It is absolutely and issue and to say that it is not is to deny basic facts about science.

-Sea level rise is being measured; that's a fact that has been observed all over the world.

-Glaciers are retreating, and ice caps are melting at an alarming rate; that has been observed all over the world over the last century.

-CO2 is a greenhouse gas that traps solar radiation; that is a fact that exists all over the universe including here. The Planet Venus has active geology, which has given the planet what Astronomers call a "runaway greenhouse effect." The Average Global Temperature on Venus is around 900 degrees fahrenheit. It is hotter on Venus than it is on Mercury, which is MUCH closer to the sun. So, we know CO2 traps heat; that is not up for debate.

-Earth naturally has CO2 in its atmosphere because Earth has active geology (not nearly as active as it is on Venus); that is why the planet is inhabitable at all, and isn't -200 degrees at night and +300 during the day. So, we know what CO2 does, factually.

-CO2 comes out of your car's tailpipe; that is a fact that everyone should know by now. CO2 also comes out of smokestacks and industry. We know that; it is not up for debate.

-CO2 levels have risen exponentially since the industrial revolution (when we started using fossil fuels for energy on a wide scale). This is not a conjecture. It has been observed. Today we have levels of CO2 that the planet has not seen in over 800,000 years, when we had a much more active geology and no broadleaf vegetation.

-The AGT of Earth has risen at the SAME exponential rate as the CO2 levels starting at the same time, almost like magic, except it's science; this has also been observed.

-We are seeing a mass extinction beginning as a result of climate change. It will likely be every bit as bad as what happened to the Earth when the dinosaurs were killed. My friend who is a scientist at a University in Florida is doing research on this very topic, and he is seeing it for himself in the everglades.

Most of the arguments against all this evidence are from people that either do not understand the science and evidence behind it, or it does not fit their political views, so they reject it. The problem is, whether you are a Republican or Democrat, you still live on the same planet and scientific laws and theories still apply to you. This is one of those times when "conservatives" should stop denying science or they risk becoming irrelevant and going the way of the whig party.

98% of scientists with PhDs from all around the world are not denying these truths because it would be stupid for them to. Since 2012, there have been around 2500 peer-reviewed scientific journals that were written by over 9000 respected scientists. ONE of them denied climate change.

Everything I said about climate change can be found on NASA's website: http://climate.nasa.gov/evidence/ It can also be found on ANY reputable science website. None of this is made-up conjecture. I don't care what party you belong to, facts are facts, and we are seeing it happen. It isn't a hypothesis. The theory regarding CO2 trapping heat has been around since the 1890s, so this theory is nothing new; now we just have a century of evidence, and evidence from other planets, to corroborate it.

Denying that global warming is a problem is absurd at this point. We see it happening, and it has been happening.

To deny it, you would have to:

-Deny that CO2 traps heat, which it does on earth and on other planets, which is observable.

-Deny that sea levels are rising, which is an observable fact.

-Deny that glaciers are retreating, which is an observable fact.

-Deny that heat melts ice, which it does on your counter when you set an ice cube on it; you can watch that happen in your home.

-Deny that there is a mass extinction happening, which is observable.

-Deny that CO2 levels are rising, which is observable.

-Deny that the Average Global Temperature of Earth is generally rising, which is observable.

Again, any reputable scientific website will explain everything I just said. If you don't believe me, hopefully you'll defer to the brilliant minds that put a man on the moon: http://climate.nasa.gov/evidence/

If you do not have a PhD in science and think you know more about science than NASA, you're pretty much beyond my help.

There has been no scientific evidence that global warming is happening. In fact studies have showed that the earth is getting colder. In the 70s scientist predicted that there was going to be another ice age. Climate models showing global warming have been wrong over and over. Predictions about the impact of global warming have already been proven wrong. If anything almost all the evidence points away from global warming.

Not according to NASA and every other credible scientist on the planet who know more about science than you.

http://climate.nasa.gov/evidence/

In the 70s scientist predicted that there was going to be another ice age.

What is your point? That does not refute all the overwhelming observable evidence that supports that the Average Global Temperature is in a general upwards trend, and it does not dispute the fact that CO2 is a green house gas, and that is not only observed on earth, but also on other planets.

Climate models showing global warming have been wrong over and over.

