ok.if you want to do an experiment at home to see about carbon vs temperature.
here is a simple one
get 5 small empty drinks bottles
fill them as such
4/4 plain water
1/4 plain water 3/4 sparkling water
2/4 plain water 2/4 sparkling water
3/4 plain water 1/4 sparkling water
4/4 sparkling water
mark the bottles to know which is which
ok now you have an experiment. of 5 differing levels of water vs carbonated water.
now put them all into a freezer at same time and every hour check on them.
note if there is any difference between freeze rate.
this is to find out if the amount of carbon helps or hinders freezing
.
then when all frozen. take them all out and put the somewhere in the same ambient area and watch the periodically to melt and see which one melts the fastest
then YOU will know for your own sake and own observation the real affect of carbon dioxide on temperature
it would only cost you probably the cost of 2 sparkling water bottles. so not even $1.

as for vegetation
well thats study is flawed... not in is common sense that plants grow.. but the fact that it says 'compared to xx time in past'
simply because 100 years ago they didnt have satelites to map the greenary.
also new hybrid plants that offer better crop yields have been purposefully made to allow for more then 10% growth. and that has nothing to do with carbon but selective breeding for mass production
..
so although the common sense that carbon helps plant growth is true. his lack of utility of finding actual study to back him up makes the common sense sound less common sense.
again another home experiment.
have 5 plants. in plant pots
trim off the bottom of 5 large soda bottles to make plastic domes over the plant pot. seal them. then put smoke at varying amounts into each. and then watch them grow. .. that would be more of a valid study
..
but with all that said. carbon is a negative for lung health. its also a finite supply thats near run out so financially yes they have to shift even if there was no health impact.
but when it comes to the climate change. the water cycle affects temperatures more then carbon
