Ilissa Ocko: The fastest way to slow climate change now | TED Countdown
“Cutting methane is the single fastest, most effective opportunity to reduce climate change risks in the near term,” says atmospheric scientist Ilissa Ocko. That’s because, unlike carbon dioxide, methane’s warming power doesn’t come from a gradual buildup over time but is almost entirely from recent emissions. Ocko identifies three main sources of methane pollution which,…

Summary of tge video: Cut methane emissions. No actual examples of methods, no data and no evidence.
Feels like a 13-year-old trying to write an educational essay, oversimplified and sometimes over exaggerated. It’s very difficult to address an issue so complicated with so less time. Could’ve made the entire talk into a 5 minutes slideshow video and save the energy comsumed for hosting such event.

January 15, 2022 at 7:27 pm
By your own words, Methane emissions are a problem the United States and Europe have by far the least amount of control over or ability to mitigate. The largest methane producers are rice growing, agricultural countries, countries that process a lot of natural gas and poorer industrial countries with lax environmental standards and limited resources to try any of the mitigation projects mentioned here. You can lecture China, India, Vietnam, Indonesia, Brazil etc all you want but odds are they’re going to keep doing what they’re doing for a long time before they change their behavior. This does illustrate that electric cars, solar panels and wind farms are not gonna get the job done in tackling climate change.
Lorenzo Blum
January 15, 2022 at 8:34 pm
According to Investopedia :
The U.S. is the top producing country of natural gas in the world, followed by Russia, Iran, Qatar, China and Canada.
The top ten natural gas companies in the world are from the U.S, Russia, Saudi Arabia, Netherlands, China, the UK and France.
Btw, the carbon footprint of the military industrial complex anybody?
Steven Hill
January 15, 2022 at 8:53 pm
“”This does illustrate that electric cars, solar panels and wind farms are not gonna get the job done in tackling climate change””
The scientist mentioned methane is released “extracting oil, gas and coal.” Gas cars run on oil so electric cars are clearly part of the solution
Lorenzo Blum

@Steven Hill only ETHICS can get the job done. Btw, the carbon footprint of the military industrial complex Steven?
Nathan Hearn
January 15, 2022 at 10:55 pm
@Steven Hill Respectfully, Solar and Wind power are intermittent power supplies – meaning you need a backup power source for when the sun isn’t shining/wind isn’t blowing. That backup power source is almost always a natural gas generator – so in essence, solar and wind ARE natural gas power sources. As for EV’s their shortcomings for powering larger vehicles means at best they can replace the ICE passenger car fleets but heavy polluting larger trucks, aircraft and ships will continue to run on oil or maybe gas. All of this says nothing about how and where these products are made and what they are made out of. These are realities that need to be confronted.

Sydney D'Argenio
January 15, 2022 at 7:48 pm
no no no…with regards to the agriculture portion: we don’t cut methane emissions by improving livestock feed. We must stop eating animals and animal products. Animal agriculture is horrendous for a number of environmental reasons that go far beyond methane emissions. That includes deforestation, water pollution and ocean dead zones, excessive water usage, species extinction. And this doesn’t even touch upon animal rights, to live lives free from suffering. Her point spreads the wrong message. Not everyone will go vegan overnight, or in five years, but the more we shrink the industry, the sooner it will collapse.

The only problem, they don’t kill enough.
Lorenzo Blum

@NoWhacko overpopulation is a myth. The real problem is everyone doing the same thing at the same time in the same place. The military is very good at that. And at brainwashing too obviously. If you enjoy being a puppet after all it is your choice but killing will not bring you happiness. Even if you have been indoctrinated to do so you might enjoy killing for a while but at some point you will get the PTSD.

January 15, 2022 at 9:24 pm
It’s impressive how many environmentalists when addressing cutting methane from agriculture don’t even consider the possibility to reduce meat consumption rather than creating advanced technologies to change the cow’s fart or cover the manure. The solution is simpler than that, just create policies to reduce meat consumption, such as over-taxation and so on
Stéphane Champon
January 15, 2022 at 9:58 pm
Or just stop subsidizing it !
ARRW
January 15, 2022 at 10:04 pm
Yep. That’s true. Though, I’m not sure over-taxation is the answer. California has the highest gas rates in the country due to over taxation aimed to make people drive less while gaining money for the state to fix roads. It failed to make people drive less, and just proved to make it more difficult for poor people to drive to work. The problem is, people don’t want to change their behaviors. We want the world to stop getting hotter and being destroyed by this stuff, but very few are willing to stop eating meat, stop drinking milk, stop driving their car, stop getting amazon delivered ridiculously quickly, stop heating and cooling down their home, etc. I don’t think major change will come without major upheaval of something many have come accustomed to. Although, the blame doesn’t fall on the individual completely, like many fossil fuel companies would like you to think. They spend a tremendous amount of money trying to make us think that carpooling and recycling will save us, when it wont. Anyway, I agree with you.

