Let me clarify my stance on all of this. Do I believe Climate change exists? YES. The climate has been changing on this planet since its creation. Do I believe that Carbon dioxide levels are directly responsible for the warming and cooling of the planet? NO! Carbon dioxide is a consequence of temperature, not a cause. Carbon dioxide is NOT a pollutant.
If the bold part were true tiga then the Earth would still be covered in a frozen layer of ice known as "Snowball Earth". A million years ago approx. it took volcanic eruptions to break through the ice and pump CO2 into the atmosphere. Without any carbon sinks due to the ice the greenhouse effect kicked in big time and eventually melted the ice. Once the rocky and watery Earth underneath (carbon sinks) were exposed the carbon sinks outweighed the sources and CO2 levels fell back down again. As an aside in the process O2 in the atmosphere rose from 1% to current levels of 21% leading to an explosion in macroscopic life.
From the Collins English dictionary:
pollution (n)
1. the act of polluting or the state of being polluted
2. (Life Sciences & Allied Applications / Environmental Science) harmful or poisonous substances introduced into an environment
The CO2 we are talking about is the CO2 produced as a waste product from the burning of fossil fuels to extract energy. This waste product CO2 which has a different carbon isotope ratio (13C/12C) to atmospheric CO2 is freely being pumped into the atmosphere as an addition to the CO2 already up there and has caused CO2 levels to rise from 280ppm to 390ppm in the past 150 years. We are pumping more CO2 (as well as methane (CH4) and other greenhouse gases) into the atmosphere than the natural carbon sinks can absorb so CO2 levels continue to rise. As it's leading towards a harmful situation on the environment (rising global surface temperatures over time (decades) and towards an extra 2 degree tipping point) then it's called "pollution" by definition.
Can anyone here prove to me that 1, the earth is currently warming and 2, that this warming is a direct consequence of increased carbon dioxide levels caused by humans in the earths atmosphere? I won't hold my breath on this one....
1. It's not a monotonic increase as shown for example in that paper posted by tiger101 just recently where layers of smog (SO2) can have a competing cooling effect that creates a temporary lull in the rise of surface temperature (see graph posted in this thread: post WWII - 1970s and 1999-2008) but the last two data points 2009 and 2010 have gone up again.
2. As mentioned above the ratio of 13C/12C carbon isotopes is different (slightly lower) in fossil fuels (as its made from mostly decayed plant material and plants prefer the lower atomic mass carbon 12 when they photosynthesize). So not only can scientists measure CO2 levels in the atmosphere but they also can measure the change in the isotope ratio in the atmosphere and this ratio has just so happened fallen over the past 150 years as we as humans have continually added CO2 with a lower ratio from the burning of fossil fuels.
The evidence for AGW is not based on modelling btw. It is based on various empirical evidence.
People, there is no boogie man in the closet! (No Ramps not Jim Boogie, he does exist )
You mean the coal industry and the economy in general ain't going to "die" due to carbon pricing as Abbott, McCrann and Bolt claim
.
And let's not to leave out the travelling Wizard of Oz with the phony peerage Chris Monckton who gives a few quotes in Latin as part of his act to give the impression he knows all yet when you remove the screen of BS he's just a con artist collecting money from gullible neo-cons who are desperate for someone anyone to tell them only what they want to hear. I mean if he's such a genius as his neo-con disciples claim then he should know the difference between surface area and volume when he's talking about Greenland
. Btw has he found the cure for AIDS and MS yet as he's claimed :nup. The guy is a complete and utter nutjob! He reminds me of emails out of the blue telling me Einstein's theory of general relativity and quantum physics were totally wrong and how their BS "theories" that actually prove nothing were right. It's quite amazing that there are fruitcakes out there who fanatically believe their mumbo jumbo pseudo-science crap and think it's a conspiracy theory when no one in science takes them seriously!