Some in the past that were hypothesizing were eventually disproven because that's how science works. That means science is right, that does not disprove scientific facts. It shows that science is capable of amending its consensus when facts are presented. Presently, there are no facts that are refuting all the undeniable observable evidence that support the theory of Global Warming.

Predictions about the impact of global warming have already been proven wrong.

This is patently false. We are seeing sea level rise (part of the prediction), we are seeing mass extinction underway (part of the prediction), we are seeing air that is unhealthy to breathe (part of the prediction), and we are seeing a general warming trend in the AGT (part of the prediction).

If anything almost all the evidence points away from global warming.

You shouldn't be telling me this. If you really think you're right, call NASA RIGHT NOW, and tell them you've proven all the scientists in the world with credibility wrong! Go now! You will change the world!

Well well well, where do I start? Before you go talking about the basic facts of science, you should learn some for yourself.

-Ice caps are, in fact, not melting. At all. They are increasing. Arctic ice has gone up 50% since 2012. That's 1.7 million square kilometers.

-Instead of talking about other planets, why don't you talk about Earth, THE PLANET WE LIVE ON and also know the most about.

-To say that the fact that CO2 contains heat is not up for debate is just ignorant. Earth's atmosphere is 0.03% CO2 and approximately 1% water vapor. Water vapor has a higher specific heat. A high specific heat means that it takes more energy to heat something up, thus maintaining that heat for longer. A low specific heat is the opposite. So if water vapor maintains heat for longer and there is exponentially more water vapor than CO2, why isn't water vapor something to worry about?

-Yes, CO2 comes out of cars and factories. This is simply a fact with no further explanation.

-Even with those so-called increases in CO2, it is still only 0.03% of the atmosphere. THAT, by the way, is a fact.

-The temperature of the Earth has not changed in 17 years (since 1997).

-Those that say the polar ice caps are melting, polar bears are dying, and the sea level is rising are completely wrong. I mentioned above about the polar ice and how it has increased 50% in only two years. As for the polar bear population, it has more than doubled in the past thirty years. As for the sea level rising due to the ice caps melting, it is impossible. Even though it is a proven fact that the ice caps have expanded rapidly, let's just say for argument's sake that they were melting. Imagine that you have a half of a cup of water. Now add some ice to that water. You will notice that the water level will rise. Well when that ice melts, the water level goes back down. It would be just silly to say that the cup will overflow from the melting ice.

-Scientists predicted about 15-20 years ago that in the near future, we would have to wear special suits to protect us from the heat. We are obviously not walking around with crazy suits to protect us from heat.

-Those who claim that Earth is a giant greenhouse are also wrong. Earth is by no means a greenhouse. A greenhouse is surrounded by glass and traps heat inside. Earth is obviously not surrounded by glass. When clouds form, they reflect heat back into space. This is Earth's way of cooling itself down. So we could not heat up the Earth if we tried. This is why when you are outside on a hot summer day and a cloud rolls over your head and blocking the sunlight, it instantly feels cooler. The heat is being reflected back into space by the clouds.

-If you're wondering why the THEORY of global warming has become such a widely accepted theory, go ahead and look into Climategate. It is a scandal literally showing that scientists have lied about global warming.

-Don't believe everything you've ever heard or what has been brainwashed into peoples' brains.

Well well well, where do I start? Before you go talking about the basic facts of science, you should learn some for yourself.

I know plenty about science, and I have friends who do research for Universities in the field. I've also taken a bunch of classes in Astonomy and Earth Sciences. Moreover, all of the basic facts I've mentioned are also the basic facts accepted by NASA, who, I'm assuming probably know more about science than both of us.

-Ice caps are, in fact, not melting. At all. They are increasing. Arctic ice has gone up 50% since 2012. That's 1.7 million square kilometers.

Not true, at least, according to NASA and every other credible scientific source in the world, and pictures of the ice caps from space. If you think you know more about science than NASA, I don't know what to say to you. http://climate.nasa.gov/evidence/

-Instead of talking about other planets, why don't you talk about Earth, THE PLANET WE LIVE ON and also know the most about.

The reason I brough up Venus is to show that the greenhouse effect is not some strange anomaly that only happens on Earth. So, I WAS talking about Earth, but I mentioned Venus to illustrate that the greenhouse effect happens other places too, and it universal.

