Leading Climate Change Experts Blame Hollywood for Spreading False Fears

[Mark L. MN]

The one problem we humans have is that we have been on the scene a very short time. With a even shorter record of history. Granted we can to archeological 'estimisations' of the past. But that is all it is, a estimisation. To really look at what is happening now and what may be happen in the future we need to look at the over all history of the planet. Don't forget the planet used to be a lot hotter, not warmer, but hotter. Hot enough that there were no polar ice caps, glaciers or such. There has not been one ice age, but several. I don't know how many there have been. So we must ask a lot of questions before 'jumping' off to the wrong conclussion. Though I am very much for stopping the use of fossil fuels for powering our various activites. But again, ask the questions, consider all the possible out comes before acting. And maybe making the situation worse. A quick solution to a problem may bring a whole new, even worse problem latter.

Why?

That is why will billions die?

Global warming is true, there is little question about that. Whether it is caused by human activity is questionable. Human activity may be responsible for some or all of the observed warming. But even if humand activity is responsib;e for all the global warming that has occurred why will billions of people die?

where you quoting my post or asking question in regard to my post

also i dont get the end of your post but here is the my answer
why will billions of people die for a few simple reason, raise in temparature = more drought irrigation problem, heatwave, desertification, spreading of hotter zone disease(malaria for example).

desertification = less forest to absorbs and retain greenhouse gas so higher rate of warming
raise in temprature = destruction of most if not all of the sea ecosystem and also the release of methane held inside ice crust at the bottom of the ocean and inside the permafrost in the northern part of Russia and Canada, also melting of the ice cap of Greenland and Antartica why worry about those two and not Artica, well for one simple Artica for the most part is ice floating on water while the two other is ice and snow on land the ansuing raise in sea level would be catastrophic for place like Bengladesh, costal China, and India and closer to us places like Florida or Louisianna forcing the displacement of millions if not billions of people
heatwave = big time detrimental to human health after three days of daytime temperature over 36C and nighttime over 26c the amount of elderly people suffering from heatstroke rises by about 17% etc,etc...
as for this been fully our fault or not and as for this been natural or not the problem does not lie there but more in the what will happen then, whe have technology and all but currently none are evolved enough and neighter do whe have nor the capacity of making them happen in the timespent that whe have left and i insist on the meaning of "time left"
also another problem that was ignored for a long time was the effect of another problem that is not often talked about and this global dimming in the early 80's when talk of global warming and air pollution arose from the dark lots and lots of manufacturer started making anti particle system for cars and vehicule thus reducing the amount of airborn particule but not greenhouse gas this made some scientific realise that the greenhouse effect whas way higher then previously tought and why is that for one simple reason the millions of tons of particule that where previously clouding the earth traped inside the cloud where no longer helping in shading the earth surface by making cloud denser thus reducing the effect of greenhouse gaz so actualy this previous pollution was keeping the effect or more precisly the rapidity of the effect of greenhouse gases effect hidden.
anyway to learn abit more about global dimming the was a good documentary made by the BBC on it, get info on it @ http://www.bbc.co.uk/sn/tvradio/prog..._summary.shtml
or wikipedia as a good text on it @ http://en.wikipedia.org/wiki/Global_dimming

edit: just saw also that the personne who posted while i was writting this as a link in its post about global dimming

Ever heard of the Medieval Climate Optimum?

It was a boon to humans and most other life forms. Maybe it's not so bad.

What about shrinking ice caps on other planets? I don't think our carbon can get that far. Those who want political control over all economic activity keep ignoring the single biggest energy input to the entire system -- the sun. Look how much temperature change there is from night to day, and think about what a slight change in solar output would do.

Global warming takes place every morning, for half of the world.

Interestingly, all the evidence seems to show that the world is a better place to live when the temperature is warmer and carbon dioxide levels are higher. Unless you live in the desert, of course. And although there are a lot of attempts to show otherwise, it looks like the temperature tracks solar activity, and carbon dioxide gets released as temperatures rise.

