She is right in stating the causation of climate change not being proven one way or another. Interesting SA had an article 'Predatory journals publish dubious work' yesterday that points to scholarly maleficence. There are many weak points in the global warming alarmists postulation/projections (i.e. CO2 and  air temperature are not connected as much as water vapor and air temperature are), and thankfully to date, most of those dire predictions have NOT come true. It is simply not a settled science or, our TV weathermen would be right more than 20% of the time. The earth's temperature is rising and our oceans are by far the biggest contributor to global CO2 and water vapor. On that we all agree, the rest is accepted by your worldview...
Again, she was right.
