We have shown that the biosphere is indeed changing, due to a climate change that most likely is a direct consequence of human activities (principally in the industrialized countries).
There is absolutely no evidence in the article as posted that the change is "most likely" a direct consequence of human activites in the industrialized countries. This is pure propaganda/unfounded speculation. There is no discussion of possible causes; just a remarkable leap to pin the blame on humans activity in "industrialized countries."
The biosphere is in a constant state of change and the possible causes are many and varied. The article ignores mountains of real evidence that biosphere change is caused by long-term natural processes unrelated to human activity. The work of these computer modelers cries for objective peer review as well.
Your statement above is entirely correct. The implication of human activities comes from other sources.
