A new report outlining the effects and contributing factors to global warming is due out Friday.
"We've had a very rapid rise in temperatures the past 30 years," said Dr. Gerald North of the Texas A&M Department of Atmospheric Sciences.
Leading scientists are expected to name humans as the main cause, and some climatologists at A&M couldn't agree more.
"Most likely humans are the cause of the warming because of our greenhouse gas emissions," said North.
Some of the effects of global warming can already be seen locally.
"Particularly, Winter and Spring the past few years have started to go above the range of temperatures that we've observed historically," said Dr.John Nielsen-Gammon, professor of meteorology at Texas A&M, and a Texas state climatologist. "So we're starting to see some impacts at the local level."
According to scientists, now more than ever, people need to be aware of their impact towards global warming.
"There are some things we could do, even if we turn out to be wrong about it, it wouldn't hurt," said North. "For example measures of efficiency, and automobiles, building, heating, things like that."
"The change is going to be upward no matter what," said Nielsen-Gammon. "The only question is how much."
