Global warming = something being measured
Man made global warming = being debated.
Human link to global warming = being debated (my park)
Scientists of many countries from many fields as well as craftsmen who have come to the conclusion that the climate is gradually warming (ask any farmer, weatherman, carpenter, biologist, oceanologist, botanist or Fisherman up here) are not being paid to cling onto that specific opinion.
Scientists are however being paid by the oil companies to hold forth that specific opinion.
The government sponsored scientists BTW, have no special interest in having that special conclusion, - they can get their sponsors with any conclusion so to speak, - and they do indeed get discovered in both camps.
Capiche? Or too complicated.
(I sure aint getting paid, just wasting my time here. Maybe I should learn about philosophy, join the flat earth society, and apply for the counterjob at Exxon's HQ)
