Climate Change - Veritasium

bcglorf says...

Not sure of the relevance of how long I've "believed" there is climate change happening? I'd argue as just another laymen nobody should be putting any stock in my opinion based on my credentials in any way. Compare what I say is in the actual IPCC reports, to what is actually and honestly in them for yourself instead. To the strict and bare question, I don't really know how long, more than a decade though to be sure.

Wealth redistribution is basically any form of taxation. Moving money from entity X to entity Y for justification Z.

Climate Change - Veritasium

bcglorf says...

Amateur videos on you tube by guys who clearly haven't read or understood the scientific journal articles on the subject are part of the problem and confusion.

The point of recycling is to reduce energy use and transportation in manufacturing materials... So yeah, it's part of the solution and not to be thrown away.

Yes, the plant is warming, and scientists are agreed on that.
Yes, humans are adding significant CO2 to the atmosphere which contributes to warming.
What is the severity of the warming over the next 100 years, and what difference do our actions today make, and what cost do those actions have?

See the first 2 points are agreed and help understand some of the problem. The trick though is that the severity is still known with less certainty, read the details in the latest IPCC AR5 report if you doubt me. The error bars within the scenarios(different carbon emissions we reduce or increase to) span multiple degrees of temperature. The error bars are only as accurate as the current days models, which still are uncertain of the sign to attribute to water vapor as a feedback. The water vapor that contributes more to the greenhouse effect than all other GHG's combined. How great is the economic cost of reducing our emissions to meet each scenario? That's no in the IPCC report. What is the alternative cost of adapting to the temperature ranges if we just continue emitting? Again not there.

The trouble is there DOES still exist uncertainty on a great many aspects of the problem. Random amateurs proclaiming otherwise on youtube doesn't change that. Until we've got a good grasp on the cost/benefit differences between reducing emissions and adapting to changes, we can't make any claims on action X is obvious because of climate change.

Now, I'm not advocating we do nothing. Electric cars are a huge opportunity, and the technology is finally hitting the threshold of being cheaper than gas. Adopting that technology makes economic sense. A fringe benefit is that it reduces emissions from transportation drastically too.

There are solutions other than redistribution of wealth through naive/blind carbon taxes.

Why People Doubt Climate Science, And Why Facts Don't Matter

bcglorf says...

People doubt climate change because the noise of the people pushing agendas has drowned out the actual science. Even the major media, both 'defending' and 'attacking' climate change all get things entirely wrong and misrepresent the actual science. Lets be honest most people, particularly many of the people claiming to be well informed, really haven't looked at the actual science available and assessed it honestly.

99% of the world right now fits into two camps, the 'believers' defending the coming apocalypse that we've created and must adapt to yesterday, and the deniers who disagree.

The actual scientists observing that there is a warming trend that we are contributing to aren't listened to be EITHER side. When the IPCC posts projections for 2100, even the IPCC most optimistic view riles up the deniers and even the IPCC most gloomy view is dismissed by the 'believers'.

Don't hold out any hope that facts, reason and logic are gonna shift humanity anytime soon. Historically speaking it's pretty much not gonna happen,

The Newsroom's Take On Global Warming-Fact Checked

notarobot says...

"All of these things are predicted by the IPCC—I mean, not the permanent darkness thing, I don't think that's meant to be scientific. But yes, as we reported in May this year, Europe faces freshwater shortages; Asia can expect more severe flooding from extreme storms; North America will see increased heat waves and wildfires, which can cause death and damage to ecosystems and property. Especially in poor countries, diminished crop yields will likely lead to increased malnutrition, which already affects nearly 900 million people worldwide.

So, in all, well done Newsroom. Informative, accurate, if a little heavy-handed on the doom and gloom." /Mother Jones fact check

@Trancecoach
dude,its a TV show..relax.

i agree that a political argument dressed as scientific debate is a bait and switch that most people miss and buy into the bullshit.take the politics and monied interest out?

well,not much arguing going on.

now the discussions in regards to solutions are in the political realm and that my friend,scares the bejesus out of me.its like asking a crack whore to watch your kids.

how sad and shameful that the most progressive and creative solutions are coming from third world nations.these people crap outside for fucks sake!