January 15, 2022 at 10:29 pm
Because environmentalists are realists. They know reducing meat consumption simply won’t happen without a fundamental shift in behaviour. It’s not economically viable in the short term to do that, and humans are incredibly short sighted about short term cost and long term gain, hence the presenting the next best thing that can literally start working overnight

Very inspirational ideas and presentation. With regard to cutting down emissions in cattle production, do you think using airtight indoor farms were the excreted air could be directed to algae production for example (where methane can be a source of food) could be a viable solution? Not really sure how would be the cost of such a farm and if a farmer economically would benefit from it but because meat consumption as it goes will not be able to reduce emissions as we want, so then at least the meat we produce comes from a production system which handles the ch4 responsibly and of course also its cows (the cows do not need to be the whole day within an air tight barn as C02 and methane production follow specific patterns within day and night meaning parts of the day were cows emit most methane needs to be indoors).

This HAS to a beef industry sponsored “scientist”.
First, the problem with beef is not only the methane production but the near catastrophic depletion of the world’s aquifers for crops to feed the critters. Higher quality feed? It’s purpose grown already.
I would like to see one (1) legit peer reviewed study identifying quantifiable methane reductions from “new technology”. The only ones I known of are focused on growing quality protein in the lab.
The absolute fastest way to reduce methane emissions, aside from tightening some bolts?
Stop eating beef. Choose another meat source. Cattle kills. It’s that simple.

This video makes excellent points. Also shows how off-base politicians are in their climate change rhetoric. All we hear is “cut CO2 emissions”; while nobody mentions methane or … the solution that Mother Nature already has in place for recycling CO2. Yes, I am talking about forests, a topic that seems to be “taboo”. Throughout the entire history of Earth, every time there was a higher CO2 concentration in the atmosphere, luxuriant forests developed, bringing the environment back to balance. But nobody seems to acknowledge that and while CO2 emissions are growing, forests are also being cut at increasing rates. Why? Well … could it be because politicians want money and power more than we all need oxygen?

The speaker is a scientist so I can’t believe she is saying what she is saying. I suspect she is overly simplifying and twisting the facts to make the topic understandable. But what she ends up saying is simply NOT TRUE
Regarding “we need to reach net zero to stabilize our climate” – NOT TRUE. Since the arctic and permafrost are both melting at CURRENT atmospheric CO2 levels, achieving net zero will only MAINTAIN current (or some future higher) atmospheric CO2 level. This means the arctic and permafrost will continue to melt, and climate change will continue to worsen.
Regarding: “when we reduce methane, we can reduce a lot of warming right away…” – NOT TRUE. Consider that CO2 is being emitted at 33-35 BILLION tonnes per year while methane is about 570 MILLION tonnes. In the atmosphere CO2 has been rising about 2-3 Parts Per MILLION per year. Methane increased last year about 14 Parts Per BILLION or 0.014 Parts Per MILLION. (1/74’th of CO2 – notice the unit of measure for methane is PPB which is 1/1000 that of CO2’s PPM)
Methane has an atmospheric half life of about 10 years while CO2 has an atmospheric half life of about 120 years.There is no denying that methane is a much stronger greenhouse gas than CO2 (about 70 times greater over those first 10-12 years). But, considering the tiny amount of methane emitted compared to CO2 (about 1/60th of Co2), and the vastly shorter half life of methane compared to CO2 (about 1/12th), and the lower yearly atmospheric rise of methane compared to CO2 (1/74’th of Co2), a reduction of methane alone will have only a TINY reduction in climate heating.
Regarding “if we succeed in cutting methane… we can… hit the breaks on worsening extreme events.” NOT TRUE – those events will continue because they are driven by CURRENT greenhouse gas emissions which remain in the atmosphere for over a century. Thus simply slowing (rather than reversing) atmospheric greenhouse gas emissions will NOT change the fact those extreme weather events will continue to happen. (Similarly, just slowing the speed of a car pointed at a cliff, will not change the fact that the car will sooner or later go off the cliff.)
In summary, this is one of those pseudo-scientific talks meant to make people feel good. But it is of little actual informational value. Are TED talks becoming “feel-good” talks?

