is there global warming caused by us?

Question

I just read in the April 7th issue of Science News page 214 that there is evidence of global warming on Mars from 1970's to the year 2,000. I wonder if our global warming is more a solar system phenomna caused by the sun than a global one caused by man

Answer 1

Yes, solar output has gone up around .2% in the last 40 years. Here's an article from 4 years ago and most people ignore these facts.

Answer 2

YES. Most unforunetly, yes. Man ( all of us together) for the last approx. 40 yrs. we have done it with, among other things, hair spray, smog, car exhaust,industrial pollution, with other things have punched a "hole" in the ozone layer in the atmosphere over the South Pole. Over the last 10-20 yrs. the "hole" has gotten much larger, over the Pole so that, among other things, unfiltered UV rays can come inside the atmosphere. to speed up the process of Global warming. The Polar ice caps are melting a LOT! faster now, so that in a few decades or so, the ocean levels WILL! rise and all the coastal cities will FLOOD and be under water. All the people there would move inland and many cities would Double or TRIPLE their size now. ALL! the low lying areas then would be like when Hurricane Rita came to "visit" New Orleans, except this time, she's coming to STAY. The water would NOT! go away. Wouldn't that BE FUN! Many! places would be like the Saints Dome was in New Orleans! We must stop this problem NOW! while we can (if we can). thank you. LIVE LONG AND PROSPER! STAR TREK LIVES ON.

Answer 3

this is a great question. some scientist beleive that global warming has to do with something called the maunder minimum, a phenomenon of the sun. however MOST scientists beleive that we are a major if not sole contributor to global warming. temperature records since the industrial revoloution indicate that scince we have been burning fuel for energy, the temperature of earth is heating up. this suggests that we are putting alot of gases that trap the suns heat into the atmosphere. only time will tell, but if i had to take a guess, i bet we are a big part of the problem. i hope this helps, and keep researching!!!!!!

Answer 4

That is really a question for the Environment & Ecology section.

But the short answer is that there is evidence for both outside and man made causes.

Answer 5

Yes, it's caused because we burn fossil fuels--hence we create gasses, which make a greenhouse effect, destroying the Ozone and allowing UV Rays from the sun to penetrate and hence warm the planet

Answer 6

The amount of energy we produce is less than 1% of what we receive from the sun.

Answer 7

It is caused by a disappearing ozone layer, a great influx of carbon dioxide, and Chlorofluorocarbons.

Answer 8

I don't think that it is us 100% I think that part of it is natural and caused by the sun. But we are still doing are fair share of the dammage.

Answer 9

Yes it is.
