They can't even get the weather right in my country half the time, why would i think they can predict with any accuracy what will happen decades from now?

>I can't predict the precise moment I'm going to take a shit tommorow therefore it's wrong to predict that I will take a shit tommorow
(You)

I don't think it isn't true, I just don't care that much.
Imo overpopulation is a much bigger issue.

I don't usually shit every day and I'm not even joking when i say i just went and took a shit in between posting that and seeing your reply so it would be probably be wrong if i predicted a shit tomorrow.

weather and climate are completely different things brainlet

>not knowing this
>posting on Veeky Forums

This is not to be a stalker, It's to see how psychological worries are. Where are you from?

because politics

Because we're being told to pay no attention to our lying eyes, to the numbers, the data. Instead listen to the scientists who are receiving huge grants

It was "global cooling" 25 years ago due to some political reasons. Same amount of charts, scientists and data showed up to support global cooling. Now it's "global warming" due to some other political bullshit.

I'm just not playing.

lmfao

another brainlet detected

>gottdamm global warmin', we's been havin tha coldest winters yet - how is that warmin mr college man?
>scientists dont know what theyre talking about

climate change operates at both extremes fucking brainlet cunts
- severe storms
- lower lows
- higher highs

I can't hear you over the noise of you smashing your keyboard with rage :^)

This board is being very severely raided.

>global warming meme
you dumb paranoid schizo freak

And its fun
I said nothing about beliefs in it.

>mr college man
>believes in global warming meme
AHAHAHAHAHAHA how pathetic are you ? Do you think /x/tards like you even have any degrees?

Take this schizo garbage thread where it belongs

I'm from the Netherlands

Nope go back to 8gag you nigger.

climate change is real.

global warming doomsday has about as much credibility as flat earthers do.

My issue is the time frames and reference points.

We're still in a Icehouse environment and the world has spent 80% of its time in a Hothouse environment.

We have hard evidence going back a few hundred thousand years on a cycle that works in millions of years. Carbon and methane heat things up in a tiny lab so the IPPC go off that in the main as they can't gather enough data on a planetary level set of variables.to a) accurately predict or b) politically stop Co2 levels.

All in all, some developing nation, under huge political demographic pressure will resort to enviro-engineering within the next century. Bangladesh or Pakistan would be favourites.

At the end of the day they are still trying to predict what the weather will be like in x number of years; calling it climate or whatever doesn't change this simple fact.

Also Veeky Forums has and always will be a meme board.

Because all their earlier predictions failed.
Numerous studies have been proved to inflate the numbers in order to be published.
Heavily politicized = heavily biased .
Big bucks flowing on both side.

>We're still in a Icehouse environment and the world has spent 80% of its time in a Hothouse environment.
How is that relevant to whether or not AGW will harm us?

>We have hard evidence going back a few hundred thousand years on a cycle that works in millions of years.
So you are concerned about what will happen millions of years from now and not about what will happen in the next hundreds? This seems like some hardcore mental gymnastics to deny AGW.

>Carbon and methane heat things up in a tiny lab so the IPPC go off that in the main
Except we can directly measure the infrared spectra of greenhouse gases in the atmosphere. This is what the radiative forcing methods are based on, not experiments in a lab. Where do you people get this nonsense? And then you write as if you know anything about climatology. You're only fooling yourself. It's pathetic.

But it's not based solely on any one model user. It's based on observational evidence and simple physics. The idea of climate change has been discussed since the late 19th century by the scientific community and was largely resolved by the mid-20th century. It usually takes a long time for the public to come grips with what the scientific community readily understands to be true. But it could all just be a conspiracy right user?
>Numerous studies have been proved to inflate the numbers in order to be published.
Show me a reputable source that says climate change isn't real. In addition, there would be no reason for climate scientists to "make up" anything. That's not how funding works. Once you've resolved an issue, you lose funding. This means if climate scientists were in it for the money, they would say "climate change may or may not be real so we need more funding." Instead, they're saying "why are we still debating what has been accepted by the scientific community for 50 years? This is a tremendous waste of time, money, and energy."

