Numerous Studies have shown a correlation between CO2 Emissions and the World's temperature. What's more, this time, correlation=causation. A tiny amount of CO2 and other greenhouse gases, like methane and water vapour, keep the Earth’s surface 30°Celsius (54°F) warmer than it would be without them. We have added 42% more CO2 but that doesn't mean the temperature will go up by 42% too.
There are several reasons why. Doubling the amount of CO2 does not double the greenhouse effect. The way the climate reacts is also complex, and it is difficult to separate the effects of natural changes from man-made ones over short periods of time.
As the amount of man-made CO2 goes up, temperatures do not rise at the same rate. In fact, although estimates vary - climate sensitivity is a hot topic in climate science, if you’ll forgive the pun - the last IPCC report (AR4) described the likely range as between 2 and 4.5 degrees C, for double the amount of CO2 compared to pre-industrial levels
All over the world, people are seeing weather patterns that are new to their environment. Snow where there didn't used to be snow, temperatures that are hotter than normal, or colder than normal. The term 'global warming' does not mean that everyone will notice warmer temperatures. Many places will feel colder weather patterns. Global warming simply means changing weather patterns caused by the melting of the polar ice caps. The fact that those things are happening cannot be denied.
that is one huge place without a heating system. can you imagine the temperature in the winter? a comfortable 70-80 degrees. how? every person that goes in there heats up the place. a huge building is heated up by body heat. well.. try the same thing but on a bigger scale.. earth with over 6billion people.. same effect. makes sense to me.
Global warming is present with the holes in the ozone layer. The fact is that in the Arctic there are fewer icebergs and that the Arctic itself is shrinking. There are unusual climate changes happening throughout the world. People of the world will not believe that global warming exists until it starts affecting the region they live in.
Evidence for the existence of global warming and other forms of climate change is not limited to the fact that the proportion of credentialed scientists who dispute the phenomenon is vanishingly small (and sometimes receiving corporate funding), although the consensus is indeed overwhelming. The point is also that huge numbers of independently conducted studies around the world have confirmed it. Then there are other statistics. Nine of the ten hottest years on record have occurred since 2000 (source: http://www.economist.com/blogs/dailychart/2010/12/climate_change), including the hottest year yet, 2010. The conspiratorial interpretation of concern about climate change flies in the face of even the evidence that emerged from the deniers' dream scenario, when the University of East Anglia's Climatic Research Unit's leaked e-mails failed to dredge up any fraud in 2009. One may reasonably oppose particular climate change mitigation policies like cap and trade, as Bjorn Lomberg does; one cannot deny the science.
Even people who do not believe that humans are the cause of global warming cannot deny that it exists! Scientific research has proven that we are currently in a climactic warming shift. Whether it is because of human beings or part of a normal climactic cycle is still debatable but the evidence has convinced me that it is caused by the actions of human beings.
Global warming exists because there is enough evidence to prove that the earth is getting deteriorated through the ignorance of human beings about the care of the environment. Growing population in many nations, lack of space, lack of resources for water, food and shelter is leading us to misuse our natural resources. While technology helps us to do things more efficiently, it has also lead to over use of energy for example, water, electricity. We are not doing enough to protect the environment by saving water, energy and recycling waste.
There is such thing as global warming due to the fact that weather patterns have changed greatly from 50 years and more ago. Today, the weather patterns are erratic, and we do not know when one storm will form and another storm will diminish. Global warming has caused temperatures to rise and thus, produce more deadly hurricanes and currents all around the world. The ozone layer is getting depleted as we speak and there is nothing worse than the temperature scorching our skins.
We know that polar ice is melting. We have huge chunks of ice breaking away more and more frequently. Tons of fresh water is pouring into our oceans. Our weather patterns are changing. We experience evidence of that every season when we see a noticeable change from the same time each year prior. There is an obvious overall climate change taking place. All we have to do is open our eyes and observe to see that. It doesn't take a scientist to notice this. We would be seeing and talking about it if we had no technology at all. It is that obvious.
To believe that this will have no effect on the natural phenomena of the planet is being ignorant. One only needs to look towards China and its unabated emission of pollution to see the effects it has on its surrounding environment. Over a third of China is plagued by acid rain caused by sulfur dioxide pollution. During the 2008 Olympics, Beijing was scrambling to improve the air quality to bare minimal acceptable levels. Up in the polar icecaps, there is clear evidence of the melting of icebergs due to the greenhouse warming effect. This in turn will eventually raise the levels of the oceans, causing more volatility in the weather. In conclusion, we cannot ignore these obvious signs and try to rationalize the problem as not being attributable to the actions of man. We should try to reverse the trend while we still have a chance.
