Is global warming really our fault?

Question

I read a lot and it seems the whole global warming thing is our fault theroy has more spending in washington then anything else so of course the government wants us to think its our fault I just want to know if there is an expert who can explain how it is our fault and not a natural proccess. thanks!

Answer 1

40 years ago...our infallible scientists said that we were going to cause an ice age. ORLY? Guess they were wrong?

Yes..the Earth's warming. yes, it's partially cyclical and partially because of sun-storms. Yes, it's partially because of CO2. And Part of CO2 is because of humans.

See Chart: http://www.telegraph.co.uk/news/graphics/2006/11/05/nwarm05.gif

In the first Earth Day in 1970, UC Davis’s Kenneth Watt said, “If present trends continue, the world will be about four degrees colder in 1990, but eleven degrees colder by the year 2000. This is about twice what it would take to put us in an ice age.” International Wildlife warned “a new ice age must now stand alongside nuclear war” as a threat to mankind. Science Digest said “we must prepare for the next ice age.” The Christian Science Monitor noted that armadillos had moved out of Nebraska because it was too cold, glaciers had begun to advance, and growing seasons had shortened around the world. Newsweek reported “ominous signs” of a “fundamental change in the world’s weather.”

Answer 2

If it was our fault the sea surface temperatures and atmospheric temperatures measured over the tropics would not have shown a cooling trend over the last four years. The tropics according to the AGW theory should show a warming trend in the troposphere 30% greater than the surface, a cooling trend in the tropics hardly supports Anthropogenic Global Warming.

Answer 3

Wow...this is the most nonsense and tripe I've ever seen on one page! Every theory and every 'fact' you see here can be put into perspective by simply remembering this...The Earth used to be in an ice age, then it warmed. This was way before Man arrived. T-Rex didn't drive an SUV. The few years we are able to look back amount to a pisshole in the snow compared to the age of the Earth, so no real context is available. The same people who rant about global warming were screaming about 'global cooling' just 30 years ago. Oh, and by the way...If the polar ice caps melt, the oceans will not rise. Water in either liquid or solid form displaces the same amount of space. Try filling a bowl with ice water right to the brim...The ice will melt, but the bowl won't overflow. This is 3rd grade tabletop science that the environmental wackos think we're too stupid to figure out.

Answer 4

Most experts do agree it is our fault. They (global experts) are meeting right now in Bali Indonesia to discuss what to do. You may want to read some news articles about it.

This quote is from one article at the conference...The Nobel Prize-winning Intergovernmental Panel on Climate Change said earlier this year that evidence for global warming was unequivocal, and without prompt action, the world could see irreversible effects, including desertification and extinction of up to 30 percent of plants and animals.

As time has gone by more experts have climbed on board.

Answer 5

yes it is. some people disagree and say it's just a weather pattern like the ice age, etc, but it is our fault. all the evidence found proves just that. all our gas-guzzling SUVs, trucks, and sports cars, plus our negligence in turning off electronics when we leave the room are just two of our contributions to global warming.

Answer 6

Mostly, yes.

Basically we know it's warming, and we've measured how much:

http://www.ncdc.noaa.gov/img/climate/research/2005/ann/global-blended-temp-pg.gif

Scientists have a good idea how the Sun and the Earth's natural cycles and volcanoes and all those natural effects change the global climate, so they've gone back and checked to see if they could be responsible for the current global warming. What they found is:

Over the past 30 years, all solar effects on the global climate have been in the direction of (slight) cooling, not warming. This is during a very rapid period of global warming.

http://news.bbc.co.uk/2/hi/uk_news/6290228.stm
http://www.pubs.royalsoc.ac.uk/media/proceedings_a/rspa20071880.pdf

So the Sun certainly isn't a large factor in the current warming. They've also looked at natural cycles, and found that we should be in the middle of a cooling period right now.

"An often-cited 1980 study by Imbrie and Imbrie determined that 'Ignoring anthropogenic and other possible sources of variation acting at frequencies higher than one cycle per 19,000 years, this model predicts that the long-term cooling trend which began some 6,000 years ago will continue for the next 23,000 years.'"

http://en.wikipedia.org/wiki/Milankovitch_cycle

So it's definitely not the Earth's natural cycles. They looked at volcanoes, and found that

a) volcanoes cause more global cooling than warming, because the particles they emit block sunlight

b) humans emit over 150 times more CO2 than volcanoes annually

http://volcano.und.edu/vwdocs/Gases/man.html
So it's certainly not due to volcanoes. Then they looked at human greenhouse gas emissions. We know how much atmospheric CO2 concentrations have increased over the past 50 years:

http://en.wikipedia.org/wiki/Image:Mauna_Loa_Carbon_Dioxide.png

And we know from isotope ratios that this increase is due entirely to human emissions from burning fossil fuels. We know how much of a greenhouse effect these gases like carbon dioxide have, and the increase we've seen is enough to have caused almost all of the warming we've seen over the past 30 years (about 80-90%). You can see a model of the various factors over the past century here:

This is enough evidence to convince almost all climate scientists that humans are the primary cause of the current global warming.

Answer 7

Yes - Everything man does causes global warming.

Even studying global warming causes global warming. Think about the planes and the helicopters needed to get people up to Greenland, and the bases that the scientist establish. What about the waste and pollution they cause?

There isn't a better reason to end global warming research.

Answer 8

it is a fault I'm not an expert but any little thing we do ( trash, chemical waist0 or any thing that compromise the environment is our fault basiclly the global warming

Answer 9

I would not question that it is human caused. Isn't every negative thing dealing with the world human caused? Larger populations, needing food, place to live and jobs have created needs to cut down forest, increasing the CO2 omissions.

The mining of coal and burning it in order to manufacture non-essential goods and to warm our homes and to produce electricity has caused increased CO2 omissions.

Almost everything we do on this earth is causing it to heat up. Cars, planes, manufacturing, electric plants, food production (farming), building of homes, forestry and so on and so on all adds to it.

You will not be able to get folks to stop doing what they believe they need to do in order to survive. Asia with its large populations and their increasing economy is not going to stop so that the world does not become over heated.

So once again it comes down to what is in it for ME. ME, ME, ME. That is the real problem in this world lack of compassion for our fellow man. It is everyman for himself.

Answer 10

i really dont think it is because before we were even alive there was an ice age and before the iceage there was a glbal warming so i think that it is just the earths cycle
