Why you cannot research your own answers to your questions is beyond me. Do you know what it is? Research? If so, why don’t you do it, yourself?
You made a claim, and i am questioning it. Are you not responsible for defending your own assertions or am i supposed to do the work for you? Are we going to discuss the topic or simply take jabs at each other?
This is YOUR data.
No, it isnt. I did not compile the data, nor did i link it. So far ive been mostly unquestioning YOUR data....
Btw, do i need to provide citations for questions as well? Please defend YOUR own claims. Are you always this aggressive in your debates?
However, since 1981, we’ve been using the arbitrary period of 1981 – 2020 as the 30-year-period with which to establish a baseline climate model of temperature, greenhouse gasses, sea level, etc. Why that particular 30-year period?
Probably cause its the most recent 30 years? What 30 year period do you prefer? Are you saying there is no data showing warming before 1980? From your 3rd link, 1st paragraph:
"The Global Historical Climatology Network–monthly (GHCNm) dataset is a set of monthly climate summaries from thousands of weather stations around the world. The monthly data have periods of record that vary by station with the earliest observations dating to the *18th century*."
Im sure you will question the data from the 18th century, i would too, but i dont think anyone is only looking at the last 30 years.
Re: margin of error
Yes that is a huge margin of error, although its about as big as your 140 mil claim which was actually 80-140mil, aka 110 +/- 30, a margin of error of slightly over 25%.
Either way, the uncertainty does not negate the trend. The lowest possible value in the 2010s is higher than the highest value at any time before 1990. The trend is undeniably and consistently warmer. What could have caused this?
Also, you dodged by specific questions:
"1. Do you agree co2 is a greenhouse gas?
2. Do you agree man releases substantial amounts of co2 in industry, transportation, etc?
If the answer to both is yes, man' contribution to climate change is undeniable."
Please answer.
you completely ignore the most obvious animal to adapt to just such wide extremes as desert to polar environments: man.
Lol. Drop a man without tools, or clothes in a desert or arctic and 99% will die. We did not adapt to those climate via evolution, we adapted to them using technology. I thought you were comparing climate to darwin, not ford. Man evolved in the savanagh, that is where we naturally thrive. We did not evolve for any other environment. We lost the ability to effectively climb and swing through jungle trees. We do not retain water well enough for the desert. We do not maintain heat well enough for the arctic. And as for the urban jungle, we adapted that to us, not the other way around. What we were adapted for is long distance running in a savanagh, the climate of a savanagh, and the pack hunting that is most effective in an open savanagh. We didnt adapt white skin for the european sun while still in africa, we adapted to the European environment after we moved into the european environment. What you are saying makes absolutely zero sense.
