It seems GWB has given green signal to US Air Force to develop space weapons. Is it really true and is it going to trigger an arms race. What are the other countries doing? I don't think UN would be of much help! :smile:

There is controversy about how certain the scientific community is of its conclusions about global warming: whether humans are influencing the climate and whether global temperatures will continue to rise rapidly in this century. There are two reviews that can be used as a reference for...

I have a question about nukes. If all the nukes in the entire world were detonated at once and dispersed for maximum kill, we're talking China, Russia, Pakistan, USA, etc... evertthing Could we kill all the human civilazition, or if not, what percentage could we kill? I'm having a...

This number came up regarding the Permian mass extinction http://www.bbc.co.uk/science/horizon/2002/da yearthdied.shtml I never realized that the threshold was so low. http://www.solcomhouse.com/metnoaa.htm This also ignores any potential tipping points which could come much sooner.

hey guys...Can someone help me out here...i'm trying to understand what the difference between a global maximum and a local maximum is? arn't they the same??

I know this may sound extremely silly... but, all ice at the north pole is floating... creating mass that would make the ocean higher than it would be... would that ice not be there, when ice melts it takes up less volume than when it is frozen? How would the north and south poles melting raise...

hi. I've got another problem. i have the function : f(x,y) = x^2 + y^2 +(xy)^-1 iam supposed to use the "extremalvalue theorem" to show that this function have a global minimum on the area x>= 0.1 ,y>= 0.1 and i also need to argue if the same thing is satisfied for x>0 and y>0. for...

I doubt it, can anybody back up their opinions with credible sources and/or reason's why they think global warming is, or isn't human caused? I am interested in your opinions, that's why I am posting this topic. Edit: 78 members and 558 guests and 213 spiders (whatever the hell those are)...

Which of the following countries is not one of the major exporters of food? 1. Japan 2. USA 3. Australia 4. Argentina 5. Canada I read somewhere that the U.S. was the second largest exporter and Canada followed as the third largest one. I also think that Argentina is a top exporter...

Hi, Hers's my simple idea about global warming. The suns energy is absorbed by the earth. The Earth re-emits this energy as heat. Human technology emits greenhouse gasses and produces more heat. Green house gasses are increasing in the atmosphere. The more CO2 and other...

I'm supposed to find the absolute max and min for f(x,y)=sin(x) +cos(y) on the rectangle defined by 0<=x<=2*pi 0<=y<=2*pi. Can someone point me in the right direction. I got the critical points but i don't know what to do after that.

I came across information, such as data published by The Pew Global Attitudes Project, however there didn't seem to be much statistics available (yet) on what is important to people around the world at this time. I thought it might be interesting to see what is important in different countries...

Crackpot or exiciting paradigm shift coming up? http://arxiv.org/ftp/physics/papers/0502/0502135.pdf This guy has probably read my https://www.physicsforums.com/showthread.php?t=2974 but there is much more. Discussion?

At the latitudes of the UK and Northern Europe we would expect a climate similar to that of Alaska or central Canada. Thanks entirely to the gulf stream, which bathes our shores with water carrying the heat equivalent of one million power stations, we currently have a much warmer climate. The...

Clauset and Young, in their new paper http://www.arxiv.org/PS_cache/physics/pdf/0502/0502014.pdf , apply standard modern statistics to a database of terrorist strikes ordered by the number of people killed or injured. They find that extreme cases, such as 9/11, are not outliers, but find their...

"Unexplaining" global warming Realclimate is an initiative of concerned climatologists who may seem to fear that the global warming message is waning. I tested the objectivity of the place by applying the next comment: Obviously, the comment was not honored. Anyway, to anybody...

Article in the Daily Express by David Bellamy OBE Feb 3 2005. I first heard about global warming in the eighties and right from the start i didn't believe in it. I teach botany. i have researched and taught plant anatomy, ecological physiology and the history of vegetation at universities...

This makes for some interesting reading. http://www.foia.cia.gov/2020/2020.pdf The rise in economic power of China and India is pretty much a given. One prediction is really striking. They predict the world's economy to grow by 80 percent over 2000 levels. At that rate, the worst that...

Suppose I am a defense attorney--I am NOT--arguing for an underdeveloped old-growth tropical rain forest and a coral reef from tumultuous destruction by development. If I could only save ONE, it would be the coral reef. (My instructor said something along the lines of: "The destruction of our...

I read somewhere that one of the dangerous consequences of global warming is another ice age, kinda like what we saw in the movie "The day after tomorrow" . My friend was arguing with somebody about whether global warming will cause a drop in temperature or instead rising temperatures. When I...

