Does human activity really effect climate change?

The mass panic over green house emissions must be put in perspective. Our atmosphere is made up of Nitrogen 78%, Oxygen 21%, Argon 0.93% and Carbon Dioxide poultry 0.036%.

Carbon Dioxide levels have risen by .0072% since 1900. The biggest producers of this gas are natural phenomena. Super volcanoes such as Toba, Yellowstone and Taupo are big offenders. Milos in Greece alone produces 2% of the earths CO2.

Water Vapour accounts for 96% of the greenhouse effect without which world temperatures of -18 degrees Celsius would be the norm.

There is evidence to support a medieval warm period. Between 1050 & 1400 the temperature was 0.75 degrees C hotter than it is now.

Factors such as our distance from the sun and the heat of the sun have far reaching effects on our climate.

Australia rates 19th out of 20 of the worlds worst emitters. The top 4 emitters account for 63.8159% our share a meagre 1.4971%. The top 4 worst have not signed the Kyoto Protocol. We are amongst the lowest of per capita emitters (17). Brazil, Indonesia and India are the worst culprits. This is due mainly to tree clearing.

According to Dr S Fred Singer former director of the US Satellite service “ There is no dispute at all about the fact that even if punctiliously observed, (the Kyoto Protocol) would have an imperceptible effect on future temperatures—one-twentieth of a degree by 2050.”

Climate change is inevitable. We have to manage the situation.

A massive storage reservoir exists. Lake Argyle formed where the Ord River enters the Carr-Boyd Ranges just south of Kununurra. Lake Argyle is now the largest fresh water storage in mainland Australia. Its storage capacity is 10,760 million cubic metres of water or about 9 times the water volume of Sydney Harbour. The overflow pours fresh water into the sea. In this state the Ord River is a massive source of water and could be piped to irrigate the whole of North West WA as well as Metropolitan Perth. Coupled with a rail line the whole of this huge state could become the granary of the world.

The layer of atmosphere that we live and breathe in is the smallest layer of the atmosphere. With the right wind pollution produced in China can be in America in a matter of days, and visa versa.

Human beings definitely have an effect.
For one thing, C02 increases the amount of water that air can hold.
C02 is heavier than air, so it weakens natural convection cycles which drive cooling in our layer of atmosphere. C02 production of humans is less than volcanoes, but is more continous, and has less chemicals that reabsorb the C02. In short, human pollution is worse than any form of natural pollution.

Deforestation complicates the problem as natural forests, reabsorb more overland C02 than almost anything.

Kyoto protocol was too weak to have strong effect on policies of government, consumers or industry. What is needed is some kind of massive public transportation system overhaul. No government is willing to fund that. Anything that requires the private individual to change by their own massive effort will also fail. So that leaves industry to make up for what government and individuals refuse to do. Industry won't change until it is profitable, however, and it may be very bad by then.

An unheard of solution, would be to have car exhaust filtered through lye and water vapor. This would remove C02 from the exhaust before it even reaches the atmosphere.

Of course it does! Automobile exhausts, smoking, industrial emissions are the major contributors to global warming and greenhouse gases. Who else but humans are responsible for it?
