Environment - November 2007

The proponents of manmade global warming have consistently stated it's because of greenhouse gases.

To counter this claim skeptics have provided alternative explanations but they're forever changing. Recent explanations have included cosmic rays, the oceans, increased solar output, Pacific decadal oscillation, blackbody radiation etc. Could someone please let me know what the current explanation favoured by the skeptics is?

Each of the many explanations is, in it's own right, claimed to account for the recent warming and thus prove human activity isn't responsible. Assuming the skeptics are correct and they're not just coming up with anything that might sound plausible, shouldn't the planet be warming many times faster than it is?

When the Vikings farmed on Greenland the only part of the country they could inhabit was the southwestern extremity as the rest was ice. Today, they could have landed anywhere as almost the entire coastal region is ice-free, up to 200km (120 miles) wide in some places.

What I'm wanting to know is how much more land is available now as a consequence of global warming? Ideally compared to when the Vikings landed there 1000 years ago or when temperatures peaked during the 'Medieval Warm Period'.

To avoid any confusion - Greenland was so named to attract settlers, it never was a green land. The story of how Greenland was settled and the propoganda behind the name can be read in the biography of the first person to settle there - Eric the Red.

There have been times in the past when the planet has warmed up and cooled down. How does the rate of historical warming and cooling compare to the current rate by which temperatures are changing?

Please feel free to use any global temperature record you like and compare the current warming/cooling to whatever time in history you like.

When lead was used, scientist said it was safe. But now they say it's dangerous. Once the 1900s scientist said that global warming was rubbish but now the whole world has joined together, SO WHATS YOUR OPINION

Greenhouse gasses are only one element in the many factors that control our climate.

The main greenhouse gas is water vapour, accounting for about 95% of it.

The total CO2 accounts for only about 3% of the greenhouse effect.

The vast majority of the CO2 entering our atmosphere is caused by evaporation from the ocean, after that there is respiration, decomposition and volcanic eruptions. The total caused by human activity is only a minute fraction of the total CO2 entering our atmosphere.

So in short

Greenhouse gasses are only one part of the story

C02 is only a minor greenhouse gas

Human contribution to C02 is only fractional.

So how can man made CO2 be the main driving factor in our climate? Or if you believe the alarmists, it is the only factor.

Because we've got fluorescent lights and many people are buying them and they work. The one outside is crazy bright. Maybe cities and towns should start having them. I'm just considering this now.

Any intelligent person knows that volcanoes create large amounts of CO2.
So why should we trust Co2 readings from "largest active volcano on Earth" according to:
http://volcanoes.usgs.gov/Products/SProdsRegions.html

The Alarmists seem to trust these CO2 readings and this is their primary source of CO2 data. Maybe they ARE NOT Intelligent???

I would like to see arguments regarding how much of the warming over the past 100, 50, and/or 30 years has been caused by humans, and how much has been caused by other factors.

Please provide evidence to support your argument. Answers which do not provide supporting evidence will not be answering my question, and thus will be violating the community guidelines and will be reported.

Someone recently brought arsenic into the debate, so I want to expand on that. Hopefully I will not be reported for a violation, again. I know I run the risk, since I am challenging the dogma.

Here is my premise. Isn't it true that if we drink water with tiny amounts of arsenic in it, the arsenic will gradually build up in our system and we will die? The arsenic is a poison to our system. Lets assume I purposefully drop small amounts into someone's morning coffee, every day. If they die in a month of arsenic poison, the police would charge me with murder.

How does this compare to global warming? Well, the AGW crowd tells us that human use of fossil fuels creates vast quantities of CO2 that is the primary cause of global warming. Further we are supposed to believe that global warming is bad now and accelerating at an alarming pace. Eventually, the earth will be uninhabitable. In effect, burning fossil fuels is killing future generations.

What I feel is it is very costly for a poor country like India to spend thousands of crores in US wanted nuclear deal. It would be better if the same is invested in safe and perennial resources tapping, like wind, solar and hydro energies.

to conserve by increasing employee telecommuting.? Isn't it a scandal that this Pres can't bring himself to do the right thing and put OPEC on notice. If Carter were President he would be on it immediately rather than coast to the end of their term. I guess invading Iran or Venezuela makes better sense?
BTW, it would also lower CO2 emissions and begin working to reverse GW. Lower particulate pollution too. I guess it only makes sense to little naive me and none to all the politicians who need campaign contributions from the fat and happy oil industry.
