Greenpeace says “Cool IT”

Greenpeace has thrown down the gauntlet (by which I mean mouse pad) and issued the Cool IT Challenge, “a campaign to turn IT industry leaders into climate advocates and solution providers.” From their About page:

This website exposes the gap between what the IT industry could do to fight climate change, and what they’re doing today. . . . → Read More: Greenpeace says “Cool IT”

Graph of the week

Welcome to the first installment of an experiment: The TCOE Graph of the week.[1]

This week’s graph highlights something everyone concenred about climate chaos (including me) should keep in mind: The issue doesn’t begin and end with CO2. Yes, CO2 is the most important single greenhouse gas, but other gases, including methane, nitrides of oxygen, and . . . → Read More: Graph of the week

The perils of faux moral judgments

We need to use a lot less oil and emit a lot less CO2. I doubt anyone who regularly reads this site would seriously debate those assertions. As we see so often, the truly interesting issues arise only in the follow-up questions: What do we cut? Who has to make which lifestyle changes . . . → Read More: The perils of faux moral judgments

From the Summary:

Water is our most fundamental natural resource, a resource that is limited. Challenges to our nation’s water resources continue to grow, driven by population growth, ecological needs, climate change, and other . . . → Read More: Document alert: USGS and water

MIT’s latest climate chaos estimate

Another day, another depressing “it’s worse than we thought” story…

Green Car Congress: New MIT Analysis Finds Global Warming Could Be Double Previous Estimates:

A new comprehensive MIT study of the probabilistic projections of climate change in this century found that absent aggressive intervention, warming will likely be about twice as severe as previously estimated by the MIT . . . → Read More: MIT’s latest climate chaos estimate

Assumptions abound

If there’s one thing people take away from this blog, I would hope it’s an appreciation for the perverse level of interaction between natural and man-made events, and therefore how easy it is to let simplistic assumptions lead us to horribly incorrect conclusions. I was in this frame of mind last night when I saw . . . → Read More: Assumptions abound

Methane checkpoint

I had planned to write this up in a day or two, but after a quick look at the graphic Joe Romm included in his latest poke at climate chaos deniers (which you should read), I felt a bit more urgency.

The graphic in question is from the NOAA, and it shows the latest take on temperature . . . → Read More: Methane checkpoint

Finally, some good(???) news about Antarctica

I’ve seen about a zillion items in my feeds about the news that the potential for sea level rise from Antarctic melting has apparently been overestimated. But it still reads like one of those good news/bad news jokes.

Good News Still Bad On Antarctic Ice Melt:

A new study has found that one of the worst-case scenarios . . . → Read More: Finally, some good(???) news about Antarctica

Lou’s quick graphs

For some time now I’ve kept a minimal HTML file on my system that simply loads a bunch of interesting (to me) graphs of energy and environmental data fro various places on the Intertubes. I finally got a few minutes this weekend (while watching way too much NCAA college lacrosse on TV–GO SYRACUSE!!!) to massage . . . → Read More: Lou’s quick graphs