Should we really hand them a whip and a gun and ask them to rule us?

i have heard of it and alot of study reference there self on some of the data known of that periode but there is a few thing that should be taken into account when comparing both, true there was a big raise in average of temprature but that raise was far from been as big as the current one whe are seeing, secondly human demography influence as around 1000ad the population of the Eastern Empire and Western Empire wich is a bit more then the current european territory had a population of around 60 000 000 people while current Europe as a population of around 800 000 000 or about 15x more people, thirdly the urban and industrial occupation of greenspace from our periode compared to that periode, the amout of air polution from that periode compared to our periode also it is worth noting that the end of the Medieval Climate Optimum coincide with the arrival of the bubonic plague wich wipped between 1/4 to a 1/3 of the population in Europe it took almost 200 years for the population to reach that level again.

here is a graph where you can clearly see that the hight in temprature of that periode is far from comparable to the current one and far from happening as fast

When I was a boy we all expected to die in a nuclear holocaust, then it was DDT and Strontium 90 in coffee, then another ice age, collision with an asteroid, super volcanoes, bird flu pandemic and now global warming.

Nought out of ten so far, don't think I'll worry

nuclear holocaust did not happen because no jerked pushed the button and that they both knew that none would win at this game

DDT is known to cause long term damage and as been ban in most part of the world aside from third world nation

Strontium 90 in coffee dont remember and will not comment on it

the ice age thing only got talked about for a short periode of time but never had any basis to hold on to since there is no drop in temprature

collision with asteroid is still one plausible scenario as there are thousand upon thousand of orbiting celestial corpse floating around and the only question with this is when...

super volcano again another plausible thing but its still limited by when it will happen and nobody knows when...

bird flu pandemic still plausible as far as i know

as for global warming there are more evidence showing that its happening then that its not

so in my book there is currently 4 thing that are manacing to humanity but two of them are not controlled in anyway by human activity

[Geof]

....so in my book there is currently 4 thing that are manacing to humanity but two of them are not controlled in anyway by human activity

Whether or not human activity has contributed to Global Warming the chance of controlling it is essentially zero. It might be possible to stop CO2 emissions, that is the easy part, just stop using fossil fuels. However, all the CO2 that is supposedly doing its thing is not going to disappear for a long time so Global Warming will continue and if sea levels are going to rise they will rise, etc, etc. And humanity in its collective wisdom has brought its entire technology based society to a halt because it does not want to release more CO2. How are you going to relocate millions of people away from threatened coastal communities without transport? How are you going to feed them if fossil fuels are no longer available for use in agriculture. Whoops, I am forgetting, a few posts up you predicted billions would die...I think I have just found your mechanism.

i dont see the point of your reply in regard to the 4 thing that i think are possible
as for relocating the millions of people i never said i had a solution and if you want my unfortunatly pessimistic point of view whe are facing a way bigger problem then simply moving some few millions of people away from the coast and yes i still think that billions may die over the course of the current century as for feeding starving nation aint that ironic, lets polute to feed millions displaced by the effect of polution

as for getting rid of the co2 there currently study been made into various system but one of the most looked upon would be the use of iron sulfate in sea water

I didn't die of AID's and the IRA bomb missed me by 5 minutes.

After over half a century living under the shadow of one disaster or another I have come to the conclusion that it's all nonsense.

A nice warm climate for my declining years sounds good, but I think it will start to cool down after 2010.

[alexccmeister]

Don't forget, trees do a good job of getting rid of CO2 as well. Human just need to manage our resources. At the moment, most business men that cut down trees don't even bother with replanting. Only some do and that is not enough. There are tree species that can grow very fast, we could use this type of trees to regenerate the forest.

Find new ways to produce energy. Human are brilliant and I am sure if governments get involved, scientists and climatologist can do a lot more.

but those are all irrelevant, a bomb is a localized event and as effect over a really short period of time, as for aids it only effect human itself not the river next door or the migration of some fish or the next year crop of corn.

[Robin Hewitt]

Seem relevant to me. More relevant than global warming, the sky falling, being invaded by blood sucking Martian vampires and all the other things that might sell a newspaper.
