It said "No replies to this topic" up over the post...so I wrote this.

<span style="font-family:'comic sans ms', cursive;"><span style="font-size:18px;">I don't think it's a scam, it's real and we are a contributor, but I'm still for fossil fuels and natural gas, and nuclear energy, and wind and solar-anything that works, done in a responsible manner.

I also think our world is warming and that we, as a species, are responsible for at least part of it.


*


But, I don't think this issue should be as contentious as it is seems to be.*


*


As time goes by and as technology evolves, the return on investment in greener technologies is, on average, getting shorter and shorter while the efficiencies of such technologies is, also on average, getting higher and higher.


*


And,*I think at some point it will inevitably be in everyone's economic interest to...well...go green.

Quit farting and belching if you are that concerned with global warming.

ice core studies do not show that carbon dioxide cause global warming, the opposite. every increase in co2 measured in ice cores happens hundreds of years after a temperature increase, not before.

<blockquote class="ipsBlockquote">Earth’s climate has varied widely over its history, from ice ages characterised by large ice sheets covering many land areas, to warm periods with no ice at the poles. Several factors have affected past climate change, including solar variability, volcanic activity and changes in the composition of the atmosphere. Data from Antarctic ice cores reveals an interesting story for the past 400,000 years. During this period, CO2 and temperatures are closely correlated, which means they rise and fall together.

<blockquote class="ipsBlockquote">This statement does not tell the whole story. The initial changes in temperature during this period are explained by changes in the Earth’s orbit around the sun, which affects the amount of seasonal sunlight reaching the Earth’s surface. In the case of warming, the lag between temperature and CO2 is explained as follows: as ocean temperatures rise, oceans release CO2 into the atmosphere. In turn, this release amplifies the warming trend, leading to yet more CO2 being released. In other words, increasing CO2 levels become both the cause and effect of further warming. This positive feedback is necessary to trigger the shifts between glacials and interglacials as the effect of orbital changes is too weak to cause such variation. Additional positive feedbacks which play an important role in this process include other greenhouse gases, and changes in ice sheet cover and vegetation patterns.

A 2012 study by Shakun et al. looked at temperature changes 20,000 years ago (the last glacial-interglacial transition) from around the world and added more detail to our understanding of the CO2-temperature change relationship. They found that:
<ul>[*]The Earth's orbital cycles trigger the initial warming (starting approximately 19,000 years ago), which is first reflected in the the Arctic.[*]This Arctic warming caused large amounts of ice to melt, causing large amounts of fresh water to flood into the oceans.[*]This influx of fresh water then disrupted the Atlantic Ocean circulation, in turn causing a seesawing of heat between the hemispheres. The Southern Hemisphere and its oceans warmed first, starting about 18,000 years ago.[*]The warming Southern Ocean then released CO2 into the atmosphere starting around 17,500 years ago, which in turn caused the entire planet to warm via the increased greenhouse effect.[/list]
Overall, about 90% of the global warming occurred after the CO2 increase (Figure 2).

Another possibility, methane through natural processes "decays" into CO2 and water vapor through interactions with singlet oxygen.*

A major culprit in atmospheric warming may be methane.
