Magnitude matters. If you go out enough decimal places you’ll find an effect. Who cares? We are talking about something that would effect temperatures similar to what changes we see today, not milli-degrees.

The sun is fairly well understood. Feel free to hypothesize what mechanismninvthe sun could account for the period we observe on Wildrose’s graph. Scientists gave already chimed in saying orbital forcing and they have math and physics behind it.
All I have seen from you and Wildrose is words. Words from two people who have never studied astrophysics.

Adaptation … the action or process of adapting or being adapted. Putting on a coat when it’s cold is adaptation. Building a house and heating it with fire or cooling it with an evaporator is adaptation. Cutting down the forest and growing plants and domesticating animals for food is adaptation. Building dikes and pumps so that you can live below sea level is adaptation. Building reservoirs and aqueducts so that you can live on extremely arid ground is adaptation. And on and on and on. Man is the most adaptable species on Earth.

Yeah, we get it. Not your problem. It’s our and our kids problem. We’ll just pretend we are Dr. Who while the world burns and everything will be ok. Adapting and all.

The orbit variation is regular. If that were the only thing affect Earth’s temperature the line would be smooth with little if any difference during each cycle. Is the line on the graph between the cyclic highs and lows smooth? No. The sun has several cycles each with a different period that affect Earth’s climate much more frequently than orbital forcing. But even if those were the only other factors, the climate would be more regular. Obviously there is far more complexity involved, making the less significant factors and random occuring events (such as NEOs) less discernible, if not impossible to discern, particularly on such a compressed time scale.
In other words, you can’t prove a damn thing with that graph other than that a cyclic pattern of temperature has existed on Earth for the last couple million years or so.
I never said that was my theory, I said it’s a possibility.
What we know for certain is that orbital forcing alone cannot account for either the warming or the cooling in toto particularly for the Holocene period’s sudden cooling.
As for evidence what kind of evidence would be left unless there was an actual impact?
All it takes to alter temperatures by far more than we’ve seen rise in the last two hundred years is an extended period of cloudy days or a large volcanic eruption that can alter temperatures for years.
We havent’ got enough data from observation or measurement to really know anything about any long term cycles the sun may go through. Most of what we “know” about them is pure theory that isn’t based on any actual evidence. It’s assumptions built upon assumptions.
They are completely relevant if you’re going to claim that man is responsible for the warming of this cycle.
If man is indeed responsible we should be seeing a significant difference from the previous cycles.
I will point out that no new event is required for each new cycle. Anyone ever study the basic response of an undamped system that has had an initial but non-eternal forcing function applied to it? It oscillates.
Ponder that, libs.
What we need now is for one of the real smart libbies to point out that there are no springs on the earth… along with their hardy LOL at the moronic low education of this conservative for suggesting that the spring - mass model is remotely relevant.
Actually it is very simple, the climate on our planet is truly effected by these things. Our reflectivity to the radiation of the Sun, meaning our color, our cloud cover and what not on any given day. The amount of off gassing happening in our atmosphere, our distance from our sun in our given orbit at the time in our elliptical orbit around it which does change through the years, and our geometric angle from equator through out the years. That is what effects our surface temperatures. It has nothing to do with natural gasses at saturation in atmosphere other than off gassing. If you would all like to see the somewhat simple real math, I would be happy to provide it.

N. Fairfax drive has grown out of control.
I lament that the prosperity of Ballston has chased some of the really good Mom&Pop places out. There are still a couple of stand-out places a few hundred yards out of the commercialized space.
They have people making good money and working long hours. Good eats and drinks are a must.

Are you of the opinion that volcanic activity or cloudy days raises temperature and occurs in a cyclical pattern every 100,00 years?
Focus. We’re looking for explanations for the graph you provided.

We are talking about warming though.
Here’s some good reading:
The Holocene Climate Optimum (HCO) was a warm period that occurred in the interval roughly 9,000 to 5,000 years ago BP, with a thermal maximum around 8000 years BP. It has also been known by many other names, such as Altithermal, Climatic Optimum, Holocene Megathermal, Holocene Optimum, Holocene Thermal Maximum, Hypsithermal, and Mid-Holocene Warm Period.
The warm period was followed by a gradual decline, of about 0.1-0.3 °C per millennium, until about two centuries ago (when this trend was rapi...
Nothing in there about NEOs.

It’s not my area of science but there are gravitational fields at play here. Rock orientation, tides…I don’t know but something that effects our orbit substantially probably would leave a record. I could be wrong.
Borgia

First off, what mechanism are you proposing and providing evidence for that accounts for the warming?
Second, will it account for the much higher rate of warming today than we observe in previous cycles?
Third, are you claiming CO2 is not a greenhouse gas?
Fourth, you haven’t shown that orbital forcing cannot account for the previous cycles.

Are you saying there is no greenhouse effect?
