Scientists are not being ambiguous when they say that Climate Change (or “global warming” if you will) is being caused by man. That the current crisis is indeed a man-made disaster is the general consensus among up to 97% of the scientific community, as opposed to a mere 3% who dispute it. If it hadn’t been made into such a political issue, the scientific consensus on Climate Change would’ve been enough to shut off further debate.
Humans are solely responsible for Climate Change in the world today. The IPCC or Intergovernmental Panel on Climate Change revealed that there is a “global scientific consensus that human action was indeed affecting global climate patterns”. (W. M. Adams, Green Development, p.17, 3rd ed, New York).

“Most climate scientists agree the main cause of the current global warming trend is human expansion of the “greenhouse effect”1 — warming that results when the atmosphere traps heat radiating from Earth toward space.
Certain gases in the atmosphere block heat from escaping. Long-lived gases that remain semi-permanently in the atmosphere and do not respond physically or chemically to changes in temperature are described as “forcing” climate change. Gases, such as water vapor, which respond physically or chemically to changes in temperature are seen as “feedbacks.”
