Global Warming ; A Contrary View
Published on 1 Jul 2013
Dr. Tim Ball, the head of the National Resources Stewardship Project in Canada, shared his views on global warming. Many different types of climate cycles, specifically those related to the sun, can cause warming trends, he suggested. The increase in C02 emissions is overemphasized as a factor in warming, he argued, and the science in the film An Inconvenient Truth is based on faulty computer models.
Dr. Tim Ball is a renowned environmental consultant and former professor of climatology at the University of Winnipeg. He has served on many local and national committees and as Chair of Provincial boards on water management, environmental issues and sustainable development. Dr. Ball's extensive science background in climatology, especially the reconstruction of past climates and the impact of climate change on human history and the human condition, make him the ideal head of NRSP (National Resources Stewardship Project). His other work in such areas as water resources, sustainable development, pollution prevention, environmental regulations, the impact of government policy on business and economics will be invaluable as NRSP tackles other issues starting later in 2007.
The global warming controversy refers to a variety of disputes, significantly more pronounced in the popular media than in the scientific literature, regarding the nature, causes, and consequences of global warming. The disputed issues include the causes of increased global average air temperature, especially since the mid-20th century, whether this warming trend is unprecedented or within normal climatic variations, whether humankind has contributed significantly to it, and whether the increase is wholly or partially an artifact of poor measurements. Additional disputes concern estimates of climate sensitivity, predictions of additional warming, and what the consequences of global warming will be.
In the scientific literature, there is a strong consensus that global surface temperatures have increased in recent decades and that the trend is caused mainly by human-induced emissions of greenhouse gases. No scientific body of national or international standing disagrees with this view, though a few organisations hold non-committal positions.
From 1990--1997 in the United States, conservative think tanks mobilized to undermine the legitimacy of global warming as a social problem. They challenged the scientific evidence; argued that global warming will have benefits; and asserted that proposed solutions would do more harm than good.
