Coal industry asks for still more handouts, and Washington lends an ear
We’re gradually learning how the U.S. government will approach our country’s energy needs in the carbon-constrained future — and if you were envisioning a future free of mining the earth for dirty energy, you should probably check the optimism. Same coal, same coal. Photo: iStockphoto Two important hearings on Capitol Hill earlier this month strongly […]

Umbra on global warming and you
Dear Umbra, I love the scientific ins and outs, really I do, but what oh what can we do about global warming? And I mean us ordinary folks with a house and mortgage and some percentage point of kids and a few compact fluorescents and maybe even a hybrid in the driveway. We’re right there […]

Umbra on water vapor and climate change
Dear Umbra, Coming from a scientific background, I was under the assumption that water vapor was the worst — or you could say the best — at causing global warming. Do you believe this to be false, and if not, why is no one talking about it? Erik Nash Dearest Erik, I’ve decided to use […]

Umbra on the greenhouse effect
Dear Umbra, Man-made greenhouse gases are blamed for recent global-warming trends. But man-made greenhouse gases account for only 5 percent of the greenhouse effect. Water vapor, over which civilization has virtually no control, accounts for some 95 percent of that greenhouse effect. Why has so much attention been focused on man-made gases when they comprise […]

I think it might help us all get better educated on this vital topic. Even if they don’t spend an hour of their Earth Day sifting through the […]

If I start thinking about moving my family to another country, […]

Umbra on climate-change patterns
While I am in no doubt about the effect of human activity on climate change, I have a friend who is convinced that even if we weren’t destroying the earth, the earth’s own weather patterns would be in global-warming stage anyway. How do we know the current climate change isn’t just an inevitable part of […]

Umbra on global warming
Dear Umbra, The many articles on global warming conclude with something about the inherent complexity and uncertainty of the issue. So exactly what is the evidence for (and against) arguing that the current warming trend is inside the scope of normal fluctuations? What is the evidence for (and against) arguing that the trend is caused […]
