What proof do you have that global warming is real?

Question

You liberal rouge crazies.

Answer 1

Global warming is the observed increase in the average temperature of the Earth's atmosphere and oceans in recent decades.

The Earth's average near-surface atmospheric temperature rose 0.6 ± 0.2 °Celsius (1.1 ± 0.4 °Fahrenheit) in the 20th century. The prevailing scientific opinion on climate change is that "most of the warming observed over the last 50 years is attributable to human activities".

The increased amounts of carbon dioxide (CO2) and other greenhouse gases (GHGs) are the primary causes of the human-induced component of warming. They are released by the burning of fossil fuels, land clearing and agriculture, etc. and lead to an increase in the greenhouse effect. The first speculation that a greenhouse effect might occur was by the Swedish chemist Svante Arrhenius in 1897, although it did not become a topic of popular debate until some 90 years later.

The measure of the response to increased GHGs, and other anthropogenic and natural climate forcings, is climate sensitivity. It is found by observational and model studies. This sensitivity is usually expressed in terms of the temperature response expected from a doubling of CO2 in the atmosphere. The current literature estimates sensitivity in the range 1.5–4.5 °C (2.7–8.1 °F). Models referenced by the Intergovernmental Panel on Climate Change (IPCC) project that global temperatures may increase between 1.4 and 5.8 °C (2.5 to 10.5 °F) between 1990 and 2100. The uncertainty in this range results from both the difficulty of estimating the volume of future greenhouse gas emissions and uncertainty about climate sensitivity.

An increase in global temperatures can in turn cause other changes, including a rising sea level and changes in the amount and pattern of precipitation. These changes may increase the frequency and intensity of extreme weather events, such as floods, droughts, heat waves, hurricanes, and tornados. Other consequences include higher or lower agricultural yields, glacial retreat, reduced summer streamflows, species extinctions and increases in the ranges of disease vectors. Warming is expected to affect the number and magnitude of these events; however, it is difficult to connect particular events to global warming. Although most studies focus on the period up to 2100, warming (and sea level rise due to thermal expansion) is expected to continue past then, since CO2 has an estimated atmospheric lifetime of 50 to 200 years. . Only a small minority of climate scientists discount the role that humanity's actions have played in recent warming. However, the uncertainty is more significant regarding how much climate change should be expected in the future, and there is a hotly contested political and public debate over what, if anything, should be done to reduce or reverse future warming, and how to deal with the predicted consequences.

Answer 2

Dang Christi, break it down! You gave a logically informative answer. I totally support your answer.

I don't think liberal or conservative has anything to do with science. So get a grip, I don't see any Bush or Clinton "people" going to University for physics. I think most of it goes over their heads.

With that said, there are CO2 deposits that have been trapped in the ice glaciers of the Artic for millions of years. When we take samples of these deposits, we discovered a time table that directly links man kind with the increase of CO2 in the atmosphere. The ice is like an antient foot print, rich with history.

CO2 as Christi said, is directly linked to keeping the world warm. It is common sense to think that increasing the amount of CO2 in the atmosphere would increase the warmth of the earth. We do show average temperature increases that have been recorded. This does not include the times when weather was NOT recorded, daily.

If you look at CO2 as a blanket, it only makes sense that if you apply more blankets it will become hotter. Do you follow?

I can't make it any easier then that. There are other types of greenhouses gases that exist that are basically man made in a lab. CFCs is one of them. (what use to be used in A.C.s and other things) They have been banned by the Montreal Protocol that went in to effect in the 90's. It is not that every house in the world has A.C. that is the problem. It is that CFCs hold 10,000 times more infared heat then CO2. Not to mention the fact the CFCs can travel to the ozone layer of the atmosphere and lock on to O3 (which is ozone) depleting this very percious resource.

I certainly hope you understand all this.

Good Luck and Take Care

Answer 3

Global warming is very real!
That said i can give u the most recent example from siberia where the "permanent forst" are melting. These frozen landscape were like that for 15,000 years but are slowly melting leading to the rise of methane, a gas that contributes to warmth anyway. The cause of this warming is obviously co2, NH4, etc and scientist know that.
But, YOUR question i think is about whether the climate can turn catastrophic DUE to global warming. THe answer is "we dont know" FULLY. But all we know is that the warming of the ocean does contribute to higher number of tropical storm to Hurricanes.

Answer 4

I have been to Alaska a few times, and in the 15 years total that I have made trips I have seen entire Small towns have to move from what was solid ice pack back 500 feet and more because of melting. These folks have also had Polar Bear troubles that they have never had before because the bears cannot go out onto ICE FLOWS to hunt like they used to.
So for my friends, who do not read Science Journals! AND ARE PROBABLY NOT INTERESTED IN TRYING TO READ THEM . FACT is that Global Warming is really destroying their homes and hunting grounds!!!!!!!!!!
Screw the Scientists, hunger is a much more solid warning for my friends!

Answer 5

Im not liberal, but there is proof of warming, take for instance, the tsunamis that hit, the hotter and drier summers, lack of water and more pollution in the air. I dont recycle and I probably should, but I think everyone should make a conscience choice on how we can help our air and preserve our trees for our children.

Answer 6

There is no doubt that "global warming" is real. The REAL question is (A) whether or not it is caused by man, or just a natural phenomena. And (B) is there anything we can really do about it.

Answer 7

The only proof I have is what they say on TV.
Maybe some day I will hop in my car and go take a look at the glaciers myself
and make sure their not melting
I might feed some Polar Bears while I'm at it
so I'll make sure I bring plenty of fish.

Answer 8

What 99+% of climate scientists who've studied it think.

http://www.sciencemag.org/cgi/content/fu...

"Such statements suggest that there might be substantive disagreement in the scientific community about the reality of anthropogenic climate change. This is not the case."

"Politicians, economists, journalists, and others may have the impression of confusion, disagreement, or discord among climate scientists, but that impression is incorrect."

All scientific articles in peer reviewed journals that contained the words "climate change" from 1993-2003 were surveyed. 928 of them. The number of articles that said global warming was not happening.

Zero.

Answer 9

birds migration patterns and nesting habits are changing and taking place at the wrong time of year due to the warming. The birds are confused as to WHAT season it is due to the warmth.

Answer 10

The carbon dioxide CO2 concentration in the atmosphere is higher than in the past few million years and the glaciers are retreating. Big Oil doesnt want you lemming rwingers to believe it though. Not good for their bottom line.