but here in the states? too busy texting and facebooking and searching for that next new shiny,because our self worth is wrapped in what we own,what we do for a job,what we drive.we demand respect from everyone yet give none,convinced of our own superiority based on the most thinnest of veneers and baseless of subjective criteria.

we are the assholes of the world.

lets be real for a second.
this video is based on a show.entertainment.
and it plays it way over the top,but its entertaining.
its just a tv show.

i have seen some climate models that predict as early as 2050 shit is going to hit the fan,while others play it around 2100 (that was the IPCC one).all predicting some really nasty global stuff.

we aint gonna make it to 2100.
hell,i would be surprised if we made it to 2050.
because there is something far worse that will affect our societies than climate and thats peak oil.

how come nobody is talking about that?
far worse implications in regards to:food,clothes,jobs,economies did i mention FOOD?
oh,and war..lots and LOTS of war.killings,maimings and murders..oh my.
no arguing the science on that one,thats been in since the late 70's.

where is the debate on a subject that has real and immediate ramifications?

such a failed species.......

The Newsroom's Take On Global Warming-Fact Checked

Trancecoach says...

Like most of Sorkin's bloviating, this empty rhetoric is undermined by the incongruency of the climate change alarmists' own ballooning carbon footprints while attempting to use the government to impose force upon others' behavior. Until global warming alarmists themselves walk their talk (i.e., drive hybrids -- if they drive at all -- cease flying in airplanes, eat strictly vegetarian diets, have few if any children, and withdraw their consent from the worst polluter on the planet: the state), then no amount of freaking out, ranting, incentives, or attempts at policy will serve to avert the "impending catastrophe."

In China and India (where pollution is no doubt a significant problem), there are hundreds of millions of people who have far bigger concerns and more pressing problems than some remote notion of a "warming planet" or some looming "catastrophic collapse of civilization." (In fact, the same can be said for the majority of the population of the planet.)

And this is to say nothing of how ALL of the models used to support "evidence" for the case of a warming planet have ALL (not some, but ALL) been consistently undermined by serious skeptical science (PDF) while the claims of the political entity of the IPCC remain inconsistent with the data.

Since when do politicians get to decide the veracity of scientific fact?

EDIT: ALL of the climate-change alarmists' predictions, dating back to the 1980s, have all failed to come true. When this trend continues for the next few decades, there will be no shortage of "Told You So" moments that will undoubtedly be explained away by some unknown variable -- like the heat that is "hiding" in the ocean -- that, once "corrected for," will serve to further prop up this political ruse.

Doubt - How Deniers Win

bcglorf says...

You can call it 'personal belief', I call it educated guess work, because I've paid attention and most models were on the low side of reality because they don't include all factors

Try as I might, I just can't ignore this. Here's what the actual scientists at the IPCC themselves have to say in their Fifth Assessment Report on assessing climate models:

an analysis of the full suite of CMIP5 historical simulations (augmented for the period 2006–2012 by RCP4.5 simulations, Section 9.3.2) reveals that 111 out of 114 realizations show a GMST trend over 1998–2012 that is higher than the entire HadCRUT4 trend ensemble
For reference the CMIP5 is the model data, and the HadCRUT is the instrumental real world observation. 111 out of 115 models significantly overestimate the last decade. AKA, the science says most models were on the high side.

Now, that is just the last 10 years, which is maybe evidence you can declare about expectations going forward. But lets be cautious before jumping to conclusions as the IPCC continues on later with this:

Over the 62-year period 1951–2012, observed and CMIP5 ensemble-mean trends agree to within 0.02ºC per decade (Box 9.2 Figure 1c; CMIP5 ensemble-mean trend 0.13°C per decade). There is hence very high confidence that the CMIP5 models show long-term GMST trends consistent with observations, despite the disagreement over the most recent 15-year period.

So the full scientific assessment of models is that they uniformly overestimated the last 15 years. However, over the longer term, they have very high confidence models trend accurately to observation.

As I said, if your personal belief is that models have consistently underestimated actual warming that's up to you. Just don't go spreading doubt about the actual science while sneering at others for doing exactly the same thing solely because they deny the science to follow a different world view than your own.

