Global warming :: is it just a 'chinese hoax' like trump told us or is it serious?

Makes no sense. They don't simply leave most of that plant matter to decay. It's inefficient. They clear those spaces to replant cash crops or to raise cattle. Piles of healthy timber would take forever to decay. Granted, it would decay much faster if mulched but still. There is some explanation missing from this. Are they measuring cow farts? Much of that deforested land is used to raise cattle. A lot is used to raise palm for palm oil.

Side note: Palm oil is fucking horrible for you and it's literally in so many things.

So this comes right back around to this post above. It's over population. Rain forests now adding CO2 the equivalant of the country of Japan because man is moving in. Stop all fossil fuels and CO2 will continue to rise it appears, maybe slower but still on the rise.

Good news other areas are taking up a lot of the slack. Agriculture is benefiting and taking in CO2. Northern forests are absorbing more. 

So why aren't we planting more trees? Taking great care of our forests? Seems like a logical priority.

Well, the burning accounts for some but is not as long-lasting if you assume a one-time event and not perpetual.

The decay will last longer and the soil release has to be factored in and the soil retention is then affected:

Changes associated with deforestation continue for decades after forest clearing eventually extend to deep subsoils and strongly affect soil functions, including nutrient storage and recycling, carbon storage and greenhouse gas emissions, erosion resistance and water storage, drainage and filtration. Reforestation reverses many of the effects of deforestation, mainly in the topsoil, but such restoration can take decades and the resulting soil properties still deviate from those under natural forests. Improved management of soil organic matter in converted land uses can moderate or reduce the ecologically deleterious effects of deforestation on soils. We emphasize the importance of soil knowledge not only in cross-disciplinary research on deforestation and reforestation but also in developing effective incentives and policies to reduce deforestation.

But the key thing is the loss of forest and its benefit overall.  The deforestation adding CO2 is not as big a deal to me.

Plus a lot of these lands are not used in agriculture afterwards.  Last study I saw showed huge amounts in Asia, Africa, and the Amazon that were abandoned, etc.

@StumpTownStu

A large amount of that land is not used.  It would, even so, be way less.

Decay for this amount would take a long period of time, even after burning lots of it.

It would be mostly cow burps -- surprisingly enough.  Most folks do not realize this. Haha!

This will explain some of the soil release of CO2 even in smaller areas.  So, imagine a much larger forest area.

Most aren't abandoned. Early South American deforestation had to do with the timber industry, as some of their lesser known hardwoods made great replacements for some of the more known Mahogany. Now many of those hardwoods are notable in their own right. Most large scale deforestation these days is for raising cattle, or for planting things such a palm for the palm oil industry. 

I mentioned this earlier. Decay of healthy timber takes incredibly long. I mention the possibility of cow farts. It sounds crazy but a lot of deforestation of tropical rain forests, specifically in South America, is to raise cattle.

@StumpTownStu

I am saying people say farts when it is the burps that contribute the majority of the cow's release.

@StumpTownStu

Yes, way more than you would think and for various reasons.  I think outside of America -- Asia, Africa, Amazon it is upwards of 25-30% of the deforested areas.  Very inefficient use there.

@StumpTownStu

Correct. Decay is a long ongoing process.  The burning is done quicker.  The the soil release has to be factored in.  I think Amazon was a net ~30% loss of Carbon in last 10-20 years or so.

But I am told that the efforts to slow deforestation has helped in a lot of places and it is getting better now.  Or, at least closer to what we consider 'normal'.

Even the non-abandoned areas are not used as efficiently as the forest was doing as well, in regards to absorption. 

More comical to say farts.

@StumpTownStu

Historical data shows carbon dioxide is both cause and effect of warming. As ocean temperature rises, carbon dioxide increases to amplify warming trend so that 90% of warming follows carbon dioxide increase in positive feedback loop. In pre-industrial age, carbon dioxide lags temperature. For example, climate change due to Earth orbit over thousands of years. However industrial age is different because carbon dioxide leads temperature.

@thirdperson

 Nonsense -- read up on this. 

Ability of forests to absorb carbon dioxide is declining because of deforestation.  Logging can turn forests into carbon sources because dead trees release carbon dioxide which remain in atmosphere for centuries.  Deforestation contributes 10-20% of global greenhouse gases  Over 100 countries have signed COP26 deal to reduce deforestation.

@thirdperson

 Yes.  We just discussed this.  Go back and provide numbers for your previous stuff. 

Headline: Texas power prices surge 6,000% as grid operator asks residents reduce energy usage due to 'low wind ' generation!

Only liberals believe that windmills and solar are the answer to our ability to produce energy and power. Fossil fuels and natural gas have been the answer to our energy needs. I don't want my heat dependent on the wind or the sun. 

The above statement is from a human being and is not racist in any way, shape or form.

According to Energy information administration, solar and wind energy have been a lifeline propping up Texas power grid.  Old plants which run on coal, nuclear and natural gas have gone offline as demand surges during the summer.  In 2020, wind power first surpass coal as second largest electricity source.  Since renewable sources are cheaper, they help to keep electricity prices low.  Texas produces the most wind energy of any US state.

good info                didnt know those facts    but the states must prepare better for the future
