Re: Global Warming - what's behind it?

'THE Arctic's Northwest Passage has opened up fully because of melting sea ice, clearing a long-sought but historically impassable route between Europe and Asia.

Sea ice has shrunk in the Arctic to its lowest level since satellite measurements began 30 years ago, the European Space Agency said, showing images of the now "fully navigable" route between the Atlantic and the Pacific.'

Re: Global Warming - what's behind it?

A proposed political solution to global warming: carbon tax within every nation. Sure it's idealistic, but it's a start...

Re: Global Warming - what's behind it?

Fine if would make a difference, but it won't. Petrol prices are the highest they've ever been, yet we're driving more. Electricity is more expensive, but we're still wasting the stuff (on internet forums... ). People will just pay more to keep the same lifestyle and I'll guarantee that less than a few percent of the money raised goes into any useful projects.

Now, I've been wondering for some time why so little has been done on a governmental level about reducing CO2 output. Sure, there's the usual hurting econmies, selfishness, short-sightedness arguments, but even so, it's a deafening silence from almost everywhere. Also, there's been a very marked increase in interest in the moon lately. And also things have gone very quiet lately on the fusion front. Conspiracy theory, I hear you mutter, but there's a good reason.
Nuclear fusion has potentially the power to make us damn' near carbon neutral within a short time of starting up full scale. The most recent estimates were 50 years until that happens, but cogs appear to be turning in terms of moon shots and planning for lunar bases. The moon is one of the most abundant sources of tritium, which is an essential fuel for nuclear fusion reactors. If governements really had fifty years, why are they getting all geared up for moon bases so soon? I wonder if fusion might be making an appearence sooner than we think...

Assuming this doesn't happen:

Estimates are that we have less than 8 years to lower our emissions dramatically, not 50.

Only god knows how our world will look like in 2050 if we're going about our daily lifes like we did in the past.

If we mess this up we will trigger a few "tipping points" like the melting of the entire arctic ice shelf or the release of the methane gas stored in the syberian perma-frost.

I think only few people realize that this isn't just about politics, but it is a threat which is likely to outstrip the cold war in it's severity.

Depends on whose research you're following. A lot of reports reckon we've time, others say we're already too late. Mostly, they seem to be working on 20-40 years to reduce emissions to c.1990 levels. It'll still warm up a bit, but nothing too catastrophic, but then it does depend on who you're talking to.

Re: Global Warming - what's behind it?

Here's something you might want to read.

Ignore the title, just read the article.

I'm not saying that it will happen but it just shows you what "an increase of 3 degrees" really means.

Similar to the UK Liberal Democrat's recent proposal. They have the advantage, in being radical, in that they don't reasonably expect to be elected.

If economics was realistic - perhaps even scientific - all models would account for the fact that all resources are finite, and the basis of an economy is energy, not money.

Re: Global Warming - what's behind it?

The European Union's goal of keeping the global temperature rise to 2C is unlikely to be met, a leading climate researcher has warned.

http://newsvote.bbc.co.uk/2/hi/scien...re/7000449.stm

========================================

Most importantly, 3C may be the "tipping point" where global warming could run out of control, leaving us powerless to intervene as planetary temperatures soar. The centre of this predicted disaster is the Amazon, where the tropical rainforest, which today extends over millions of square kilometres, would burn down in a firestorm of epic proportions.

Re: Global Warming - what's behind it?

The arctic ice shelf has shrunken to a new record low, with scientists now predicting a complete vanishing of the ice shelf during summer in 2040 compared to their previous estimates which were around 2050.

Others go further and say we will reach that point by 2027 already.

I didn't realize that science had somehow become a belief. Like belieiving in religion, or in the supernatural, or in reincarnation. I find it mindboggling that even when faced with mounds of scientific data, people can still hold onto their "scientific beliefs" which, btw, beliefs can't be argued with.
My particular favourite is the Flat Earth Society ... some people seem to possess the fascinating ability to always find "scientific evidence" for anything they want to argue for

I'd forgotten about them, love this quote

Quote:
Once again, picture in your mind a round world. Now imagine that there are two people on this world, one at each pole. For the person at the top of the world, (the North Pole), gravity is pulling him down, towards the South Pole. But for the person at the South Pole, shouldn't gravity pull him down as well? What keeps our person at the South Pole from falling completely off the face of the "globe"?
They then seem to go on to argue, that even if gravity came from the centre of the earth, people from opposite sides of the globe would have a different idea of up, and would therefore float up off the face of the earth should they travel too far round.

Comedy! I do love those alternative theories at times... Wasn't there one lot who are convinced that the Earth is hollow with dirty great big holes at the poles so the aliens can fly in and out (as they live inside the Earth) and that all photos of the ice caps are in fact made up by the US Government to cover up the fact that they know the aliens are in there and that they are in contact with them?

Re: Global Warming - what's behind it?

A slight case for optimism, perhaps?

The European Union's goal of keeping the global temperature rise to 2C is unlikely to be met, a leading climate researcher has warned.
The leading climate researcher is, according to the link to the BBC story, Professor Martin Parry, who

Quote:
told BBC News that millions, if not tens of millions, would be at increased risk to their lives from a rise above 2C (3.6F).Professor Parry co-chairs the impacts working group of the Intergovernmental Panel on Climate Change (IPCC).
The "optimism" comes from my guess that, bearing in mind his position in IPCC and the timing of AR4 (the last IPCC report in Q1 this year), his comments probably don't take into account remarks by James Hansen in this paper (PDF alert). There is a more browser-friendly summary at The Oil Drum. The favourite quote from the Hansen paper:

Quote:
Despite the obvious relevance of “peak oil” to future climate change, it has received little attention in projections of future climate change. For instance, in the CO2 emissions scenarios outlined in the Special Report on Emissions Scenarios (SRES) of the Intergovernmental Panel on Climate Change (IPCC, 2000), socioeconomic and technological changes are employed as determinants of future energy use, without explicitly addressing the consequences of peak production of fossil fuels.
So long as we don't turn to coal burning to fill the energy gap - rather than promoting efficiency and non-profligacy - Peak Oil will force the rate of emisisons growth down simply by their being less of it around. Something I imagine will be a sight easier in mainland Europe than Britain and North America.

Re: Global Warming - what's behind it?

I'm sorry, but I've seen countless speeches and interview of James Hansen and he never seemed to proclaim that we can lay back and wait until the problem solves itself.

To the contrary:

Hi xapadoo,

I'm sorry if I gave the impression I was advocating complacency, or, indeed, that JH was. My idea was that IPCC forecasts overestimate remaining oil reserves and so their likely production levels. Thus the IPCC BAU estimates are, for once, overly pessimistic (assuming that increases in coal burning are not met with Carbon Capture and Sequestration [CCS]).

So the cause for "slight optimism" is that there might be more time before we hit a +2C increase.

Re: Global Warming - what's behind it?

no need to look for possible explanations for global warming any further:

http://www.venganza.org/:

You may be interested to know that global warming, earthquakes, hurricanes, and other natural disasters are a direct effect of the shrinking numbers of Pirates since the 1800s. For your interest, I have included a graph of the approximate number of pirates versus the average global temperature over the last 200 years. As you can see, there is a statistically significant inverse relationship between pirates and global temperature.


and they have damned strong arguments for the Creation of the Earth by Him too!
