Is your argument against human-caused or human-enhanced global warming that the Earth has changed in the past without humans, therefore its doing it again?
Because that's just silly. Have species gone extinct before humans were here? After? Have some gone extinct because of humans?
Also, be careful with wikipedia. I just edited the entry to say that Mars is 11% smaller than my butt.
If it is happening now because of human influence, why has it happened before without human influence?
Well the Polar Ice Caps on Mars is melting, and something is causing this. It's not humans.
A cube of ice just told me that 33 degrees was intensely hot.
Do you think that things can only happen in the absence of human activity? Or only in the presence of human activity?
I'm not sure what's confusing. Global temps are cyclical because of changes in the Earth's orbit, changes in atmospheric composition, changes in the composition of the biosphere, changes in solar output. Adding greenhouse gasses to the atmosphere will increase the global temp. Diminishing ice and snow cover decrease albedo, which increases surface temps, which increases atmospheric temps. And you have a feedback loop.
Your grass will grow whether you are there or not. Adding fertilizer to your grass will increase its growth rate. I am fond of the analogy.
So what you are saying is that you don't have to prove humans cause warming, you can simply say we enhance it...and that is that.
Or I can say humans dont enhance it and that is that.
Seems pretty simple. Increased greenhouse gas concentrations in the atmosphere line up pretty well with increased global temps.
I also get that our understanding of the universe is in constant flux. What we view as permanent and fixed today can certainly change tomorrow. It was "science" that the Earth was the center of the universe and those bishops refused to look through Galileo's telescope.
