Carbon dioxide levels in the atmosphere are on the rise. That's one thing even the climate change skeptics can't challenge.
And most climate experts agree that CO2 emissions from humans is increasing Earth's overall temperatures at a faster rate than at any other time in recorded history.
However, there are some people out there — even scientists — who question whether Earth will, in fact, warm up over the next 100 years and how it will effect Earth's overall climate and ecosystems.
Here are some of the scientists who have gone on record with their controversial views:

Craig Idso is founder and former president of the Center for the Study of Carbon Dioxide and Global Change, which is a non-profit organization that publishes the newsletter CO2Science, which sharply disputes scientific opinion on climate change.
Last year, a recurring face at the annual International Conference on Climate Change, Craig Idso said "There is no dangerous human influence on Earth's climate from a rise in CO2."
Idso asserts that rising CO2 and resulting warmer temperatures will not only greatly benefit plant growth but will also reduce the risk of cardiovascular deaths in humans, as well as other spectacular claims.
His presentation, which you can watch here, is overwhelmingly positive, choosing to focus on the plants and animals that will thrive from raising CO2 and completely neglecting those that could go extinct, or the islands that will disappear, or the damage done by flooding coast lines.
Patrick Moore is the former president of Greenpeace Canada, a non-governmental environmental organization that focuses its campaigns on climate change, deforestation, overfishing, and other worldwide issues.
Earlier this year Patrick Moore told Energy Live News"I am firmly of the belief that the future will show that this whole hysteria over climate change was a complete fabrication."
According to Greenpeace, Moore "exploits long-lost ties" with the organization to sell his anti-environmental opinions on carbon dioxide. Moore thinks that this greenhouse gas is in no way related to global warming and that it's a "good thing" that we're putting more into the atmosphere. He's forgetting the overwhelming evidence to the contrary.
Anastasios Tsonis is a distinguished professor of atmospheric science at the University of Wisconsin-Milwaukee whose research is widely touted by climate-change-denial outlets like Climate Depot.
Anastasios Tsonis has said he's not a climate change denier, but he also is of the belief that Earth is not necessarily getting any warmer. Tsonis is part of a group of scientists who think that Earth's climate flips between a "warm mode" and "cool mode" every 20 to 30 years, driven by oceanic temperatures, particularly the Atlantic Multidecadal Oscillation (AMO) current.
Right now we're in a "cool mode,"he told British journalist David Rose in 2010. "We have such a change now and can therefore expect 20 or 30 years of cooler temperatures." While the AMO is a confirmed natural phenomenon, there is controversy as to its periodic changes and influence on climate.
