Climate Change: Scientists Say "Last Chance"

Can we save a bit of time - is there anything that would convince you that humans are affecting global temperatures?
Not materially and not in excess of the effect on habitat loss and the loss of biodiversity. There are pressing and demonstrable environmental issues but MMGW isn't one of them and it's sucking away valuable resources that could be better employed.
 
Proof indeed that you are a troll on the matter.
No, a statement of the fact that there is no way to accurately sample anything from the period to provide an accurate database on which to model an accurate representation or simulation of what may have been. You are the troll, unless you can provide evidence of accurate paleoatmosphere reconstruction.
 
it’s because you don’t understand the theory. Previously there had been an external forcer, like a milankovitch cycle that caused the warming, followed by an increase in CO2. The theory now is that there is no external forcer, we have put a lot of greenhouse gases into the atmosphere and there is a warming trend.
You are saying that the sun no longer exists to warm the earth, therefore, people are now magically warming it. Got it.

You really are a fraud star.

Now now, you are educated enough to know about milankovitch cycles. And apparently very intelligent to completely discredit ice-core climate reconstruction.
Perhaps just not motivated enough to refute them in the academic journals.

The Milankovitch Cycle is the proven and accepted model that explains how the heating and cooling of the earth by the sun is effected by the earth's eccentric orbit around the sun. The sun IS the "external forcer." You are claiming an unnamed theory is now saying there is no "external forcer" and humans putting greenhouse gasses into the atmosphere is warming the atmosphere without that "external forcer."

The theory now is that there is no external forcer, we have put a lot of greenhouse gases into the atmosphere and there is a warming trend.
The Earth is still in its eccentric orbit around the sun, which still exists, and still forces Earth climate*, through its external heating of the Earth.

*and the climate of the entire solar system and a bit beyond.
 
No,

I am saying that the current warming trend is not explained by our position in the cycle.

perhaps it should have said extra forcer.

By you calling me a fraud for saying human emissions are changing the climate, you are also calling the met office, NOAA and NASA frauds as well.

Never having previously heard of the Miklankovitch Cycle I looked it up. This bit is interesting "In the 1920s, he hypothesized that variations in eccentricity, axial tilt, and precession resulted in cyclical variation in the solar radiation reaching the Earth, and that this orbital forcing strongly influenced climatic patterns on Earth. "
So Milankovitch hypothised the effects of orbital eccentricity etc. Granted analysis of soil, rock and ice samples are consistent with his hypothesis, but some things are left unexplained. So we have some of the picture, but not all of it. This is one reason why NASA among others is so interested in Martian and Venusian climates, both planets are similar to Earth, but the climates have gone to wild extremes. The question is why and what relevance does this have for the Earth?

You named yourself fella.
 
No - you're not as informed and enlightened as most of the posters on this thread. They are so much better. :)
PSA: If you experience Red Shit, you probably only have haemorrhoids and don't need a colonoscopy, but get checked anyway to be safe.

Being unpaid, I am not going to go into compulsive detail, but the reason it is proven and accepted is that the Earth's temperature fluctuations match Milankovitch Cycle predictions very well. What isn't included is basically impossible to include, like fluctuations in intensity of solar winds and energy outputs from the sun. There are many reasons why there is no way to sample space to get a record of that, not the least of which that actual space, where nothing relevant would remain to sample anyway, is already a long distance in the rear view mirror.

Man-Made Global Warming is what a 419 scam looks like if it's run by white blokes.

Ah yes, the great scam most governments, scientific institutions and universities have been hoodwinked by.

but not the clever conspiracy theorists, who just somehow haven’t managed to get peer-reviewed and saved the world.

You should by now that quite a few ARRSErs love a good conspiracy theory....

So stop bleating and crush us with overwhelming science... or not.

let me present evolution to you.

and how tobacco causes cancer

and why not crush us with all the governments, the universities, the academic journals, the papers, the organisations that all say that human emissions are not affecting the climate.
