Can you respond with respectful language?
Can you talk about something real that's not just a theory?
God said "Be fruitful and multiply."
He made this Earth, and it's capable of "sustaining" a lot more people.
You're just buying into the UN Agenda 21 mantra.
Oh, you are so confused. Science is established on facts. Scientific theory is a collection of facts.
Even so, global warming is a fact, not a theory. I will explain some of the basic science
1) It is a fact that the Earth is warmer than it would otherwise be if it had no atmosphere.
2) Greenhouse gasses like CO2 absorb electromagnetic radiation in the infrared band. This frequency band is the range of frequencies that we experience as radiant heat.
3) The chemistry of combustion requires that CO2 is produced when carbon based fuels are burned, a process also known as rapid oxidation. Oxygen combines with the carbon in the fuel to produce CO2.
4) The isotope of oxygen in fossil fuels is distinguishable from that of fuels such as wood by a process known as carbon dating.
5) In 1958, Keeling began recording the mixing ratio of atmospheric CO2. Since then, CO2 content has continued to increase. The magnitude of this long term trend is comparable to and exceeds that of the seasonal variability.
6) The global mean temperature of the Earth has been documented since people have been interested in weather which affects our daily lives and the agriculture that we depend on.
7) There are a handful of factors that affect the global mean air and sea surface temperature. These include orbital mechanics, heat exchange with the oceans, GHG content, solar energy (TSI), as well as aerosols from volcanic eruptions and man made pollution.
a) Orbital mechanics affect global temperatures on the scale of the ice ages and are the cause of periods of glaciation. Orbital mechanics is not the cause of global warming.
b) Volcanic eruptions and man made pollutants are short lived, with volcanic eruptions affecting temperatures over a few years. The affect of man made pollutants is well known and has declined as a result of environmental policies.
c) The IR absorptive processes of the GHGs are governed by quantum mechanics and is well understood.
d) The GHG of water vapor is directly proportional to temperature. The process of evaporation and precipitation follows the fundamental gas law of PV=nRT which we experience as weather. Water vapor is not an independent cause of GMT.
e) Methane content and changes is insufficient to cause AWG.
f) CO2 is the single demonstrated cause of the long term trend of global warming.
g) The affect of solar irradiance can also be shown by plotting temperature against TSI. TSI is proven as not the cause of the temperature variability.
h) Heat exchange with the oceans is also a well known cause of atmospheric temperature change. The cyclical ocean temperature events known as the Pacific Decadal Oscillation PDO, Atlantic Multi-Decadal Oscillation, El Nino and La Nina are well known. These cycles are apparent in the decadal long ups and downs of the global mean air and sea surface temperature record. The short of it is that when taken together, CO2 is the clear cause of the long term increase, PDO strongly affects the cyclical variations, and changes in TSI are insignificant.
8) There area couple of methods for connecting the various factors of any system.
The most definitive is to apply 400 years of hard mathematic scientific laws to show how the empirical measurements fit together to produce the affect of global warming. If you have a team of PhDs and a super-computer, this is the way to go.
Another method is basic statistical data analysis techniques. Specifically, a multi-variate regression is a realistic approach for most. Excel and Open Office have data analysis packages. There are websites that will do regression. There are a number of data analysis packages on the market, including the open source software R,
The results of of a multi variate regression is
Anom = -122.7+0.00944*CO2+0.0804*PDO+.08793*TSI
The likelihood of this result being random chance is 7.466e-15. This is a probability of 1 in 133,940,530,404,500. This is one in 134 trillion. In practical terms, this is a guarantee that these factors, CO2 and PDO, are drivers of the global mean air and sea surface temperature.
GMT can be estimated to a good degree of accuracy by plugging in the empirical data for the three factors. Monthly data is the most definitive though yearly averages work well enough. And this technique is obtainable for those of us who don't have a PhD in physics.
9) Correlation alone doesn't prove causality, correlation is required for causality and lack of correlation does prove no causality. Combined with the centuries of well established science, AGW is a fact from adding up thousands of smaller facts.
Causality requires correlation. The variable TSI is included for this reason. TSI is demonstrated as not being causal. It is in general, obviously. But, during this current period of global warming, any affects due to changes in solar irradiation is swamped by the affects of CO2 and ocean heat exchange. Again, in practical terms, this is a guarantee, of 134 trillion to one, that CO2 and PDO are drivers of the GMT.
While correlation alone doesn't prove causality, the combination of the known physical laws along with correlation does prove causality. The multivariate linear regression result is supported by the basic science.
The short of it is this, basic science make it clear that global warming is expected by an increase in CO2. And, empirical data makes it clear that CO2 is affecting the planet as expected. The empirical data also makes it clear that it isn't something else.
Global warming is a theory like rain comes from clouds is a theory. You are welcome to do the basic science yourself.
