No, they are not guesses if by guesses you mean random numbers selected wtihout cause. Temperature estimates are based on data and physical laws.
LOL!!!
No, they are based on this

So you believe that tree ring width, ice cores or pollen can tell you what the temperatures were? You need to get your money back for whatever education you've received.Not true.
They do it with everything from comparative Tree Ring width, to Ice Cores to (and even the types of pollen) even WAY further back than that.

No "ice core" can tell you what the temperature was LAST YEAR, let alone what it was 10,000 years ago.What's the hottest Earth's ever been?
Earth’s hottest periods occurred before humans existed. Those ancient climates would have been like nothing our species has ever seen.www.climate.govHow Do We Know The Temperature On Earth Millions Of Years Ago?
How do scientists and researchers talk about the climatic conditions thousands or even millions of years ago? How can they tell what the temperatures of Earth were in the ancient past?www.scienceabc.comHere's How Scientists Reconstruct Earth's Past Climates
Scientists apply different methods to the geologic record with the goal of better understanding and quantifying ancient Earth's temperatures.www.smithsonianmag.comHow do we know how warm or cold it was in the past?
Temperature records go back decades and earlier periods can be examined using 'proxies' sources such as ice coreswww.theguardian.com
Do you have any idea how it's done? I'm going to assume you know as little science as it seems. Not all atoms of the various elements have the same number of neutrons and thus the same weight. The different 'vesions' are known as isotopes. The ratio of heavy to light isotopes of oxygen (which is in all water (H2O)) changes with temperature. So by examining the ratio in the ice in an ice core, we can tell what the temperature was when it was first lain down. You will sometimes see it graphed as simply the O18 (the heavy oxygen isotope) level. So, it is indeed possible to determine local temperatures from hundreds of thousands of years ago from ice cores. The limitation is that it is the temperature of just the location of that ice core. It doesn't tell you the temperature anywhere else around the world. What it does tell you is the long term temperature trends which, for the most part, mimic the trends from around the world: up, down, fast, slow, etc.No "ice core" can tell you what the temperature was LAST YEAR, let alone what it was 10,000 years ago.
And his error about the Nobel Prize awarded to the IPCC for whom he was a principal author, how did that affect you personally, Todd? Is THAT why your reject mainstream science? Is that why you believe in that massive, perfect conspiracy?
what's really funny to me is that gardening showed how well plants do in a greenhouse, and the warmers are trying to remove the CO2 needed in them to kill them all. Why do you want plants to die?Right away, I have to call bull shit. Your statement is not a fact: CO2 also has been proven to reflect energy back into space. It would take less than a 2% error in the mathematical model used in some of the theoretical calculations to reverse the scenario.
There has also been little observed change in tropical average temperatures. The majority of temperature change has been observed in northern, temperate, regions. This indicates that the theory that a larger, more robust, more NORMAL atmosphere (as opposed to the sickly, glacial period atmosphere) with higher CO2 will act as a blanket, fostering better growth in northern latitudes as well as tropical regions (tropics may actually be moderated due to the insulation effects).
In other words, we are getting ready to see Northern Africa become a vibrant powerhouse of vibrant life. This may take hundreds of years, but you have to stop thinking in terms of your own minuscule life expectancy in order to see the full picture.
Question for thought: Why was Egypt such a huge global power 3000 to 4000 years ago? Was it because of dry sand? Could it be that there was something else going on, and the mini-ice age we recently experienced put an end to it? Could it be that as the atmosphere heads back toward a more normal (geologically speaking) composition that we will see changes in weather patterns?
These charts do not help your case about any reason to fear CO2, my friend. Map the timeline to known archaeological discoveries as far as plant and animal fossils.
Again, these charts do not show a cause-and-effect pattern, although they do show a correlation.
I will say it again: Mankinds use of fossil fuel is part of God's plan, and we have rejuvenated the possibility that life on Mother Earth will flourish again as it has in the past.
There is no reason to fear CO2. There IS reason to celebrate at the prospect of having an abundance of carbon available for life to flourish.
Thanks!
BS on a shingle. Oxygen isotopes do NOT appear or disappear magically when the temperature changes. Are you REALLY this ignorant or is it an act of some sort?Do you have any idea how it's done?

"I'm too goddamn stupid to understand the basics, so it must all be a hoax" is not an argument. It's an evasion by a gutless cult crybaby who is too much of a wimp to admit that he knows nothing about the topic, and that he was just parroting the brainwashing he had received from his cult.BS on a shingle.

ok demfk, can two CO2 molecules in the atmosphere warm each other or cool each other?"I'm too goddamn stupid to understand the basics, so it must all be a hoax" is not an argument.

And that's all you've given us.
Back to the kiddie table with you, child. You shouldn't be bothering the grownups.
They can only warm each other. It's possible an IR photon emitted by one could strike the other.ok demfk, can two CO2 molecules in the atmosphere warm each other or cool each other?
Why would you think they get warmer on their own? An outside heat source is required for that. And there is one. It's called "the sun". Do you understand that something called "the sun" exists?And if you added another 10 million? Those CO2 molecules get warmer?

They can't cool each other.
This is basic stuff. Why did you have to ask about it?

Did you have any actual point to make with these stupid questions, other than to show how very butthurt you are? If you did, you should state your point clearly and directly. You know, like a liberal would.
Is AGW a Theory?
We can test the behavior of CO2 in a laboratory.
Is there any dispute that humans are putting CO2 into the atmosphere?
You’ll never know. You’ll be dead. But, because you deniers don’t give a fk what happens for you dependents, you forfeit your right to be considered anything but a joke.What if we don't hugely cut our emissions and warming slows or stops?
Yes there is, among the dullards. We’re here just to remind them, they ARE dullards.Is AGW a Theory?

We shut the global economy for 2 years and CO2 still roseWhat if we don't hugely cut our emissions and warming slows or stops?
China emits double our CO2 and one river in China dumps more plastic into the ocean than the entire USA. Chain yourself to the nearest Chinese EmbassyYou’ll never know. You’ll be dead.
