If you believe AGW is a hoax, explain how and why we can have a conspiracy of most climate scientists, in all countries, in many regimes, lying for decades???
For what reasons?

Name the top climate scientist in the world who you believe understands why we're going to fry if we don't cut back on our co2 emissions.

I was looking for a better word than fry to explain all of the fear and loathing of the future our indoctrination system has instilled in our youth. We will see more and more pathetic cases of Greta until we expose these pseudo-scientists for the frauds they are.

So who's the top guy so we can look more closely into his models and data?

Climatology is a fledgling field that has hardly been developed. The problem with most science and other fields of academia is that they try to piggy back on the reputations of fields like Physics, where we can put together 20 textbooks on various fields within the subject, 1000 pages long, and it will never have to change...because we know the subject in and out. Climatology is not like that...and likely never will be.

The very few that are out there are suffering from massive groupthink and stepping beyond their bounds. This idea that warming creates substandard living conditions hardly has any basis in reality.

Here's some scientific facts:

1. More people die from extreme cold than extreme heat....a lot more...like 17 times
2. Food production and industrial production has been positively correlated with warming the past 100 years.
3. Population growth has been positively correlated with warming the past 100 years.
4. The planet is actually greening due to climate change....which was confirmed by a group that studied satellites at the Liberal UC Berkeley.
5. People don't flee warmer climates...they flock to them.

20 years and still no hockey stick.

Sorry, 1 degree C in 50 yrs is a hockey stick.
If you project it, it's a dramatic climate change in 100 yrs, which is a blink, even relative to the history of mankind.

theoakman says

5. People don't flee warmer climates...they flock to them.

Quite frankly this is a totally ridiculous.
We are in a situation now where population is booming, because of the same civilization that causes warming.
Population is dense enough in many areas that the slightest storm often kills one or more person. A large storm typically kills dozens.
The slightest drought in underdeveloped countries can kill thousands. We are NOT talking about large disruptions. People are killed easily.

At the same time, the population is large enough that we are overshooting many of the environment variables. Most fish species worth fishing are over-fished. Soils are eroded. Water tables are running out.

And we're just about to add 3 fucking billions .

Add to this a large disruption like changes in climate and the result will not be "people flocking to beaches in Florida." It will be famine, pestilence, wars and death.
If uncontrolled, and you get 2, 3, 5 degrees C increase, this will overwhelm in at least some places the capacity of populations to adapt. You will see order collapse resulting in chaos, and more problems.
Quite obviously this needs to be addressed and the sooner the better.

theoakman says

That's a ridiculous statement. So engineering is piggy backing on physics? The complex models of air flow around a plane is "fledging" because it is complex and applied rather than canonical theoretical physics?
Modeling climate effects is direct applied physics.
Ballparking the changes is a simple consequence of the laws of physics. You prevent heat from leaving... temperatures increase. This is fucking direct causality. There is no known effect that will prevent it. And there is a ton of empirical evidence that says it is happening.

Alarmist's claim that "97% of climate scientist say climate change is real, manmade, and it's going to be catastrophic", but when you ask them who these scientist are... nothing.

"Alarmist's claim that "97% of climate scientist say climate change is real". This kind of 'proof' works for anything.

1. More people die from extreme cold than extreme heat....a lot more...like 17 times

And given that the higher, colder latitudes where this occurs are much more sparsely populated than the warmer hotter latitudes, the ratio would get even larger. Say, if you divided population density by cold weather deaths and compared it to population density divided by hot weather deaths.

I’m betting that it would be more like 100x more people dying per capita from cold than from heat.

I used to live in Alaska. The cold up there can kill you in a very short time, and many people do perish each year due to the cold, and their insufficient preparation to combat it. I’ve had hypothermia twice, and had more than a few close calls with cold weather survival. I learned very early that you either account for the weather or it will kill you.

At the same time, the population is large enough that we are overshooting many of the environment variables. Most fish species worth fishing are over-fished. Soils are eroded. Water tables are running out.

This is the real issue, not "carbon." The solution is to allow the 1st Word population stabilize to a level sustainable by renewable food and energy sources, and stop imports from countries that have lax pollution or non-sustainable harvests. Note, however, that the same people banging the carbon drum are against these two solutions, instead pushing for unfettered illegal immigration and no tariffs on China.

