Dr Joanne Simpson was the first woman in the world to earn a doctorate in meteorology. She has devoted her entire professional life to studying clouds and violent storms, and at 75, she’s still at it.
Formerly of the NASA Goddard Space Flight Center. Present Position Chief Scientist for Meteorology, Earth Sciences Directorate. Simpson’s career also included working with the Woods Hole Oceanographic Institution, and NASA. Former Colorado State Climatologist Roger Pielke Sr. Called Dr Simpson “among the most preeminent scientists of the last 100 years.”
The following are excerpts from her guest post on Roger Piellke Sr’s Climate Science weblog:
Since I am no longer affiliated with any organization nor receive any funding, I can speak quite frankly. […] The main basis of the claim that man’s release of greenhouse gases is the cause of the warming is based almost entirely upon climate models. We all know the frailty of models concerning the air-surface system. We only need to watch the weather forecasts. […] The term “global warming” itself is very vague. Where and what scales of response are measurable? One distinguished scientist has shown that many aspects of climate change are regional, some of the most harmful caused by changes in human land use. No one seems to have properly factored in population growth and land use, particularly in tropical and coastal areas. […] But as a scientist I remain skeptical. I decided to keep quiet in this controversy until I had a positive contribution to make. […] Both sides (of climate debate) are now hurling personal epithets at each other, a very bad development in Earth sciences.