All of you who believe in this crap, are idiotic! There is NO such thing as Global Warming! We're NOT gonna die in 2012 because of it! SO STOP SAYING THAT! ITS A BUNCH OF CRAP! Scientists are just trying to scare people! They don't know anything about it!
Global warming is yet to be proven, and yet the government uses it as an excuse to raid our wallets. The argument you should be having is first proving it exists, and then taxing appropriately. The trouble is, it is easy for them to get away with it because there are so many "tree huggers" who believe this. It's Easter time in the U.K., and it is snowing outside.
We can give global warming a name, but whether we caused it is another question. Its a cycle of the earth and although we might contribute to it's speeding up, we did not start it. Our pollution is an iota of what can happen (as has been documented) when a large meteor hits the earth.
The term global warming could have easily been called something else which better defines the process which the earth shifts its climate control to a different policy.
I believe that people are blowing man-made global warming out of proportion, and governments have run with this "crisis". They have run with this crisis to gain more power through taxes, such as cap and trade and the carbon tax. With this said, I do believe it is not a bad thing to try to change our polluting habits. With all this said though, I do believe that the earth is getting warmer. But, I believe this is due to factors with the sun, not with carbon emissions.
Sure we could speed it up a little bit, no doubt about it. But that doesn't mean we CAUSED it. Even the top scientist on the matter says we don't have a measurable effect on the rising and cooling of the earths interior. Just a few decades ago we were worried about another ice age, now this. Humans are just paranoid. There is evidence that, yes the world is getting hotter, but it's not us, it's a natural cycle, and it's happened many times before. Not only is the issue not worthy of ANY of the attention it's getting, it's hardly an issue at all, just a small nuclear war, would reverse all the global warming for nearly ten years!
They've been talking about global warming for years now and every year is colder than the year before. So if global warming does exist can you tell it to hurry because we're all freezing up here in Minnesota! In fact 2014 will go down as one of the coldest snowiest winters in recorded history!
In the 70's it was global cooling and that didn't pan out so then it was global warming and then the GW "scientists" got busted taking kickbacks to skew there research toward the progressive global warming view. Now we have climate change, DUH! It's not man made, it's the planet stupid! Change happens. Oh, then there was the idea that cattle gas was worse than car exhaust... Really? Imagine what it was like when the dinosaurs lived. Yes, we need to be aware and good stewards of our dirt, water, grass and pets, but get a life you tree hugging planet lovers. One degree change isn't something to get irate about, not even several degrees is worth it. I'll drive what I want, burn wood if I want and work at the factory I want. Besides, even if America went cold turkey "green", Russia, China, N. Korea, all Arab countries and many others will tell you to pack sand and then slit your throat. Mind your business and I'll do the same, thank you.
I don't know if you have eyes or hands, but I do, and they are freezing. School was canceled because there wan't no weather to let us walk, -30 DEGRESS KELVIN.
Sure doesn't seem like warming to me. I mean, if it was GLOBAL WARMING, then wouldn't the entire world be getting warm. It's colder than it has been since 78 save for in Florida, maybe we should just call it "AROUND THE EQUATOR WARMING" hahahahaha
The preposterous notion that CO2 is responsible for climate change can be easily debunked by doing a little research on volcanoes. A volcano can output MASSIVE amounts of so called greenhouse gases, including insane amounts of CO2. Even if you increased industrial plants 1,000 fold and put 6 billion more SUV's on the road it could never amount to what a volcano can output with a sizable eruption.
Then lets point out that the warmest year on record remains 1938. Moreover we are clearly entering a 20-30 year cooling trend just as we had a 20 year warming trend during the 80's and 90's. Global Warming is a political agenda driven by money and environmentalists who are desperate to force their agenda down your throats and into your wallets.
69% of you have been duped by politicians and bad scientists. In Science all data and theories are presented for close scrutiny. In the climate change community this simply does not happen. They either refuse to disclose their evidence or outright falsify results. This has been caught on multiple occasions.
Don't let yourself be fooled by people who will not reveal their evidence and will not tell you that mother nature produces more CO2 and so called greenhouse gases than the entire human race could ever hope to achieve in a thousand years.
I don't deny that man produces more CO2 than in the past but I do not believe it is a source of global warming. Scientists such a Roy Spencer and even one of the creators of the myth from NASA have said it's not happening. From a logical point of view, more warmth would cause more clouds, block the sun, and equalize the temperature. Man also has greatly increased the amount of greenery around the planet (mostly in the US) which absorb the CO2.
The temperature has not increased in 15+ years and that's along with an increase in solar activity.
Finally, there have been 74 climate models in the past 30 years. 100% of them have greatly overestimated temperature increases. Not one underestimated it. There are graphs on the internet that illustrate this. The science has gone political and when you have funds from the government pushing scientific theories, you will often get results to prove those theories.
