Dr. Richard Jones of the UK
Meteorological Office's
Hadley Centre gave a talk at the
Oxford Earth Summit entitled "
The science of climate change".
Quotes include: "A global surface temperature increase of 0.7°C has taken place over the past 100 years. Most of the increase has been due to human activities." "A 3°C increase (in global temperature) is likely by the end of this century (4x the last century)."