Yes our planet is going through a climate change. The planet is getting warmer. However, all the people on our planet is cause for a small percentage. Our Earth over its lifetime has gone through a lot worse than this and survived. If you do your homework you will find out that our planet’s magnetic poles are in the very early stages of a flip. The Earth is long overdue for this event. It will probably take 1000 to 10000 years to complete. During this period of time it has been estimated that 90 percent of the life on Earth will die. The Earth will survive and when the flip is complete our planet will will look like a teenage again. The big question is why would this happen. The answer is quite simple. Our Earth and everything on it is a digital copy of the real planet Earth. We are living in a computer simulation. Right now a few people on our planet have been visited by the alien human race on the real planet Earth.

Easiest solution: stop eating beef and dairy.

How about reducing our consumption of meat? This also has the massive advantage that trees can be planted on the land that is freed up when we stop feeding the soya and corn to animals. Trees will take huge amounts of carbon dioxide out of the atmosphere, giving a double benefit.

When she didn’t include any of that important and tangible information, I switched it off. You cannot have recovery without sacrifice.

This was a good talk. Whoever, everyone wants to solve the “symptoms”, but no one wants to address the “cause”: overpopulation.

I think that speeches like this are more dangerous than the speeches made by climate deniers. We can’t TECH OUR WAY OUT of the climate crisis people! That’s what led us here, not just the technology itself, but the lazy, profit driven motivation behind it. We need to start valuing ECOlogy over ECOnomy and start changing our habits, starting today. That’s more like yesterday, for us the in the “advanced” countries.

We couldn’t “tech our way out” of many situations where that’s just what we did. What led us here was not technology, it was wealth accumulation, overpopulation, waste, commercial production and industrial lobbying including fossil fuels which are at this point fully replaceable. Instead of kicking strops in the comments that “we” need to do something, let the world “leaders” and the many assorted corporate monsters take heed instead of copping out and blaming us for the pollution they make.

We weren’t even able to study worldwide weather until 1888. That’s 124 years. The earth has been around since what, 6 to 13 billion years. The arrogance of little men and women knows no bounds.

Well gee I don’t know uh the media is saying the southeast is gonna have a once in a decade ice storm. That must be because the earth is warming up right? Yeah right. This is all just part of the woketard movement. These scientists get here he government grants as long as they keep the global warming alarm going. Kind of like Howard Stern. He use to be someone the average man could identify with buy now that the deep state has given him millions of dollars he’s a vaccine promoter. Now he says if you aren’t vaccinated you should be in jail or dead. Some of these days the deep state, woketard and paid liars will have to answer for their sins and I’ll be there to see that. 😂

very interesting levers which are presented on this TED in a methodological way. but I’m afraid of the permaftost melt that will be a most important effect and the question is what we can do ?

This reeks of capitalistic intent and the eco-modernism ideology.
Technology isn’t going to save us despite our bad habits. Gov’t needs to step up with legislation, people in wealthy nations need to reduce their energy consumption. And I’m fully aware of the irony(or hypocrisy, if you prefer) of being plugged in to write this comment.

How could she identify cattle as the single largest cause of methane emissions, then completely fail to recommend reducing or eliminating meat from our diets?
At the precipice of climate catastrophe, we know the meat industry is one of the largest contributors to greenhouse gas emissions, deforestation, and loss of biodiversity. And yet so many still find it unpalatable to propose the single simplest solution: stop eating meat. Insanity writ large.

I remember in the 80’s and everybody being afraid of the Ozone layer, they told us we’d all die from that then as I got older, it became Global Warming, everyday you heard about the greenhouse affect and people needed to walk instead of driving cars or we’d all die from that now in the past 10 years it’s all about climate change – the narrative has shifted three times in my life…
The sun is entering a cooling cycle and we can not do anything about it.
I think the Earth is better at healing itself than any money you can throw at it.

The root cause of “climate change” is too many humans.
Pavel Kushnirchuk

Climate change is not related to human activity. It’s a cyclic process. Ask geologists. Many so-called “scientists” try to persuade us that human activity is the cause of climate change, but it is simply the way to start a new, VERY BIG business. These “scientists” have been “fighting” with CO2 for about 40 years, spending billions of dollars every year, but we don’t see any results. And now they say that they should spend again billion dollars for “fighting” with methane. Guess who pays for all this s…t ? We pay for that. Buy the way. Do you know that there are CO2 quotes that can be sold and bought, like currency?
If you want to know the truth about climate change you can watch the conference “Global Crisis. Time for Truth”
