Land use change as a driver of Climate variation
Dec 21st, 2016 at 12:03pm
 
http://www.skepticalscience.com/land-use-and-global-warming.htm

In Lee's latest contortion he is stating that it is changes in land use rather than Gas concentration which is driving climate change.

Please follow the above link for a more detailed explanation of how this has been considered by the scientific community, and why it has been discounted as a potential cause of climate change.

If you have any credible research adding credence to Climate change caused by land use(other than the discredited study included in the above link), Please feel free to post it..-this includes you Lee.

Climate change humbug?
82,000,000 barrels of oil consumed every day, 50,000 plant animal and insect species wiped out every year, 80,000 acres of rainforest leveled per DAY, 90,000,000 tons of fish being extracted from our oceans per year.
How can this possibly have any long term effect.
Its a bit of a gamble without another planet to go to.

Skeptical Sciene? Cheesy Cheesy Cheesy Cheesy Cheesy Cheesy Cheesy Cheesy Cheesy

'How does land-use change affect climate change?

Land-use change is one type of human activity that is causing changes in Earth’s climate. This excerpt, taken from the World Meteorological Organization’s website gives a short explanation of how land-use change alters the climate system:

“Land-use changes (e.g. cutting down forests to create farmland) have led to changes in the amount of sunlight reflected from the ground back into space (the surface albedo). The scale of these changes is estimated to be about one-fifth of the forcing on the global climate due to changes in emissions of greenhouse gases.'

https://www2.usgs.gov/faq/node/5601

So when you stand under a tree is it cooler or warmer? Is open land warmer or cooler? If it is warmer more heat gets reflected.

' In his Perspective, Pielke discusses results reported in the same issue by Feddema et al. in which changes in land cover--for example, from agricultural development--were included in climate simulations. One result of the simulation is that conversion of forest to agriculture in the model in the Amazon region leads to local temperature increases comparable to that simulated as being due to the radiative effect of the addition of carbon dioxide into the atmosphere.'

http://science.sciencemag.org/content/310/5754/1625

But apparently, according to SKS, there is no effect. Grin Grin Grin Grin

Are you Retarded?

You've posted links to two reputable, credible documents, neither of which supports ANY of the points you have made on this forum.

Not only that, your massively distorting(surprise surprise) the actual findings of the paper your referencing.
The paper finds that some locations(dense biospheres like the Amazon) can have a significant impact on climate when cleared. It also finds that only about 1.5 % of the planet would actually respond this way. The other 98.5%(inc 70% water) would only be slightly affected. And this is all based on model with forcings which in your own words


lee wrote on Dec 20th, 2016 at 3:13pm:
All of them rely on models. Models that have a number of "forcings" or parameters.

The output of these models is not empirical data. They are a function of whatever is introduced by these parameters. Change one parameter and the output changes.

'
    With four parameters I can fit an elephant, and with five I can make him wiggle his trunk.'



Just in case you missed the second classic Lee moment, its the little part after the bit he likes that kind of supports his position. Somehow even though the document clearly states that GHG have 4 times the effect as land clearing, somehow its land clearing which is the bigger factor  Shocked

Since were talking about climate change why don't you gimme some credible data that doesn't say that 80% of the worlds forcing is created by C02.
And that global warming isn't anthropogenic.

And stop misrepresenting research that disagrees with your fundamental premise as somehow supporting your case.

Once again you distort what I wrote. Land use change is one part of global warming. CO2 is postulated to be another. I never ascribed a ratio to either. Are you being wilfully ignorant?

What a dick. Completely distort what I write. Does it make you feel good?

The null hypothesis is what needs to be proven wrong. Do it if you can.

Ill try this again Lee. If you post a scientific paper which you state supports your view, you cannot just pretend parts of it don't exist when they disagree with you opinion.

The "material" you posted ascribed a ratio of carbons power as a heating agent in relationship to land clearing.

Because YOU posted this extract, i'm allowed to hold you to it. If you dont like it dont post it in support of you opinions.


I note that you didn't mention GHG's emissions as a possible cause of climate change when I asked, even though everything credible you have linked to concludes that they are primary driver.

You just don't get it do you. It is the alarmists who have to disprove the null hypothesis. As I have previously said some of the gloal warming is anthropogenic. Think land use change. Wink


Its like your.........just trying to make everyone stupider. And that upsets my sense of balance.

Ok. So 1/5 equals 20% - land use change

16% is natural forcing - Plants

We have admitted Internal Variation - no percentage.

So we have known warming non-anthropogenic of at least 36%, without Internal Variation.

So how did you come up with anthropogenic CO2 causes 80-85% of  warming?

If you posted documents that SUPPORTED you assertions you would make a much better fist of debating.

The problem with being a contortionist is sometimes you bite yourself on the ass!

I know. I quoted their findings that 80-85% of global warming is caused by GHG's.


It went straight over you head though, I was actually arguing against you with your own references.
