9:03 PM | The ‘Equal Streets’ Movement in Mumbai
Roads are a significant aspect of a city’s environment, both in terms of the area they occupy as well as their socio-environmental condition. In Mumbai for example, nearly 2000 km of roads occupy approximately 40 km2 of land. This is … Continue reading →

5:04 PM | The Jargonaut: Why Is There GRAS in My Food?
By Brian Palmer Editor’s note: If you follow environmental science and policy (or just dip a toe in every once in a while), you’re bound to encounter obscure terms and wonky jargon. OnEarth is here to explain them to you, in this new feature we call The Jargonaut. Many of the things you eat and drink have never been formally tested, because, as the Washington Post just highlighted in a major front-page story, the U.S. Food and Drug […]

2:18 PM | Doesn't Take a True Detective to Spot an Industrial Wasteland
By Jason Bittel HBO’s True Detective took home an Emmy last night for best directing in a drama series. If you haven’t watched the show yet, we highly recommend you marathon it. As you can see from this gritty intro, True Detective is about the environmental devastation wrought on Louisiana by an unfettered oil and gas industry—a dark allegiance of greed and smoke and ruin. Just kidding! It’s about two detectives (bad-ass versions of […]

1:30 PM | After Record-Breaking Rim Fire, Log Trees or Leave Them?
Later this week, the U.S. Forest Service will release plans to allow logging companies to harvest some of the dead trees. Some environmental groups say it would destroy important wildlife habitat.

1:26 PM | #10: Where did they go??
Dan and Bill looking for whales in glassy sea. Photo: Marilyn Marx Sunday was a stunningly beautiful day out in the Bay of Fundy--a glass calm sea state and excellent visibility. With the three vessels mentioned in our last blog: Nereid, Callisto and Selkie we did an extensive survey. We could see for miles and found humpbacks, fin whales, molas, dolphins and basking sharks, but no right

1:00 PM | Is there a deforestation limit we can aim for?
Deforestation is bad, according to just about everybody in the world who isn’t actively engaged in cutting down a tree right now. It isn’t a controversial position to say that we should save our rain forests and other major wooded areas, but it also isn’t a particularly useful one. A more interesting question to answer

8:46 AM | Constructive and External Validity for Climate Modeling
It’s been a while since I’ve written about the question of climate model validation, but I regularly get asked about it when I talk about the work I’ve been doing studying how climate models are developed. There’s an upcoming conference organized by the Rotman Institute of Philosophy, in London, Ontario, on Knowledge and Models in […]

2:07 AM | Blog for kids
Only intermittent posting these days as I have a few day off - well deserved vacation.Today just an announcement - Last week I started a new blog. One bug a day is made for kids. Every weekday a new bug, starting with the ones I find in my backyard, on walks or hikes, or simply at home. The idea is certainly not new and that's why added a little twist to it. Every post has about 150-200 words which is equivalent to about one minute of reading. The idea is to engage kids in their natural […]

8:47 PM | Fight My Fire
By Brian Palmer We ought to rename the U.S. Forest Service the “Forest Fire Service,” because pretty soon fighting fires is all that the agency will be able to do. Since 1995, the proportion of its budget spent on fire suppression has risen from 16 to 42 percent, according to an Agriculture Department analysis released last week. If you include secondary costs related to firefighting (such as fire suppression research), the agency now spends the […]

7:27 PM | Local Water Woes, No More? Advancing Safe Drinking Water Technology
By Ryann A. Williams As a child growing up in Washington, D.C. I remember hearing adults talk about their concerns about the local tap water. Overheard conversations about lead content and murkiness in the water certainly got my attention. As an adult who now works at the Environmental Protection Agency, I know things have greatly […]

4:00 PM | A Glimpse of LUCA, Life’s Last Universal Common Ancestor
A new study suggests how early life might have survived without some of the cellular machinery that is absolutely required for life today. Turns out that having a fairly leaky membrane may have been the key.

