Global warming, human or not?

[tropicality]

Having broken out of the 'being controlled by the media' lifestyle and becoming aware of everything going on around, I've always thought to myself that the 'global warming' issue is just a natural earth cycle.

I then came across this video: What we are not being told about the climate - Google Video

And while doing a research assignment for college I came across: David Suzuki News*November 10, 2006:*Stern warning changes the climate debate

Now I agree that it is a good thing to reduce emissions for our HEALTH... Is the whole global warming issue just that? To reduce emissions to better our health, while providing more reasons to tax the citizens, and promote new industries? (By making it cheaper to just use more efficient technology than to use pollution creating technology and be overly taxed for it?) And the earth is getting warm from a natural cycle that will pass like it has in the past?

Personally, that is my view. But I thought I'd put it out here for other 'concious' people to examine.

What do you think?

(I figured this would be the right place to post this, because the greatest effect emissions has is on our health)

I haven't been able to understand why global warming, due to human causes, is still being questioned.

Most scientists agree that global warming is due to human causes. I would also add that whether you indifferent towards, love, or hate Al Gore, An Inconvenient Truth (his documentary on global warming) is excellent.

Here's one stat that stands out to me:
Of 928 articles dealing with climate change in scientific journals in the past 10years, 0% had any doubt as to the cause of global warming.

Of 636 articles in the press about climate change over the past 10 years, 53% cast doubt.

I'll go with the scientific journals because that's where the studies are published, and it supports what I have read myself. I have seen web sites that try to argue global warming is not caused by humans, but I haven't been able to find many that use credible sources that either rely on studies funded by oil and energy companies or have a mission to promote a "conservative" agenda.

Just wanted to add one thing about that video. It was produced in cooperation with Friends of Science. Friends of Science is really a cover for the oil industry according to sourcewatch. So don't take too much info from there.

YES! It's working! I intended warmer global weather so I wouldn't have to travel so far for vacation.

Hooray intention-manifestation!

[Shaden]

TechnoGuyRob, you should be careful what you wish for

What I don't understand is how the government make all doom and gloom about the situation of global warming and then go ahead and do absolutely nothing about it. That confuses me - and proves we have incompetent world leaders. Oh my what a surprise...

My own view (short version) is that global warming is a natural Earth cycle - and would happen in any case, but that we are accelerating things by our actions. Instead of happening at some distant point in the future, it's happening now.

As for 'careful what you wish for', it's forecast for 38C (100F) here tomorrow, and it isn't even summer yet. There's also talk of snow arriving here in the next few weeks, and it hasn't snowed here for about 170 years. Extremely unusual weather.

I don't think they're incompetent, I think it's a matter of time scales. Political careers are measured in years, climate change is measured in decades.

It would take a brave politician to say "This will be a huge problem in 30-50 years, so we're going to raise your taxes and start dealing with it". It absolutely needs to be done, but any politician who does it risks being voted out, because the voters' concerns tend to be more immediate.

Politicians realise that there's political points in making noise about climate change, but that to actually do something about it would require unpopular changes (eg. look how much people whinge when petrol goes up 20c - can you imagine the career of a politician who taxed it?). So they just make the noise.

Politicians will fix the environment if they can do it without disrupting the economy. But they can't, because the economy is unsustainable ; it draws too heavily on finite, damaging resources.

The problem can't be fixed at the level at which it was created, but people are still thinking at that level.

[TheColonel]

Yes, but there are other much greater forces contributing. Our poles have begun to shift, and our planet is going through growing pains. This is a natural (and overdue) occurence.

This relatively fast magnetic decay - it must weaken substantially before a full polarity reversal - will take perhaps a few hundred more years. And during that time, we are less protected from solar radiation. And you can guess what that means.

This phenomenon is real, and although it is largely ignored in the press, is a huge contributing factor to all kinds of planetary changes. Us humans? Yeah, we aren't helping global warming much. But if polarity shift is an elephant, we're a gnat on the elephant's @ss.

Whats your source?
Preferable one which numbers on how much this phenomenon does? Every scientist that I heard of that work in that field thinks that this phenomenon isn't fast enough to have effects in our lifetime.

We (Melbourne) had a 36C (97F) degree day in September - start of Spring. Last week we had a 13C (55F) degree day and yesterday it was 36C (97F). Melbourne is not known for its consistent weather, but this is a bit ridiculous.

Last year I was living in Margaret River, WA, and they had the coldest summer in living memory. I went on an indigenous tour in Autumn and the Aboriginal guide was showing a heap of spring time plants that were still out.

Last year on the other side of the country Melbourne had one of the hottest summers on record.

What I've read suggests that some the change is due to natural cycles in the weather (and we've just come out of an unusually consistent period), but I don't think it can be denied the effect humans are also having.

I take a 2.5 (250km) hour train trip to my parents place through country side almost devoid of trees that 200 years ago would have been 250km of forest. Every morning I ingest lung fulls of exhaust as I ride to work. Some days I can look out the windows and the distant buildings are veiled in smog (not often luckily). I've lived in a country where I could count the number of days you could see the horizon through smoke on one hand.

In Australia, with such a low population density, a lot of the pollution is hidden from us - big pollution industry is located in remote places.

I find it astonishing to hear that some people can't see that our actions would / could effect the planet.

Except that we're adding inputs over and above the natural cycle, risking pushing the system into a state of runaway* positive feedback from which it will not recover for hundreds of thousands of years.

TheColonel, you are aware that hundreds of years is a long time compared to the timescale for predicted significant effects of human-induced climate change, aren't you. And that the current decline may not be presaging a reversal at all.

