Oops, convo moved on during my editing. One Eyed Jack, I edited my answer to your question on methane into the post up above there.

Edit (again)
Aha, a clearer bunch of estimates:
Fossil Fuels - 110million tons/yr.
Livestock - 90m/t
Landfill and Waste - 55m/t
Biomass - 38m/t
Rice paddies - 31m/t
Biofuals - 12m/t

Natural Sources
Wetlands - 147m/t
Termites (yep!) - 23m/t
Oceans - 19m/t

Edit: Done some checking up of old notes and the IPCC reports.

Rightie, animal methane emissions are a moderate part of it. CH4 emissions prior to the Industrial Age (1750 is the general approximate date) were about 200-250Tg(CH4)/yr (teragram = 10 to the power of 12 grams/1 trillion grams). Of this, anthropogenic emissions were only about 30-60Tg, taking the widest ranges. (AR4)

Presently, total emissions are averaging at about 582Tg (CH4)/yr (Fifth Assessment report), although there is a wide uncertainty range. Bear in mind that methane does vary quite strongly naturally over time. At the moment, we do have a far higher base figure though. We can probably go with 582Tg. Of that, most is down to land use, which is anthropogenic. Coal mining, fossil fuel industry, landfills/waste, biomass burning, rice paddies (a big one) and ruminents are all anthropogenic. Natural sources include wetlands, the ocean's steady release (which can also be increased by warming) and geological sources.

Approximately a quarter (varying a bit by country) of methane emissions are down to intense stock farming, including all ruminants. This isn't just cows farting though, it's also down to their waste and decomposition/burning thereof.

It is -an- important greenhouse gas, but it is still behind CO2.

Cheers for that Samaris, I had read before about the effects of intense farming and deforestation in Brazil years ago was contributing to climate change, along with the the Industrial and Agricultural revolution in the Western World, but the paddy fields one surprised me alright!

But it's precisely because of blatantly ridiculous predictions like the one at the top of this thread, that make rational people skeptical if the entire thing.

Love your optimism but we've already had two huge incidents with nuclear power and it's only been around 60 or so years.

Nuclear power isn't the same argument as nuclear war. And it's largely safe. In fact it may be one of the solutions to climate change.

In general the number of wars and conflicts has been diminishing over the last 50 years. If the U.S. wasn't do extraordinary belligerent post cold war it would be better, of course.

I'm pretty sure if you compared nuclear power to any of the other major providers of power the deaths per kilowatt would be much lower than you'd think. Even Chernobyl hasn't had quite the negative effect people were expecting.

It is costly to deal with nuclear power fallout, but its legacy power plants that are the result of a cold nuclear war that are the problem, there are designs for alternative cleaner power plants out there that we could use.

True. You can also factor in the huge rate of morbidity from smog and combustion, but of course, it's very difficult to get a precise number.

The major issue with nuclear energy is just what to do with the waste. It IS much less waste than from coal and oil, but it's toxic and survives a hell of a long time. There is also the fear issues - very few people really -want-to live near a nuclear power plant. There are always "what ifs" floating around. Not to mention the fear of their being terrorist targets.

Nuclear power is cleaner and more efficient than fossil fuels, especially compared to shale/fracking, but it does have a very bad reputation.

Samaris · 19-06-2015 9:46pm

One thing that you can say for scientists is that they DO have accountability. The peer review process is tough. Things can be proven -wrong-, and discredited by repeated examination and/or testing. That is the natural way of things. Nothing is ever considered absolute, but eventually by consensus (evidence-driven, not opinion-driven), a general idea is founded and expanded upon by further investigation, building on the repeatedly tested work of others.

Just sometimes you get monumental eff-ups, but again, they tend to be noted by the rest of the community if the journal fails to do peer-review (which is why it's important to check your journal!)

Nothing's perfect, but peer review is one of the better ways so far.

Alright, I -am- a climate scientist and while it's nice for once to see it working the other way, this is -not helpful-.

Firstly, he is NOT one of the "world's top scientists", he's an engineer and a science writer. The previous chap that said it is a microbiologist, aka. a "false expert". If I said "I am a scientist and evolution means we will transform into salamanders in 1,000 years", I would still be a "false expert" because I'm not properly trained in the right field.

Yes, climate change is happening, and yes, the only explanation that holds water is that it is anthropogenic in nature. And yes, even if we cut all emissions of CO2 and methane, etc, into the atmosphere right now, we would -still- be on a route to significant and semi-permanent change, since we do see a significant lag in effects.

What we can expect to see is a continuation of sea level rise, probably topping out at about a meter by 2100. This is due to what's called thermal expansion for the most part (water gets bigger when it's warmer - you can see it in action by boiling a kettle ^^) as well as ice melt from land glaciers, such as Greenland.