This is getting old.
If production were simple, ie not requiring extra water and fertilizer, everyone who's hungry would farm, and there would be 'bush taca' (wild food) to gather and eat. You can't make a living stealing from subsistence farmers, you go hungry between farms that way.
I point out that historically you are wrong. I cite specific examples illustrating that you are wrong. Still you come back insisting that somehow men with guns can't starve people out who want to farm. That somehow the mass starvations under Stalin, Mao, and North Korea weren't even related to the mass theft at gunpoint of farm crops and land from farmers. You insist that it's not what is today stopping farmland from productivity in places like the DRC, Liberia, Sudan, Somalia, Yemen, and many more. I give up.

the tech to replace oil and coal and gas exist today
But also
we can't get to the moon with NASA today, or get on a concord
I give up.

78% less glacier doesn't mean ...
I think those numbers are small, and it's likely that there will be less than 22% of glaciers left in 100 years

I cited the actual science from the IPCC with their own projections. You take the very, very worst of the multiple scenarios the IPCC run. Not content with that, you take the most extreme range of error within that extreme scenario. Not content with that, you then inject your PERSONAL BELIEF that even that position of science is likely to optimistic.

I give up. If you refuse to listen to fact and reason that's up to you. Just don't pretend your any better than the other side ignoring the actual science just from a different end of the spectrum.

@newtboy
I think the people of Kiribati would disagree that it's not time to panic!
If you'd read my post I didn't claim the people of Kiribati weren't in a position to panic. I actually went further in agreeing with you, to the point that they should have been panicked a hundred years ago in 1914 already. The distinction being that what ever the climate does wasn't going to save them. 200 hundred years of cooling and sea level decline from 1914 would still have them on an island a few feet on average above sea level and still a disaster waiting to happen.

California alone, which produces over 1/4 of America's food,
Here we do have a difference of fact. I don't know what measure you've imagined up, but the cattle in texas alone are more than double the food produced in California. The corn and other crops in any number of prairie states to the same. You can't just invent numbers. Yields across crops have been increasing steadily year on year in North America for decades.

The violence is often CAUSED by the lack of food, making the 'men with guns' have a reason to steal and control food sources. If food were plentiful, it would be impossible for them to do so.
I'm sorry, read more history, you are just wrong on this. 10 guys with guns against 10 farmers with food and the farmers lose every time. The guys with guns eat for the year. The farmers maybe even are able to beg or slave for scraps that year. The next year maybe only 5 farmers bother to grow anything, and next harvest there are 15 guys with guns. Look at the Russian revolution and that's exactly the road that led to Stalin's mass starvations and lack of food. It's actually why I am a Canadian as my grandfather's family left their farm in Russia with the clothes on his back after the his neighbours farm was razed to the ground enough times.

The thugs SELL that food, so it doesn't just disappear
Food doesn't create itself as noted above. The cycle is less and less food as the thugs destroy all incentive to bother trying to grow something.

adopting new tech, even quick adoption, absolutely CAN be an economic boon
I agree. I hadn't realized that adoption of new tech was that simple. I was under the impression one also had to take the time to, you know, invent it. The existing technology for replacing oil and coal cost effectively doesn't exist yet. Electric cars and nuclear power are the closest thing. The market will adopt electric cars without us doing a thing. Switching from coal to nuclear though, even if universally agreed and adopted yesterday, would still take decades for a conversion. Those decades are enough that even if we got to zero emissions by then(~2050), the sea level and temperature at 2100 aren't going to look much if any different(by IPCC best estimates).
So I repeat, if you want meaningful emission reductions, you have no other option but restricting consumption across the globe. That hasn't been accomplished in the past without setting of wars, so I keep my vote as cure is worse than disease.

The 78% glacial mass loss was worst case if CO2 emissions are still accelerating in 2100. The mountains with the glaciers will still be bulking each winter and running off each summer, just to a 78% smaller size in the depth of summer. As in, absolutely not 78% less run off. And they are not 'my' numbers as you wish to refer, but the IPCC's numbers. Your effort to somehow leave question to their veracity is the very campaign of 'doubt' in the science the video is talking about.

I'm guess from you're tone your American, or at least only figure Americans are going to be reading? You note that 'we' can't get to the moon, while Chinese rovers navigate it's surface. You note with alarm what coastal Florida will face from sea level rise, and not an entire nation like Kiribati. When we look at a global problem we can't ignore technology just because it's Chinese, or focus so hard on Florida's coast we ignore an entire nation in peril.

