here you go. took a while to find this.
Paul Epstein, associate director of the Center for Health and the Global Environment at Harvard Medical School, in an email interview:
"The most coherent explanation is that climate is changing because of burning of fossil fuels and felling forests. The health, environmental, and economic costs of inaction are rapidly becoming unmanageable. Stabilizing the climate will require a clean energy transition that will also benefit public health, improve energy security, and can become the engine of economic growth for this 21st century.
"We're seeing changes in asthma, heat wave deaths, and the spread of infectious diseases that are indicative of enormous changes affecting the environment. Climate and disease are stalking humans, wildlife, agriculture, forests, and marine habitat; which are our life support systems."
i see nothing in there about natural warming trends or cooling trends, only about polution causing global warming and diseases.

Kurt M. Cuffey, professor of geography at the University of California in Berkeley, in an editorial for The San Francisco Chronicle in 2005.
"When we look at the complex environmental systems of our planet, from climate to the polar ice sheets, there will always be lingering uncertainties, and some surprises probably await us. But in the thorough and convincing rebuttal of the last contrary arguments, we have just witnessed a historically important validation of the scientific evidence for human causation of climate warming. And Katrina and the waning polar ice caps remind us how important this is.
"It is time for remaining skeptics to look at the tear-streaked faces of refugees from New Orleans, as well as the startling map of ice shrinkage around the North Pole, and begin to plan for the future."
again they claim only man has cause the global warming.
