what is the scientist's point of view of global warming?

Question

what are the scientific causes and effect of global warming?

Answer 1

This is a statement from the Union of Concerned Scientists:

"Global warming is one of the most serious challenges facing us today. To protect the health and economic well-being of current and future generations, we must reduce our emissions of heat-trapping gases by using the technology, know-how, and practical solutions already at our disposal."

Answer 2

Scientific reason: greenhouse gasses such as CO and CO2 prevent IR radiation from escaping from the earth atmosphere. And NO THESE ARE NOT THE SAME GASES THAT DRILL HOLES IN THE OZONE LAYER. Normally, this greenhouse effect is a good thing. It help the earth maintain its temperature to some extent (think ice age). But with the increasing rate of fossil fuel burning, and the reduction of the forested areas, the oxygen/CO2 cycle is at an imbalance state, with increasing amount of these greenhouse gases causing the global warming effect.

Effect of the global warming: Increasing temperature and temperature gradient throughout the globe. These will result in (and not limited to):
- Storms (with increasing strength)
- Heatwaves
- Raising of the sea level
- Ecological consequences (mating cycles, flowering cycles, which rely on the season might have shifted, which can cause some species to be extinct, while another might thrive)

Answer 3

My personal opinion that Global Warming is caused by solar heat & activity, but many leading scientists imply that humans are the cause of it. I find this to be lacking in facts and is simply a spun up theory. There is a much more likely chance and recently more accepted that is the natural cycle of the planet Earth.

Answer 4

Indeed "global warming" is the Libs new religion. It has all of the same hallmarks of many old religions: you can't prove any of it untill after you're dead, it calls for all of us to make drastic sacrifices right now that the movement leaders are, of course, exempt from having to make also (lowering carbon footprint, not driving gas burning cars, etc, etc.). The libs would rather live in denial of an imminent threat like Islamo-fascism that looms in our present time and is currently killing real PEOPLE that we can see. They would rather spend their childrens college funds and their retirement saving to "fight" an event that can't be proven, that most likely will not happen several humdred years from now. Just the same way Hitler said he was going to do everything he did BEFORE he did did it and very few choose to listen and believe him is the same way evil men of todIay are doing the same. Hitlers' book "mine kompf" translates to mean "my struggle". Doesn't "jihad" translate to mean the exact same thing? (No it doesn't translate as "Holy War". It translates to mean "struggle between good and evil") I might make some people upset by my next statement but this is an example of "woman thinking". "Let's feel good about doing something that might help save the children of tomorrow from some nebulous calamity that is sooooo scarey instead of actually confronting evil PEOPLE today that have already killed THOUSANDS! They feel powerless in the face of an actual opponant that is a person. They feel good about fighting a situation that has no face, nor tangible effect. It's really easy to wave my arms and say I'm doing something. I may be burning lots of calories and LOOK really busy but it's not the same as actually lifting a box and moving it from point A to point B. To them the FEELINGs are more important than the FACTS. Feeling good about saving the planet is more important to them than saving our hides. Sure I'm all for not polluting and cleaning up the environment but if I'm getting shot at while I'm planting trees I think somewhere the #1 priority has gotten confused. If we lay down and die for these people, you think they'll cherish the Earth and combat global anything??? Have you seen any of the countries these people come from? In my opinion, the Global Warming conspiracy/Cult is an anti-human, anti-capitalism anti-progress, sociatal suicide machine that will only serve to return human kind to the stone age. Isn't this the same mentality that brought 1000 years of the dark ages in Europe??? Maybe the survivalists were right after all. Hmm... on that note I have to go. I have to order that bomb shelter and start digging up my back yard. The liberals are coming and they are promising to let in all the killers and then take away my constitutional right to arm and defend myself while they take away my constitutional right to hear someone elses opinion and then to express my own. Then they will outlaw the kind of lightbulb I can use (because it has too big of a carbon footprint) and force my to pay an offset tax because carbon dioxide was been deemed a pollutant and I can either stop exhaling for the rest of my life or pay through the nose for my right to breath out of it.

Answer 5

Frankly I am starting to wonder about the whole global warming theory. For a good perspective, read Michael Crichton's book, "State of Fear". It makes you re-think all the positions you may have had on environmental topics. Granted, I realize that it is a work of fiction - but it is still interesting to read.

Answer 6

due to the green house effect the heat of the sun gets trapped in the earths atmosphere. this leads to rise in temperature . one of the effect of global warming is the melting of ice on the antartic and artic circle.this in turn has lead to the rise in the water level in sea( as watre occupies more space than ice). also the average temperature of the earth has increased.

While Nature still may be the best for certain biochemical and genetic topics, it surely has lost it on global warming. My antennae went up on this one in 2003 when my colleague, Robert Davis, and I submitted a paper to Nature showing that, as our cities have warmed, heat-related mortality declined significantly as people adapted to the change. They declined to even send it out for review; but after it was accepted in International Journal of Biometeorology it was awarded "paper of the year" by the Climate Section of the Association of American Geographers. Something is clearly amiss. Nowhere is that more clear than in a paper, "Widespread Amphibian Extinctions from Epidemic Disease Driven by Global Warming," by J. Alan Pounds, that appeared in their January 12 issue. We'll put it simply: with regard to global warming papers, the review process at Nature is dead. Gone. Kaput.

"The Sahel," in the words of Anyamba and Tucker (2005), "is a semi-arid region stretching approximately 5000 km across northern Africa from the Atlantic Ocean in the west to near the Red Sea in the east and extending roughly from 12°N to 18°N," which "forms an ecological transition between the Sahara desert to the north and the humid tropical savanna to the south (Le Houerou, 1980)." It was recently featured in a special issue of the Journal of Arid Environments entitled "The 'Greening' of the Sahel," which describes its recovery from what Hutchinson et al. (2005) describe as a run of "several devastating droughts and famines between the late 1960s and early 1990s."

During the past 6000 years, the temperature variation trend inferred from d18O of peat cellulose in a peat core from Hongyuan (eastern Qinghai-Tibet plateau, southwestern China) is similar to the atmospheric 14C concentration trend and the modeled solar output trend. The general trend of Hongyuan d18O during the past millennium also coincides well with the atmospheric 14C concentration trend, the 10Be concentration trend in an ice core from the South Pole, the reconstructed total solar irradiance trend, as well as the modeled solar output trend. In addition, temperature events also correspond well to solar perturbations during the past 6000 years. Therefore, the driving force of Holocene temperature variations should be properly ascribed to solar activity. The spectrum analysis further illustrates that quasi-100-yr fluctuation of solar activity was probably responsible for temperature variations in northeast Qinghai-Tibet plateau during the past 6000 years.

Answer 8

O aquecimento global causa muito dano à atmosfera.

Answer 9

humans have a part in it. the normal cooling and heating cycle is the base but the production of CO2 ups the ante

Answer 10

This is because the people are using air-condition, cars, vehicle and all the stuff producing heat. Mostly smokes. It create heat and stuff.
