Consider yourself lucky to still have enough hair to wring out.
Yeah, global warming will render us all hairless soon.
Of course climate change is happening, just as it has for the last billion years or so. While humans are contributing in some way or other, and destroying vast tracts of forest that would otherwise contain CO2 certainly ain't helping, [b]nobody yet has managed to work out the mechanism that causes general global cooling and heating.[/b]
I once worked it out and it is roughly 12 billion trees per annum if you assume [ very generous ] that each tree absorbs 1 tonne per year so tree planting is not a solution
Re the enboldened bit we have but we do not understand every last detail - there is no branch of science where we understand every last detail or science would have stopped. It is not accurate to say we have not worked it out - its not complicated- big firey ball in the sky provides heat, greenhouse gases trap some of the heat [ infrared radiation] or stop it leaving to keep us warm - increases and decreases will have effects.
We have know about the greenhouse effect since 1832 and we know that increasing the amount of C02 means the earth stores more energy [ heat] - we can even tell you what this value is. To argue we wont warm up is like arguing if you put an extra log on the fire the room wont warm up.
The difficulty comes in the fact that it is an immensely complicated systems with [ some limited] checks and balances that will maintain homeostasis. However , if we displace this balance by say doubling the amount of CO2 by burning of fossil fuels [ stored carbon] we know it will have an effect, the only question is what. Given it is a greenhouse gas its not hard to work out what will happen. If you wish to argue we don’t know what will happen you would need to propose some method whereby the stored energy [ heat] does not warm the planet.
Let's face it, humans didn't cause the last five known ice ages or the warming that ended them. The most likely candidate, that seems to make most sense, is variations in solar output; after all, Sol is a known variable star.
As GrahamsS notes that is just not true not least because the suns output has been dropping of late and temp rising...you may wish to look up the Milankovitch cycle to explain how the suns output [ more accurately our proximity to it] has impacted on temperature
[b]No one is arguing there has never been natural change but because there has been natural change it does not follow that all change must be natural or that we could not change the climate by our actions[/b].
I assume the poster will concede the industrial revolution and our reliance on coal, gas and oil are not "natural but man made , they release Co2 and it is a greenhouse gas.
Suns just come out down here. Panic over everyone. As you were.
