This expert happens to be THE preeminent mind in the meteorological community when it comes to hurricanes. and, imperfections aside, he KNOWS ocean currents and such. If he says ocean currents are a factor in a warming Earth, bank on the fact that they, indeed, are. In your haste to bash GW, do NOT overlook the fact that Dr. Gray is NOT, in fact, voicing support for it being caused by humans; that he is on the same side of this debate as you are.
Do make an effort NOT to cause a “friendly fire” incident, here.
Obviously, if you askd Dr. Gray about the mechanisms influencing warming on Mars, he’s not going to blame currents in the freakin’ Pacific.
The Earth has been warming since the end of the last ice age. Next issue
We all know the cause of global warming on Mars is the recent introduction of two SUVs to the planet.
