Nero was an emperor of Rome, and not looked upon kindly by history. A great fire swept through Rome, rumored to have been started by Nero himself to clear more land for his own estate. Nero supposedly did little to stop it, which is why we have the phrase "Nero fiddled while Rome burned". The analogy to climate change is glaringly obvious. The burning of fossil fuels such as coal and oil has dumped vast amounts of carbon dioxide into the air - far more than the total from all volcanoes combined, for example. This greenhouse gas essentially traps heat*, preventing natural physical processes from letting the Earth maintain its temperature. The end result: the Earth is heating up. The vast, overwhelming majority of real climate scientists agree with this assessment. Oddly, the fossil fuel industry doesn't. They sponsor a lot of very loud and very wrong "think tanks" who deny the very existence of the problem the industry itself created. So the Earth heats up, and they fiddle with the truth. As I wrote recently, global warming is in the news because it's very likely that the hurricane Sandy was influenced by our changing climate. I'm not the only one to think so. Climate scientist Randy Horton says, for example, that melting sea ice and a declining jet stream may have been in part responsible for steering Sandy into the east coast, instead of over the open ocean as late-season hurricanes usually do. The deniers, of course, are spinning this faster than the hurricane itself.
Those of us on the side of reality in this issue want it to be about science, but we must see that it's about politics. When a large number of sitting members of the US House of Representatives science committee are avid and avowed global warming deniers, this is about politics. When we see the fossil fuel industry funding those very people, it's about politics. Perhaps that stranglehold of political denial is loosening up a tiny bit. Business Week, not usually known for leftist leanings, just published a story called "It's Global Warming, Stupid" and put it on their front page. The two presidential candidates have hardly talked about it, and not at all in the debates, despite this being the biggest medium-term crisis the world is facing. President Obama did finally speak out, on MTV of all places (which is actually pretty good; hopefully a younger audience will listen), but could've put in a lot more details of what he actually plans to do. Of course, Governor Romney is wearing his past statements like an albatross around his neck. He has mocked global warming, and said many times he would dismantle FEMA. He flip-flopped on that just this week, kindof, saying FEMA does an important job. However, given that he said it was "immoral" - his word - to fund FEMA, I have a difficult time believing he's being entirely honest now. Because the issue was ignored in the debates, Science Debate put on a mock 4th Presidential debate dealing with global warming, with candidate stand-ins talking about the issue. If only that had been real. If only. So we still have a long way to go. Things in the Senate aren't much better, with people like James Inhofe (R-OK) still sticking by his claim that the very idea of global warming is a hoax. Happily, some people are willing to hang that one around his neck, too. But it's not enough. Not nearly. And there's more bad news. One of the biggest weapons we have against hurricanes like Sandy is our fleet of weather satellites, tracking the storms and allowing scientists to predict the path and ferocity of storms, sometimes days in advance. Sandy's track was predicted amazingly well due to this. But our very ability to do this is in jeopardy: the New York Times is reporting that we may be facing a weather satellite crisis, with an aging fleet of satellites breaking down and no replacements ready for launch for quite some time. There may be a years-long gap in our coverage of storms from space because of this. And during all of this, the deniers fiddle. They argue and spin about statistics, misleadingly plotting data. They talk about sunspots, they talk about cycles, they talk about other planets, and all the while they are desperately trying to distract you from the real issue. The Earth is warming up, the change is real, it's dangerous, it's already affecting us noticeably, and we're not doing anything to stop it. The public is catching on to this. Recent polls show that Americans are more accepting that global warming is real. That's good news, and an excellent start. But it must be translated into action. We have an election coming up in a few days. Many of these climate change deniers are up for re-election, while others are seeking office. If you are an American, I urge you to do your research and vote accordingly. Literally, our future is in our hands. <em<Image credit: NOAA/NASA GOES Project
^* Technically, CO2 is transparent to visible light, but opaque to far infrared. Sunlight gets through, warms up the ground, which then radiates that heat as infrared. The CO2 won't let that radiate away into space, so the heat stays on Earth, warming the ground (and oceans!) further. But saying "it traps heat" is close enough.
