Global Warming, Yes or No?

Scientist who support and oppose theories of Global Warming.

Scientist Who Believe in Global Warming

Naomi Oreske

Background:
Naomi Oreskes is an American Historian of Science. She is a Professor of the History of Science and Affiliated Professor of Earth and Planetary Sciences at Harvard University. She started this position in 2013, after 15 years of being a Professor of History and Science Studies at the University of California, San Diego.

Global Warming:
In her 2004 paper published in Science, "Beyond the Ivory Tower: The Scientific Consensus on Climate Change,” she analyzed about 1,000 scientific journals to directly assess the magnitude of scientific consensus around climate change. She also found that 75 percent of published studies supported global warming as well. She is a strong believer when it comes to protecting the world from harmful toxins. She believes that the day-to-day interactions humans have with the environment can cause unnatural effects in the atmosphere.

Richard Tol

Background:
Robert Tol has a Masters Degree of Science in Econometrics and Operations Research. He also has a PhD in Economics as well. He is also a Professor of Economics at the University of Sussex. Lastly, he is a Professor of the Economics of Climate Change at the Vrije Universiteit Amsterdam.

Global Warming:
Tol believes in Global Warming like Oreskes, but has different views about it. He believes that Global Warming is not a man-made crisis. Tol also thinks that climate change and Global Warming will not lead to conflict between people because it is an idea that is understood between majority of people. He also believes that humans can do something to help the environment with Global Warming. One of Tol's "favorite" ways to prevent further Global Warming is by taxing the people on fossil fuels that may contribute to the problems of Global Warming. He believes this will lead to less use of fossil fuels.

Scientist Who Do Not Believe in Global Warming

David Bellamy

Background:
David Bellamy studied at the faculty of Biological Sciences: Zoology, Botany, Physics and "Chemistry in the sixth form." After he left school he worked as a laboratory assistant at Ewell Technical College before studying for an Honors degree in Botany at Chelsea College of Science and Technology.Then in 1960 he became a lecturer in the Botany department of Durham University. He is an English author, broadcaster, environmental campaigner and botanist.

Global Warming:
Bellamy once believed that Global Warming was a true phenomena, but not anymore. In 2004, he wrote an article in the Daily Mail in which he described the theory of "man-made" global warming as "poppycock". He also published a letter on April 16th 2005, in New Scientist saying that a large percentage (555 of 625) of the glaciers being observed by the World Glacier Monitoring Service were advancing, not retreating. However, since that statement, he has retreated from the "debate of Global Warming" due to the many controversies of his statement, and unidentified background research. However, more of his work and beliefs were still published. In June 2007, The New Zealand Centre for Policy Research published an opinion piece by Bellamy stating amongst other things that "There are no facts linking the concentration of atmospheric carbon dioxide with imminent catastrophic global warming." This showed that he still stands my his opinion on Global Warming, and believes that it is not a real problem in our current world.

Craig Loehle

Background:
Craig Loehle worked as a research ecologist at Savannah River Laboratory from 1987 to 1991, and in the environmental research division at Argonne National Laboratory from 1991 to 1998.While at Argonne, he conducted research which found that trees can grow to maturity up to a thousand miles south of their natural ranges, but only fifty to a hundred miles north of their natural ranges. Along with that discovery, he has found many other discoveries. He is currently working as an American ecologist, as the chief scientist at the National Council for Air and Stream Improvement.

Global Warming:
Loehle does not believe in Global Warming, and actually believes that opposite effects will happen on the environment instead of the green house effect. In 2004, Loehle published a study which concluded that "global and northern hemisphere temperature will drop on century scale in the next 20 years." So far, Loehle's predictions are correct. The Earth's temperature in general have been "record-level colds." He also believes the reason many of the "negative" events happening on Earth are due to human interactions. In 2012, Loehle said that while many animal species have gone extinct in recent years, that this was not caused by global warming but rather by humans hunting them and introducing pests and diseases.