If you want talk about money, let's talk about the fossil fuel industry. Those guys have a lot of money riding on us forgetting about climate change. It's way more than pennies most researchers get (you do not get into science to make money).

Climategate

31,487 American scientists have signed this petition,

>there is no convincing scientific evidence that human release of carbon dioxide will, in the forseeable future, cause catastrophic heating of the Earth's atmosphere

Stop pretending all the scientists agree with you and only retards don't.
Those who disagree are just not shown in your medias.

>Why are you doubting global warming?
I don't doubt it. I doubt that it's important that the US spend billions of dollars to manage it in other countries. Other countries that find the need so pressing they're willing to spend exactly zero on it themselves.

Scam politics on real science.

31000 seems like a big number, until you realise there's a 97% consensus on AGW

>meme statistics
If you don't know why this is an obviously memed number then you don't understand climate change science.

How many of them have a degree in an actually relevant field?

Please, tell me more

Never mind, found it.
> I) Atmospheric Science (112)
>II) Climatology (39)
I guess "151 people whose opinions carry any credit have signed this petition" didn't sound as good.

Must of them are not scientists, just people with a STEM bachelor's degree. And essentially none of the few scientists in the list have any expertise relevant to climatology.

Your mother didn't have a degree in whoredom but she still managed to take enough dick to produce you.

check potholler54's channel who is an science journalist and has a series on global warming which is the most scientifically accurate


for the short version, AGW is happening and it is due to increased CO2 in the atmospher(of hwich we are only partly to blame). But the right wing is a bunch of morons who think it doesnt happpen and the left wing are a bunch of morons who think i'll be the apocalipse and distort the science.

Global warming has incresed the sea level by some centimeters and in 200 years at the current rate, the sea level will increase by up to 1 meter(which is still something we can manage). It is predicted that global warming will produce damage between 5%-20% of the global GDP if we don't do anything about it.

global warming also made me fail my calc2 exam

damn global warming :(

so you rather trust 1 out of 10 scientist that are paid by oil companies because 9 out of 10 scientist say global warming is real and receiving grants from other sources?

topkek

Someone on TV said global warming was real.
Then someone onTV said it was fake.
I guess weather its real or not is just a matter of opinion.

AGW SHILLS BTFO

Financial motivation doesn't make sense; oil companies have a lot more money, and would be happier to give more to scientists showing AGW a shit

wow you're dumb. try reading before you post.

>How is that relevant to whether or not AGW will harm us?
How is it relevant that the normal? No, erm predominant state of the Earth is a hothouse environment? That without humanity, the Earth is highly likely to revert back to a hothouse environment. That's the relevance. It isn't about how it will harm us or not, it's about the probability of a hothouse environment occurring with AGW or without and there is no way of knowing if it would have occurred sooner or later without humanity. We simply don't know and to say you do is fruitcake territory.

>So you are concerned about what will happen millions of years from now and not about what will happen in the next hundreds?
No, you've missed the point. We're trying to gauge something that works in cycles, variable and data masses we can't as yet understand. Nevermind predict.

>This seems like some hardcore mental gymnastics to deny AGW.
ad hominem. It's not about denying AGW, we've (humanity) has had a affect on the environment since we began cutting down trees and domesticating wild life.

>Except we can directly measure the infrared spectra of greenhouse gases in the atmosphere. This is what the radiative forcing methods are based on, not experiments in a lab. Where do you people get this nonsense?
>ad hominem. So laboratory work is not involved or used by the IPPC to further it's understandings of the data provided? Brilliant, so it's all based off greenhouses gases in the atmosphere. Thanks, didn't know that. Oh, erm how do they know what 'radiative forcing methods' results imply? Big question. Hint: from a Lab.

