Re: Climate Science Special Report
But what does this have to do with the amount of carbon being released into the atmosphere?

One of the negative effects of climate change is a decrease in crop production, i think it is still whitin the lines of the topic at hand.

What are the Christians gonna do to me ..... Forgive me, good luck with that.

I am asking the opposite. What impact does crop production have on climate change?

The only large impact I am aware of is the clearing of natural habitats to make room for farms. Natural habitats, like prairies or rainforests, are natural carbon sinks since they bury plant matter. That is the irony of Brazilian ethanol production. Ethanol may be a renewable fuel, but they are clearing massive tracts of rainforest to grow crops for ethanol production and this results in a loss of carbon sinks. They will have to grow corn for decades or even centuries (relative to burning fossil fuels) before they break even with respect to their impact on total carbon in the atmosphere.

Growing crops in areas already cleared for urbanization may help a little, but then you run into problems of water usage and economy of scale. The amount of energy used and carbon released in urban farming may actually exceed those on large farms which makes it a wash.

Re: Climate Science Special Report
All that is the bad news. The good news is that plants take in CO2 and put out oxygen, and that enough of them, such as form a rainforest, create their own rainfall. Surely it's possible to plan to maximize the good effects and minimize the bad ones. Discouraging meat eating and encouraging plant eating is one place to start.

Im guessing its more then just choping down the lungs of our world, if you irrigate you increase the evaporation rate of water in a region and we irrigate so much some grate rivers dont make it to the see anymore. Apart from water vapour being a greenhouse gas that helps increase the temperature of our planet we are probably also changing rainfall patterns this way.

Using weed killers on such a scale that everything around your crops is brown earth decreases the albedo of the planet. Warming it further.

And of course transportation, we have a law that any food has to have a declaration of its origin, we get food from all over the world essentially brought to our homes, meaning we burn a lot of fosil fuels to get it there warming our planet even further.

Edited by frako, : decreases albedo not increases LOL

Evaporation has a cooling effect.

The problems of both weed killers and transportation costs would be decreased if personal gardening got popular.

Long term, with the right planning, even rivers and rainforests can be restored.

Yea as in sweat transfers heat from your body to the atmosphere not out in to space, away from the earth.


Think monkey think

Sure but not to some high degree.

Long term, with the right planning, even rivers and rainforests can be restored.

Sure the right planning would be kill of 4 billion humans and the earth will start to heal itself. Sure we could have taken the soft aproach by limiting births per person or even softer taxing those with more children, but we dont have the time to do it now. We have to produce more and more on an exponential scale to meet the demands of so many people, by the time such measures would have the any effect the world would alredy be 2 degrees warmer and still warming do to the fact that we are increasing the "insulation" of earth faster then it can warm up.

Water vapor only has a 2 week resident time in the atmosphere, so I don't think there are any long term climate changes due to irrigation. Also, the lungs of the Earth are the oceans where marine organisms make most of the oxygen we breathe.

Using weed killers on such a scale that everything around your crops is brown earth decreases the albedo of the planet. Warming it further.

For those of us who live in the Great Basin (a high desert region in the western US) that doesn't carry much weight. The land would be brown with or without weed killer. If anything, agriculture has greened the area and reduced its albedo.

And of course transportation, we have a law that any food has to have a declaration of its origin, we get food from all over the world essentially brought to our homes, meaning we burn a lot of fosil fuels to get it there warming our planet even further.

It's hard to eat food if it is hundreds of miles away. The question is if less efficient small farms burning more fossil fuels is a better option.

Weed killers aren't a problem for climate change, and smaller farms would burn more fossil fuels than larger farms per unit of food. Urban farming is even less efficient at food units per acre.

Health effects aside, eating lower down in the food web would reduce the amount of land needed for agriculture. There is about 90% energy loss at each ecological level meaning that we only get 10% of the energy from meat that we would have received from eating the plants the animals ate. We could feed a lot more people if we fed those veggies to humans instead of cattle.

Long term, with the right planning, even rivers and rainforests can be restored.

There is always going to be a struggle between growing food and preserving habitat.

Hektar or 10 ars LOL or 0,5 ha is 53819.55 square feet.

Or in English: 0.5 hectares = 1.24 acres

I can tell that 1 ars = 1,000 square meters, but what does "ars" stand for? Did you mean "are", which I've never heard of before just now using Google, but 1 hectare = 100 are, not 10 are, so I'm not sure what you mean.

I think most climate change deniers fail to realise by how much we have increased our co output just the past 30 years.
