You're right, they don't. Sedimentary analysis as part of reconstruction of past temperature in the Arctic (not just sediment, but ice cores, tree rings, and other assorted proxies) show that we were progressing towards another ice age. But that stopped when humans began influencing the planet...

So when the earth is expanding, how should it interact with the rest of the solar system? The gravity model provides a method for predicting outcomes. Using an electric model, what would you predict to happen if Earth expands?

So, what should happen to the supposed expanding Earth if the electric Universe hypothesis is true?

Under 40°C is what is needed for 100% bark beetle mortality. You don't need 100% bark beetle mortality to contain the spread of the species. But you do need it when other factors are changing. Warmer growing seasons has expanded the habitat that the beetles can invade, and it also speeds up the...

Ever had someone walk in-between you and a campfire DB? What happens when someone moves between you and the source of radiation?

Yes they are. They're used to test all sorts of hypotheses, by incorporation of many laws of reality. If a model produces repeated results under a set of conditions, and responds in a predictable way when you perturb it, then it's valid evidence, under the assumptions that the model uses. If...

Udder bull $hit. The mechanism is well known. Temperature regulates the metabolism of many infectious diseases, either directly, or through the interactions of vectors, and pathogen-host related metabolic activity. Show some skepticism Walt. Oh, by the way some trivia for the readers; the...

No, Pachuri gets it alright. Mann and Jones can't stop a paper from being peer reviewed, unless they are the editor assigned to the paper during the review process for whatever journal the investigation is attempting to publish in. The IPCC selects papers that are already peer reviewed. They can...

It's burps, not farts. A cow can produce about 500-600 litres a day. That volume is substantially smaller if the cows are grazing rather than fed corn and soy, which is foreign to the evolution of their digestive process.

Ahh. Well right now the flux of freshwater is most dependent on temperature. Precipitation moving around still ends up back in the ocean, I think precipitation is roughly equal to evaporation. The melting ice is probably best thought of in a similar manner to fossil fuels. It's like liquidating...

I'm not sure I understand what you're asking about. Do you mean for albedo effects? Or precipitation effects on freshwater fluxes?

It's not that simple. Increased melt water in the Northern Hemisphere is offset by a warming Southern Ocean. Previous deglaciations show the Southern hemisphere warming before Greenland, which strengthens the formation of the North Atlantic deep water, while melt water from the Atlantic basin...

Tell me, how do you take an event like species extinction, and remove one of the factors which was changing during the period that they went extinct, and determine that there is one or two factors only that determine this outcome?

Here's a task for you, make a case for attribution in the climate system without a model. Solar, greenhouse, volcanic...if you want to attribute the changes, you have to use a model, unless you know of a spare planet we can experiment with. Go ahead. Google now. I'll wait. If you can come up...

But it hasn't happened this fast (not in a long time, not in a few hundred thousand years at least) and concomitant with ecological degradation (deforestation, heavy metals, increased sediment, eutrophication, depleted oxygen, ocean acidification, and alien species invasions, to name a few).

Fail. Nature is not a mechanism. I'm all ears if you can find a mechanism. Until then, I'm sticking with the mechanism which can explain it. Radiative physics...the greenhouse effect.

What mechanism?

And what is the mechanism?

JLM, you appear to know about declining biodiversity, why would you think that tampering with temperature would be innocuous? One degree is the difference between 99 and 10% mortality in trout eggs in a stream. It's the difference between a predictable food source showing up in it's regular...

How do you know that it isn't the politicization by conservatives that is BS? It has nothing at all to do with science. Many conservatives do side with the myriad of synthesis reports which cannot escape the conclusion of human influence, and they are attacked by other conservatives immediately...
