Based upon research climate change data does show that there seems to be a strong correlation between greenhouse gases being emitted by humans and climate change. Historical data obtained from the Vostok ice cores, which goes back over 600,000 years, shows that changes in CO2 is followed very closely by temperature. Side: Yes
Strong correlations are not good science. This happened, then that happened, so this must have caused that. Hmmmm. Cause and effect logic is a lot more stringent than that. The evidence is clear that carbon levels have risen and fallen in the past, when we were not even here yet. Nature has brought about many ice ages without a single gallon of gas having been burned. Forty years ago we were told that an ice age was eminent. Thirty years ago we were told that the Ozone layer was thinning because of hair spray. Twenty years ago we were told that the globe was warming and the polar ice would melt and the oceans would rise. Absolutely none of that came to pass. The Ozone layer was shown to be effected not by hair spray but natural variations in the planets magnetic field. The polar ice is increasing in thickness while Al Gore has been preaching the doom of us all. Side: No
The evidence is clear that carbon levels have risen and fallen in the past, when we were not even here yet. Fire happened before before we were here, does that mean we cannot be responsible for fires now? It is because of the past changes we can look at todays and compare. Just because some of the source of the green house gasses is caused human activity why would that change the properties of the gasses? For examples of greenhouse gasses changing the climate check out the permean triassic period. Forty years ago we were told that an ice age was eminent. A paper that was sensationalized by the media told us this, there was no concensus among scientists across the globe. Poor comparison. Twenty years ago we were told that the globe was warming and the polar ice would melt and the oceans would rise. Well then predictions confirmed, the oceans have and are rising. Side: Yes

The evidence is clear that carbon levels have risen and fallen in the past, when we were not even here yet. Which obviously says nothing whatsoever about whether humans CAN have an effect once we arrived. The previous fluctuations in global temp may have been "natural", but they each had specific causes. Continental drift, long term milankovich cycles and volcanic activity all have this ability, but none appear to be the culprit for the measured increase of the last century. SOMETHING causes these changes, and until human activity can be decisively ruled out, or another completely independent source can be identified, human activity should still be on the table. Forty years ago we were told that an ice age was eminent. By news casters, NOT the majority of climate scientists. Something tells me you still get your climate information from reporters, which seems a little silly don't you think. Journalists don't need to master physics or the technology that climate experts do. The polar ice is increasing in thickness No, globally we are still loosing ice. Just because seasonal variations regrow a little sea ice or thicken the occasional ice berg, this does not invalidate the overall trend. Permafrost is melting too, by the by. Side: Yes

The ozone layer problem has been solved by a worldwide regulation on specific chemicals. The scientists who worked on that problem are now trying to figure out how to solve the climate change issue. So this just shows what we can do if we act on climate change, but drastic action is needed. http://acdb-ext.gsfc.nasa.gov/Documents/ Side: Yes

Yes. Every human breathing out Carbon Dioxide and farting methane is having a serious impact on the climate. They must immediately stop their breathing and farting, or else the world will end. Failing their voluntary action of simply keeling over dead, they must pay an immense carbon tax to strongly encourage them to reduce their natural but harmful emissions of Greenhouse gasses. And after they die, their bodies must be catapulted into space (with carbon-neutral wooden catapults), forever frozen in ice (via a carbon neutral process of traveling to the arctic regions), or their children taxed again on carbon credits, since burning and natural decomposition would permit additional greenhouse emissions to destroy the delicate climate temperature balance earth has maintained for eons before humankind started its climate destruction of breathing and farting and decomposing. Right? Well, at least the government will get a bunch of tax money to spend on green projects like planting trees, growing algae, and metal-less woodworking. Side: Yes

Where is your specific evidence to support that this is just part of the natural cycle? If you look at the Vostok ice core data you will see that while there is a cyclical effect, the amount of carbon still increases and decreases with temperature. Check out data on my link! Side: Yes

If you people do not understand that the Democrat party constantly uses normal events to further their agendas. Case in point, they use tragedies in school shootings to try & ban our right's to guns. They use every hurricane or polar vortex or who knows what to force their environmental agendas. Where are all those hurricanes we were going to start having? The hurricanes have gone WAY DOWN since their global warming crusade. The global temperatures have not risen in 18 years! They are truly dishonest(as we saw with Obamacare) corrupt politicians who will destroy this nation with debt & taxes all to pass their fanatical control over the people. Side: No
