Scientists explain global warming consensus

Joseph Henry LaCasce... "Naysayers are playing devil’s advocate or not qualified to discuss the science."

The atmospheric C02 levels have been rising alarmingly fast since the early to mid-20th century, and the global mean surface temperature has been rising in tandem. There is no serious disagreement about these trends, because both C02 and temperature can be measured with high accuracy.

He goes on to say that the C02 increase is due to anthropogenic forcing, i.e., it is human-induced, and that climate models are now sufficiently reliable to differentiate between the warming caused by CO2 as oposed to other natural factors.