>And then you write as if you know anything about climatology. You're only fooling yourself. It's pathetic.
See, i not fooling myself, the IPPC is well aware that AGW is a thing and that whatever a bunch of cunts having isn't going to stop humans like Pajeet and the millions like him burning coal to heat his tea or cows farting.

>I don't doubt it. I doubt that it's important that the US spend billions of dollars to manage it in other countries.

But we're paying for the costs of global warming right now.

miamiherald.com/news/local/community/miami-dade/miami-beach/article102127612.html

No it wasn't, global cooling due to upper atmosphere aerosols was never a mainstream hypothesis and the idea that is was is pure revisionism.

because we only have data from 150 years back

>>We have hard evidence going back a few hundred thousand years on a cycle that works in millions of years.
>So you are concerned about what will happen millions of years from now and not about what will happen in the next hundreds? This seems like some hardcore mental gymnastics to deny AGW.
>Its happening soon, therefore its true!
Thems some nice circular reasoning


>>Carbon and methane heat things up in a tiny lab so the IPPC go off that in the main
>Except we can directly measure the infrared spectra of greenhouse gases in the atmosphere.
Meme science. CO2 induced temp increase is logarithmic and almost all energy that CO2 can absorb has already occurred.

>It was "global cooling" 25 years ago due to some political reasons. Same amount of charts, scientists and data showed up to support global cooling. Now it's "global warming" due to some other political bullshit.
Almost no scientists said this. Shit media /reported/ on it, but media has proven time and time again that it can't be trusted to report honestly on science.

oh here we go with this again

why don't you try googling global cooling instead of remembering a rush limbaugh talking point

as an user stated above, it was not considered mainstream and that specific talking point has been debunked countless times

journals.ametsoc.org/doi/pdf/10.1175/2008BAMS2370.1

"Global cooling was a conjecture during the 1970s of imminent cooling of the Earth's surface and atmosphere culminating in a period of extensive glaciation. This hypothesis had little support in the scientific community, but gained temporary popular attention due to a combination of a slight downward trend of temperatures from the 1940s to the early 1970s and press reports that did not accurately reflect the full scope of the scientific climate literature, which showed a larger and faster-growing body of literature projecting future warming due to greenhouse gas emissions."

Sorry you got BTFO

>basing global temperature predictions off of a time period of only 136 years

try harder

Meanwhile Warmists; AKA watermelons; Green on the outside, red on the inside. Are certain of CO2 induced death by 30 years of temperatures.
See: Sorry you got BTFO. Changing the subject won't help you much.

try looking farther back than 1880

Speculative graphs mean nothing.
And the instrumental 'spike' in temps from about 1950 to now?
Put that spike through a 100 year average smoother and it disappears.

>How is it relevant that the normal? No, erm predominant state of the Earth is a hothouse environment?
Again, so what? It's not normal to humans.

>That without humanity, the Earth is highly likely to revert back to a hothouse environment.
In millions of years, yes. Again so what? I am concerned with the harmful effects of rapid warning on humans. I see no reason to be concerned with what particular climate the earth usually is or will be in millions of years.

>It isn't about how it will harm us or not, it's about the probability of a hothouse environment occurring with AGW or without and there is no way of knowing if it would have occurred sooner or later without humanity.
This moronic attempt to distract from AGW by pretending to care about events millions of years away is pathetic.

>No, you've missed the point. We're trying to gauge something that works in cycles, variable and data masses we can't as yet understand. Nevermind predict.
The cycle you are trying to distract people with is on a timescale so large that it is irrelevant to AGW. That's what the thread is about. You are trying to the waters of the debate with read herrings and its failing.

Thanks, didn't know that. Oh, erm how do they know what 'radiative forcing methods' results imply? Big question. Hint: from a Lab.
This is tedious sophistry and dishonest arguing. You claimed that the IPCC based its conclusions off how greenhouse gases behave in a lab (as if this is somehow derogatory). I then corrected you by telling you that the effects of GHGs are measured directly. Now you are arguing as if I said lab work is not used at all. So are you unable to understand the argument or are you deliberately misrepresenting it?

