Syndicated columnist George Will's latest piece, “Climate change's instructive past” is more carefully written than previous columns (see Media Matters Misinformer of the Year), but it still requires correction. Contrary to his claim, past changes in our climate should be understood as a warning, but shouldn’t be seen as evidence that current climatic change is naturally occurring, as he suggests.
The problem with this claim is that human-made emissions have increased exponentially since Will’s historical examples. Science has clearly shown how current human-made climate change is very different from earlier slower natural changes, something Will failed to factor.
More accurately, historical climate change provides insight into problems we can expect in the future as greenhouse gases are increasingly amplifying variations in our climate. Historical trends should, instead, serve as a stark warning of what we can expect from the emission-driven warming we’re experiencing now.
