Oceans warming faster than thought, says research

The world’s oceans have warmed 50 percent faster over the last four decades than what was previously thought, according to a new study published in Nature. The new research helps to explain recent sea-level rise that climate models weren’t accounting for; melting ice gets all the press, but since heat expands, hotter water also contributes […]

Considering recycled energy will politically facilitate a national clean energy plan

There is a tendency to frame the politics of clean energy as a debate between the enlightened, forward thinkers on the coasts and the paleolithic environment-hating coal barons in the Southeast and Midwest. It makes a good sound bite, but confuses the ends and the means. Yes, there are strong vested interests in the coal belt and the rust belt that consistently resist GHG caps and clean energy policy. But so long as we frame the clean energy conversation as a wealth transfer from dirty states to clean states, our success will remain contingent upon our ability to get senators, representatives, and voters in those states to act against their near-term economic self interest.

Three maps below clarify the problem, and suggest a solution.

Corn utensils not helpful without widespread public composting

As an alternative to non-recyclable plastic and Styrofoam, some restaurants have begun offering corn-starch-based utensils and takeout containers. But does cornware really provide a guilt-free way to eat your vegesustainorganaturalocal meal? Though touted as compostable, corn-based utensils can’t just be thrown into your garden; they don’t biodegrade unless professionally composted at high temperatures. Thus, customers […]

Short-term high gas prices (hopefully) mitigate long-term environmental disasters

I have been reading Sean Casten's post on the economics of carbon pricing with interest. After some thought, here's my take. A carbon tax or a cap-and-trade system will, without question, raise the price of energy, at least in the short term. In the long-term, it may well be that technological developments lead us to new energy sources that turn out to be cheaper than anything we have today. But that's pure speculation.

But in the short term, the costs of a carbon tax or the costs of permits in a cap-and-trade system will follow the energy through the system and eventually raise prices at the consumer level. So prices will increase.

But that fact is a distraction. The real issues are, first, how much will prices rise, and second, what will happen if we do nothing?

New research correlates mass extinctions with the rise and fall of oceans

New research finds that the "rise and fall of ocean levels correlated more consistently with mass extinctions than any other factor." Published in Nature this week, "Environmental determinants of extinction selectivity in the fossil record" ($ub. req’d) explores "the close statistical similarities between patterns of marine shelf sedimentation and rates of extinction.”

On our current emissions path, the planet’s temperature by 2100 will be more than 4.5°C hotter than today, hotter than it was the last time the world was ice free and sea levels were some 250 feet higher (see here). This research supports the IPCC prediction that as global average temperature increase (PDF) exceeds about 3.5°C (relative to 1980 to 1999), model projections suggest significant extinctions (PDF) (40-70 percent of species assessed) around the globe.

But really, who needs other species anyway? What have they ever done for us?

Umbra on the never-ending diaper ado

My Sweet Umbra, The diaper debate continues! I’ve read Grist’s position, and I even saw the same answer posted in your FAQs, which means I’m not supposed to be asking you about it again (all change has been effected by those of us who challenge the system!). The thing is, I disagree vehemently with your […]

Jellyfish are everywhere, and that’s not a good thing

Photo: Neil Harmon The natural cycle of Mediterranean jellyfish populations is to swell every 12 years, plateau for four to six years, then subside. But massive groups of gelatinous jellies have been showing up for the past eight years, and they show no sign of flagging. In fact, jellies are proliferating worldwide, and that makes […]

Hm, oversold by who?

“[Carbon capture and sequestration] as a magical technology that solves the carbon problem for coal plants is oversold. … I think there is a lot to learn, and it is going to take us a lot longer for us to figure it out than a lot of us think.” — Duke Energy CEO Jim Rogers

Go get your grassroots on

350.org has officially launched, in eight languages. Grassroots actions are now being planned around the world, from the Great Wall of China to the Eiffel Tower. Here’s a fantastic video: For more on 350, see: Bill McKibben on the need for 350ppm as a global target Bill McKibben on the kick-off of 350.org Me on […]

Four short films explore how climate change affects women worldwide

“Is climate change a feminist issue?” NewScientist enviro blogger Catherine Brahic asked last week, then answered, “[F]or me, climate change is not a gender issue. Climate change will not affect women more than men.” She was responding to several short films Oxfam recently produced that profile four women in Brazil, Uganda, the U.K., and Bangladesh. […]