-To say that the fact that CO2 contains heat is not up for debate is just ignorant. Earth's atmosphere is 0.03% CO2 and approximately 1% water vapor. Water vapor has a higher specific heat. A high specific heat means that it takes more energy to heat something up, thus maintaining that heat for longer. A low specific heat is the opposite. So if water vapor maintains heat for longer and there is exponentially more water vapor than CO2, why isn't water vapor something to worry about?

CO2, does not contain heat. CO2 TRAPS heat, and it does it on every planet that has CO2 present in its atmosphere, like Venus and Earth. It is actually ignorant to deny that. Here's what those "idiots at NASA" that you seem to think you know more about science than say about it. I am assuming that you just do not understand the science behind it. Please read what NASA has to say and how they know what they know: http://climate.nasa.gov/evidence/

-Yes, CO2 comes out of cars and factories. This is simply a fact with no further explanation.

Okay. So you DO see the problem then.

Even with those so-called increases in CO2, it is still only 0.03% of the atmosphere. THAT, by the way, is a fact.

Those "so-called increases" are actually measurable. Here's what NASA scientists say about it: http://climate.nasa.gov/evidence/

-The temperature of the Earth has not changed in 17 years (since 1997).

Actually, the general upward trend in the Average Global Temperature (AGT) continues, just as it has since the Industrial Revolution and the advent of burning fossil fuels on a large scale. Here's what NASA scientists have to say: http://climate.nasa.gov/evidence/

-Those that say the polar ice caps are melting, polar bears are dying, and the sea level is rising are completely wrong. I mentioned above about the polar ice and how it has increased 50% in only two years. As for the polar bear population, it has more than doubled in the past thirty years.

Even though it is a proven fact that the ice caps have expanded rapidly, let's just say for argument's sake that they were melting. Imagine that you have a half of a cup of water. Now add some ice to that water. You will notice that the water level will rise. Well when that ice melts, the water level goes back down. It would be just silly to say that the cup will overflow from the melting ice.

You're wrong that the polar ice caps are not melting. They ARE in fact melting, and we know that because we can see it happening. The ice in a cup of water analogy is an over-simplification intended to make the rising sea levels (something we've measured) from seeming like it could be happening, but it is, and the ice caps ARE melting, and so are the glaciers and permafrost, which is what is actually adding to the sea level rise. Here's what NASA scientists say about it. Please read what they have to say. They are brilliant scientists who have a higher level of knowledge about science than you:

http://climate.nasa.gov/evidence/

-Scientists predicted about 15-20 years ago that in the near future, we would have to wear special suits to protect us from the heat. We are obviously not walking around with crazy suits to protect us from heat.

I do not recall that. Do you have a source? Any reputable scientists knows that it is happening, but not as quickly as that. Here's what NASA scientists have to say, please read it so that you understand the science about this. They know more about science than both of us: http://climate.nasa.gov/evidence/

This is why when you are outside on a hot summer day and a cloud rolls over your head and blocking the sunlight, it instantly feels cooler. The heat is being reflected back into space by the clouds.

That's not how it works entirely. You've oversimplified how the environment works. No one is saying that the Earth is a greenhouse. The Greenhouse Effect is something that happens, but the earth is not a greenhouse. The greenhouse effect is something scientists have named the effect that CO2 has on trapping heat on a planet and keeping it warm. If we did not have a natural greenhouse effect, it would be uninhabitable and cold at night, and too hot during the day to live. So, the trapping of heat that happens naturally with the Earth's geology is why the planet has maintained a habitable temperature.

-If you're wondering why the THEORY of global warming has become such a widely accepted theory, go ahead and look into Climategate. It is a scandal literally showing that scientists have lied about global warming.

Why did you type "theory" in large letters? Anyone who knows anything about science (something you've tacitly claimed to know more about than me), knows that a theory is actually one of the highest standards something in science can attain. So, calling something a theory is saying, "it's true." You're thinking of a HYPOTHESIS, and Global Warming is NOT a hypothesis. It was a hypothesis back in the 1890s before they had data to back it up with, and now it's a theory. Scientists are not lying about global warming. It's happening. Some right wing political interests are lying about global warming to ignorant people who do not understand science. Here's what NASA scientists have to say about it:

http://climate.nasa.gov/evidence/

-Don't believe everything you've ever heard or what has been brainwashed into peoples' brains.

