Scientists increasingly refute global warning as a man-made climate change and argue that climate has been undergoing change for millions of years. Many believe that what we call a planetary death spiral, warmageddon, or climate change is nonsense or simply a myth.
The Global Warming Theory
Climate change refers to transforming weather patterns that result in cooling or warming as a result of the changing balance between the outgoing and incoming energy. Global warming, on the other hand, is the result of human activity and greenhouse gas emissions released into the atmosphere. Evidence in support of global warming is based on changes in vegetation, melting glaciers and rising ocean levels, and more frequent extreme weather and natural disasters such as floods, droughts, wildfires, heatwaves, and hurricanes.
Former UN IPCC Director Robert Watson warns that 4-degree warming would result in permanent drought across Europe while large areas of Bangladesh, India, and China would turn into deserts. Warming of 5 degrees would mark the end of humankind and civilization. Humans are to blame for this because burning gas, oil, and coal releases huge quantities of greenhouse gas emissions into the atmosphere. And the larger the amount, the more serious the impact and the warmer the climate.
How Scientists Explain Climate Change
Contrary to the opinion of researchers at the Intergovernmental Panel on Climate Change, carbon dioxide does not have the impact that has been projected. Additional carbon dioxide had more effect 100 years ago than it has today. The reason is that higher carbon dioxide levels result in the formation of more eukaryotic phytoplankton which removes CO2 from the seas and oceans. University of Manchester professor Leslie Woodcock also argues against climate change by noting that the change in greenhouse gas emission levels is not significant compared to 100 years ago. In fact, carbon dioxide makes for just 0.04 percent of the atmosphere while water, which is also a greenhouse gas, is about 1 percent. Richard Lindzen, a professor and atmospheric physicist, claims that warming has ended almost two decades ago. In a lecture delivered at the Global Warming Policy Foundation, professor Richard Lindzen called the theory of global warming a nonsense. In his view, mean temperatures have not changed significantly on a global scale and not to the extent that computer models have projected. To this end, critics point to the fact that the assessment methodology of IPCC is deeply flawed and requires considerable improvements. The InterAcademy Council, a major scientific network in the U.S., came to a conclusion that the statements contained in the reports were based on little scientific evidence. In fact, some even go as far as to argue that the panel is a political think tank and a pressure group and the global warming agenda is political rather than scientific.
Georgia Tech University professor Judith Curry also argues that the computer models used are not reliable in predicting climate change. During the period from 1997 to 2012, global mean temperatures have not changed significantly. The last period of rising temperatures has been about the same in length as the previous one when temperatures rose for 16 years between 1980 and 1996. Temperatures declined or remained stable for 4 decades before 1980. Professor Judith Curry explains that despite the complexity of computer-based climate models, there are other factors that play a role, including the sun’s energy output and the ocean water’s temperature cycles. Such factors may contribute to global warming more than human activity. Climate Research Unit director Phil Jones shares the opinion that computer models are flawed and fail to account for variation in climate parameters. The impact of changes in oceans on global warming, for example, has not been fully assessed. What is more, natural variability may be the major factor why global mean temperatures did not rise significantly over the past 16 years.
