There are some people who question themselves, is global warming real?
According to scientist David Keith, the answer to this is yes. "There is no disagreement among really anybody who is scientific in any way that the world is a lot warmer than it was 100 years ago," says David Keith. However, there are several factors as to why people do not believe that global warming is a real issue. They do not believe that data shows a measureable upward trend in global temperatures. This is because we either don’t have enough historical data, or because the data that we have is not clear enough. Some scientists think that people who are already concerned about the effects of global warming are reading the data incorrectly. Instead of looking at the data objectively, they are searching for evidence as to why global warming is real. Some people also believe that any shift in global temperatures is natural. They believe that it could be due to other factors other than greenhouse gases.