Science is not a lie. Science is not made-up. Science is not a "liberal" conspiracy. Science is man's epistemological study of the universe which uses a method that relies on empirical evidence. The opposite of science is superstition. Scientists are not there to lie to you. Scientists are there to learn and research using factual, empirical evidence. It is not politically-driven.

In reality, credible scientists are not even debating if this is happening, or if CO2 traps heat in an atmosphere. To actual scientists all around the world, that's not a debate. Only people like you are debating it. So, before you go telling other people to "learn some basic facts of science," you should probably take a few community college science classes so that you can learn how science works, or at least read what experts in science have to say so that you understand the whole idea before you attack it: http://climate.nasa.gov/evidence/

Sadly, I am afraid you're more politically driven, than interested in how science works. Please, look at the NASA link. Any other reputable science website that is about science will agree with their findings. This is not a secret conspiracy to take your gas-guzzling truck. It's science. If you think science is an international conspiracy, or if you think that you know more about science than the brilliant scientists at NASA, or anywhere else in the world, I'm not sure I'll be able to lead you out of the cave though (that's a Plato reference).

The temperature of the Earth has not changed in 17 years

The trend involved is actually the Global Mean "Surface" Temperature - which specifically excludes the known increase in sub-surface ocean temperatures. Are you trying to be misleading, or, have you been misled by someone else?

Additionally, the GMST data was initially calculated using estimates for artic temperatures based on only 4 data sites, more complete satellite data shows those estimates were far below the actual artic warming over the relevant period. So, not only has GMST increased, it does not include other known warming.

why isn't water vapor something to worry about?

Water vapor forms clouds, and clouds with high albedo can have some negative feedback effect.

CO2 can stay up in the atmosphere for centuries, but for water vapor it is typically a few days.

Water vapor also doesn't cause forcing the same way.

You are describing melting sea ice, not ice that is on land.

Try this experiment:

Get a bowl (not the one you've been smoking, a normal bowl),

Fill about half of the bowl up to the brim (or higher even, doesn't matter) with dirt - this simulates land, preferably it should be roughly flat or slightly inclined downwardly toward the water,

Fill the rest of the bowl up to the brim with water - (the sea)

Now, put ice on top of the exposed land.

What happens when the ice melts??

The cost and benefits of global warming will vary greatly from area to area. For moderate climate change, the balance can be difficult to assess. But the larger the change in climate, the more negative the consequences will become. Global warming will probably make life harder, not easier, for most people. This is mainly because we have already built enormous infrastructure based on the climate we now have.

People in some temperate zones may benefit from milder winters, more abundant rainfall, and expanding crop production zones. But people in other areas will suffer from increased heat waves, coastal erosion, rising sea level, more erratic rainfall, and droughts.

The crops, natural vegetation, and domesticated and wild animals (including seafood) that sustain people in a given area may be unable to adapt to local or regional changes in climate. The ranges of diseases and insect pests that are limited by temperature may expand, if other environmental conditions are also favorable.

The problems seem especially obvious in cases where current societal trends appear to be on a “collision course” with predictions of global warming’s impacts:

at the same time that sea levels are rising, human population continues to grow most rapidly in flood-vulnerable, low-lying coastal zones;

places where famine and food insecurity are greatest in today’s world are not places where milder winters will boost crop or vegetation productivity, but instead, are places where rainfall will probably become less reliable, and crop productivity is expected to fall;

the countries most vulnerable to global warming’s most serious side effects are among the poorest and least able to pay for the medical and social services and technological solutions that will be needed to adapt to climate change.

In its summary report on the impacts of climate change, the Intergovernmental Panel on Climate Change stated, “Taken as a whole, the range of published evidence indicates that the net damage costs of climate change are likely to be significant and to increase over time.”

That is absolutely false. Do you have any idea how much a small change in temperature can do? According to nasa, "at the end of the last ice age, when the Northeast United States was covered by more than 3,000 feet of ice, average temperatures were only 5 to 9 degrees cooler than today." As the temperature continues to rise, more and more dramatic changes like this are going to occur. Making a claim like this without evidence is not making a legitimate point.
