ORIGINAL: jlf1961 Hmm, humans are the only thing responsible for climate change.... Solar Variability and Terrestrial Climate and then Sun's Activity Increased in Past Century, Study Confirms So while climate change is happening, the guilty party may not be humans.... Oh shit, the liberals are going to blame industrialization as the reason for increased solar activity. No, increases in solar activity mean nothing as the AAT (average atmospheric temp.) has gone up and down regardless. The link on post 29 In all of my study over the years, I have never even once read or heard anyone proclaim that man is solely responsible. However, almost every scientist on this issue has proclaimed that the countless billions of tons of CO2 entering the atmosphere since the 1880 or so, has been the single biggest influence in adding CO2 and thus increases its greenhouse effect. Okay, so every instance that the earth's atmospheric CO2 levels have been this high or in some cases higher, has been the direct result of humans burning fossil fuels? Even a million years ago? However, the term 'single biggest influence in adding CO2' kind of points to humans as being the single biggest influence, would you not agree? Unless there are other species burning fossil fuels I am not aware of? Which goes back to humans are to blame for climate change. Lets look at some alternatives to fossil fuels.... Solar power, well to power even a small city, you are going to need a thousand acres of solar panels. Wind farms, great idea, except that each wind turbine takes two acres out of potential agricultural production, which is the argument against using grain crops for ethanol production, we need that to eat.... Geothermal, hey this is a great idea, using the earth's natural super heated water to power turbines and generate electricity, except that there is a bit of a sulfur smell coming off the plants and even tree huggers protest that as unacceptable. Hydroelectric, got a couple of choices with this one, build one massive damn or a series of small damns, the tree huggers complain about both because it impacts the rivers, and fish, and well..... Funny thing is that these people screaming about the different forms of electricity generation are using electricity.... Well now, again, no, never said man was solely responsible. However, it is the major influence in adding CO2 which..... Human CO2 emissions upset the natural balance of the carbon cycle. Man-made CO2 in the atmosphere has increased by a third since the pre-industrial era, (33% more since about 1880) creating an artificial forcing of global temperatures which is warming the planet. While fossil-fuel derived CO2 is a very small component of the global carbon cycle, the extra CO2 is cumulative because the natural carbon exchange cannot absorb all the additional CO2. The level of atmospheric CO2 is building up, the additional CO2 is being produced by burning fossil fuels, and that build up is accelerating. Note: Although our output of 29 gigatons of CO2 is tiny compared to the 750 gigatons moving through the carbon cycle each year, it adds up because the land and ocean cannot absorb all of the extra CO2. About 40% of this additional CO2 is absorbed. (60% of man made CO2 is not absorbed) and rest remains in the atmosphere, and as a consequence, atmospheric CO2 is at its highest level in 15 to 20 million years (Tripati 2009). (A natural change of 100ppm normally takes 5,000 to 20,000 years. The recent increase of 100ppm has taken just 120 years). (that takes back 1897) HERE
