Umbra on talking to friends about climate change
Dear Umbra, I need a good stick-it-to-ya comeback to friends who, while they acknowledge global warming and hear me rattle off all that is bad about it, are liking the direct effects, which right now are sunnier and warmer days. What can I do or say to get them to snap back into reality, especially […]

Umbra on plants and global warming
Dear Umbra, My simple understanding of global warming is that we are introducing long-buried carbon dioxide into the atmosphere. This is shifting the balance, leading to a host of undesirable issues. CO2 is consumed by plants, so here’s my thought: Could we grow crops that consume a lot of CO2 (I’m thinking bamboo here, which […]

Umbra on climate confusion
Dear Umbra, Any chance that the most extreme of the peak-oil folks are correct, and that in spite of our thoughtlessness, we just won’t have enough oil to totally destroy the ozone layer? Dan WassonPittsburgh, Penn. Dearest Dan, Oil has very little to do with the ozone layer, but it does have to do with […]

In a warmed world, even food won’t be as good for you
Humanity is on the threshold of a century of extraordinary bounty, courtesy of global climate change. That’s the opinion of Robert Balling, former scientific adviser to the Greening Earth Society, a lobbying arm of the power industry founded by the Western Fuels Association. In a world where atmospheric carbon dioxide levels soar from the burning […]

Umbra on reducing emissions, one person at a time
Dear Umbra, I want to adopt the Kyoto treaty myself and adjust my lifestyle accordingly. No waiting, and to hell with George Bush! If my nation had adopted it, I’d have to be doing it anyway. So what is my per-capita fossil-fuel ration for the next 10 years, how do I measure it, how do […]

Umbra on how climate change will affect us
Dear Umbra, My girlfriend asked me the other day why global warming was going to be so bad for her. I just graduated with a degree in environmental science, and I like to think I learned something in my classes, but I still struggled to give her a concise, straightforward answer. I see new research […]

Umbra on effective activism
Dear Umbra, If an environmentalist has about six hours per week to devote to activism, what should the person do to make the biggest, most positive impact? Some people (like myself) think that climate protection is a key leverage point — but is it? If yes, why, and what is the best way activists can […]

Top 100 science stories of 2004
Discover Magazine's January 2005 issue features a list of the 100 most important scientific discoveries and developments of 2004. The number one story? Global warming. Called "Turning Point," the magazine's three-page feature says that climate change evidence became overwhelming in 2004, and recalls many of the year's headlines, including Russia's signing of the Kyoto Protocol, the premiere of the blockbuster movie The Day After Tomorrow, and Schwarzenegger's vow to defend California's limits on CO2 emissions. It claims hopefully that "it's only a matter of time before the rising tide of evidence washes over the last islands of resistance in Washington." Well, I don't know about that, but greenies should feel heartened to know that a good number of environmental stories are represented in the top 100. Perhaps someone out there is listening.
