"We are sliding back into a dark era," she said. "And there seems little we can do about it. I am profoundly depressed at just how difficult it has become merely to get a realistic conversation started on issues such as climate change or genetically modified organisms."
Allow me to say this clearly: if you believe there is an active and lively scientific debate about whether humans are causing global warming, you are wrong.
If you think that there is an argument to be made against global warming that has scientific merit, you are wrong.
Scientists around the world in their thousands: Nobel laureates, ecologists, climatologists, they have generally voiced a chorus of agreement with the science of global warming, and the UN Intergovernmental Panel on Climate Change agrees too - which is tough to do, because EVERYTHING the UN does is watered down and made nice and warm and fuzzy for each and every one of its member states.
The voices raised against the idea tend to be economists, lawyers, journalists, and the occasional monovariable-thinking engineer.
In short, if you reject anthropogenic global warming, you are wrong. That's all there really is to say. There is no longer any debate except that created by psuedoscience and mass media bias: i.e., noise.
So, when scientists - whose tenured jobs depend on them toeing the line and keeping their speech apolitical - start saying they are under sustained attack for reporting their findings, we need to stand up and listen.
Go forth and educate!
