I'm not sure if climate change has been a human-caused issue or a nature caused or both. I've heard its human-caused, and I have even received proof with our co2 emissions. But I'm sure nature has something to do with it too...i'm just not sure exactly what...

Nature does affect it but naturally; carbon dioxide in the atmosphere changes, however, 97% of scientists agree that climate change is human-caused or anthropogenic. Nature does help the carbon dioxide though as well, seeing as plants "breathe" carbon dioxide.

oooh okay I get it now... a lot of the carbon dioxide is taken in by plants... so why would carbon emissions be a problem? are we creating too much carbon dioxide? or maybe carbon dioxide that isn't healthy for plants to take it?

Carbon dioxide is carbon dioxide. However, the plants can only take up so much carbon. This is why there is still so much in the atmosphere, and why the ocean has been becoming more acidic.

ooooooooooooooooooh I get it now!!!! so we have to find a way to limit our co2 emissions

Exactly!

so the letter that we have to write to a public official should state an idea of how we can lower those emissions...right?

Yep! And we can use ideas that we learned about so that we don't have to make it up if we don't want.

ooh like measuring how much we use or putting a limit on our emissions by law!

do you have Mr, Gundle?

Yeah! And yes I do.

ooh cool!

you live on queen anne...?

I think that the climate change is mostly human-caused, but I also believe that nature does have something to do with it.

I also think that climate change is primarily due to humans. The amount of carbon dioxide being put into the atmosphere has increased with our increase in population. I have also heard that global warming follows a natural cycle, is that true?

It does flow a natural cycle, such as during the ice age and middle ages, but nowhere near the speed where are pushing it to.

Yes, climate change has had it's ups and downs through the planets history, yet sense humans it has started to increase dramatically.  I think humans are the main reason that has increased some much in the past years.

The cool think about science is that there is evidence for all of us.  Yes, there are long term cycles that the Earth goes through in climate. But ask yourself:  Is there any precedent for the current rapid change in CO2 concentration and temperature rise?

Its both, this is because nature has its natural Co2 emissions we are just the ones to make more. As Mr.Gundle said the Co2 in the atmosphere is like a blanket that was originally just nature doing it, but we really just add more and more. Nature won't stop adding "blankets" but we can stop or at least not add as much. So in all Nature and humans both contribute to Co2 emissions but ours is the most impactful, Ours isn't natural unlike nature was supposed to do it.

Climate change is mostly humans who cause it but other things cause it too. For example, when volcanoes erupt they release a lot of particles and gases into the atmosphere. This creates a change in the climate.

Yes it is it's often due to the our dependency on fossil fuels but it can also be caused by volcanic eruptions or increased sun spots which cool the earth due to parts of the sun being cooler than other spots.

Yes, it is a fundamentally human caused problem, as the majority of extra co2 produced is the aftermath of human-caused actions, like the extended use of cars, the co2 produced by factories etc, also keep in mind that humans have cut a large amount of co2 "eating" plants and trees

The are useful references under "Climate Change Resources" in the discussion topics link. I particularly like the Union of Concerned Scientists " and the Climate Reality Project's Climate Science 101 and the film "An Inconvenient Truth"
