Even if emissions stop, carbon dioxide could warm Earth for centuries

Sounds like Brazil's problem. Maybe they would be best pursuing policies that make deforestation in their country not worth the effort.

On the other hand, when timber is treated as a renewable cash crop, as it is in America and elsewhere, there's no money in deforestation without replanting.

One motivation for clearing those rain forests is that American Beef has gotten so expensive (because of corn prices) that we cannot compete for export. And places like Brazil are filling the vacuum.. IN FACT --- the fast food industry in the US is IMPORTING more and more "rainforest beef" every year..

Gee THANKS enviro-nuts.... ANOTHER unintended consequence of your "plans"??

Would you care to explain how US environmentalists are responsible for Brazilian clear cutting in favor of raising cattle?

And as far as corn and cattle feed:

Different cattle feeding production systems have separate advantages and disadvantages. Most cows have a diet that is composed of at least some forage (grass, legumes, or silage). In fact most beef cattle are raised on pasture from birth in the spring until autumn (7 to 9 months).[citation needed]Then for pasture-fed animals, grass is the forage that composes all or at least the great majority of their diet. Cattle fattened in feedlots are fed small amounts of hay or straw supplemented with grain, soy and other ingredients in order to increase the energy density of the diet. The debate is whether cattle should be raised on diets primarily composed of pasture (grass) or a concentrated diet of grain, soy, corn and other supplements. The issue is often complicated by the political interests and confusion between labels such as "free range", "organic", or "natural". Cattle raised on a primarily forage diet are termed grass-fed or pasture-raised; for example meat or milk may be called grass-fed beef or pasture-raised dairy. However, the term "pasture-raised" can lead to confusion with the term "free range", which does not describe exactly what the animals eat.

You really don't KNOW that much of the rainforest destruction is to clear land for McDonalds? What kind of environmentalist are you? I can't fill all the gaps in what you know. Go look up rainforest beef Brazil

Our cattle industry AND the rainforests are DIRECT VICTIMS of enviro MADNESS driven by your minions of morons pushing for biofuels..
 
Whether or not they are being paved over is irrelevant, particularly in the tropics, such as Brazil. The soil is so poor there that once you cut down the forest, every little will grow back.

Just like the huge dead zone in the Gulf of Mexico that's caused by environmentalists.

I'm not even convinced they mean well anymore.

If they truly meant well, they would recognize the harm they have caused and cease their foolishness.
 
You all missed the major point there. Cattle are primarily fed grass, not corn. The ethanol program has not driven cattle production to Brazil. McDonald's might have, but McDonald's is not the responsibility of American environmentalists, is it.
 
Another reason to get away from coal is it causes cancer.

Is that a better reason for you?

Name a person whose death certificate says Cause of Death: Coal.

You can categorize that nonsense with the second hand smoke hysteria, which has never killed a single person either.

No. The CO2 in the atmosphere will be there for a great long while. But so will the CO2 we put there ten, fifty, a hundred years from now. We need to take serious action, NOW, to reduce our GHG emissions.





The residence time of CO2 is at maximum, 15 years. Try again silly person.
 
The difference between the height of the little ice age and today is around 2c.

The difference between those mile high glaciers over Chicago and looking up at them on staten island is around 8c.

2c in 100 years is a oh shit moment!





What was the temperature BEFORE the LIA began? Have we even got back to that level yet? The paleo and historical record says no, we haven't.

Chicken Little lives.

Tell me exactly what will happen. You can't. You can't even say with any certainty that the 2 degree prediction is accurate.

The fact that the GW crowd keeps upping the ante tells me they don't know what's going to happen. But the more they scare you the more you can be controlled.

First of all, we cannot say 'exactly' what will happen. But we can say that it will not be good for a population of over 7 billion humans that depend on a stable climate for food. And that 2 degrees figure is an optimistic one, one that does not consider the feedback effects we are seeing in the Arctic.







Who depends on a "stable climate"? The climate has NEVER been stable no matter what propaganda you try and spew. Further, doing nothing, the population is going to continue to rise to perhaps 9 billion and then drop back down to around 6 billion.

Does it make you comfortable knowing that we can't predict all the effects? If so, why?





If you can't predict it, you can't measure it. If you can't measure it, it's not scientific. It's PSEUDO-SCIENTIFIC.

Any concern they may have had has been trampled down by their need to control individual lives with the threat of government violence.

It's what progressives always devolve into, if allowed. Always.

No, the ethanol program is killing the Gulf of Mexico.

I bring that point up in many environmental threads. It NEVER gets acknowledged by leftists.

Maybe you can be the first...?

But it's so EVIL and POWERFUL, it still keeps making the planet warmer! Just like it's so EVIL and POWERFUL, it goes back in time to raise temperatures CENTURIES before it's released!

EEEEVIL!!

Ask him what the "correct" temperature of the planet is. :lmao:

Which is no response at all.

We are putting it into the atmosphere faster than its coming out (and most what comes out only goes into solution in the ocean). It WILL be a great long while before that is not the case. My statement is correct. Silly person.

In the IPCC 4th Assessment Report glossary, "lifetime" has several related meanings. The most relevant one is:

“Turnover time (T) (also called global atmospheric lifetime) is the ratio of the mass M of a reservoir (e.g., a gaseous compound in the atmosphere) and the total rate of removal S from the reservoir: T = M / S. For each removal process, separate turnover times can be defined. In soil carbon biology, this is referred to as Mean Residence Time.”

In other words, life time is the average time an individual particle spends in a given box. It is calculated as the size of box (reservoir) divided by the overall rate of flow into (or out of) a box. The IPCC Third Assessment Report 4.1.4 gives more details.

In the carbon cycle diagram above, there are two sets of numbers. The black numbers are the size, in gigatonnes of carbon (GtC), of the box. The purple numbers are the fluxes (or rate of flow) to and from a box in gigatonnes of carbon per year (Gt/y).

A little quick counting shows that about 200 Gt C leaves and enters the atmosphere each year. As a first approximation then, given the reservoir size of 750 Gt, we can work out that the residence time of a given molecule of CO2 is 750 Gt C / 200 Gt C y-1 = about 3-4 years. (However, careful counting up of the sources (supply) and sinks (removal) shows that there is a net imbalance; carbon in the atmosphere is increasing by about 3.3 Gt per year).

It is true that an individual molecule of CO2 has a short residence time in the atmosphere. However, in most cases when a molecule of CO2 leaves the atmosphere it is simply swapping places with one in the ocean. Thus, the warming potential of CO2 has very little to do with the residence time of CO2.


CO2 has a short residence time

And you are a liar.

Common Climate Misconceptions: Atmospheric Carbon Dioxide | The Yale Forum on Climate Change & The Media
It turns out that while much of the “pulse” of extra CO2 accumulating in the atmosphere would be absorbed over the next century if emissions miraculously were to end today, about 20 percent of that CO2 would remain for at least tens of thousands of years.



Fig. 9a: Decay of a small pulse of CO2 added to today's atmosphere, based on analytic approximation to the Bern carbon cycle model
(Joos F et al., An efficient and accurate representation of complex oceanc and biospheric models of anthropogenic carbon uptake, Tellus, 48B, 397-417, 1996; Shine et al., Alternatives to the global warming potential for comparing climate impacts of emissions of greenhouse gases, Clim. Change, 68, 281-302, 2005, see equation given in figure).
In this approximation of the carbon cycle,

Residence Time of Carbon Dioxide in the Atmosphere

about 1/3 of the anthropogenic CO2 emissions remain in the atmosphere after 100 years, and
1/5 after 1000 years.
