...back on topic, 95% of cattle methane is from their mouth, not their rump...
Scientists breathalyze cows to measure methane emissions

Average bovine is estimated to put out about 0.5 lbs of methane daily...
Livestock Methane Emissions in the United States

So if we can capture the methane and burn it as fuel...

So if we can capture the methane and burn it as fuel...

More likely is we can engineer the gut microbiome of the live stocks to reduce the output of methane.

https://link.springer.com/article/10.1007/s00248-018-1234-9

Altering the gut microbiome of a cow is a lot easier and humane than genetically editing a cow. Plus those gut microbes won't make to our dinner plate so it is also easier for the general public to accept. My current lab had some old collaborations that looked into establishing a healtheir microbial composition for livestock to achieve both lower methane output as well as higher diet-->protein conversion rate.

Microbes are truly amazing creatures. They are the main inhabitant of the deep surface biosphere. They are THE major reservoir of earth's biologically available Carbon pool. These microbes can soak up more GHG than any thing we human has ever come up with.

Didn't read it?

University of Washington ice scientist Ian Joughin, who wasn’t part of the study and predicted such a change seven years ago, said it would be a “grave mistake” to interpret the latest data as contradicting climate change science.

What’s happening, Joughin said, is “to a large extent, a temporary blip. Downturns do occur in the stock market, but overall the long term trajectory is up. This is really the same thing.”

Weather (including solar) impacts the short term but long term trends make climate. The oceans are holding more energy than they did previously and that influences climate in the direction of warming. On the other hands, the scale of the oceans cause them to be mediators rather than quickly reactive like weather.

 

[R-T-B]

Also keep in mind that Chinese have very little individual freedoms and Xi Jinping (whom you praised) has been crushing what little they have gained under Hu Jintao and Jiang Zemin.

Yes, I agree with you for once Ford. However for the same reason I highly doubt strategic waste is going to pose much of an issue (to leadership).

Don't let science detract from rhetoric ford. That'd suck the will to post out of the uneducated masses.

I mean, it always has been to anyone with half a care into the issue.

 

[FordGT90Concept]

You're right. If Communist Party says there will be a strategic waste facility in a specific location, there will be a strategic waste facility there. It's not like Yucca mountain where you get enough protestors and lawsuits then the idea falls through.

My point was more that China's nuclear program hasn't been challenged yet. They haven't had a level 7 disaster like Chernobyl, Three Mile Island, nor Fukashima. If they have a disaster, the Communist Party may not be able to keep the NIMBY factor in check.

I could care less either way to be honest, humans are a mistake of evolution from my observations.

I don't agree. We are what nature's best offer thanks to billions years of evolution. We as a species need to keep growing and evolving.

Homo floresiensis = Failure extinct
Homo neanderthalensis = Failure extinct
Homo heidelbergensis = Failure extinct
Homo ergaster = Failure extinct
Homo Simpsonis = Failure extinct
Homo sapiens = Success ( under Review ) not extinct

So Far the failure's of the past have contributed to our current status of successful (under review)

still don't care, all depends on your understanding of time. all species go eventually. its a wonderful cycle. i mean technically we have only had civilisation for 10k years... that's like nothing.

Pretty sure the only reason other species of humans haven't survived is due to the proliferation of Homo Sapiens.
To cite a line or two from a movie: Mankind is - "A virus. Human beings are a disease, a cancer of this planet."
That doesn't mean the other types you mentioned are failures, just that they were overrun by sheer numbers alone, and failed to survive .

 

[R-T-B]

I don't agree. We are what nature's best offer thanks to billions years of evolution. We as a species need to keep growing and evolving.

We aren't even the most populous species. Nor the longest enduring... It's easy to be number one when you pick the gauge I know, but I'd say that's highly disputable. Personally (and in no way tied into my frog persona I assure you) I think we have a lot we can learn from other species, both in genetic tech and general intelligence.

When Sapiens and Neanderthals co-existed, both were nomadic.
http://humanorigins.si.edu/evidence/human-fossils/species/homo-neanderthalensis

In fact, Neanderthals and modern humans may have had little direct interaction for tens of thousands of years until during one very cold period, modern humans spread across Europe. Their presence may have prevented Neanderthals from expanding back into areas they once favored and served as a catalyst for the Neanderthal’s impending extinction. Over just a few thousand years after modern humans moved into Europe, Neanderthal numbers dwindled to the point of extinction. All traces of Neanderthals disappeared by about 40,000 years ago. The most recently dated Neanderthal fossils come from western Europe, which was likely where the last population of this early human species existed.

Back on topic: Untangling Methane Sources

Based on data from five days’ worth of measurements in 2015, the team found oil and natural gas operations were responsible for most of the methane produced in the Denver-Julesburg Basin, with agricultural sources providing an important but minor source.

The study also uncovered some baffling observations that will require further exploration: for example, when methane concentrations are very low, the agricultural sources are relatively more significant.

Scientists amazed as Canadian permafrost thaws 70 years early

Permafrost at outposts in the Canadian Arctic is thawing 70 years earlier than predicted, an expedition has discovered, in the latest sign that the global climate crisis is accelerating even faster than scientists had feared.

I think global warming is real, I think it's caused by humans, and it's accelerating.

