Change in Climate

 This is a science report.

Nuclear explosion not only will cause the radiation damage and death of many people, it will also change the climate dramatically in the area where it happened.And if the nuclear war will start, it will change the climate of the whole world. This possibility, proposed in a paper published by an international group of scientists in December 1983, has come to be known as the “nuclear winter” theory. According to these scientists, the explosion of not even one-half of the combined number of warheads in the United States and Russia would throw enormous quantities of dust and smoke into the atmosphere. The amount could be sufficient to block off sunlight for several months, particularly in the northern hemisphere, destroying plant life and creating a subfreezing climate until the dust dispersed. The ozone layer might also be affected, permitting further damage as a result of the sun’s ultraviolet radiation. Were the results sufficiently prolonged, they could spell the virtual end of human civilization.

I wonder than the country we live, the envoriment, the climate effects our eye colour, hair colour, weight, tall?What do you think, for example someone went a country, does his generation has different phsical features?
Brailleonsundays, thanks, I know that bu I asked a different thing.If you go different country, has your generation got different features?

I am doing a research project on Supervolcanoes and their climate effects. If I were to (hypethetically) say that The supervolcano under Yellowstone National Park were to erupt, I know that the surfuric acid cloud would kill everything within between 250-700miles, create a nuclear winter, result in lower temperatures by 10-15C, and destroy our ecosystems.

How long would it take before the ecosystems were able to recovery, and how long would (the remainder) of humans be forced to survive with limited vegetation? And how long would the nuclear winter last? (I have heard people state between 4-5years, up to 10-12 years?)

Thanks for any possible assistance.

How about a Energy Star HDTV vs. A regular HDTV?

What will the effects of climate change be in the upcoming years?
Will there be new contributors?
How do we help stop it?

I am organising a short conference on climate change and energy at work. How best do I ignite people’s interest? Can you think of any interactive elements that I can use? Any ideas (however wild) are welcome.

I also want to minimise the carbon footprint of the event. Can you recommend any caterers that offset their energy expenditure?
Reply to D S – Yes I am a cult leader, but only in my spare time. This conference is being organised in my other capacity as a bureaucrat.

I’m pricing french doors and yesterday, at Home Depot, the ones I like have the Energy Star approval, but it costs a lot more for the Low-E glass. The sales person said the Low-E probably wouldn’t make a big difference.

What do you think the two most significant contributions that mankind is making to climate change and why?

I just moved to an apt and installed is an energy star room A/C unit. It gives two options for cooling: Cool and Energy Saver. I figured the energy saver would save me $$ but im worried bec it kicks off when the room gets cool then kicks back on a few mins later. Wont that constant on-off actually cost me more? Should I just leave it on Cool at all times?

What are the advantages and disadvantages of renewable energy in to climate change? Whatare the contributions of renewable energy to climate change?
