1:00 PM | How long do captive killer whales survive?

Scientific American: The Age of Wind and Solar Is Closer Than You Think Great article about progress in alternative energy, but I couldn’t get past the gloomy forecast that fossil fuels will still be prominent for many years to come:According to the International Energy Agency (IEA), the share of global energy provided by renewables—a mere 14 percent in 2012—will increase only slightly between now and 2040, rising to just 19 percent…Though they also argue that there […]

10:20 PM | A great water historian in California’s time of need
UCLA’s Jon Christensen* has written a lovely, loving essay remembering the late water historian Norris Hundley, who wrote so well about western water, and (Jon argues) is important now, in California’s time of need: It’s not for nothing that we often talk of western water wars. What Norris showed is that at times this looked ...Continue reading ‘A great water historian in California’s time of need’ »

9:24 PM | Putting “Nature” Back Into Earth Day, And Taking “The Environment” Out
I put in a lot of long days and sleepless nights studying the planet, and have spent the last twenty years teaching and writing about it, and volunteering for causes to “save” it. And you know what? In honour of Earth Day today I have decided to cull the word “environment” from my vocabulary and […]

salon: Oklahoma started fracking with abandon around 2008, initiating a boom of natural gas and oil production. In 2009, earthquakes stopped being a rarity, as they were in the past. And by 2014, the state had become the new earthquake capital of the U.S., with three times as many magnitude 3 and above quakes than the former record holder, California. Tuesday, state officials finally acknowledged the connection.The state geological survey officially “considers it very likely” that […]

6:31 PM | Barcoding local - Contributions by course participants (1)
The Introduction to DNA Barcoding course I am teaching is in its final week but we have already lined up another one running from June 1 to July 24, 2015.

This is one of the highlights of the course for me as it provides me with some unique insights into the work of colleagues world wide but it also shows me how well I did with […]

E-Waste Facts and ThoughtsA recent report found that in 2014, humans tossed out 92 billion pounds of e-waste! That got me wondering - and googling.

Some of the constituents, such as lead, nickel, cadmium, and mercury, could pose risks to human health or the environment if mismanaged at their end-of-life…” (- […]

4:57 PM | Whale Alert 2.0: Mobile App Helping Save Whales with Citizen Science
Large whales are vulnerable to collisions with vessels throughout the world's oceans. North Atlantic right whales inhabit the coastal waters of the Eastern Seaboard of North America, and their migratory route between their feeding grounds in the Northeast and their calving ground in the Southeast passes some of the busiest ports in the US. This makes harmful and often deadly vessel interactions

Here are the life cycles of three different plastic bottles.Bottle One, like hundreds of millions of tons of its plastic brethren, ends up in a landfill. This huge dump expands each day, as more trash moves in and continues to take up space. As plastics sit there being compressed, rainwater flows through the waste and absorbs the water […]

12:00 PM | Why do village dogs eat endangered sea turtle eggs?
Feral and outdoor cats kill millions of birds each year, proving that when humans encroach on wildlife habitats, the risks to wildlife aren’t strictly human in origin. With humans come our domesticated pets. Cats get a bad rap, and perhaps they deserve it, but dogs aren’t entirely free from blame either. Domestic dogs are perhaps

8:03 AM | Review: Weather@Home wireless weather station
Checking the weather from the comfort of the sofa This is a chancy time for gardeners. Spring has arrived, and we’re getting some sunny days that can easily cook any seedlings that are left in an unopened cold frame for the day. But there’s still the risk of frost at night. Keeping an eye on the weather forecast is a necessity. If you tend to watch the tv news, or listen to the radio, then the weather forecast comes to you. If you rely on the internet, or an app, then you have to […]