Sea levels aren't going to be fine in 2099 and then rise a foot on the eve of 2100. They will continue to rise about 3mm annually, as they have already for the last 100 years.(on a more granular level slightly less than 3mm nearer 1900 and slightly more nearer 2100 but the point stands). Coastal land owners aren't merely going to see this coming. They've watched it happening for nearly 100 years already and managed to cope thus far. Cope is of course a bad word for building housing near the coast and at less than a foot above sea level. It's like how occupants at the base of active volcanoes 'cope' with the occasional eruption. All that is to say, the problem for homes built in such locations has always been a matter of when not if disaster will strike. The entire island nation of Kiribati is barely above sea level. It is one tsunami away from annihilation. Climate change though is, let me be brutally honest, a small part of the problem. A tsunami in 1914 would've annihilated Kiribati, as a tsunami today in 2014 would, as a tsunami in 2114 would. And we are talking annihilate in a way the 2004 tsunami never touched. I mean an island that's all uninhabited, cleared to the ground and brand new, albeit a bit smaller for the wear. That scenario is going to happen sooner or later, even if the planet were cooling for the next 100 years so let's be cautious about preaching it's salvation through prevention of climate change.

Your points on food production are, sorry, wrong. You are correct enough that local food growth is a big part of the problem. You are dead wrong that most, or even any appreciable amount is to blame on climate change now or in the future. All the African nations starving for want of local food production lack it for the same reason, violence and instability. From this point forward referenced as 'men with guns'. The people in Africa have, or at least had, the means to grow their own food. Despite your insistence that men with guns couldn't stop them from eating then, they still did and continue to. A farmer has to control his land for a whole year to plant, raise and harvest his crop or his livestock. Trouble is men with guns come by at harvest time and take everything. In places like the DRC or Somalia they rape the farmer's wife and daughters too. This has been going on for decades and decades, and it obviously doesn't take many years for the farmer to decide it's time to move their family, if they are lucky enough to still be alive. That is the population make up of all the refugee camps of starving people wanting for food. It's not a climate change problem, it's a people are horrible to each other problem. A different climate, better or worse growing conditions, is a tiny and hardly worth noting dent in the real problem.
CO@ emission restrictions do not equate to global economic downturn, they could just as easily mean global economic upturn as new tech is adopted and implemented.
I stated meaningful CO2 emission changes. That means changes that will sway us to less than 1 foot of sea level change by 2100 and corresponding temperatures. Those are massive and rapid reductions, and I'm sorry but that can not be an economic boon too. I'm completely confident that electric cars and alternative or fusion power will have almost entirely supplanted fossil fuel usage before 2100, and because they are good business. Pushing today though for massive emission reductions can only be accomplish be reducing global consumption. People don't like that, and they jump all over any excuse to go to war if it means lifting those reductions. That's just the terrible nature of our species.

As for glaciers, I did read the article. You'll notice it observed that increasing the spatial resolution of models changed the picture entirely? The IPCC noted this and updated their findings accordingly as well(page 242). The best guess by 2100 is better than 50% of the glaciers through the entire range remaining. The uncertainty range even includes a potential, though less likely GAIN of mass:
. Results for the Himalaya range between 2% gain and 29% loss to 2035; to 2100, the range of losses is 15 to 78% under RCP4.5. The modelmean loss to 2100 is 45% under RCP4.5 and 68% under RCP8.5 (medium confidence). It is virtually certain that these projections are more reliable than in earlier erroneous assessment (Cruz et al., 2007) of complete disappearance by 2035.

If you still want to insist Nepal will be without glaciers in 2100 please provide a source of your own or stop insisting on contradicting the science to make things scarier.

Then slow down with theories of our impending demise, the IPCC doesn't support it. You want to talk about not denying the science, then you don't get to preach gloom and doom. Don't claim a large percentage of farmland is going to be lost to sea level rise by 2100. Don't claim coastlines are going to be pushed back 10 miles by a worst case 1 foot rise of sea level by 2100.

