When you see lawmakers like Senator Jim DeMint of South Carolina tweeting that “it is going to keep snowing until Al Gore cries ‘uncle,’” or news that the grandchildren of Senator James Inhofe of Oklahoma are building an igloo next to the Capitol with a big sign that says “Al Gore’s New Home,” you really wonder if we can have a serious discussion about the climate-energy issue anymore. […]

Although there remains a mountain of research from multiple institutions about the reality of climate change, the public has grown uneasy. What’s real? In my view, the climate-science community should convene its top experts — from places like NASA, America’s national laboratories, the Massachusetts Institute of Technology, Stanford, the California Institute of Technology and the U.K. Met Office Hadley Centre — and produce a simple 50-page report. They could call it “What We Know,” summarizing everything we already know about climate change in language that a sixth grader could understand, with unimpeachable peer-reviewed footnotes. […]

Here are the points I like to stress:

1. Avoid the term “global warming.” I prefer the term “global weirding,” because that is what actually happens as global temperatures rise and the climate changes. The weather gets weird. The hots are expected to get hotter, the wets wetter, the dries drier and the most violent storms more numerous. The fact that it has snowed like crazy in Washington — while it has rained at the Winter Olympics in Canada, while Australia is having a record 13-year drought — is right in line with what every major study on climate change predicts: The weather will get weird; some areas will get more precipitation than ever; others will become drier than ever.
    
2. Historically, we know that the climate has warmed and cooled slowly, going from Ice Ages to warming periods, driven, in part, by changes in the earth’s orbit and hence the amount of sunlight different parts of the earth get. What the current debate is about is whether humans — by emitting so much carbon and thickening the greenhouse-gas blanket around the earth so that it traps more heat — are now rapidly exacerbating nature’s natural warming cycles to a degree that could lead to dangerous disruptions.
    
3. Those who favor taking action are saying: “Because the warming that humans are doing is irreversible and potentially catastrophic, let’s buy some insurance — by investing in renewable energy, energy efficiency and mass transit — because this insurance will also actually make us richer and more secure.” We will import less oil, invent and export more clean-tech products, send fewer dollars overseas to buy oil and, most importantly, diminish the dollars that are sustaining the worst petro-dictators in the world who indirectly fund terrorists and the schools that nurture them.
    
4. Even if climate change proves less catastrophic than some fear, in a world that is forecast to grow from 6.7 billion to 9.2 billion people between now and 2050, more and more of whom will live like Americans, demand for renewable energy and clean water is going to soar. It is obviously going to be the next great global industry.
