This year ushered in a series of intense weather events that impacted communities across the globe: record-breaking heat waves; super-charged cyclones; intense flooding; coastal waters hitting a balmy 38°C (1–4). Attributing extreme weather to climate change has become the norm when reporting on these seemingly more frequent and intense events. But beyond simply acknowledging weather to be more violent or destructive than it was in the past, how is it that climate experts are able to determine if increasing greenhouse gas levels are the culprit behind these extreme weather events? The answers can be found in climate attribution science.Continue reading “How do Scientists Connect Extreme Weather Events to Climate Change?”
Earlier this year, I had an opportunity to attend a virtual talk presented by leading climate scientist and communicator Dr. Katharine Hayhoe. She began by asking the audience to send in one word that describes how they feel when thinking about climate change. The responses popped up live in a word cloud on Hayhoe’s shared screen:
ARGHH!Continue reading “Making Sense of Climate Change”
Komodo Dragons are not only the largest lizard on Earth but also one of the most ferocious species with a fearsome reputation. The carnivorous beast can grow up to 10 feet long and can detect flesh from miles away. However, the Komodo Dragon’s serrated teeth, armored scales, and venom-laced saliva are still being outmatched by its biggest competitor: extinction.
The Komodo Dragon was previously named a “vulnerable” species by the conservation organization before being reclassified as “endangered.” There is hope that this change in status will encourage policymakers and conservation groups to strengthen and expand protections.Continue reading “Fighting Extinction: Komodo Dragons At Risk”
With average sea surface temperatures increasing around the world, coral bleaching events are growing in extent and severity. More than two thirds of the corals in the Great Barrier Reef, the world’s largest coral reef, have already bleached. While the physiological consequences of coral bleaching are well-studied, we still don’t fully understand how bleaching happens on a cellular level.
Steve Palumbi at Stanford University is delving deeper into the mechanisms by which coral bleaching occurs. In 2018, Promega pledged $3 million over three years to the nonprofit Revive & Restore Catalyst Science Fund, to identify and develop advanced techniques for conservation, enhancing biodiversity, and genetic rescue. Palumbi was awarded the first grant from this fund to study the genomic stress trigger that causes corals to bleach in warming oceans.Continue reading “Anti-Cancer Drugs Are Pro-Coral”
A startling report from researchers in Washington indicates that the increasingly acidic waters of the United States Pacific Northwest are turning sea cucumbers into sea pickles.
Dennis Dimick has focused his journalism career on the collision between human aspiration and the planet. The son of fisheries biologists, Dimick grew up on a farm in Oregon’s Willamette Valley, and he holds degrees in agriculture and agricultural journalism from Oregon State University and the University of Wisconsin-Madison. In his 35 years at National Geographic, he served for over a decade as the magazine’s environment editor, and guided major projects on climate change, energy, freshwater, population, and food security. Dimick is co-founder of Eyes on Earth, a project meant to inspire a new generation of environmental photographers.
As a young man, Dimick witnessed firsthand the price of progress when his family’s farm was cut in half by the construction of an interstate beltway. This invasion of their farm, in addition to the clear-cut logging of nearby forests where Dimick had spent his youth, combined to sensitize him to the profound impacts of human progress on the Earth. Early photography experience and his personal connection to the effects of human progress led to a life and career spent combining these two dimensions.
In anticipation of his participation in the 2018 Wisconsin Science Festival, I asked Mr. Dimick some questions about photojournalism, and what it’s like documenting the human impact on the environment. Some of his answers have been slightly edited for clarity.
What does it take to be a good environmental photographer? Continue reading “Living in the Anthropocene: A Photojournalist’s Perspective”
It seemed like the rain was never going to stop. It started in the morning, and when I left work around 5pm, it was still coming down hard. I took my normal route home through a back country road. As I turned right onto Fitchrona Road, a long line of cars came into view. There’s usually some congestion leading to the stop sign ahead. Except today, something was different. About 20 yards of the road ahead was submerged in water. Continue reading “My City Flooded, and There’s More to Come”
