Aspects of his comment may be unwelcome to just about everyone in one way or another, but I think it is worth noting that he says that the data issues don't detract from clear evidence of a long - term warming trend and that carbon dioxide is «a major climate forcing» (along with many others):

1) On dry savannas in Africa the surface temperature of clear climate during daytime can reach about 50 C, but during nighttime can cool down until about zero C. However, CO2 content in atmosphere during all the time is the same, which proves that the carbon dioxide as greenhouse gas in atmosphere has no distinguishable influence on climate temperature.

Blackburn cited two climate scientists to make her point: One who has been «wrong about nearly every major climate argument he's made over the past two decades,» according to fellow environmental scientist Dana Nuccitelli, and another who recently said, «it's clear that adding more carbon dioxide to the atmosphere will warm the planet.»

In addition, Ridley did not make it clear that Myneni had suggested that 42 % of the 14 % increase in annual productivity «can be attributed to relaxation of climatic constraints to plant growth,» with «57 % to other «anthropogenic factors»,» whereas the paper published in the journal «Nature Climate Change» in April 2016 did not present a figure for annual productivity, instead concluding that 25 % to 50 % of the Earth's vegetated area had greened, with about 70 % of this trend attributable to carbon dioxide fertilization.