Someone who is secure in their position does not need to lie and misrepresent arguments in order to argue for it. Maybe you should reconsider your position.

>>>So you are concerned about what will happen millions of years from now and not about what will happen in the next hundreds? This seems like some hardcore mental gymnastics to deny AGW.

First you completely avoided the question and then you made up an argument I never made. Scumbag rhetorical tactics.

>Meme science. CO2 induced temp increase is logarithmic and almost all energy that CO2 can absorb has already occurred.
Ah so you admit CO2 is a GHG and causes warming. Now I suggest you go research how much warming will caused by a doubling of CO2. Then research the effects of such warming. Then we'll be done.

Alarmist Studies Debunked:

Libardoni and Forest (2013)
This model–observation comparison Bayesian study (actually a corrigendum to a study originally published in 2011) uses an informative ‘expert’ prior distribution for ECS and an inappropriate uniform prior distribution for ocean heat uptake efficiency (the square root of ocean effective diffusivity, Kv). Use of such prior distributions will have biased, most probably upwards, the study’s ECS estimate. Using one surface temperature dataset, Libardoni and Forest find ECS to be lower,Kv
to be completely unconstrained, and aerosol forcing to be more negative, than the other two datasets are used. Yet with green-house gas forcing being offset to a greater extent by negative aerosol cooling and more heat being absorbed by the ocean, energy conservation implies that ECS would need to be significantly higher to match the twentieth-century rise in global temperatures, not lower. Since the Libardoni and Forest results thereby defy conservation of energy, they should be discounted. Although various errors pointed out in Lewis (2013) were addressed in this corrigendum, at least one was incorrectly dealt with, and the unsatisfactory way surface temperature data was used (see Lewis, 2013) was not altered, which may account for these problems.

Lin et al. (2010)
Although this study is dealt is really an energy budget study that uses numerical solutions of an energy balance model. The recent TOA imbalance is derived from an outdated AOGCM-derived Earth system heat uptake/TOA radiative imbalance estimate (Hansen et al. 2005) of 0.85 W/m, taken as applying over the final decade of the 1885–2005 period used. That heat uptake is twice as high as the best estimate per AR5 over the same decade. Moreover, no allowance is made for heat inflow into the ocean at the start of the 120-year period. The method and model used, in particular the treatment of heat transport to the deep ocean, is difficult to follow and appears non-standard. In view of the greatly excessive system heat uptake estimate used and the questionable methodology, it is difficult to regard the results of this study as constituting a realistic estimate of ECS. The IPCC authors evidently also had doubts about this study’s ECS estimate; its range is marked as being incomplete at both high and low ends.

Olson et al. (2012)
This model–observation comparison Bayesian study estimates ECS, ocean effective diffusivity and an aerosol-forcing scaling factor, using only global temperatures and a wide uniform prior on the aerosol-forcing scaling factor. That is an unsatisfactory method. Since greenhouse gas and aerosol forcing histories are extremely closely correlated (negatively), one can obtain a good match to historical global temperatures with a wide range of suitable combinations of ECS and aerosol forcing strength. That problem results in the study’s estimated PDF for ECS being almost unconstrained when using uniform prior distributions, which biases its ECS estimate upwards. The use of 0–700-m ocean, as well as surface, temperature changes provides only a very weak constraint on what ECS–aerosol-forcing combinations are feasible. Ozone forcing, which is significantly positive, was omitted: that can be expected to have increased the estimate of ECS substantially. Given all these problems, the Olson et al. instrumental ECS estimate cannot be regarded as realistic. Olson’s PDF and range for ECS shown under combination estimates is dominated by a non-uniform prior distribution for ECS that matches high AR4-era estimates for ECS, including from AOGCMs, as represented in Knutti and Hegerl (2008). Since the study’s combination ECS estimate is dominated by an initial distribution based on AR4-era ECS estimates, it should not have been treated in AR5 as if it were an independent observationally-based estimate. The Olson et al. combination estimate for ECS should therefore be disregarded.

