After some individual observations that individual high temperature years such as 1998, caused by the natural el nino, corresponded with years with higher annual rises of CO2, someone decided to plot them all. Every temperature peak is followed by a peak in CO2. It's funny how no one else appears to have noticed this very simple relationship but would be interested to hear anyone's explanations when they do see it. Ole Humlum scores again
This has been explained by the Reading University's Bill Collins:
“There has been a big deal made of this being the second highest annual rise ever – but there is quite a lot of variability in CO2, due to plant ecosystems, so the last highest rise was after a very warm year.
“That was 1998 and not basically due to man-made causes but because it had been a hot year and the soils had given off a lot of CO2 and the plants had not grown strongly – so the year to year variability is often caused by the uptake of plants and trees."
It's quite hard to argue with that, and if it applies to 1998 and can be seen in all the other years, along with the given reasons, then why are we still being blamed for it? Whole article