We can also expect to see a steady increase in extreme hot events and fewer extreme cold events - over Australia in the last fifty years, we see an increase from approximately 1:1 hot:cold events now more like 5:1 hot:cold.

We can expect to see more rogue events - big storms, etc. All of these will have a certain mortality rate, but we will adapt. Certain small island nations may indeed vanish, and their populations have to move elsewhere - that's already going on in two of them, but don't ask me for the names because I can never recall offhand.

Overpopulation isn't entirely a thing, or rather, it IS, but we can probably expect to see a gradual flatlining of the world population, topping out at about 11b. If you look at Japan, they have already hit the Stage IV population status.

Overuse of natural resources is definitely alarming, and we should be doing our best to conserve them. If we don't, we could indeed see a reduction in our quality of life, not to mention what we are doing to our children and grandchildren.

But relax, we're not all on the edge of extinction :P

/thread could have closed after that methinks.
Thank's Samaris.

This world is a beautiful, incredible place, and the journey its taken from about 4,540MY to get to here, to a point in time where it's sheltered us through our rise from apes is just amazing. I've recently been reading up on the beginnings of the solar system and all these freak chances (or if you're a religious type - godly intervention!) are just incredible.

It would be a dreadful shame to screw it up in the space of a couple of hundred years! Really, it's since the Industrial Revolution that we're really starting to see the effects. We are an extremely clever and adaptive species, but we are also tribalistic and inclined only to consider what's right in front of us and affecting us and those closest to us. We don't think well in the long-term, yet as one of the few species with that capacity, we should use it!

TheLastMohican · 20-06-2015 12:45am

In the life of the Universe - this has happened maybe a million times. Hot cold. Cold hot. We just live here. Just the same as the huge animals of yore. Did their emanation of methane contribute to mass extinctions in the past? We are but beads of sweat in the armpit of the great frog. Peace!

Couldn't agree more. Cowboy Capitalism and greed mainly I believe are at the heart of the reasons for the mess we've made of our beautiful planet.

Yes the ideas on how the solar system came into being are very interesting. Not a scientist (and no, not a godly type at all either) but have massive respect for science and the scientific method and was watching a video recently of an interview with the renowned Mathematical Physicist Edward Witten on string theory and M-theory and the origins of the universe. Fascinating stuff.

Whatever about the debate re climate change and its causes i see it simply as this...

we are brainy enough to be able to run our mother ship on RENEWABLE resources,( and brainy enough to be able to produce enough resources to comfortably tend the needs of all our fellow cosmonauts) and yet... we insist on draining the mother ship of non-renewable resources (and keeping fellow crew in the dankest vaults). So, the question is why do we use non renewable resources? I reckon it is not so much about our inability to think long term. many of us are quite capable of that, thanks....but follow the money trail. The wealthiest people on our mother ship are invested up to the oxters in oil. They are in charge of the bridge

I don't think that's true and that article seems to take some liberties with some facts. Like how he blames the people of easter Island for deforesting their island when that's been shown to not be the case.

The human brain has often been called a prediction machine. It's constantly running it's own internal simulations. We always contemplate what consequences our actions will have. There's proof all over the place that humans are constantly thinking about the future, just look at the pyramids, look at any medieval church, people would have known when they started that they probably wouldn't see it finished.

The problem with climate change is that it's an issue on a scale that we've never had to deal with before, it's global. It's one thing to realise the problem but it's another thing entirely to get societies thousands of miles away from each other to compromise. Especially when the developed nations try telling the developing nations not to do all the things that made them developed nations.

KomradeBishop · 23-06-2015 10:46am

Well, even people who understand the long-term unsustainability of climate change, tend to have zero understanding that it is caused by long-term unsustainability of our economic system itself (particularly the monetary system) - people have been blind to that for a very long time, and it's something that triggers pretty massive cognitive dissonance in people (people vary between either not wanting to know, or finding a myriad of lame excuses to justify the current system).

With the pyramids or any large construction project, the problem is tangible and immediately visible, but with something like climate change or the unsustainability of economic systems, the problem is more abstract and not directly visible - and this seems to make it almost impossible for a lot of people to even comprehend such topics.

Solving climate change doesn't require co-ordination worldwide - one country, such as the US, could engage in a New Deal type project to completely revamp the countries infrastructure, and a Manhatten-Project style technological research effort to develop new energy technologies that the whole world can benefit from.

Countries can start this now individually, but the problem is economic ideology: Fighting climate change directly requires big government spending, which is what the current dominant economic ideology opposes completely.
