Okay posters on the USMB procaim their belief without any evidence and others are suppose to believe because they said so?
They probably still believe that the Earth is flat because someone says so
We know the world is warming because people have been recording daily high and low temperatures at thousands of weather stations worldwide, over land and ocean, for many decades and, in some locations, for more than a century. When different teams of climate scientists in different agencies (e.g., NOAA and NASA) and in other countries (e.g., the U.K.’s Hadley Centre) average these data together, they all find essentially the same result: Earth’s average surface temperature has risen by about 1.8°F (1.0°C) since 1880.
Scientist who study climate change disagree
The earth is warming. which does make sense
Why because years ago they had horse and buggies. They also did a lot of walking and sailing using the wind.
Today they got cars, trains, plane and nuclear weapons.
So who your going to believe?
There is overwhelming scientific evidence that Earth is warming and a preponderance of scientific evidence that human activities are the main cause.
