"Natural sources of (CO2) include: volcanic eruptions, animal and plant respiration (breathing), decomposition of organic matter (dead plants and animals), forest fires, and the release of CO2 from the oceans (ocean outgassing), where it is naturally absorbed and stored; essentially, any natural process that breaks down carbon-based materials releases CO2 into the atmosphere."
Awesome copy-and-paste. Now please show me evidence of those processes increasing since the Industrial Revolution in concert with the rise in atmospheric carbon dioxide.
CDN is a channel on YouTube.
I checked out your Youtube channel which tells me that "The Climate Discussion Nexus offers a forum for more open debate on all aspects of climate change, especially better use of science to shape policy."
I watched several of the videos and looked at the titles/summaries of the rest. I didn't see any "open debate" but did see a lot of misinformation very similar to the sort you repeat here. The only "policy" I can see is the continued policy of funneling money to the fossil fuel industry.
Let's try something different:
- If I needed to land a plane, I'm sure you would recommend a pilot, perhaps even yourself.
- If I was having heart issues and shortness of breath, you would probably recommend I consult with a cardiologist.
- If my roof was leaking, you might suggest a general contractor or roofing professional.
We can agree that each of those individuals is an expert in their profession, but you hopefully wouldn't suggest that I ask a pilot about my heart issues or trust a roofer to land a plane with 300 passengers, correct?
So, now let's say I want to learn about climate science. Some might point me to the IPCC report as a synthesis of decades of research by hundreds of climate scientists. That's the very report I suggested you check out recently.
Your recommendation is instead that I start with a Youtube channel run by a historian/journalist. You might say, "Look, there's an interview with an 'exiled climatologist' on CDN, so that proves that climate change is a hoax."
You regularly insinuate that climate scientists are "on the take." Do you think that when a scientist is awarded a big research grant that money goes into their pocket? If that's your view of professional climate scientists, why would you believe that professional climate change deniers are any more honorable or honest?
It's great that you have advanced degrees. Me too. Probably lots of other folks around here as well. Mine are in Ecology/Evolutionary Biology, so I'm not an expert on climate science, but what I realized early on is that college and grad school are partially about gaining expertise in a specific field but more importantly about learning how to learn. Learning how to sift through evidence and data. Learning how to parse truth from fiction. Or, as my grandpa used to say, not letting someone piss on my leg and tell me it's raining.
Science grows through cycles of experiments (often modeling in this context), collection and analysis of data, more experiments/modeling, and so on. Over time, repeated research findings lend more and more support to certain conclusions (e.g., human-caused climate change, smoking is bad for you, gravity).
On the other side, you have Senator Inhofe from OK bringing a snowball into the US Congress during a Februrary (2015) snowstorm and waving it around as evidence of the climate change hoax.
These are not the same thing.
