The Great Global Warming Hoax was the most watched documentary and critical of the scientific consensus that climate change is due to anthropogenic activities. Broadcast in 2007 in the United Kingdom, the documentary purported to debunk the “myth” of man-made global climate change, exposing it as a vast conspiracy designed to obtain research funding and promote an environmental agenda particularly harmful to the developing world. of development. Directed by British producer Martin Durkin, the documentary includes discussions with a number of scientists who are skeptical of man-made global warming and argue that their views are being deliberately censored in favor of the politically correct consensus. While critical of global warming alarmism, this documentary leaves no doubt that the earth is warming. They argue instead that scientific evidence shows that such warming is nothing more than a natural variation in the earth's climate history, similar to the medieval warm period of the Little Ice Age. The documentary uses several lines of evidence to support this claim, including ice core data which they say, if interpreted correctly, shows that carbon dioxide has a lag time when Earth's climate has warmed in the recent past and far away, making it doubtful that it could be responsible for the recently observed temperature rise. The timing of recent warming is analyzed, which was most pronounced from the late 19th century until World War II, stopped and reversed to a cooling trend in the mid-20th century, and then rapidly warmed again over the past three decades . Given that this warming began before the advent of major human sources of greenhouse gas emissions and the period of most dramatic industrial warming… middle of paper… global warming? Well, it's warmer.
