Stephen Buchmann is a pollination ecologist specializing in bees, and an adjunct professor with the departments of Entomology and of Ecology and Evolutionary Biology at the University of Arizona. He draws on his experience studying bees for almost 50 years to explore how these creatures perceive the world and their amazing abilities to navigate, learn, communicate and remember. Here’s some of what I’ve learned.
El Niño is coming, and ocean temps are already at record highs – that can spell disaster for fish and corals
During El Niño, a swath of ocean stretching 6,000 miles (about 10,000 kilometers) westward off the coast of Ecuador warms for months on end, typically by 2 to 4 degrees Fahrenheit (about 1 to 2 degrees Celsius). A few degrees may not seem like much, but in that part of the world, it’s more than enough to completely reorganize wind, rainfall and temperature patterns all over the planet. White corals indicate bleaching from heat stress. Marine heat waves can trigger coral bleaching. Dillon Amaya is a climate scientist who studies the oceans. After three years of La Niña, he advises that it’s time to start preparing for what El Niño may have in store.
What’s going on with the Greenland ice sheet? It’s losing ice faster than forecast and now irreversibly committed to at least 10 inches of sea level rise
Alun Hubbard is a field glaciologist who has worked on ice sheets for more than 30 years. The past few years in particular have been unnerving for the sheer rate and magnitude of change underway. Current teachings that ice sheets respond over millennial time scales is definitely not what we’re seeing today. If every year were like 2012, when Greenland experienced a heat wave, that irreversible commitment to sea level rise would triple. That’s an ominous portent given that these are climate conditions we have already seen, not a hypothetical future scenario.
Light pollution is disrupting the seasonal rhythms of plants and trees, lengthening pollen season in US cities
City lights that blaze all night are profoundly disrupting urban plants’ phenology – shifting when their buds open in the spring and when their leaves change colors and drop in the fall. New research Yuyu Zhou coauthored shows how nighttime lights are lengthening the growing season in cities, which can affect everything from allergies to local economies. In the study, Zhous and his colleagues analyzed trees and shrubs at about 3,000 sites in U.S. cities to see how they responded under different lighting conditions over a five-year period. Plants use the natural day-night cycle as a signal of seasonal change along with temperature.
Matthew E. Kahn studies environmental economics, and in his recent book, “Adapting to Climate Change: Markets and the Management of an Uncertain Future”, he explores how the rise of Big Data will help people, firms and local governments make better decisions in the face of climate risks. He sees the emergence of a climate risk analysis industry for real estate as a promising development, but believe the federal government should set standards to ensure that it provides reliable, accurate information.
Morgan Bazilian and Dolf Gielen both with the Colorado School of Mines, have identified four strategic priorities that would help provide the foundations for success in both the energy and climate change domains.
IPCC climate report: Profound changes are underway in Earth’s oceans and ice – a lead author explains what the warnings mean
Humans are unequivocally warming the planet, and that’s triggering rapid changes in the atmosphere, oceans and polar regions, and increasing extreme weather around the world, the Intergovernmental Panel on Climate Change warns in a new report. The IPCC released the first part of its much anticipated Sixth Assessment Report on Aug. 9, 2021. In it, 234 scientists from around the globe summarized the current climate research on how the Earth is changing as temperatures rise and what those changes will mean for the future. This is a conversation with climate scientist Robert Kopp, a lead author of the chapter on Earth’s oceans, ice and sea level rise, about the profound changes underway.
Privacy and security issues impact every aspect of our lives – home, work, travel, education, health and medical records – to name but a few. On a weekly basis Pete Weiss highlights articles and information that focus on the increasingly complex and wide ranging ways technology is used to compromise and diminish our privacy and security, often without our situational awareness.