Photo of sled dogs walking through water shows reality of Greenland's melting ice sheet - CNN

Steffen Olsen, a scientist with the Danish Meteorological Institute, was on a routine mission in northwest Greenland to retrieve oceanographic and weather monitoring tools placed by his colleagues on sea ice when he ran into a problem.

www.cnn.com

I also think sled dogs will have to learn to swim if they want to keep their jobs.

Climate is complex, but change is real; it been happening longer than we've been alive; my climate, where I live, it very different than it was 40 yeas ago.
Ask your parents what the weather was like when they were kids.

Just because a politician tell you something doesn't make it true; they will be long dead before it's a problem.

Probably.

From what ive learned the ice-age is a natural, and due to come anyway.
And no matter wut, im not use to snow midsummer in denmark, nor our ice looks like this in greenland, enviroment is changing fast.
Here u can see the hot summer melted the upper part of the ice.

@Eskimonster While I agree climate change is natural even at massive levels at least every few hundred thousand years, it doesn't change the fact 70% of all humans live in coastal cities, and we are in for mass displacement and mass starvation in the billions by around 2050 or 2060. Probably sooner honestly. Technically speaking, Syria had a civil war because of crops and farmland becoming unusable do to climate changes, and that tiny little country has brought the West to its knees from refugees and political turmoil. NASA astronaut Mark Kelly also said when he lived his year in space the thing that scared him most was how sickly the atmosphere was looking over time...

We know not what we do. Natural or man made, it no longer matters, majority of humans, well those not smart enough to learn self sufficiency and move inland, will perish and so will their genetic lines, not to mention as heat waves become more extreme, heat is directly related to violence and past genocides in Africa. Irrational incidents will occur, eventually escalating to all out wars, and not baby wars like the middle east, a proper number 3 this time sadly.

We have a good 20 years left I think before things become shaky in the world. If you are aged 20 now, I wouldn't bother with retirement savings, money will be worthless by 2070 lol

Major Climate Change may occur every 10 millennia or so but
Minor Climate Change can happen over 2 to 3 hundred years or even less time
Europe and North America had a little ice age after the late Medieval Warm Period ( 1300 and 1870 ).
This Era ended as the Industrial Revolution was getting into full swing ( Coincidence ?).
On an even shorter time frame El Niño and La Niña. Both have a global effect ( this is weather tho and not climate change ).

El Nino and La Nina are both products of the 90s. There was no satellite evidence of these phenomena before that. We are in the middle of the biggest climate change episode in recorded human history. I live in the Toronto area and cannot tell you the last time the temps have not changed by more than 3 degrees C in 24 hours. There are so many other manifestations of what we are doing to our planet too. One of the things that not a lot of people talk about is water vapour. When an iceberg or glacier melts it also adds to the water vapour levels in our atmosphere. There are a few things that support this.

1. In 2018 there were 3 hurricanes in the Atlantic basin at the same time.
2. By the time Hurricane Sandy made landfall it was 1200 miles in width (The largest hurricane before in the Atlantic basin was 300).
3. The type of rain in Toronto nowadays reminds of the rain you get off the Gulf of Mexico in Mississippi.
4. The jet stream is more heavily influenced by Arctic flows than ever before. (As proven by the polar vortex) Ask anyone that lives in England how their winters have changed in the last 20 years.

Right now these are seen as separate incidents but they all point back to water vapour. Australia got hit by 2 hurricanes at the same time this year. Africa has also been hit by 2 hurricanes this year. 70% of the State of Nebraska was flooded earlier this year. The evidence is there all we have to do is look.

For the simpleminded, check out this easy to understand graphic:

Ironic that someone claiming such a simple graphic is sufficient would call others simple minded...

Regardless, that graph starts at 20k years ago. Zoom that graph out further (and get rid of biased "smoothing" techniques... look up Bradley, Mann, and Hughes sometime...) and you'll see that the earth was FAR warmer millions of years before humans even existed to add CO2 to the atmosphere. Moreover, you'll see that CO2 levels in the atmosphere lag BEHIND temperature rises, suggesting that it's more likely that rising temperatures cause higher CO2 levels, not the other way around. The truth is, it's nearly 5 degrees cooler even today than it was around 50 million years ago, and there were no humans around to cause that. Now, we're worried about a less than 1 degree uptick?

This "simple graphic" mindset is the problem. I've posted the information back in this thread (a couple of times, if I'm not mistaken) along with links to raw data. If you'd rather follow a simple graphic than wade through it yourself, I understand why you'd come to such conclusions... you're doing exactly what you claim others are doing. I find it hilarious also that you'd say something about politicians, considering they're the ones pushing this alarmism. It's ridiculous to think that a two degree uptick is going to end the world when the world existed just fine at 5 degrees warmer, AND at 5 degrees cooler, than we have now, before humans even evolved. Hubris it is, to think that we're so special...

From what ive learned the ice-age is a natural, and due to come anyway.

Yes, it's due, and nobody knows what causes it. It's something that started about 3M years ago, and has steadily gotten worse. If we can do something to to avoid it or lessen it's severity that will be a major win. Last time all of northern Europe, all of Canada, and a good chunk of the northern US were under a massive ice sheet. And people think a little sea level rise will be devastating! On the plus side higher temperatures will make huge swaths of northern Canada and Russia livable. Global warming isn't all bad, and may be highly preferable to the alternative.