The present strong deterioration corresponds to a 10-15% decline over the last 150 years and has accelerated in the past several years; however, geomagnetic intensity has declined almost continuously from a maximum 35% above the modern value achieved approximately 2000 years ago. The rate of decrease and the current strength are within the normal range of variation, as shown by the record of past magnetic fields recorded in rocks.

One should note that no one knows if field decay will continue in the future.
...
Some speculate that a greatly diminished magnetic field during a reversal period will expose the surface of the earth to a substantial and potentially damaging increase in cosmic radiation. However, Homo erectus and their ancestors certainly survived many previous reversals. There is no uncontested evidence that a magnetic field reversal has ever caused any biological extinctions. A possible explanation is that the solar wind may induce a sufficient magnetic field in the Earth's ionosphere to shield energetic particles even in the absence of the Earth's normal magnetic field

From here



*Yes, I know that positive feedback = runaway

[songwriter]

It is not clear if it caused by the Earth itself or by human activity. Possibly the two things are causes but we don't know which one is the major cause.

Anyway, this is going faster that no-one imagined... !.

In Spain we use to have cold weather from October on. And now we go to the streets with just one shirt. Sometimes I have to look twice at the calendar "November 24th" ?. I feel like if someone is joking on me or us.

We use to have December and January as our most cold months.
There's only 7 days left to December, and the sun is shining... I don't understand a thing.

[fourthdan]

You know the wierdest part? I live in a desert out here in the middle east and every year it gets colder and colder

not that i mind... could be because the local municpalities are planting more and more trees? But i have a gut feel it's gotta do with the shift in the global weather patterns...

[Serafin]

Here in Switzerland the glaciers are melting quickly and the permafrost in the alps is no longer a trustful solid ground for buildings. Just to protect our roads from falling rocks due to the higher temperature in our country costs billions of dollars!

I think there should also be another reason to reduce our oil consumption. Simply because fossil fuels are limited resources. And I don't think it's right to burn all the oil or coal in just three or four generations. Maybe our next generations would have a much better use for the oil than just to put it into a tank.

Unfortunately people only change their habits if they have to pay much more for the same. This is the negative side and it takes some time to find a new balance. On the other hand, higher costs for fossil products opens a wide field for complete new solutions. A lot of smart companies in Europe and Far East have already started to develop new energy saving products and thereby created many new jobs. And this business is growing rapidly!
And everybody who wants to participate has already to be quick to catch the rolling train!
I'd like to ask you guys from the US: Are you (and your government) fully aware of this new global trend? Is this an issue, the positive effects on the economy and not only the short-term costs?

Nova.

You don't expect me to actually read the research, now do you?

[KevinG]

1. Show me proof that global warming exists and that we are not simply viewing normal climate shifts up AND down of the Earth.

2. Show me proof that "global warming" is man-made.

3. Tell me why temperatures on Mars are rising, yet there are no SUV's or CFC's there.

4. Tell me exactly how much temperatures have increased in the last 100 years.

Tell me those things if you're a supporter of the global warming religion and then we can talk about why I believe global warming is a liberal attack on capitalism.

[Trina]

I think it is very arrogant of humans to assume that they are so powerful they could change the earth all by themselves, and very naive of humans to think we have absolutely no effect on the earth at all.

[stephencp]

Assuming that it's happening, I"m not sure that I'd leave it up to the government to try to stop it, or handle it's effects. Check out the below links for the libertarian perspective (on how to handle the consequences, not deny that it's happening)

Yes....I'm in Ballarat (Vic) and a Wednesday about a fortnight ago it snowed...heavily. Then on the Friday...it was 36 degrees! It was such a rapid change in temparature.

Just last week, we had very very strong winds...I lost my garden shed and some people lost there roofs as well as 8 out of 10 trees losing a branch or two. I've been here ten years and never seen weather like it. Lake Wendouree in Ballarat is just a few puddles here and there and many dams and other lakes round the place have dried up completely.

The earth may have a natural cycle of warming up and cooling down...but to show signs of such a rapid change is scary and not natural.

Yes, those stats came from the documentary. While the documentary isn't the most exciting film to watch, I do think it's educational and important. One of best things Al Gore does in this is address what the skeptics say, and point out why they are wrong, backed up with data. Meanwhile, I still can't find a study that doubts humans are the cause that isn't based on funding by oil and energy companies or a group pushing so-called conservative interests as their agenda. I'm no scientist, so I have to trust the experts here; to me, that means I believe humans are a significant cause of global warming.

The point is, whether or not anyone believes humans are the cause or not, if it continues as it is, we're going to have some major problems. Maybe we won't see the worst effects in our lifetimes, but that doesn't mean we don't have a responsibility to do something for future generations. And I would rather it be that humans are the cause; at least then we have some control over the matter and we can do something about it.

There are a number of things we could easily do:
- We could start by raising vehicle fuel standards in the US to something more in line with what other developed countries have (ours are very low).
- My office and my school's labs leave their computers on all night. Why?
- Replace light bulbs with compact fluorescent light bulbs. They cost a little more, but are much more efficient and last years longer.
- As needed, replace appliances with more energy-efficient models.

It's not too difficult for one person to do their part, and if enough do their part, it'll make a major impact.

My view is that we are wittnessing the rebirth of paradise. The old earth, and old world mentality, and interrpretation of events is passing away.

Quite naturally, those of the old world, and old world mentality will be fearful.
The new earth is unfolding before our very eyes. Those of this new world, and mentality are joyful, as their deliverance is near.

The meek shall inheret the earth.

Seeing is believing, but if i went on that basis Santa Clause exists, as I have seen him before, as does the easter bunny, but I've never seen president Bush or Tony Blair, maybe their fictional too???
