Global warming is real

[dantes]

What objects are you referring to?

@dantes

The odds of a rogue planet entering close enough to have any effect on our orbit is infantessimally small.

If it is in our solar system and is big enough to affect our orbit, we would know by now because it’s gravitational effects would be seen.

Wrong. Those planetoid sized objects recently found in the outer solar system were found visually, their gravitational effect has not been measured.

@dantes

Please show me where you got that “large planetary fragments” are “relatively close”.

Nothing abrupt “happened” two million years ago. The climate has been shifting for millions of years and becoming less stable overall. The changes have been extremely gradual.

Earth’s climate was relatively stable for many millions of years up until about 2 million years ago when the current cycle of ice ages and brief interglacial periods suddenly began. Explain that.

[dantes]

No. They didn’t suddenly begin. It developed over a period of hundreds of thousands of years.

[Samm]

@dantes

Still going with the idea that ice ages didn’t exist before now? They have. There have been at least 5. There was nothing more localized about the Karoo ice age than any other glaciation. Why they occur has to do with ocean currents, land mass distribution and evolutionary developments.

Sorry, but a planet orbiting a star 50 light years from earth isn’t really a concern to our climate. A 200 m comet from interstellar space is not a concern to our climate. A moon orbiting Jupiter is not a concern to our climate.

It is if it’s on a highly elliptical orbit that brings it through the inner solar system every few million years.

[dantes]

That’s because those plantoids aren’t significant enough to affect our orbit.

Not wrong. Just read a little more carefully.

[dantes]

Then it isn’t orbiting another star 50 light years away.

Good gravy, what are we talking about anymore?

We don’t know their orbits. That won’t be know for years, until there are sufficient observations to make that determination. However, there is speculation that they may visit the inner solar system at their perigee.

Why you continue to dismiss this possibility is very unscientific. Regardless of the odds, that such objects are known to exist in our solar system that may be on highly elliptical orbits that would carry them into our neighborhood, leaves the door open to the possibility that they may be responsible for changes in Earth’s orbit in the past, and thus our climate, and could do so again in the future.

You made up the 50 light year thing. We were talking about planetoid sized objects orbiting our own sun. Good gravy indeed.

[dantes]

Another poster put up a list of exoplanets up to 50 light years away.

A reminder. Exoplanets orbit other stars. I didn’t make anything up. Maybe you should ask the other poster why they felt a list of exoplanets was relevant to the discussion because I sure couldn’t figure that one out.

[dantes]

I know the odds are extremely small. You to focus on what’s relevant and what’s known.

Again, you guys seem to be trying very hard to come up with something that cannot be proven or disproven.

Still waiting for you to show me evidence that we discovered objects without a known orbit.

I am not “other posters.” You and I cannot have a coherent conversation if you keep moving the bar. We were talking about objects either within this solar system or moving through it, passing close enough to Earth to slightly shift its orbit over the last 4 billion years.

If it is possible … which it is … it is valid to discuss. And that is what we are doing. We are NOT focused on it, we are discussing it with you … or at least we are trying to. You have been steadfastly dismissing it without discussion.

But why have you continued to ignore my question regarding the change in global climate that occurred some 2 million years ago? Isn’t it plausible that it could have changed due to a slight change in the obit around the sun?

[Call_me_Ishmael]

@dantes

Over billions of years, the likelihood of a non-random distribution goes down.

Because… ?

[dantes]

If you want to have a coherent conversation then I suggest you not interject into conversations being had with “other posters” as you did. Also don’t accuse me of making up anything when I didn’t bring it up in the first place.

I have yet to see any evidence suggesting such an object presents anything more than a minute, nearly non-existent possibly.

[dantes]

I didn’t ignore your question. I answered it a while ago. You must have missed it.

@dantes

Don’t know exactly what initiated the last ice ages. Previous ice ages were likely precipitated by plate techtonics. Perhaps the joining of north and South America changed ocean currents enough. Also the fact that there’s twice as much land mass in the north might have something to do with it. Ecology could have an effect too but it’s hard to say there was any substantial evolutionary changes unlike when Cyanobacteria evolves and precipitated the Huronian ice age

I reject the notion that there was any abrupt change and have posted the data which shows it was extremely gradual.

The mechanisms you propose seem extremely, extremely unlikely based on the information I know.

Should we discuss all possibilities? What if aliens moved the planet further away from the sun? Sorry but I don’t find wild speculation to be very scientific.

Still waiting to hear more about these objects with unknown orbits.

@dantes

Regression toward the mean

And that is stronger than the trend towards entropy?

[dantes]

Explain what role you think entropy plays in this discussion.
