. Here are some highlights about what wikipedia has to say about it:
>The PETM is accompanied by a mass extinction of 35-50% of benthic foraminifera (especially in deeper waters) over the course of ~1,000 years – the group suffering more than during the dinosaur-slaying K-T extinction (e.g.,[27][28][29]). Contrarily, planktonic foraminifera diversified, and dinoflagellates bloomed. Success was also enjoyed by the mammals, who radiated extensively around this time.
>The increase in mammalian abundance is intriguing. There is no evidence of any increased extinction rate among the terrestrial biota. Increased CO2 levels may have promoted dwarfing[39][40] – which may have encouraged speciation. Many major mammalian orders – including the Artiodactyla, horses, and primates – appeared and spread around the globe 13,000 to 22,000 years after the initiation of the PETM.[39]

Ehh I may not be a scientist or some researcher or some shit but I can tell you this. This global warming cause by us is bullshit. The earth goes through cycles of hot and cold. Just as the seasons change so does temperature of the earth. No matter how much emissions we put out the earth will beat us in that race. Anyway I'd be more worried about yellowstone blowing up.

A lot of researchers think that the reasons for the natural variations of the climate are unable to explain the presently observed. It's not as if the climate just suddenly decides to change. Instead global climate change happens due to changes in external factors such as the sun's light dimming or the Earth's orbit taking on a more eccentric pattern. We can SEE when those factors are changing and how much they are.

That picture is pretty dumb. Why lay the blame on US presidents and equally across the different presidents. Even if you only laid the blame at the feet of the US, action in this case is hardly responsibility of the executive. I don't know what is up with that graph and even taking the most extreme IPCC scenario and combining it with a 0.6 degree rise from the clathrate gun we wont see extermination by 2030.

Climate change is a very real thing and nothing fucks me off more than people unnecessarily saying that it is going to be worse than what the science says. The interview is good if you pay attention to exactly what he says. The way he responds is essentially that 50 gt is an approximate upper limit, he acknowledges that his model was run on this upper limit and gives 0.6 degree. when he answers the survival question his answer is basically global warming is really bad and this adds to it which I think everyone can agree with. However beware if there is one thing that is going to stop action on climate change it will be people lying about the severity and then when nothing super extreme happens the action will stop. If you don't believe me read some of the most common criticisms, there is a lot of "time said in 1970s..." and "we were told we would all be underwater by now" and the only people we have to blame for this are the retarded advocates who overstated there cases without knowing the science.

Except even vat-grown cockroach burgers will only feed a few million because of how much energy it needs to make them. Have you seen the energy requirements to grow food? The reason old school farms work so well is they take energy from the sun and the rest of the ecosystem, which is basically free. Our modern farms already use a huge amount of oil to try and increase yield, look at the energy in that it is huge. If you had to get that amount of energy from a power plant you would need to seriously consider how the other 99% of our population is going to adapt to break the laws of thermodynamics. And don't tell me 99% of humanity starvings to death wouldn't have a huge effect that couldn't trigger a few wars and shit which stand good odds of finish us off.

There is nothing really to debunk, because we don't have the differential equations nicely solved and we may never will, however, the most intense GHG is water vapour. The presence of which varies dramatically through years, furthermore, there is also a positive feedback loop in terms of, "the warmer it is the more water vapour there can be present in the air", and the more water vapour there is the warmer it will get, yet somehow, not one event triggered this not a volcano eruption, or a flood, or a meteor, no nothing.
Thre's a lot of way to turn rhetoric into nasty predictions...

Nothing to see here people, just another batch of alamists, doomsayers and environmentalists promising "death in our lifetime!"

The clathrate gun hypothesis is just that, a hypothesis. To trigger a mass methane spike we'd need an initial warming spike far exceeding any reasonable projection and even so the methane release spike would resemble a rolling landscape moer than a spike from human timescales.

This

2 degree rise is massive for animals and plants because they can't just magically decide to move to a different part of the continent in a matter of years.

Humans have farming on pretty much everywhere but poles, 2 degree warming will make food supply dwindle in the hot regions but colder regions enjoy nice benefits and since humans can choose what to plant and use seeds designed for that particular environment or even genetically modify existing species to tolerate hotter temperatures better.
There is absolutely no extinction level or even civilization ending threat to food supply or anything really coming from global warming unless it starts to close the point of no return where oceans start to boil and Earth turns into Venus like planet.

Sure things will get really shitty for poor people and countries but rich northern countries will do just fine so long as they are willing to mow down the climate refugees coming from southern countries, Namely this means Africans for central Europe and Mexicans for US

Much greater threat to human civilization is nuclear war or even immigration if you look at how Britain and Sweden are doing.

No, but you need a lot more then sunlight to grow good plants. That is what the ecosystem helps bring in, animals mix in minerals that allow plants to grow better and have more nutritional value we need to live. You want to try and refine and mix that artificially you are going to need a lot of energy. In fact it takes so much effort that we stopped trying to do that on a large scale.

then you got to deal with other issues like >>7235981

add this and other things add up, so you aren't going to feed more then a few million without some kind of game changing breakthrough the likes of which I can't even think of as you run into physical limitations that money and tech can't solve.

Plants growth is limited by cold weather and dry climate primarily. Plants still grow in hot weather provided the water is there.

So unless the hot weather evaporates lakes and other freshwater sources we'd get a positive net total in agricultural land, perhaps even much more as the sea-evaporation rain cycle would be more active and could in fact increase efficiency of hot-climate agriculture.

If the Clathrate gun hypothesis comes to pass, here's how it could really help humanity:
1. It will then become cost effective to remove CH4 from the atmosphere.
2. CH4 as an energy storage medium is very attractive compared to Hydrogen fuel cells.
3. Compared to other hydrocarbon fuels, burning methane produces less carbon dioxide for each unit of heat released.
...
So when can we expect this to happen, so we can tap this wonderful new resource and solve the worlds energy crisis?