The global warming bane for flooded civilization, geology and ecosystems at low altitudes can be a bonus for glaciologists "while they last" in higher latitudes. Would you like to predict what treasures the thawing climate will reveal in the world's remaining glaciers?

The Global Positioning System is nowadays considered as the prime example for the everyday importance of Relativity. It is claimed that without the relativistic corrections (which amount to 38 microseconds/day) the error in the determination of the position would accumulate quickly to values...

Is this fair? Full Story I know this forum is full of arguments over whether or not global warming is even taking place, but even if it can be proven that it is, and that it is largely caused by greenhouse gases, is it fair to sue a nation for that? What is the U.S. doing that 90% of...

Children of Millennium has posted a rather impressive-looking global map of national IQs. Here is the map: http://www.childrenofmillennium.org/eugenics/pages/articles/IQmap.gif It is linked from this article on national IQs: http://www.childrenofmillennium.org/science.htm

Since there seems to be a lot of controversy about this, I thought I'd do a little poll to collect the oppinions of you guys. Is global warming a real threat caused by us, a purely natural occurence or a cross between misleading figures and political spin? Views & opinions appreciated.

I have been trying to find a summary of global ethnicity and percent of... the origin of the bug in my hat is the current American political statements of 'minority' 'majority' and the misnomer seems obvious that northern European are a minority yet hold the power echelons and thereby decree...

Just a question I am a little stuck on. I missed last week's chem lecture: What effect would each of these changes have on global warming? a) volcanic eruptions b) CFCs in the troposphere c) CFCs in the stratosphere Here's what I think so far.. a) Volcanic eruption release large...

is global warming a natural phenomenon? I think it is . But we can enhanced it such as we produce tonnes of carbon dioxide every day, causing the greehouse effect strengthen and finally lead to global warming .

As I see a new brave offensive against those devious satanic gasses and obviously, weather of mass destruction is about to destroy the world. So, perhaps it's time to review the science behind greenhouse warming. How about using the scientific method this time. It seems to be getting...

We already had some brief discussion (2 posts) of this paper in the "Intuitive...Program" thread that is serving as a catch-basket for Loop-and-allied Quantum Gravity links. It probably could use its own thread, to allow space for more discussion, if desired. After I posted this mention of the...

I'm not surprised, Space daily I think we are heading for a rigourous paradigm shift.

In a low key admission, Bush officials are allowing that they were wrong in their summary dismissal of man induced atmospheric warming. link:www.nytimes.com/2002/06/03/science/03CLIM.html

With all the talk of wind, solar power, the hydrogen economy, nuclear power and efficiency as ways of averting global warming, depletion of resources, has anyone contemplated simply reducing the amount of humans? Say, down to half a billlion? Ditch the baby bonus', link aid to third world...

Global warming on retreat. The British press is usually in the top scaremongers when it’s about the potential disasters of Anthropogenic Global Warming. It’s about finished by now. See how elegant the retreat is: http://news.telegraph.co.uk/news/main.jhtml?xml=/news/2004/07/18/wsun18.xml

Im, sure global warming has been debated many times, but have we learnt anything from all the data recordings taken all over the world, surly they would show a weather, "trend", in the UK we have had local record breaking weather conditions, rain fall, temperature and wind speed. .But...

Every time I read about global warming (cooling) and climate change, I have a tendency to think: this is such a longterm problem, with very few consequences for our lives; it should be of no concern to us. The other day I read that Greenland's entire icecap could melt by the year 2350 (oh...

"No doubt": Human Activity Affecting Global Climate Change An interesting link that I had tucked away. http://globalchange.gov/ Here is one story from the link. http://globalchange.gov/

Hello Everyone, If global warming wasn't enough, we now have "global dimming" to add to the equation. Although i get a funky feeling in the pit of my stomach both global warming and global dimming are inter-connected. Here's a...

Is there any practice, belief, value, etc ... in human history (recorded that is) that has remained constant throughout the ages? Is there nothing we can agree on? If no, then does it mean that no matter what we agree in the future - there can never be a claim of total universality (of the...

Hello All, I've always been curious about historical seismic activity prior to the 20th century. Then the advent of the last century until now, i have heard that seismic activity has increased dramatically. Then i got to conceptualizing how many underground nuclear test's have been...

I'm a physicist, and a skeptic. I have been all my life. Now, when it comes to global warming, I admit to not knowing a great deal. It seems that many in Academia feel that this is a legitimate threat. However, I have this growing suspicion about the integrity of many of these academics in...