You seem to think using the laws of physics in their models makes it accurate. It doesn't. I used to run month long quantum mechanical calculations on single molecules using supercomputers. The complexity of a system quickly invalidates the accuracy of the calculation. The Earth is too complex to model.

You can't predict a single molecule... yet you can pressure a body of gas and predict exactly what the equilibrium is going to be. You can predict exactly how heat will spread in a body of water and how fast it melts ice. I can even describe the trajectory of an entire fucking planet a year in advance down to the millisecond. Why? Because aggregate calculations are far easier and accurate at their level than the details they are made of.

Climate projections are about a million times more complicated than forecasting the melting of ice in a closed system w scientifically added units of heat.

Expecting the earth as a whole to follow these controlled experiments is the problem. Its scientific hubris to the highest degree.

An entire planet and it's trjaecotry is a single point mass. That's not complex. You are only further proving my point trying to take the accomplishments in Physics and project the. Onto a field like climatology.

You don't know. I don't know. But you don't know that I don't know. So, I can say that I know in order to control you, because you insist or believe that somebody knows.

CBOEtrader says

Climate projections are about a million times more complicated than forecasting the melting of ice in a closed system w scientifically added units of heat.

You assume a model doesn't account something a million time more complicated. This is a very simplistic view of what these models are. Just like the flow of air around a plane, these are incredibly detailed calculations.

theoakman says

An entire planet and it's trajectory is a single point mass.

No it's not. For example water is moving on this planet following tides. And the planet doesn't move in a constant gravity field: the gravity of the sun is slightly stronger the side closest to the sun, than on the side away from it. This means that using the center of mass is just an approximation. Not to mention other planets.

Yet you are very willing to ignore the details and admit I can consider the planet to be a single point for the purpose of predicting its trajectory, but you won't admit that the very simple aggregate fact that less heat is reflected in space means there will be more heat somewhere on the planet.

Heraclitusstudent says

Nothing was wrong with the models. They predicted a rise of temperatures and we saw a rise of temperatures. Models are never perfect but they ballparked efficiently what is happening. I.e. a problem that will be unacceptable in 100yrs unless we do something about it.

If a model predicts the Moon will be X Kilometers away from Earth at a given point in time, and it's 75% less distant from where you predicted it will be, the model is a failure and I hope no manned missions were launched using it's calculations.

By this standard we can't predict the human population on this planet in 2100: there's is way too many details we can't predict: will there be a world war? Will there be a dangerous pandemic? Will an asteroid hit earth? Will people decide to have kids? Who the fuck knows?

Yet we have very good projections of that number. Not predictions. Projections.
How do you explain that?

That's true, but for a different reason; trends change. If third world countries get richer - and as we discussed in another thread this is happening in places like Vietnam and India - the birth rates may radically change, making the numbers way off.

The conceit of the Global Warming Models is that they use scores of variables, many of which we can only take a rough guess at. The more rough guesses in a model, the more likely the result will be crap. And unlike most demographic projections, the math and often data is kept back.

I note that Mann drops every lawsuit after the judge demands he open his work to the Defense.

Heraclitusstudent says

How do you know they are very good?
Have you traveled to the future to verify their accuracy?
Seems to me that you’re taking a lot on blind faith in authority.

Heraclitusstudent says

Because aggregate calculations are far easier and accurate at their level than the details they are made of.

BUT, if your basic assumptions are wrong, increasing co2 increases temperature, your models will put out bad results.

Heraclitusstudent says

these are incredibly detailed calculations.

And they have been proven wrong by observation.

I've seen multiple projections anywhere from 1 degree celsius to 4.5 degrees celsius. This is a huge friggin margin of error... You can't claim accuracy with such a wide range of predictions. It's the equivalent of saying the 49ers will score anywhere from 10 to 45 points.

Still waiting for an alarmist to state who they think the top climate scientist is. Mann? Hansen? Gore? Who is the most respected? Out of 97% you must have a favorite.

and btw...you did say such a thing...."Modeling climate effects is direct applied physics. " It's also funny how you want to describe a system of planetary motion as more complex than a quantum mechanical calculation of a molecule that involves potentially hundreds of electrons in which you are accounting for both gravitational and electrostatic forces.