2:23 PM | The Early Grouper Gets the Shark
By Jason Bittel As you may have guessed from its name, the goliath grouper can grow to massive proportions—up to eight feet and 800 pounds. Unfortunately, we nearly caught, speared, and ate the species into extinction in the 1980s. This, um, photogenic fish has rebounded a bit since then, but the Atlantic goliath remains on the Endangered Species List. Why am I yammering on about big groupers? Oh, because one just gulped down a four-foot shark like […]

By Marc Oliva   The Mediterranean Environmental Research Group, (GRAM) from the University of Barcelona has over 20 years of working experience in the field of the effects of forest fires on soil properties. In 1998 the doctoral thesis entitled “Fire effects on soil properties, the role of fire intensity” carried out by Xavier Úbeda […]

2:14 PM | Reclaimed water
I don’t know whether to view these signs all over Tucson’s golf courses proclaiming their use of “reclaimed” water as proud – “We’re water smart!” or defensive. But whenever the conversation veers toward water “reclamation”, always ask yourself where that water might have gone if you hadn’t, for example, put it on this golf course. ...Continue reading ‘Reclaimed water’ »

1:56 PM | Questions about the Gila Diversion
In the Colorado River Basin writ large, 14,000 acre feet of water is a very small rounding error – less than one tenth of one percent of the river’s flow. But the New Mexico discussion over the possibility of a diversion high in the watershed of the Gila River in New Mexico, raises fascinating questions ...Continue reading ‘Questions about the Gila Diversion’ »

12:34 PM | Holding a Beloved Figure Accountable for False Claims
In 2002, the global GMO discourse chagrined anthropologist Glenn Davis Stone: Western audiences have been bombarded with deceptive rhetoric, spin, and soundbite science portraying the wonders—or horrors—of the new technology. He blamed both the biotech industry and anti-GMO activists for exploiting food security concerns to advance their own agendas. The article, published in the journal Current Anthropology, […]The post Holding a Beloved Figure Accountable for […]

8:48 AM | Volcanoes and climate change
What happens to the atmosphere when volcanoes erupt? Can volcanic eruptions lead to climate change? In 2010 the eruption of Eyjafjallajökull in south Iceland brought air traffic in northern Europe to a standstill for almost seven days. Now, the Bárðarbunga volcano, which has erupted beneath the Dyngjujökull glacier in central Iceland, is being intensively studied by scientists. On average, there are around 50-60 volcanic eruptions around the world each year. When volcanoes […]

7:55 AM | An edible archway
An archway into a pergola at the Cotswold Wildlife Park Ryan and I went to the Cotswold Wildlife Park and Gardens last weekend, which is a nice day out if you’re in the area. (If you book online you save a little bit of money, and some time at the ticket kiosk – tickets are valid for one month from purchase.) The animals are great; there’s always a crowd around the meerkat enclosures, and there’s plenty of cute things on show. There was a man doing a falconry display […]

9:16 PM | Mulroy: Lake Mead’s bathtub ring is not just Las Vegas’s problem
Former Southern Nevada water chief Pat Mulroy explains that, while Las Vegas is an easy rhetorical landing spot because it is right next door to Lake Mead, the dropping Colorado River reservoir is a basin wide issue: What we are experiencing is not a Las Vegas problem — it is truly a regional problem that ...Continue reading ‘Mulroy: Lake Mead’s bathtub ring is not just Las Vegas’s problem’ »

4:57 PM | What a difference a week makes!
While some of the team is offshore, a few of us have stayed in Lubec to continue surveying the Bay of Fundy.  We had two good days out on Wednesday and Thursday but the number of whales had dropped significantly since last week’s surveys. Even with thorough coverage (by 3 research vessels: Nereid, Callisto and Selkie) in calm seas only seven whales were photo’d in the two days.  That's quite a

8:51 AM | Independent nurseries
Victoriana Nursery Gardens, in Kent I ordered some plants yesterday, from Thompson & Morgan. I’d seen their new ‘patio’ raspberry, ‘Ruby Beauty’, and took advantage of their Bank Holiday free P&P offer. It was ideal for me because I fancied buying some plants, but since I don’t currently have a garden I am struggling to keep plants alive. My new raspberries should arrive after we’ve moved in to the new house, and give me something to play […]

10:14 PM | 3D printing a better lab
The 3D printer is already proving useful after just one week in the lab. It’s now so easy to make custom objects I am seeing lots of opportunities to use the printer in the lab instead of cobbling together random odds and ends. In the last few days I have been designing labware …

7:20 PM | Novel Ecosystems - a really bad idea?
Novel ecosystems arise when human activities change biological communities e.g. through species invasions or environmental change. Many policymakers and ecologists consider them acceptable or even see them as new normal ecosystem because they appear ubiquitous. Some proponents of the concept assert that because of the global nature of climate change, all ecosystems are at risk of transformation by extinctions and invasions. Moreover, the pervasiveness of the human footprint suggests to […]