Schwartz (2012)
>Schwartz flip-flopped into an alarmist, probably to retain his funding.
This study derived ECS from changes up to 2009 in observed global surface and 0–700-m ocean layer temperatures, and changes in forcing based on forcing histories used in historical model simulations. Two methods were used. One was zero-intercept regression of temperature change on forcing minus heating rate, fitted to post-1964 data. Whilst this approach appears reasonable in principle, subject to the forcing and OHC history estimates being realistic, the regressions are very noisy. No allowance was made for heat inflow into the ocean in the late nineteenth century (estimated in Gregory et al. 2002, to be non-negligible); that can be expected to have biased upwards its estimate of ECS slightly. For two of the six forcing datasets used, the regressions did not explain any of the variance in the temperature data – their R values were negative. ECS best estimates derived from the other four forcing datasets varied between 1.1 C and 2.6 C.The mean R value for their regressions approached a value of 0.5. The second method derived ECS by combining the results of similar regressions (but without deducting the heating rate from forcing) with an observationally-estimated heat uptake coefficient.

>continued
These regressions gave significantly higher R values. The second method gave similar results for the four forcing datasets for which the first method provided a valid estimate of ECS, with an overall range (allowing for regression uncertainty) of 1.07–3.0 C. A fifth forcing dataset, which gave a positive R only for the regression in which the heating rate was not deducted, gave an ECS estimate using this method of 4.9±1.2 C. That accounts for the ECS range for this study given in Box 12, Figure 1 of AR5 extending up to 6.1 C. The regression R for this forcing dataset was low (0.29) and the study concluded that the forcing dataset was inconsistent with an energy balance model for which the change in net emitted irradiance at the top of the atmosphere is proportional to the increase in surface temperature. The 3.0–6.1 C segment of the ECS range given for this study in AR5 relates entirely to this one forcing dataset and, in view of the problems with it, should be regarded as carrying significantly less than the one-fifth total probability that would otherwise naturally be assigned to a part of a range
that related only to one out of five datasets.

Tomassini et al. (2007)
The Tomassini et al. model–observation comparison study involved a complex subjective Bayesian method. For ECS, a set of priors varying between a uniform prior and a deliberately informative lognormal prior with a mean of 3 C, both restricted to the range 1–10 C, were used. A very inappropriate uniform prior was employed for ocean effective diffusivity (Kv) – the square of ocean heat uptake efficiency. The choices of prior for ECS and Kv will both have biased upwards the estimate of ECS. Although the method used encompasses inverse estimation of aerosol forcing via a scaling factor, only global mean observational temperature data is used, so the inverse estimate arrived at will be unreliable. The very high (negative) correlation between the time evolution of greenhouse gas and aerosol forcings on a global scale makes it impossible robustly to distinguish between different combinations of ECS and aerosol forcing values that each satisfy the energy budget constraint. The posterior distribution for Kv is multiply peaked, which should not be the case. The trace plot of the Markov chain Monte Carlo sample used to estimate the parameters reveals instability not only as to what Kv values are favoured but also as to with what combination of ECS and (indirect) aerosol forcing. In some sections of the plot it is not obvious that the combination of Kv, ECS and aerosol forcing values is consistent with conservation-of-energy constraints. In view of all these issues the ECS estimates from this study should be discounted.

Let's see, plenty of studies showing low sensitivity (about 1.0 degrees C) for DOUBLING CO2.
Yeah, that means going to 800 ppm. Which is just about impossible. (Hint CO2 atmospheric half-life is about 5 years; yes I have the references.) So all this is a tempest in a tea pot. What's really going on? U.N. "spread the wealth" socialists trying to steal our tax dollars.
