Why is global warming caused by the enviroment? (i know it isnt but im in a debate)?

Question

i just need to know what the other side is going to debate about.

Answer 1

The opponents of global warming often cite the various fluctuations in the environment as evidence that global warming is simply another fluctuation. The problem with this line of reasoning is that the current warming trend in our environment has a rate of change that is far beyond anything in the history of the environment. For example we have had ice ages before and warming that melted the glaciers. Those warming trends took millions of years. The current trend is happening in the last 100 to 200 years - that is extremely fast compared to anything that has occurred in earth's geologic history. There in lies the difference.

Answer 2

Well they tell u that CO2 is the main problem ,they say it has increased 30% ,it has not if u don't believe go measure it . Well where did it go because the world produces millions of cubic ft of CO2.
If u remember back in high school when the teacher explained photosynthesis. Green plants in sun light absorber CO2 and give u back oxygen. Now u got that. If the CO2 is not there neither can u depend on anything they are saying,it is all garbage. For political reasons to reduce the fuel the US uses. CO2 is needed by the plants as bad as we need oxygen. There are many other parts that are just as stupid.

Answer 3

There is evidence that the Earth warmed up before and cooled off again. Some say global warming is a part of natual cycle, kind of like the reverse of the Ice Age.

Answer 4

There are many things we don't really know about:

The sun activity cycle, measured tempature data from pre 1800's, tempature measurements from the southern hemisphere.

Answer 5

Release of CO2 when trees are burnt.

Answer 6