We are talking about advancements solving problems like a maximum sea level rise of a foot in the next 100 years, with best guesses being lower than that. I think it's modest to suggest our children's children will have figured out how to raise the dikes around places like New Orleans by a foot in the next 100 years.
The concord and moon trips are no longer happening because they are expensive. We can do them if we needed to, and more easily than the first time around. Finding out people aren't willing to pay the premium to shave an hour off their flight doesn't mean the technology no longer exists. Just because America no longer needs to prove they can lift massive quantities of nuclear warheads into orbit doesn't mean we couldn't still go to the moon again if it was needed. There's just no reason to do it, the tech exists still none the less.
Yes, there are social problems that confound the use of new technology. You fail to notice that is also the problem with feeding everybody. Food production isn't the problem, but rather the men with guns that control distribution. Stalin's mass starvation of millions was a social problem, not climate change or technology. Mao's was the same. North Koreas the same. All over Africa is the same. We have more than enough food, and plenty of charities work hard to send food over to places like Africa. Once the food gets there though the men with guns take most of it and people still starve. The reason Africa has so many crop failures is the violent displacement of the farmers. Exactly the same problem that saw millions starve in Russia, China and North Korea.
You are right that a changing climate could compound Africa's ag industry a bit, but it's a small hit compared to the violent displacement problem. Also, don't neglect to consider to impact of meaningful CO2 emission restrictions around the globe. A large scale global economic downturn probably means a lot more war, bloodshed, and starvation. If you do not reduce emissions enough to trigger that downturn and instead just 'marginally', you get stuck with both because Africa is still going to see virtually the same climate changes through the next hundred years.

And if you are worried about losing the glaciers in the Himalayas by 2100 there is very good reason to believe that's gonna be alright:

Slow down with the theories that our 'advancements' will solve all problems, not create more, because all the things you listed have been fairly disastrous in the long run, many being large parts of the issue at hand, climate change, and things like putting a man on the moon or traveling the globe in hours have gone backwards, meaning it was simpler to do either 35-45 years ago than it is today (we can't get to the moon with NASA today, or get on a concord). Assuming new tech will come along and solve the problems we can't solve today is wishful thinking, assuming they'll come with no strings attached means you aren't paying attention, all new tech is a double edged sword in one way or another.
IF humans could harness their tech, capital, and energy altruistically, yes, we could solve world hunger, disease, displacement, etc. Humans have never in history done that though.
We already can't feed a large percentage of the planet. If a large percentage of farmable land is lost to sea level rise (won't take much) and also a large population displaced by the same (a HUGE percentage of people live within 10 miles of a coast or estuary), we're screwed. It will mean less food, less land to grow food, more displaced people, less fresh water, fewer fisheries, etc. We can't solve a single one of these problems today. What evidence do you have we could solve it tomorrow, when conditions will be exponentially less favorable?
For instance, something like 1/3 of the population survives on glacial water. It's disappearing faster than predicted. There's simply no technology to solve that problem, even desalination doesn't work to get water into Nepal. People seem to like water and keeping their insides moist, how would you suggest we placate them?

Hottest Year Ever (Global Warming Hiatus) - SciShow

Trancecoach says...

As I'm sure you know, empirical data needs a theory in order to interpret it and make sense of it. So far, climate change models (i.e., the theories upon which their data is interpreted) have failed, by the proponents' own admissions. And they have not been able to disprove counter theories either. So the debate goes on within the scientific community. Meanwhile, activists, politicians, and "journalists" don't know how to come up with these theories, so they rely on what they know how to come up with: ideologies, rhetoric (which they, themselves, may not believe), hermeneutics and other poor substitutes for rationalist theory through which to interpret the data.

So far, all of the "arguments" I've heard in support of climate change draws upon the IPCC as the source of its "evidence." What they don't realize is that the IPCC is a political organization, not a scientific one.

Since when do politicians decide on the "truth" about scientific fact?

Slow down on the we need to panic soon or we are even too late for panic. The IPCC estimates through to the year 2100 do not show unmanageable changes. We can adapt to the temperature and sea level changes expected. More over, that is based on today's technology. We are talking nearly a hundred years in the future. 100 years ago cars, planes, refrigerators, spaces ships and nuclear weapons were all yet to be discovered or known to the public. Problems like putting a man on the moon or travelling the globe in hours seemed insurmountable then. They are done and a matter of course to us today.

Apologies, but with all due respect panic hardly seems called for over a temperature and sea level increase we can handle currently pending on us in a hundred years. Something tells me it'll give the people then with hundred years of advances more if a laugh than a burden.
