Go With The Flow
Have you ever wondered what happens when a fish encounters a dam or a culvert? Too often, these structures are barriers to breeding and nursery sites, feeding grounds, and vital genetic mixing. In a warming world, barriers also prevent fish from seeking refuge as stream temperatures change.
Fir Trees And Butterflies
We have done a number of stories about the sad state of the monarch butterfly and how their numbers have dropped from a billion to only 33 million as of a couple of years ago. Biologists in the U.S. have been trying to restore the summer habitat of the butterflies by urging the planting of milkweed, which is the primary host plants for monarch butterfly caterpillars.
Japan’s Hydrogen Future
Japan is a country seeking energy independence as well as environmental credibility. It has grappled with nuclear disaster at Fukushima and is currently the sixth largest emitter of greenhouse gases in the world.
The Hottest Year
2015 was the hottest year in the historical record, easily breaking the mark set only one year earlier. The unusually large El Niño weather pattern is releasing enormous amounts of heat from the Pacific Ocean into the atmosphere, but climate scientists say that the bulk of the record-setting heat is due to the long-term warming effects of greenhouse gas emissions. The global land surface temperature was 1.6°F above the 20th century historical average. That’s a huge jump from 2014, which was 1.3° above average. That may sound like very little, but for the planet as a whole, it is extremely large.
Fungal Diseases And Wildlife
Since the late 1990s, there has been an unprecedented global wave of virulent fungal infections that has been decimating whole groups of animals from salamanders and frogs, to snakes and bats.
Plastics And Our Oceans
Almost everyone everywhere comes into contact with plastics everyday. Their use has increased 20-fold in the past half-century, and production of the “ubiquitous workhorse material of the modern economy” is expected to double again in the next 20 years. Nearly one-third of all plastics are not properly disposed of or recycled.
Coexisting With Dangerous Carnivores
We come across many things that we don’t like but that are nonetheless good for us or good for the world in general. On some level, we all make cost-benefits analyses to decide what to do about various things that we might just as soon do without.
Climate Change And Buzzards Bay
The effects of climate change are being felt around the world, including in some well-known places in the Northeast. Buzzards Bay is a popular destination for fishing, boating, and tourism adjacent to Cape Cod in Massachusetts.
British Columbia’s Carbon Tax
The recent Paris summit on climate change produced a global treaty to reduce greenhouse gas emissions. There are multiple strategies to reduce emissions including both technological and economic ones.
Arctic Ecosystems
Most of us are aware that shrinking ice cover is bad news for Arctic wildlife, with animals like polar bears and seals losing important breeding, nursery, and feeding grounds. What has received less attention is the impact ice loss has on life in Arctic waters. [Read more…] about Arctic Ecosystems
We Like Cheap Gas
The major auto makers agreed several years ago to a goal of achieving average fuel economy of over 54 miles per gallon by 2025. Motivated by the desire to reduce emissions, getting twice as many miles out of a gallon of gas makes great sense.
De-Icing Roadways
We have been using salt to keep winter roads free of ice and snow since the late 1930s. In the United States alone, some 20 million tons of salt are applied to roadways each year. And while its use has real benefits in terms of safety and navigation, there have been cumulative costs to the environment, including degrading freshwater resources and contaminating groundwater.
Preservatives
Augmenting food with preservatives is not a recent practice. For thousands of years, we have canned fruits with sugar, preserved meats with salt, and pickled vegetables so that they could keep in hot humid environments.
Lake Ohrid: Respecting An Elder
Nestled in the mountainous border between southwestern Macedonia and eastern Albania, Lake Ohrid is a deep, ancient lake. Its waters provide refuge to hundreds of plants and animals that live nowhere else, including seventeen species of fish.