Nevertheless, all systems you described are highly ordered...other than the Earth....which is a sphere of absolute chaos. Climatology is hardly a developed science at this point. That does not mean we shouldn't continue to study it and improve it. Just stop giving it the credibility that it has right now because it hasn't earned it.

I'm more than willing to admit that global warming exists. I believe we are on track for a rise of 1 degree Celsius in the next century. I have yet to seen a compelling case as to why that would be bad for quality of life, viability of various species, and humanity in general. That case definitely hasn't been made....just assumed.

You think Trump is president now, right? How do you know it is correct? Maybe he was just assassinated and you don't know it yet. Mike Pence is president.
How do we know the cloudless sky will be blue tomorrow? Maybe the laws of physics will change...
Almost everything we know is induction. And almost all of it CAN be wrong.
If you wait that your knowledge is perfect, you will have to admit that you know basically nothing, and certainly you can't predict the most mundane fact about tomorrow.

So what justifies what we know? The reasons we have to believe that something is/will be true based on what we have observed so far. And these are probabilistic.

So how do we know population projections are good? Because demographic facts don't change very fast. Because we know in which directions things are evolving now. Because we know what are the chances of an asteroid hitting earth.
And sure they can be wrong. But based on how likely things are so far, we can estimate that we are very likely to be a certain range. It's a a range and it's very likely based on what we know.
And we refine that range as things get closer.

And for planning purposes, this is all we need. This is a very useful projection

Trump's Presidency doesn't depend on extrapolating current trends into the future.

A Presidency lasts a set time.

Just like I know a 90-day warranty is a 90-day warranty. Barring a massive disruption, I'll get 90-days to return the toaster.

That's different that projecting the Average Earth Temperature 10 years from now, which may not depend on a single mass disruption, but only a minor tweek of one of scores of variables, from sunspot frequency to the strength of El/La Nino/Ninas.

Yes it does. For at least a few minutes.

NoCoupForYou says

Massive disruptions can happen.

If disruptions don't happen then simple projections of empirical facts like "Trump is president" or "the currently observed warming" are likely to be correct.

It's an excellent example of how aggregate level is the sum of all complexities below that level, yet it is simpler.

Even if it is applied physics, multivariable chaotic systems are almost impossible to model; witness the "butterfly in China" effect.

The same effect applies to a 3 bodies problem with gravity, yet we are able to predict the trajectory of a planet 100 years in advance with good precision (and there are more than 3 bodies in the solar system).

People who use this kind of argument are doomsayers of the human spirit who refuse to admit we can know anything about the future, starting with basic facts such as adding heat to a system increases its temperature.

See....this is where you are wrong. Yes, the 3 body problem can be simulated and a solution is obtainable to 99.99999999% accuracy. The same for a 10 body problem. It just requires 10000 times more computing power. With respect to the work that I've done, organic molecules of carbon, hydrogen, oxygen, fluorine atoms..you are solving the Shroedinger equation for a 200 body problem. This takes months on a supercomputer....and you have to make all kinds of compensations or estimations in order to get the job to go to completion. This is orders of magnitude more difficult than modeling a solar system because you deal with electrostatic forces between each and every electron and proton along with the gravitational force.

As far as simulating the Earth....to realistically do it, you would need an infinitely complex model and knowledge of every moving part. There are too many floating variables....and by too many, I mean gazillions. So what do they make? A theoretical construct of the earth....consisting of land masses, oceans, wind streams and what not. You can name an infinite amount of sources of error and compensations they make to get their calculations done. It's akin to simulating the growth of a city in Sim City and drawing conclusions about NYC.

Needless to say, any projections that have correctly forecasted a running average of temperature increase are not that impressive. We know what the trend is...and yes....it's up. It's been a steady rate. The idea that the rate of warming is accelerating is not backed up by any meangful statistical evidence. If your model predicted at .2 degree increase... over the past 20 years....well whoooptie damn do. That doesn't make it good. You could have simply traced through the 100 year data and extrapolated out to that.

Actually, if you care to analyze my post....planetary motion is not more complex than solving the Shroedinger equation for molecules. But analyzing the climate in an entire plant is infinitely more complex than solving the Shroedinger equation...which is why...climatology modeling is hardly a developed science.
